1 Electrical System problem of the 2023 Acura RDX

Failure Date: 10/15/2026

This is a follow-up to my earlier complaint about the same vehicle, a 2023 Acura Rdx a-spec advance. In August 2026 the vehicle was stolen from a public street after offenders broke through the exterior driver’s door handle, reached the wiring behind it, and lowered the window to get inside. On oct 15th, offenders attacked the same driver’s door handle on the same vehicle in what appears to be a second attempt using the same method. The handle was broken, but because we spent a lot of money installing more security, the vehicle was not taken. Two attacks on one vehicle in about two months, both starting at the exterior handle, suggest the method is known and repeatable. We have heard this exactly from police and repair shops too. The door’s window and lock circuitry appears to respond to input at the handle area without authentication, so physical access to that point is enough to defeat the locking system and lower all windows. I am a repeat Rdx owner (2008, 2017, and 2023 models) and did not experience this on earlier generations. I ask NHTSA to investigate whether the third-generation door and window architecture is vulnerable, whether other Acura and Honda models share it, and whether a remedy, such as requiring key authentication before the window circuit responds, is warranted. Police reports were filed for both incidents, and I can provide the damaged handle for inspection.

2 Electrical System problem of the 2020 Acura RDX

Failure Date: 09/08/2026

• the media oriented systems transport (most) bus network / fakra coaxial service cable connectors failed. This failure directly controls the primary infotainment assembly and the central safety display screen. The vehicle and its active components are currently intact, fully operational (with the defect present), and available for inspection upon request. • the hardware defect causes sudden, unpredictable total blackouts of the central display screen while driving. This completely disables the safety rearview/backup camera and mutes vital audible driver-assist safety alerts. Additionally, the defect causes extremely loud, jarring, and distracting popping and crackling noises through the audio speakers while moving, creating an immediate driver distraction and safety hazard on public roads. • yes. The vehicle was brought to an authorized Acura dealership service center, where the active symptoms (crackling audio and system instability) were documented. Furthermore, the issue perfectly matches the diagnostic criteria of Acura's official technical service campaign (TSB 23-025). • the vehicle has been inspected at an authorized Acura dealership service department to initiate a corporate claim. However, because the vehicle is just 345 miles past an arbitrary 100,000-mile warranty extension threshold, Acura corporate has refused to perform the physical repair, meaning the defective factory components are still currently installed in the vehicle. • there were no traditional dashboard warning lights or error codes prior to the failure. The primary symptoms are loud audio popping, crackling noises, frozen screen menus, and sudden display blackouts. These symptoms began appearing intermittently and escalated in frequency as the vehicle approached its current mileage of 100,345 miles.

3 Electrical System problem of the 2023 Acura RDX

Failure Date: 09/03/2026

On September 3, 2026 at approximately 1 am, my 2023 Acura Rdx a-spec was stolen from my residence while both of my authorized keys were in my possession. The exterior driver-door key cylinder showed evidence of forced manipulation/damage. Despite the vehicle being locked, the factory theft-deterrent alarm did not activate and I did not receive an Acuralink theft/alarm notification. The vehicle was successfully entered, started, and driven away without an authorized key in the thief’s possession. After the vehicle was recovered, I contacted Acura client relations because I am concerned that the factory theft-deterrent/immobilizer system did not prevent the vehicle from being started and the alarm did not activate during the unauthorized entry. Acura has not identified the method by which the vehicle was started or provided an explanation for the reported non-activation of the alarm. I am reporting this because I am concerned there may be a vulnerability involving the door-lock, alarm, immobilizer, and other related electronic security systems that could allow unauthorized entry and theft. I am requesting that NHTSA evaluate whether similar incidents have been reported involving 2023 Acura Rdx vehicles or other vehicles manufactured by american Honda motor CO. Including Honda and Acura vehicles.

4 Electrical System problem of the 2020 Acura RDX

Failure Date: 08/28/2026

I am reporting recurring water intrusion into the driver-side passenger compartment of my 2020 Acura Rdx following significant rainfall. This has occurred multiple times. The most recent incident occurred on August 28, 2026, following heavy rainfall. Water entered the vehicle and accumulated on the driver-side floor, leaving the interior floor in a puddle. I documented the water intrusion with photographs and video and submitted that documentation to my automobile insurance company as part of a claim. The vehicle was not being driven through standing water; the intrusion occurred after rainfall while the vehicle was parked. The vehicle has previously been inspected by north park Lincoln of dominion, where I purchased the vehicle. Despite the prior inspection, the vehicle has continued to experience water intrusion into the driver-side cabin following significant rainfall. The recurring water intrusion raises concern that the panoramic sunroof drainage system may not be adequately draining or preventing water from entering the passenger compartment. Water entering the cabin can reach wiring, electrical connectors, control modules, and other electrical components located within the vehicle and could potentially cause electrical malfunction or other unsafe conditions. The most recent water intrusion is documented, and the vehicle and affected components are available for inspection upon request. Photographs and video documenting the August 28, 2026 incident were provided to my automobile insurance company. I am reporting this because the water intrusion has occurred repeatedly and I am concerned that this may represent a recurring safety-related defect with the 2020 Acura Rdx panoramic sunroof drainage/water management system rather than an isolated incident. There were no warning lamps or messages specifically preceding the August 28, 2026 water intrusion. The primary symptom was substantial water accumulation on the driver-side floor following rainfall.

5 Electrical System problem of the 2020 Acura RDX

Failure Date: 08/22/2026

The vehicle’s keyless access/security and body control system malfunctioned. An authorized Acura dealer previously diagnosed water intrusion from blocked panoramic sunroof drains, including water reaching the body control module (bcm) multiplex control unit. The dealer reported that this was causing false security alarm activation and battery drainage and recommended bcm replacement. The vehicle and affected components are available for inspection upon request. The condition has since escalated. The security alarm repeatedly activated without cause and became difficult or impossible to silence. The dashboard displayed, “keyless access system problem\. See your dealer. ” during the latest episode, the engine spontaneously started without an authorized remote start command, and attempts to stop the engine were unsuccessful. The 12-volt battery was therefore disconnected to disable the vehicle and will remain disconnected until the vehicle is taken to the Acura dealership for diagnosis. This created a safety risk because the vehicle demonstrated unintended engine operation and loss of normal control over engine shutdown, creating potential risks of unintended operation, exhaust carbon monoxide exposure if this occurred in an enclosed area, and battery depletion. The dealer has confirmed the water intrusion and bcm security system malfunction. However, the unauthorized engine start and failure to shut down event occurred after that diagnosis and has not yet been evaluated by the dealer. Before the unauthorized start, symptoms included repeated false alarms, battery drainage, documented water intrusion, and the keyless access system warning. The warning was photographed at approximately 81,416 miles during the same period of escalating electrical security problems.

6 Electrical System problem of the 2023 Acura RDX

Failure Date: 08/20/2026

On 8-20-26, my Rdx was stolen while legally parked in front of our home, only 10 days after I traded in my previous 2017 Rdx for this vehicle. I am a repeat Acura Rdx owner, having also previously owned a 2008 Rdx. I did not experience or become aware of this vulnerability on either of those earlier generation vehicles; it appears specific to the current (third) generation Rdx's door/window electrical architecture. The method used to steal the vehicle exploited what appears to be a design vulnerability in the driver's door: the offender(s) forcibly broke/punched through the exterior door handle assembly to gain direct physical access to the internal door wiring harness located behind it. Using that access, they manually activated the power window motor circuit to lower the driver's side window, then reached through the opening to unlock and open the door — completely bypassing the vehicle's locking and anti-theft system. Component that failed: the driver's door window motor control circuit / door control module wiring. The circuit appears to respond to direct voltage/signal applied to the wiring without any authentication, verification of key fob presence, or confirmation that a legitimate occupant is issuing the command. This means physical access to the wiring — obtainable simply by breaking the exterior handle housing — is sufficient to defeat the entire vehicle security system. The vehicle itself is no longer available for inspection in its as-stolen condition, as it was recovered by police in a different location and condition; the damaged handle and wiring may still show evidence of the breach method. Safety risk: this defect allowed an unauthorized individual to gain full entry to and control of the vehicle in under a minute, without needing a key, fob, or any electronic bypass tool, defeating the purpose of the vehicle's locking system entirely. This creates both a theft risk and a broader safety risk, since anyone with knowledge of this meth.

7 Electrical System problem of the 2020 Acura RDX

Failure Date: 08/19/2026

My Rdx experienced a water-intrusion failure involving the panoramic sunroof drainage system and associated electrical components. An authorized Acura dealer diagnosed the right-front sunroof drain as backed up/overflowing, allowing water to reach the body control module (bcm/multiplex control unit). The dealer attributed abnormal security-alarm activation and battery drain to the water-damaged bcm and indicated that the bcm required replacement. The dealer also identified a blocked right-rear sunroof drain that allowed water to reach the tuner, causing radio/stereo malfunction and requiring tuner replacement. The water intrusion reached critical electrical components and caused unpredictable electrical behavior, including unexplained security-alarm activations, exterior lights remaining illuminated, complete battery discharge, loss of keyless access, and ultimately a no-start condition that rendered the vehicle inoperable. After the battery was depleted, I had to use the manual key to enter the vehicle. This created a risk of being stranded and raised concerns about the reliability of the vehicle’s electrical systems. There were no known dashboard warning lamps or conventional warning messages before the failure. Acuralink recorded unexplained security-alarm activations on August 16, 2026, at 10:27 pm edt and again on August 19, 2026, at 10:51 am edt. During the overnight incident, the alarm activated and the exterior lights remained on until the recently replaced battery was completely discharged. The car also experienced radio/stereo problems traced by the dealer to water reaching the tuner, and water was present in the passenger-footwell area. My car was inspected and the problem confirmed by an authorized Acura dealership. The car is available for inspection and available upon request.

8 Electrical System problem of the 2021 Acura RDX

Failure Date: 08/19/2026

Two low-speed sudden unintended acceleration events while parking a 2021 Acura Rdx. Incident 1 (July 2026): while parking at low speed, the car unexpectedly surged forward. Flew up the curb and hit a restaurant window, causing massive undercarriage damage. Active braking did not help and seemed to make acceleration worse. It only stopped when it wanted to. Incident 2 (August 2026): two weeks after getting the car back from repairs, under identical low-speed parking conditions, a second sudden acceleration event occurred. Slamming on the brakes did nothing. It stopped after scraping a car wash vacuum pole, destroying the entire passenger side. Prior to these, the car exhibited erratic safety software behavior, including multiple phantom braking incidents where it slammed on its brakes violently with no obstacles present. I bought the car certified pre-owned two years ago. The dealership repaired a known "popping sound" from the panoramic sunroof frame three times. This required extensive cabin/pillar teardown work, which may have disturbed internal wiring harnesses or grounding points linked to the electronic throttle control system. In both events, it felt like an uncontrolled amusement park ride—the engine loudly revving and taking over with zero driver control. I initially assumed pedal confusion during the first crash, but since it happened again under identical circumstances, there is clearly a systemic electronic/software defect in the throttle actuator or powertrain control module. The vehicle is at an insurance network body shop awaiting forensic evaluation of the throttle system, pedal sensors, and a bosch edr black box download.

9 Electrical System problem of the 2019 Acura RDX

Failure Date: 07/03/2026

The factory-installed led daytime running light (drl) system on my 2019 Acura Rdx has failed. The passenger-side drl is completely inoperative, and an authorized Acura dealership documented that the driver's-side drl is beginning to fail as well. The affected components are available for inspection upon request dealership has declined to provide further documents and american Honda moto daytime running lights are a safety-related exterior lighting system designed to improve vehicle visibility to other motorists. The failure of one drl and the developing failure of the second drl may reduce vehicle visibility and create a potential safety concern. On July 3, 2026, cerritos Acura inspected the vehicle and confirmed the condition. The dealership's written diagnosis states: "recommend passenger headlight assembly due to daytime running light out. Recommend driver's headlight assembly due to daytime running light going out as well. " the dealership recommended replacement of both headlight assemblies. The dealership found no evidence of collision damage, misuse, unauthorized modifications, or water intrusion. The drl is an internal led component that is not serviceable separately and requires replacement of the entire headlight assembly. The vehicle has been inspected by cerritos Acura, an authorized Acura dealership. To my knowledge, the vehicle has not been inspected by police, insurance representatives, or any government agency there is no record of any only with the dealership. There were no warning lights, warning messages, dashboard indicators, or other symptoms before the failure occurred. The drl failure happened without warning and was later confirmed by dealership inspection. I am concerned that the failure of both factory-installed led drl assemblies may indicate a defect in the lighting system rather than normal wear and tear. The condition was confirmed by an authorized Acura dealership and was not attributed to accident damage or other external causes.

10 Electrical System problem of the 2023 Acura RDX

Failure Date: 07/01/2026

Gps has stopped working. This affects navigation safety. Also, creates clock error and compass error. It's dangerous to get lost and disoriented. This is a common problem in many Acuras. Needs to be a recall.

11 Electrical System problem of the 2018 Acura RDX

Failure Date: 06/17/2026

The transmission went into limp mode one day after coming to a stop. When I safely got home, I turned the car off. Upon restarting, the issue was gone, but this has now happened several times. Each time, putting the car into park, shutting it off, and restarting it "resets" whatever was going on. Eventually the ce light came on, got the code, and it came back as p0873. The ce light was off after once again shutting the engine off and then restarting. I've purchased the necessary materials to complete the repair, but I've read on many forums this is a common issue, with some even reporting it recurring even after replacing the pressure switch. Acura should issue a recall and absolve all consumers of costs incurred. Urls provided below from reddit threads and an Acura discussion forum regarding similar issues all over.

12 Electrical System problem of the 2020 Acura RDX

Failure Date: 05/01/2026

I am reporting recurring water intrusion into my 2020 Acura Rdx following significant rainfall. The first water intrusion resulted from heavy rainfall in April 2026. I did not discover the water inside the vehicle until may 1, 2026, when I found water accumulated on the driver-side floor. I filed an insurance claim after discovering the damage. Following the may 1 discovery, gunn Acura, where I purchased the vehicle, inspected it. The dealership found the panoramic sunroof drainage system had a kinked/clogged drain line that was not properly allowing water to drain. The dealership also identified corrosion affecting wiring harness components and recommended repairs including replacement of the moonroof drain tube, carpet removal/cleaning, and replacement of affected wiring harnesses. Following another heavy rainfall on June 15, 2026, water again entered the vehicle. The water intrusion has resulted in electrical concerns, including warning messages and electrical abnormalities. Water entering the cabin can reach wiring, electrical connectors, control modules and other critical electrical components, creating a potential safety risk. The vehicle and affected components are available for inspection upon request. I have dealership documentation of the kinked/clogged drain and recommended repairs, as well as insurance documentation related to the water intrusion. I am reporting this because a failure of the panoramic sunroof drainage system has resulted in repeated cabin water intrusion and potential damage to critical electrical components. I believe this may represent a recurring safety-related defect rather than ordinary water leakage.

13 Electrical System problem of the 2016 Acura RDX

Failure Date: 04/24/2026

On several occasions, the car alarm starts randomly sounding. When my son went to the vehicle, the lights on the dash board were flashing on and off and there was a clicking sound. We replaced the batteries in the key fobs. The battery was low so we had that recharged but the problem continued. We replaced the car battery and that appeared to solve the problem for about 6 months. The same problem occurred again. The only way to stop the alarm from going off is to disconnect the battery. Leaving the door unlocked does not stop this from happening. When we searched online, it is clear this is a common problem with this car, but there have been no recalls or TSB issued. This is a safety issue because we need to disconnect the battery and leave the car unlocked when we leave the vehicle. This has not been inspected by any service center. Based on our research, Acura will recommend replacing the Smart power control unit at a cost of up to $1500 or more. We are hoping that others have reported this as well.

14 Electrical System problem of the 2022 Acura RDX

Failure Date: 04/03/2026

While driving through an active intersection, the vehicle experienced a sudden and complete loss of electrical power. The engine shut off without warning and all electrical systems immediately went dead. The instrument cluster went dark, the ignition was unresponsive, and the hazard lights did not function. The vehicle lost propulsion while in traffic and could not be restarted. Police were required to block traffic to prevent a collision. Emergency responders attempted to jump start the vehicle, but the jump start had no effect. The vehicle showed no signs of electrical power at all. After approximately 15 minutes, while awaiting a tow truck, electrical power returned spontaneously without any repairs or external intervention, and the vehicle was able to start normally. The battery had been replaced approximately one month prior. No other repairs or modifications have been performed on the vehicle. If the battery were discharged, a jump start should have restored power, but it did not. The total electrical blackout and delayed self?recovery suggest an intermittent main power connection failure. This incident resulted in complete loss of motive power, steering assist, brake assist, turn signals, and hazard lights while in traffic, creating a serious safety hazard.

15 Electrical System problem of the 2025 Acura RDX

Failure Date: 04/01/2026

I own a 2025 Acura Rdx with an open eps recall involving potential loss of power steering assist due to improper software calibration. I live in bozeman, montana, far from the nearest Acura dealer. Acura customer care and escalated supervisor offered no reasonable accommodation. Completing this safety recall requires substantial long-distance travel and lease mileage to repair a manufacturer defect. I am submitting this complaint regarding recall remedy access and owner burden.

16 Electrical System problem of the 2013 Acura RDX

Failure Date: 03/26/2026

On 3/26/2026 a symbol of an engine appeared on my dash. Then several minutes later the car began running very rough and numerous warnings signs came on including check engine, check awd system, check power steering system, check uphill assist system and others. I took the car to my mechanic this morning and after checking various systems he determined the cylinder deactivation system was not performing properly. He replaced the spark plug for cylinder 3 and confirmed the ignition coil is functioning properly. He was not able to correct the problem and said I should contact the dealer as he thought Honda had issued an extended recall on the Acura 2013 Rdxs because of this problem. He said this malfunction has caused my awd system to be disabled. I called the dealer and they said there was no recall for this issue. I have an appointment on 3/31 to have them check it out. My car only has 83,635 miles on it.

17 Electrical System problem of the 2019 Acura RDX

Failure Date: 03/15/2026

Vehicle: 2019 Acura Rdx (technology package) I am reporting a serious safety issue involving sudden loss of engine power while driving. On March 14, 2026, I filled my gas tank before traveling approximately 1. 5 hours out of town. The vehicle operated normally that day. The following morning, during snowy and icy conditions, while accelerating in traffic, the vehicle suddenly lost power and stalled. Multiple warning lights illuminated on the dashboard (“christmas tree” effect), and the steering became very stiff, making it difficult to safely maneuver the vehicle out of traffic. I was able to restart the vehicle, but warning lights remained on. The next day, while driving on the highway under normal conditions, the same issue occurred again. While accelerating, the vehicle suddenly lost power and stalled in traffic, creating a dangerous situation. In response, the fuel pump inside the gas tank was replaced; however, the problem persists. The vehicle continues to display warning lights and still loses power when accelerating. I contacted an Acura dealership after seeing reports of a fuel pump recall for similar vehicles, but I was told my VIN was not included. Despite this, the symptoms match known fuel pump-related issues. This defect poses a serious safety risk, especially when driving at highway speeds or in traffic, as sudden loss of power and steering assist can lead to a crash. No injuries have occurred yet, but the issue is ongoing and unresolved. I am requesting investigation into this issue as a potential safety defect.

18 Electrical System problem of the 2017 Acura RDX

Failure Date: 03/03/2026

I was at a stop light, car was stopped, the electronics on the vehicle looked like it went through a reboot, a/c blower fluctuated (turned off then back on), all displays went out and restarted like it does when you start the car. When the traffic light turned green, and I stepped on the gas, the car shuddered and hesitated, like the transmission, abs and traction control were all going haywire. Then the car drove fine. As long as I do not slow down too much or stop. Once I got home and had to back up into the garage, it went through that haywire cycle again. This was the 3rd time this has happened on this car. But after I shut off the engine, wait a little while and start it again, symptom seems to go away, until it decides to happen again. I have had this car since July of 2024, and since that time, I have had this happen to me 3 times and 2 times to my wife. I have read on the net and one of the possibilities talked about if the abs control unit, where soldered wires seems to be melting off of the circuit boards and causing intermittent connection, therefore exhibiting erratic behavior. There are even services on ebay where you can send in your whole abs unit and they will open them up, clean and re-solder the wires. This seems to be scary and concerning from a safety perspective. Please investigate the issue for us who are affected. Occurrences are getting more frequent (almost every other day) and it just happened again today 3/3/26.

19 Electrical System problem of the 2019 Acura RDX

Failure Date: 02/27/2026

Component failure & inspection: the rear windshield glass spontaneously imploded/shattered. This is a documented manufacturing defect involving the rear defroster grid, as detailed in Acura technical service bulletin (TSB) 22-014. The vehicle and the shattered glass are currently available for inspection. Safety risk: the glass shattered while the vehicle was occupied, spraying shards of tempered glass into the cabin. This posed an immediate risk of laceration and eye injury to the occupants, as well as a significant distraction/startle hazard that could have resulted in a collision if the vehicle were in motion. Confirmation: the failure was inspected and confirmed by mcgrath Acura of westmont on February 27, 2026. The dealership acknowledged the existence of TSB 22-014 and the defect in the defroster grid but has not yet provided a full remedy. Manufacturer inspection: the vehicle is an Acura precision certified unit. A formal case has been opened with Acura client relations (case #16209033), and photos of the failure have been provided to them. Warning symptoms: there were no warning lamps or symptoms prior to the failure. The glass imploded suddenly and without external impact while the vehicle was stationary.

20 Electrical System problem of the 2015 Acura RDX

Failure Date: 01/16/2026

Common problem with this year and model is the low beam projector headlight assembly dims. This is a huge hazard and makes it impossible to see at night with low beam lights. I cannot see more than 30 feet in front of the vehicle at night making the reaction time to any potential threat non-existent at freeway speed and severely reduced in neighborhoods. All options investigated are to replace assembly, not lightbulb. This is a manufacturer fault and cost should be bourn by the manufacturer. Same problem with the rlx and Acura voluntarily recalled those headlights for replacement. They should be required to do the same for these.

21 Electrical System problem of the 2018 Acura RDX

Failure Date: 12/18/2025

My car's original security alarm goes off randomly without any reason. When parked and locked in a parking lot next to a street, the alarm goes off intermittently. After unlocking using fob, the alarm will turn off and then goes off again in a few minutes. This will go on for hours at a time until it stops for a few days and then reoccurs again! very stressful and frustrating. The mechanic says it's caused by faulty body control module and will cost over $1,000 to fix. I see that many people are having the same issue and have to pay over $1,000 to repair. This faulty reequipment should be recalled so owners can recoup their damage.

22 Electrical System problem of the 2019 Acura RDX

Failure Date: 12/16/2025

Vehicle was stolen within 15 minutes due to a weak door lock cylinder on the driver's door. Once the robber was inside they used a scanner yo bypass the weak security system and erased all key fobs.

23 Electrical System problem of the 2019 Acura RDX

Failure Date: 12/15/2025

I am writing to report an incident involving the rear window of my2019 Acura Rdx that shattered unexpectedly. The incident occurred while the vehicle was parked at my workplace. I was notified by a CO-worker that the rear window had shattered. Upon inspection, there was no obvious sign of a collision, vandalism, or other event that would explain the damage. A glass replacement company was called to my workplace to replace the shattered rear window. After examining the vehicle, the technician advised that there was no evidence of an external impact, such as a rock strike or other object, that would have caused the glass to break. Because the window appeared to shatter without any apparent outside force, I am concerned that this may indicate a defect in the rear glass or its installation. I respectfully request that this incident be documented and reviewed as a potential safety-related issue. Thank you for your attention to this matter.

24 Electrical System problem of the 2019 Acura RDX

Failure Date: 11/26/2025

The center infotainment display went completely black, with only the backup camera feed still functioning. There was no audio output at all (radio, navigation prompts, or bluetooth). The dealer diagnosed and replaced the fakra service cables under Acura TSB b23-025, which addresses this exact display-blank/audio failure. After the cable repair, the screen remained black and audio remained completely non-functional. The dealer then determined the tuner/av control unit had failed, confirmed by swapping in a working unit from another Rdx which restored function. Acura client relations was contacted and declined to provide any coverage for the tuner unit replacement, stating the TSB only covers the cables themselves, despite the failure occurring immediately downstream of the covered repair. The vehicle is safe to drive but loses infotainment display, audio, navigation, and rear camera guidelines during forward driving, which is a distraction and safety concern. The vehicle remains available for inspection. No warning lamps preceded the failure; the screen simply went black. ".

Failure Date: 09/28/2025

While driving in the rain, after an hour long drive home from philadelphia back to reading, taking [xxx] and [xxx], I accelerated my vehicle while going around 50 mph and immediately was faced with a blinking check engine light and lost the ability to accelerate. My Acura essentially went into, what others call, limp mode while in sport mode. I filled my car with 93 gas around 20 minutes before this. After losing acceleration, I pulled over on the highway and the check engine light disappeared. After which, I still was unable to accelerate after leaving the car in park. After I turned the car off and turned the car back on maybe 30 seconds later, I was then able to accelerate and found no issues afterwards. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

31 Electrical System problem of the 2025 Acura RDX

Failure Date: 07/27/2025

While driving at highway speed, all of a sudden I lost all power steering and multiple system failure warning lights appeared on the center dashboard including power steering failure, brake system failure and collision mitigation system failure, among others. With great difficulty I was able to steer the car off the highway and was towed to an Acura dealer. The car was 5 months old with just over 3000 miles at the time and there were no prior issues and no advanced warning when this happened. The dealer (Acura of berlin in CT) stated they have seen this issues several times. The battery voltage was low (11. 98-12. 09 volts), although the car was being driven at highway speeds for at least 45 minutes before the incident. They charged and tested the battery, and their diagnostics said the battery was good. They also found a code "dtc u3000-49 eps control unit internal circuit malfunction". The dealer opened an incident with the Acura tech line, who indicated that if the problem happens again they should replace the steering rack. No repair other than battery charging was performed. This is an unacceptable safety risk waiting for it to happen again. There are many reports of this exact problem online from 2025 Acura Rdx owners. We need an immediate recall.

My car alarm starting going off at random throughout the night, last night and day today. The car also started flickering all the dashboard lights while the car was turned off completely. This seems like it’s the keyless access unit. I don’t know how the battery is not dead yet but seems like it will be tomorrow. The car has not been diagnosed by a dealership or independent service center but I’m seeing many people say they’ve had this same issue happen to them with the same year, make and model. There was no warning lights or symptoms instead I was woke up in the middle of the night to my car alarm going off. After turning the alarm off it happened again after about 5 minutes. My neighbor was outside and told me that it had actually been going off all night. I am now the villain of the neighborhood. This will definitely kill my battery as I’m watching and hearing electrical components turning on when I haven’t touched the key fob or door.

The contact owns a 2025 Acura Rdx. The contact stated that while driving approximately 30-35 mph and exiting the interstate, the power steering became inoperable. The steering wheel was difficult to turn. The power steering, low brake speed, and lane keep assist warning lights were illuminated. The message “do not drive vehicle – see dealer” was displayed. The driver pulled over safely. The vehicle was restarted, and the contact continued driving. The vehicle was towed to the local dealer, who was unable to determine the cause of the failure; because there were no warning lights illuminated upon arrival. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The failure mileage was approximately 2,000.

34 Electrical System problem of the 2021 Acura RDX

Failure Date: 06/12/2025

Acuralink app was used to attempt to remote start car while at a store, however, the app reported a failed notification and car was never started through the app and only turned on manually. Two hours later, when at home, the car remote started suddenly with no prompt while it was inside of a closed garage. Our dog heard the car go off and alerted us. Had he not heard it, the car would have been running in a closed garage putting us at risk for carbon monoxide poisoning. I have done no other reporting, but I did look this up and found threads online about the same issue and was recommended to report here. There were no other warnings or messages to say that the car turned on.
