Engine And Engine Cooling Problems of Acura RDX - part 2

On October 31, 2024, I was nearing the end of a three hour trip. I was traveling on a rural two-lane highway with a 55 mph speed limit. I had just pulled away from a 4-way stop intersection and was following a single vehicle traveling 40 mph. Once I could see there was a safe distance from oncoming traffic, I decided to pass the slower vehicle. As I moved into the opposite lane and accelerated, the engine lost power and barely made it around the car I was passing. If oncoming traffic had been closer there could have been a head-on collision. The engine light started flashing and I had to keep the accelerator pressed half way to the floor to maintain 50 mph. There was no shoulder on the road and no place to pull over, so I continued for 15 minutes with engine light blinking and struggling to maintain 50 mph. No other warning lights came on and the engine was not overheating. When I reached my destination I turned the engine off and then restarted it. The flashing engine light was gone and the car drove fine. The nearest Acura dealer was an hour away so I took the car to my dealer when I returned from my trip. They test drove the vehicle and called the Acura tech line. They could not duplicate the problem. They said they did not find any diagnostic codes so there was nothing they could do. They said if it happens again to bring it back. If it happens again I might not live to tell the story!.

Engine judders at 2k rpm around 60 mph. Car has 92k miles with timely documented service maintenance. Took car to the dealership and said there’s a head gasket leak on cylinder 4 and needs to be replaced. Contacted american Honda about the issue and they said they cannot cover the repair cost. They also don’t have the replacement part for the fuel pump recall for a long time as well.

My 2018 Rdx has started to jerk when I stop and then restart. I have noticed some hesitation and a bit of jerky driving but today it was very noticeable. I could barely go above 40 miles an hour after I started driving after a stop light and the car was very jerky. It seems to be either a fuel pump or transmission issue. I am going to check with the Rdx dealership where I bought the car in 2018 but I wanted to report the issue. I also looked up the VIN on my car for a recall and the system said my car had not been recalled. Not sure why my 2018 Rdx is different from other 2018 Rdx models that were recalled.

Highlight: the car was able to be started with a button press and driven away without any key inside the car. (also, some side information that the car had it's annual check-up on the Saturday before this incident). Normally my wife keeps her purse in the house on the counter (along with the spare key in a drawer under that counter). Previously, if she forgot her purse (and car keys inside the purse), she would head out to the garage and attempt to start the car (she keeps it unlocked in the garage). In a normal situation, the car would beep at her that she didn't have the key and she would go into the house to grab her purse. On 7/31, after a frazzling day, she got a call from her doctor to come to their office for a checkup (40 minutes away). She forgot her purse again; however, this time, the car started without any warning. She took the complete drive to the doctor's office shut off the car and then realized she didn't have her purse. She even tried to turn the car back on to see if the key was in the car, it did not start. She called me, I checked her purse and spare key were both in the same location they were always in. I did remotely try to start the car to see if she could drive it back with me starting it, however, it wouldn't let her take it out of park. She continued with her doctor's appointment. Inconveniently, I grabbed her purse and took my car 40 minutes to drop off her keys and back. Luckily, she was at a doctor's office and in a safe space, however, this has the potential to be very inconvenient and unsafe for others.

My vehicle stopped in the middle of the road as I took exit from the highway. I was almost rear ended as I was entering the parking lot . The vehicle just stalled. I took it the Acura dealership for fix and they have not taken care of recall issue. I am being asked to spend money on fixing other electrical errors first before they fix the recall on my vehicle.

Interstate 10 near live oak, florida. Conditions were light fog and roads were dry. The previous day we drove about six hours, two or three times in very heavy rain. We were driving eastbound (two eastbound lanes) in the right lane. We were approaching a semi-trailer followed by a medium-sized box truck and switched to the left lane to pass both vehicles. Another vehicle was approaching from behind in the left lane and I "floored" the accelerator pedal to quickly pass the two trucks. The Rdx downshifted as expected and the engine revs increased briefly, but suddenly the check engine light started blinking and the car lost power and went into limp mode. Pressing the accelerator to the floor made little difference. Instead of quickly passing I was only able to get past the two trucks at a slow rate with a line of vehicles growing behind me. Eventually I was able to get past the trucks, switch lanes and quickly move over to the breakdown lane. If there had been heavier traffic, this could have easily resulted in a serious accident. I restarted the vehicle and resumed our trip without further incident. This is a known issue supposedly addressed by Acura via TSB 20-053 for some model years and reported on Acura enthusiast web sites. I had the same experience with my previous 2020 Rdx after having the TSB completed, I filed an report for that incident under NHTSA id number: 11522688. There are hundreds of reports for this issue for all 3rd generation Rdx model years, 2019-2024, on the NHTSA site I brought the vehicle to a dealer on July 5, 2024. Unable to duplicate. No codes stored (as has been stated on other reported incidents). No water intrusion to coil packs or plugs and no fouling or damage to plugs. I cannot trust a vehicle if I have to be concerned about whether or not I should pass another vehicle and how hard I can press the accelerator. This is an ongoing issue with the Rdx that should be investigated.

Drove into parking lot and as I was pulling into the parking spot next to the building, the vehicle started to surge forward as if I had my foot on the gas instead of the brake. The sudden surge caused the vehicle to plow into a brick building causing about $10k damage to the vehicle and $5k to the building. This was not the first time this sudden surging occurred. It happened at least 3 times previously, and one time since. Fortunately, the other occurrences did not lead to any damages, but just some anxious moments. I took the vehicle to the dealership to get checked out after the last occurrence, but they said they couldn't duplicate it. I thought it might be some sort of "unknown" problem, until I started reading on facebook and other internet websites of other people having the same scary "surging" engine issues. I believe there's more to it now, and an investigation is warranted.

The contact owns a 2018 Acura Rdx. The contact stated while driving 80 mph, the vehicle lost motive power and decelerated to 0 mph. The contact was able to pull over safely. The vehicle was restarted and worked as designed. The check engine and emissions warning lights were illuminated. The contact received notification of NHTSA campaign number: 23v858000 (fuel system, gasoline) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was approximately 140,000. Parts distribution disconnect.

Vehicle began jerking while in motion, and all error messages the vehicle has ability to display rotated across the screen, including po848. Transmission was replaced by a dealer. Vehicle would not start two weeks later. Vehicle towed to dealer. Dealer stated battery and starter were bad. Both of those components replaced by Acura dealer. Within one week, alarm was sounding randomly and clicking noise coming from dash. Dealer is now replacing a control module. This is a safety issue because as it was jerking, I lost control of the vehicle. The car alarm going off for a prolonged time at high decibels puts the hearing of bystanders at risk. Seems the car poses a fire risk as well.

While driving on a freeway for about 15 minutes at 65 mph, the mil indicator started blinking. The vehicle began to rapidly shake, while the engine power decreased significantly. The engine dramatically went from 65 mph to 35 mph causing a safety hazard while driving on the freeway as we attempted to exit and pull over safely. The vehicle is a 2021 Acura Rdx and is driven approximately 10,000 miles per year. All maintenance has been performed in accordance with the manufacturer's schedule. It has not been involved in any collisions or other user risk other than normal driving in accordance with the approved use of the vehicles. Upon trying to restart the vehicle, the vehicle continues to violently shake while in park. Notification lights indicating brake failure, awd failure, check emissions system, etc. There were no other indicators that there was an issue with the vehicle prior to this instance on 4/20/2024. In fact, the vehicle was viewed by cerritos Acura for its regularly schedule service on 4/10/2024 and no issues were identified by the dealer. As far as safety, we were traveling with two young children and the location of the freeway did not have a safe place to pull over. The sudden reduction in speed also put us in risk with surrounding vehicles. This appears to be related to TSB 20-053, however, no communication have been identified or communicated by the dealers to the the owner/operator of the vehicle.

The emission light flashes and puts the vehicle in "limp mode. " the speed is drastically reduced and won't exceed 30 mph. Horrify experience. The problem seems related to rain and acceleration. Now the car is towed. No warning before it happens. But the emission light was flashing afterward.

I am writing to report a concerning issue with my Acura Rdx 2017, which I believe poses a significant safety risk and requires immediate attention from your organization. The problem I encountered while driving jeopardizes the safety of both myself and others on the road. About five days ago, while driving at approximately 20 mph, my vehicle began emitting loud, thunderous sounds, accompanied by intense vibrations that shook the entire car. Additionally, it seemed to struggle when shifting gears, particularly into second or third gear. Despite my careful and gradual acceleration, the car exhibited signs of a malfunction within its transmission system. Furthermore, at around 35 mph, the engine suddenly revved to over 3000 rpm, causing the vehicle to accelerate without any input from me. This acceleration occurred even though my foot was not on the gas pedal, making the car difficult to control and putting me at risk of colliding with other vehicles or objects. The unpredictability of these incidents is deeply alarming and could lead to serious accidents if not addressed promptly. I purchased this vehicle in December 2023 and have maintained it according to the manufacturer's recommendations. However, when I inquired about the timing belt at the dealership, I was assured that it had passed inspection. Despite this, the recent malfunctions suggest a more serious underlying issue that needs immediate attention. Crucially, there were no warning lights, messages, or other indications of a problem prior to these incidents, underscoring the sudden and unexpected nature of the issue. I urge the NHTSA to investigate this matter urgently and thoroughly. I request that you initiate a recall of affected vehicles and implement necessary repairs to address the identified defects. Swift action is essential to ensure the safety of all motorists who may be affected by this issue.

On entering the highway and accelerating quickly, engine lost power and car entered limp mode, refusing to exceed 60 mph. Also, check engine light began flashing. Very dangerous situation in heavy traffic all going over 70 mph. Exited at next exit, shut down car, then restarted with no further issues.

On a long road trip (2/11/2024-2/19/2024) from milwaukee, WI to bowling green, ky. And from from bowling green, ky to orlando, FL. While driving from bowling green, ky about 8 hours into the drive, we were in a massive rain storm which started in atlanta, GA. And did not end until we crossed into florida. About 60 miles past the border of florida traveling on i75, I needed to over-ride the cruise control traveling at about 80 mph and allow for a merging vehicle, so I pressed hard on the accelerator and the vehicle essentially shut off and the mil was flashing. I was in the left lane (two lane highway at this point) traffic was moving quickly, but fortunately I was able to merge safely across traffic to the right shoulder without causing an accident because the vehicle was slowing at a rapid rate. The vehicle came to a stop on the shoulder with my wife and two kids freaking out. I shut off the vehicle, successfully restarted the vehicle and accelerated into traffic. Fortunately this did not happen in the mountain pass where there is no shoulder to pull into.

I was passing another vehicle around 45mph when I had a loss of power in acceleration. Acceleration was limp went down to 10mph engine light came on. I had to pull off road. Shut car off then restarted. Engine light went off. But acceleration is weak. Unable to maneuver away from an emergency situation if need to. Dangerous to drive it like this. I will take it to dealership but know they' never find any issues!.

On 2-10-2024 I was driving the 2021 Rdx sh-awd on I-40w in TN with my daughter in the passenger's seat. It was raining. After about 2 hours of driving, at about 3:00 pm, I took a break at a rest area near buffalo valley. After ~20-min rest, I restarted the car and tried to merge back onto I-40w. I was accelerating towards the speed limit of 70 m/h, but suddenly, at about 65m/h, I felt the car losing power. I could not speed up anymore: the car did not respond to the gas pedal and the speed dropped to about 40m/h. The orange engine light started to flash on the dashboard. A truck nearly piled on me from behind. Cars and trucks from behind had to switch lanes quickly to avoid collision. I was able to pull over to the shoulder and stopped with my emergency light on. I turned off the engine for about 10 minutes, then I restarted the car again and got back on the road. This time, everything seemed normal, but I was so scared and worried the car might suddenly not respond again. Fortunately, I was able to get home eventually without any additional problems.

Near the first of the year 2024 I received a fuel pump recall notice for my 2019 Acura Rdx. To date, no parts for addressing this issue have been available and no timeline has been made available as to when parts would be available. I am planning my annual trip to the eastern sierra in early September where no Acura dealer is available nearby. Should the fuel pump fail during that trip it would be a significant inconvenience for me, including interruption of medical appointments, room and board expenses, pet sitting expenses, etc. , as I have been told by Honda that in such an emergency situation the car would have to be towed to the nearest dealership, with the part being specially ordered which would take 2 weeks and that I may be responsible for my room and board, and other costs during that period. I find this behavior to be outrageous. Additionally I have been told by my local dealer that it is not possible to determine possible failure beforehand as either it is working or it has failed. This is totally opposite from what I was told by Honda which was to schedule an appointment with a dealer to determine the status of the fuel pump so that they could special order one for replacement if it demonstrated potential failure. This entire issue reeks of poor and ineffective management of this situation by Honda, likely putting costs over safety putting me at substantial risk for this trip that was planned a year ago and likely will cost me my deposit and access privileges if canceled. As such, I am requesting that NHTSA hold Honda/Acura accountable for this disgraceful behavior, putting owners of their vehicles at substantial risk, and demand that they explore and take immediate actions to resolve the parts shortage in a reasonable amount of time.

Safety concerns with 2015 Acura Rdx engine. My vehicle has experienced multiple serious engine failures beginning December 8, 2023, when it suddenly lost power while driving with a flashing check engine light. Despite multiple repair attempts by mcdaniel's Acura dealership (timing belt replacement, spark plugs, front cylinder head replacement, pulley replacements), the issues have persisted and worsened. Technicians found oil in cylinders 1&3, metal debris in the oil filter, and diagnosed the engine as failing in may 2024. Current symptoms include white smoke from the tailpipe, engine rattling, and ongoing risk of sudden failure. This vehicle was leased new in 2015, purchased after lease term, and consistently maintained at Acura dealerships. Despite opening two cases with Acura client relations (#14622769 on April 29 and #14633862 on may 6, 2024), Honda financial declined assistance. The dealership only offered a trade-in "incentive" while admitting they couldn't resell my vehicle due to its condition, and would instead auction in off. I'm unable to safely use this as my primary transportation. Similar engines have had multiple recalls between 2018-2023, including a December 2023 recall of 2. 6 million vehicles for fuel pump issues and recalls for connecting rod bearings in similar engines. In November 2024, NHTSA began investigating 1. 4 million Honda/Acura v6 engines for rod bearing failures. I request NHTSA investigate whether this represents a broader safety defect affecting other Acura Rdx vehicles. Service records from December 2023-may 2024 are attached as documentation of all repair attempts and diagnoses by authorized Acura technicians.

I was driving on the highway and it was raining. I tried to pass another car so I started to accelerate. But during my attempt to accelerate, my 2019 Acura Rdx would not respond to throttle response. So I slowly started to loose speed the car. The engine warning light started to flash and the car came to a stop on a dangerous road construction area with no medians. I had to turn on my hazards and wait on the road at night. I quickly turned off the engine and tried to turn the engine on again. When I turned the engine on it no error codes were shown and the check engine light was gone. I started to drive again and was able to get to a service road. After a while I decided to try to keep driving so I could get home and when I was merging into the highway, it happened again. The same situation, I was accelerating when my engine decided to stop accelerating and flash the check engine light (it didn’t stall but it wouldn’t respond to throttle response). I stopped on the side of the road and turned the engine off before turning it on again. Again the check engine light was not on, and the car acted like nothing happened. It seems like accelerating to higher speed in the rain is a huge safety issue….

Fast blinking engine light, and car not able to accelerate past 40mph. Was informed by dealership that it was possible water intrusion but had no guarantee or adequate mitigation strategy to ensure the problem would not occur other than indicating it is normal behavior to expect during heavy down pour!! the following codes were presented to dealership service dept after performing diagnostic: p0300, p0301, p0304 car has 10k miles and it’s a 2023 Rdx a spec. Another issue happening with the car is an intermittent “brake failure. See dealership” message on the dashboard. Was told it’s expected behavior for this to sometimes happen and due to no permanent code present, they cannot repair or identify the issue. I guess the breaks have to fail while driving before they actually prevent an accident from happening?!!!.

My car has been shaking on acceleration but no engine light or any warning popped up. When I called an Acura dealership, they said they would have trouble diagnosing the problem without a light on. A few days later, while accelerating on the highway, my car started shaking violently and lost power. The engine light started flashing. I could have gotten into an accident because I could no longer accelerate on the highway. I had to slowly pull off to a safe stop. This could have been a dangerous and life-threatening situation. Someone could have crashed into me behind me and I could not quickly get into a safe area. I brought it to an Acura dealership and they could not find anything. The engine light had turned off. Though, when I took the car again, the car was still shaking on acceleration. I was afraid to drive at normal speeds since it is extremely safe. I took it to another personal mechanic and he was able to reproduce the problem. He saw there is a service bulletin out for just this problem. The possible cause is “humid air within the intake tract may condense and accumulate excessive moisture during steady driving. ” I would have to replace the intercooler system and get the pgm-FL software updated. This is a safety issue, and Acura has not released any recalls on this. The dealerships are also saying it will not be covered by warranty for me.

Vehicle began hesitating when starting, but not all of the time. One day after refueling it would not start. Lights on the dashboard flashed and flickered and the keyless start button made a clicking sound, but the vehicle would not start. Vehicle was towed to the nearest mechanic. The next morning the mechanic started the vehicle and found nothing wrong. Mechanic kept the vehicle for a couple days and the problem reoccurred. Vehicle will not start. Computer diagnostics shows the 2018 Acura Rdx control unit part number 38320-tx4-a31 is faulty. This part is backordered and likely will not be available in the near future. The intermittent starting failure poses a safety risk and could leave a driver stranded.

The contact owns a 2014 Acura Rdx. The contact stated while driving approximately 70 mph, several unknown warning lights illuminated, and the vehicle lost motive power and stalled. The contact stated that moments later the vehicle re-started independently and the operated normally. The vehicle was taken to the local mechanic who was unable to determine the cause of the failure. The contact stated that the failure recurred; however, the vehicle failed to restart. The vehicle was towed to the residence. During the failure, the contact stated that the "charging system" warning light continued to flash off and on. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The failure mileage was 98,000.

We experienced loss of power in heavy interstate traffic. We had been driving in the rain for some time on I-10 in florida. We were in the right lane behind a vehicle that was traveling much slower than other vehicles. There was a gap in vehicles in the left lane so I signaled and pressed the gas pedal significantly so I could quickly get up to a matching speed for the left-lane vehicles. At this point the engine stumbled a couple of times and the check engine light began flashing. No matter how hard I pressed the gas pedal, my vehicle would not accelerate. Cars behind us had to brake quickly to avoid hitting us from behind. I turned on my emergency flashers and made my way to the right-side breakdown lane. After stopping, I turned our vehicle off and restarted the engine. No warning lights were lit and I was able to resume our drive. This is a known issue with our vehicle and other Acura/Honda vehicles. There is an existing Acura technical service bulletin (TSB), 20-053, that addresses this issue. This TSB was applied to my vehicle in March of 2021. Apparently, the TSB has not resolved the issue. This is a serious safety issue. At the very least, the car behind us could have hit us and this could have caused a multi-vehicle accident. If a semi had been behind us and couldn't stop quickly, we could have been killed. In online discussions there are a number of people that have experienced this issue. This is not an isolated incident and should be investigated.

The contact owns a 2019 Acura Rdx. The contact stated that while driving approximately 65 mph, the check engine warning light suddenly illuminated, and the vehicle lost motive power and started to decelerate. After pulling off the roadway and restarting the vehicle, the failure was self-corrected, and the vehicle operated as designed. The cause of the failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 57,000.

Driving about 75 (local speed limit) from college station texas to plano, texas over the easter weekend and vehicle suddenly lost all power, check engine light illuminates, and I have to pull over. After several minutes, light is extinguished. Restarted vehicle and service engine light illuminates (b17). Had not been on before. I drove about 65 the remainder of the trip and took it to the dealership in town. The incident can not be replicated per the shop. 22k miles.

While sitting in a long row of stopped vehicles at a traffic light for an extended amount of time due to an accident I had the automatic brake hold feature activated { I did not have to have my foot on the brake while sitting still) as well as the auto idle stop off button meaning {the engine shuts down when you come to a stop. } apparently, the brake hold feature timed out with no warning whatsoever and because the vehicle moved forward the auto start stop feature activated at the same time and the vehicle lurched forward rear ending a new expensive SUV in front of me. The impact was hard due to the quick lurch of my vehicle. I have damage to the front of my vehicle and all of the electronic features started flashing including the emission control. The driver advised she was very shaken up and if a pedestrian or bicyclist had been in front of us it could have been very tragic. The vehicle is being towed to a local Acura dealer for evaluation and I have a case number assigned by Honda with no case manager assigned yet. There were no warning lights/lamps at all prior to the vehicle brake hold timing out and further searching through the manual only says it times out after 10 minutes but does not advise what happens when that happens or what warning will be used.

Once again, 3 weeks after the first time it happened, my 2019 Acura Rdx lost all power and I had to drift to the side of the road. This occurred on the baldwin beach express and luckily there is not a lot of traffic this time of year so I could get on the shoulder. Car would not restart, all lights around the speedometer had come on. I had to have it towed to the Acura dealership in mobile where it was towed the first time when this happened. At that time the told me they could not duplicate the problem. Three weeks later it has happened again . The tow truck driver tried to start the car and said " you're not getting any fuel" and asked if the fuel pump had been checked. Supposedly it has been replaced when it was first recalled. Could it be another faulty fuel pump? my question. . . . How dangerous would this be if this happened in the I-10 mobile tunnel?????? the first time it happened I tried to call Acura but the complaint department is not open on sundays. This time it happened on a Friday and I was able to file my complaint. Will I get a response to this event now that it has happened a second time?.

While driving on interstate 65 headed towards mobile, al. My 2019 Acura Rdx lost all power. Every light surrounding the speedometer was lighted. No power, nothing. . Was able to coast from the right hand lane to the shoulder of the interstate. . No power steering and I was moving slower and slower because I was on a hill. Frightening to say the least. If I had been in the left hand lane I’m not sure I could have made it to the shoulder. And if a truck had been behind me an unable to change lanes I would have been smashed. Car towed to dealership.

On 12/22/22, I was driving in a 2021 Rdx sh-awd with my pregnant wife and 2 year old son from media PA to pittsburgh PA . It was rainy and 35-40 degrees f the whole drive. Approximately 4 hours into the drive we stopped at a rest stop on the PA turnpike to get gas. While attempting to merge back onto the turnpike from the service road to the right of the turnpike, a truck was coming up behind me in the right hand lane of the turnpike. I was traveling approximately 40mph on the service road, so I went to accelerate to safely complete the merge in front of the truck. Near the end of my acceleration sequence (I estimate I had gotten to approx 65mph) my car went into “limp mode”. I felt an unexpected and immediate loss of power and my check engine light/“mil” began flashing yellow. I was luckily able to barely avoid a collision with the truck that was approaching. After the light started flashing I was unable to turn the knob to switch drive modes (it was in snow mode at the time this all happened). I was unable to do anything but attempt to drive to safety with severe power loss. I was able to coast my car with minimal accelerator response to the next exit off the turnpike and into a motel parking lot. I shut down the car and then turned it back on. When I turned it back on, the mil light was no longer flashing and I had normal power restored to the vehicle, but interestingly the auto stop/start feature no longer worked. I was able to drive the remainder of the way to pittsburgh without any further loss in power, though I was anxious the entire drive considering the major malfunction I had just experienced while attempting a merge at highway speeds. The vehicle only had approx 10,500 miles on it at the time of the incident. The vehicle is currently at the dealership being diagnosed. A case has also been opened directly with Acura/Honda.

The contact owns a 2022 Acura Rdx. The contact stated while driving 60 mph and depressing the accelerator pedal, the vehicle failed to accelerate. The contact stated that the check engine warning light was illuminated. The contact stated that the vehicle decelerated to 30 mph and failed to accelerate while depressing the accelerator pedal. The contact exited the highway and parked in a nearby parking lot for approximately 10 minutes. The contact was able to continue driving to her destination. The contact took the vehicle to the local dealer however, the mechanic was unable to duplicate the failure. The manufacturer had not been informed of the failure. The failure mileage was approximately 900.

I have a 2021 Rdx. Was on the interstate moving at about 70 mph coming back from missouri. Raining. Lots of semis creating huge following misty, hard to see rain. Decided to accelerate to pass a couple. Car nearly stalled and acted like it had lost a cylinder's worth of power. Turned on hazards, slowed, pulled over and lifted the hood hearing all kinds of unusual noises. Shut the car off and restarted. All was well. Turned all lane-keeping, etc. Off including cruise. Drove the last 100 miles or so without incident. Called dealer and was told likely didn't pull a code. Don't worry and keep driving. Said to make sure front of car was clean. Duh!! I keep my ride spotless (unless driving in the rain). Called CA's Acura line. Absolutely no help. 2 different females had no idea what limp mode was. Read quite a bit since then finding out it could be the result of many things including problems that could damage the motor and/or tranny. Wow!!! had never heard of "limp mode" before. Nice that no info on this possible problem was anywhere in any user manual. Car has performed flawlessly ever since. So far, I guess the rain had interfered with the "radar" system and confused the computer. I'm thinking about buying a 40 year old car that doesn't have any of the modern computers etc. Later found info regarding TSB 20-053 which explains the problem and proposed solution. 06-26-2022 06:52 pm.

On 9/22/22 travelling on I-290 near boylston, MA I was passing a large tractor trailer in the far left lane going up a hill. It was and had been raining very hard for at least the previous hour. When I stepped on the accelerator to increase speed, the car suddenly decelerated to about 20 mph and the check engine light began flashing. I was able cross all three lanes in very heavy traffic to the shoulder. I then slowly made my way off the interstate to a gas station right beyond the exit. My passengers and I were very concerned about the suddenness and the abrupt reduction in speed on an extremely busy roadway. A call to the nearest Acura dealer service department confirmed he had seen nearly the same symptoms the prior week under similar road conditions and the same model car as mine. He found no codes on the other car. I also notified Acura customer service who confirmed the existence of a service bulletin on precisely this issue (flashing light with loss of power).

On September 6, 2022, at 7:45 am I was traveling from my home to work in my 2020 Acura Rdx. As I was merging on to an interstate in heavy, high-speed traffic, my Rdx suddenly lost power and started to decelerate with absolutely no warning at all as high-speed traffic was approaching from behind. My vehicle decelerated to a speed of about 20mph on an interstate in the midst of heavy, high-speed traffic. The malfunction indication light began flashing in the instrument panel. I was able to drive at slow speed of about 15-20 mph, with 4-way lights flashing, until I could exit the interstate. I turned the car off for a few minutes and then was able to proceed. This created an extremely dangerous situation.
