Electrical System Problems of Lexus RX - part 1

While driving my 2026 Lexus Rx350h, the vehicle suddenly lost propulsion and would not respond to the accelerator. After coming to a stop, pressing the gas pedal did nothing. I had to shift to park, press the brake, and press the start button to get the vehicle moving again. A short time later, while making a right turn, the vehicle lost power again while still moving, forcing me to repeat the park–brake–start sequence in the middle of the turn. This is a serious safety issue because the hybrid system appears to shut down unexpectedly, causing loss of propulsion in traffic. The vehicle was towed to the dealer, who stated the battery was “good,” but no cause was identified. This needs investigation because the vehicle can unexpectedly lose power and require a restart while driving.

The power tailgait opens but wont close, gives two beeps.

Electronic parking brake (epb), 12v battery/electrical system. My vehicle's 12v battery failed, with the dealership measuring voltage below 10v during the event. This caused multiple simultaneous module malfunctions (confirmed by the dealer as caused by the battery failure), including a complete inability to move the vehicle after jump-starting on three separate attempts — the engine ran, but the vehicle would not drive despite a functioning alternator. The vehicle's steering wheel also locked, preventing the car from being pushed to a safe location. Approximately 3 months after this event, a routine service visit revealed the rear brake pads had worn from 8mm (measured at time of purchase) to 2mm (failed), while the front pads wore from 10mm to 7. 8mm (normal wear) over the same period and mileage. The rear pads wore roughly 3 times faster than the front, which is inconsistent with normal vehicle operation, since front brakes handle proportionally more braking load and are fitted with larger rotors for this reason on this and virtually all vehicles. The rear brake caliper is the only caliper equipped with the epb motor/actuator; the front calipers are purely hydraulic. The selling dealer's pre-purchase report also noted noise from the rear brakes at time of purchase, which is consistent with the epb's position calibration having been disrupted at some point prior to my ownership (e. G. , from a prior battery event or service) and never properly relearned/recalibrated afterward — producing a low-level drag from the outset. My own battery failure event (voltage measured below 10v) would then have compounded this already-uncalibrated system, worsening the drag and producing the rapid 6mm of wear observed in the following months. This points to one underlying epb calibration fault, aggravated by repeated voltage instability over time, rather than an unrelated mechanical issue — see attached documents for more information.

(1)the original 12-v battery was replaced by the dealership on xxx (after 5-week and 120-mile usage) with a new one, model: 00544-mfh50, s/n [xxx], 540cca and 100 rc. (2)upon double-checking with the 2026 Lexus owner’s manual for Rx450h+, on page 605, it clearly stated that when replacing the battery, its case size should be the same as the previous one (ln3) ……. With a performance rating of cca of 603a or higher. (3)the dealership indicated the 00544-mfh50 was the right battery based on the VIN number per Lexus internal database. The database also showed another battery model: 28800-31572. (4)however, according to the battery information at [xxx], both 00544-mfh50 and 28800-31572 are listed as “does not fit” the 2026 Rx450h+ vehicle. (5)the other battery, model 00544-21171lxpr, is listed as the hv 12-v battery for the 2026 Rx450h+ at [xxx]. (6)also on the Lexus parts website, this 2026 Rx450h+ VIN number is recognized as Rx350h (base trim), a totally different vehicle. It may be possible that the Lexus 2026 Rx450h+ owner’s manual (published in [xxx], 2026, for the north american market) and [xxx] have been updated with the correct 12-v battery information, while the internal Lexus database was not. It was not clear whether factories in [xxx] or elsewhere, and [xxx] dealerships, still use the possibly outdated and conflicting information for initial battery installation and replacement when needed. The discrepancies between Lexus internal information (manufacturing and dealership) and publicly available information from the owner’s manual and official Lexus website caused significant confusion about which battery is the right one designed for this vehicle in 2026. Details please see attachment. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 12-v battery of a brand-new Lexus Rx450h+ died suddenly without any warning, only about 5 weeks into regular driving, with ~120 miles on the odometer. Lexus roadside assistance was called in to jump-start the battery, and the vehicle was driven directly to the dealership (about 5 miles away) for service. The dealership service checked the battery and indicated it “passed” all tests and is in "good" condition. However, the service technicians could not identify or suggest any reason for such a sudden death of virtually a brand-new battery (5-week new, 120-mile usage). The dealership indicated that there is nothing they can do for the battery because Lexus warranty protocol would not allow them to replace it. The Lexus engagement center was also contacted, and they indicated that, per Lexus protocols, they could not do anything about it, except documentation on the battery failure and file it for future reference. The customer considered this suddenly “failed” battery as a serious safety concern, because it is completely unknown how and why it happened suddenly in the first place. The customer repeatedly discussed and/or emailed such concerns to both the dealership and Lexus engagement center staff on the same matter, only requesting to replace the “failed” battery with a new one. Both dealership and engagement center concluded no replacement can be done, only “continued monitoring” of the failed battery, citing Lexus protocols. However, the dealership service department also acknowledged there is no way for any customer to monitor this 12-v battery with either onboard displays or Lexus app, as the 12-v battery condition is not being monitored by the existing Lexus software. Only another unfortunate incident or even fatal accident due to this “dead” battery could be the outcome of such “continued monitoring” and documented “repeated” failure. After that, they may be able to involve Lexus field engineering team to investigate it further.

2026 Lexus Rx 350h luxury awd hybrid. Component affected: electrical system:12v battery, digital/electronic locks I am experiencing a severe and persistent 12v parasitic battery drain on my 2026 Lexus Rx 350h. The vehicle's auxiliary 12v battery drains completely to a dead state if left parked and unused for only two to three days. This is an ongoing manufacturing or software defect that prevents the auxiliary battery from maintaining an adequate charge, resulting in routine vehicle failure. Safety risks and incidents: this parasitic drain introduces several critical safety hazards: 1. Emergency entrapment and lockout risk: because this vehicle relies entirely on electronic door latches (e-latch), a completely depleted 12v battery causes the exterior and interior electronic door release buttons to fail completely. This creates an immediate risk of vehicle entrapment or leaving passengers locked out in dangerous environments if they are unfamiliar with the secondary manual emergency release overrides. Stranding hazards: the rapid, unpredictable nature of the battery depletion regularly leaves the driver stranded without warning in remote locations, dark parking areas, or during extreme weather conditions. Loss of connected safety features: when the battery voltage drops severely before dying completely, critical connected vehicle safety systems—including automated emergency crash notifications, location tracking, and roadside assistance connectivity—are entirely disabled, presenting a severe risk in an emergency. Despite dealer awareness, battery replacements, and attempts to mitigate the drain, the manufacturer has not yet provided a permanent software or hardware fix to resolve this electrical defect. Yesterday, 8/31/2026 I took a 30 mile trip after fully charging the 12 v battery to 100%. Upon returning, I installed my battery maintainer. The maintainer stated 53% charge. The vehicle was not adequately charging while I drove. Vehicle software is malfunctioning.

My rear windshield shattered - I was not driving - I was not using the rear defrost - I simply put car in reverse and when I looked back my glass was shattered. 08/09/2026.

Battery drains which locks car unexpectedly. No warning, even with car fob inside car which creates a safety issue if child or someone is in the car. All doors lock and with no access to fob cannot open the door with manual key. Also, safety issue if this happens at night or in a parking lot etc. Cannot open doors at all - there is obviously an issue with the battery draining after only a few days. Dealer solution - plug in a battery maintainer - problem if you are parking the car at an airport for multiple days. No place to plug the car in. . . Lexus needs to figure out what is draining the battery or some fix to stop this from happening - I drive my car several times a week 30 miles at least - still happens. Have had to replace battery twice so far.

The vehicle has exhibited intermittent drivability and safety-related concerns after a prior collision repair. The concerns include delayed acceleration/engagement, abnormal jerking or stopping behavior, and elevated rpm behavior during real-world driving. The most recent documented event occurred on July 27, 2026, while the vehicle was in drive at approximately 50 mph with cruise/driver-assist indicators illuminated. The tachometer appeared near the 4,000 rpm range. The event was captured by video/screenshot and the vehicle is available for inspection upon request. The issue creates a safety concern because delayed acceleration, unexpected jerking/stopping, or abnormal rpm behavior could affect the driver’s ability to safely merge, maintain speed, respond to traffic, or control the vehicle during highway or road driving. The problem has been intermittent and has not always produced an active warning lamp. A Lexus dealer inspected/scanned the vehicle on may 21, 2026 and discussed eco mode/normal drive mode, but the symptoms continued afterward. The vehicle has a documented post-repair history involving transmission cooler replacement, transmission-fluid concerns, and prior transmission/powertrain/electronic-control diagnostic code history. Lexus brand engagement has also been notified under an active case, but there is currently no clear authorized Lexus repair path. The exact failed component is unknown. Based on the symptoms and repair history, the concern may involve the power train, speed control, electrical/electronic control system, or related driver-assistance systems.

Dear sir or madam. My name is [xxx], [xxx], [xxx] living in [xxx]. I bought my 2008 Lexus Rx400h car, used, in 2014 at a non-Lexus dealership in the [xxx] where I used to live. My Lexus VIN [xxx]. I've been satisfied with the car. . Until today. The car had been running smoothly forever, and this morning while I was driving I came to a stop (red light) and the car suddenly shut down completely, including the loss of lights, and the whole dashboard went dark. Other cars behind me were honking their horns. I could not even turn on the hazard lights. After 1-2 minutes, all of the lights/warnings started coming on one after the other. I started the car again and run around three different errands without having further issues. I checked online to see if other owners had experienced a similar situation, which is the case. One person said that there had been two recalls in 2011 and 2013, both related to the inverter module inside the hybrid system. Although, I called today a Lexus dealership, [xxx], located in [xxx], and I was told there are no recalls for the VIN number that I provided. Another owner said she/he went to a Lexus dealer in [xxx] and she was told it was a defect in the gutter drainage design and that water gets into the hybrid system. This is a dangerous and potentially catastrophic situation if the vehicle suddenly shuts down on a freeway/highway putting passengers in risk of harm, injury, or death. This is a horrific defect which Lexus should correct immediately with a recall before one of us ends up at the cementery. I am glad to know that organizations such as the NHTSA exist, and I will appreciate very much that immediate action is taken on this matter. Sincerely, [xxx].

Vehicle jerking back and forth aggressively while at a complete stop with foot firmly on brake pedal. Vehicle seems to want to lurch forward.

*driver-side entry failure = primary access point compromised * could trap occupants if internal handle fails or after an accident * emergency responders rely on driver-side access first * this is not normal wear and tear—it’s a safety-related failure.

Vehicle was parked, engine off, and unattended. An internal electrical fire originated in the overhead/sunroof wiring area. Damage includes melted wiring harness near the sunroof, burned center console, and soot throughout the interior. The fire originated in a constant-power electrical circuit and spread downward into the cabin. There were no aftermarket modifications, no external heat sources, and no objects in the vehicle that could have caused ignition. Ambient temperature conditions were normal and insufficient to cause this damage. This represents a serious safety defect because the fire originated spontaneously within the vehicle’s electrical system and could have resulted in a full vehicle fire or injury if occupants were present. The failure appears to involve factory-installed wiring/components and is not consistent with normal wear or external factors.

Car stopped running during turn. Then started creeping along ,then after a bit ,started working normally. Happened a few times after. Then later car wouldn’t start in garage, had to get jumpstart. Took to Lexus dealer and found out the 12 volt battery was shot. They replaced it. Very frightening experience. Could have had an accident.

The contact owned a 2024 Lexus Rx 350h. The contact stated that while the vehicle was parked and running, it unexpectedly turned off with the electronic malfunction error message displayed. The vehicle could not able to be restarted, and the contact was unable exit the vehicle due to the failure of the power locks. Roadside assistance assisted with removing the contact from the vehicle. The vehicle was taken to the dealer, where it was diagnosed with battery failure. The contact was informed that the battery needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer and remained with the dealer. The dealer was not contacted. The vehicle was not diagnosed or repaired. The dealer attempted to return the vehicle back to the residence. The contact was concerned about the issues with the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 1,624.

I am reporting a recurring electrical and mechanical system failure on a 2024 Lexus Rx 350h luxury. On [xxx], the vehicle suffered a total power loss that rendered the electronic door latches unresponsive to all inputs. Because the occupants were a [xxx] and a [xxx] strapped into car seats, they were physically unable to reach the interior manual overrides. Critically, the mechanical backup key also failed to unlock the vehicle from the exterior, preventing immediate rescue. This created a life-threatening entrapment scenario. The doors only responded after multiple minutes of repeated manual attempts. Once entry was gained, the vehicle would not start and the headlights began blinking rapidly, indicating a total system communication failure. I had to use jumper cables to restore power. This is the second occurrence of this catastrophic failure, documented on repair order [xxx] at Lexus of westminster. The failure of both electronic and mechanical failsafes constitutes an extreme occupant safety hazard. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

A 2024 Lexus Rx 350 h 12 volt battery is discharging leaving owners stranded. Aaa must be called to jump the battery. This has happened four times, each when opening car doors to clean the vehicle. From my understanding the battery discharges within 5 minutes leaving the auxiliary system without power and the inability to start the car. Not exactly sure what is causing the battery drain but vehicle becomes unable to move, open doors or move since drive train will not allow any movement. Owners have been stranded four times waiting on help. Dealer unsure of problem but exploring electrical issues, battery issues, software issues or unknown issues.

I own a 2020 Lexus Rx 450h with approximately 129,803 miles. The check engine light came on and the vehicle stored diagnostic trouble code p0a2d, which indicates a failure of the drive motor/temperature sensor circuit that is integrated into the transmission/hybrid motor assembly. According to the Lexus dealer’s diagnosis, the temperature control sensor located on the transmission/hybrid drive unit has failed. Because Lexus designed this sensor as part of the transmission assembly, the dealer has stated the sensor cannot be replaced separately and that the only repair is to replace the entire transmission. Lexus is refusing to acknowledge this as a manufacturing defect and is requiring me, the consumer, to pay the full cost of a complete transmission replacement, estimated at approximately $9,040. 03, solely due to the failure of this internal temperature sensor. This is a critical component used to monitor drive motor/transmission temperature. A malfunctioning sensor of this type can lead to improper system operation, possible overheating, loss of power, or unpredictable behavior of the hybrid drive system while the vehicle is in motion, which presents a safety risk to occupants and other road users. This failure occurred during normal use on public roads and not due to any accident, abuse, or modification. I am requesting that NHTSA investigate whether there is a design or manufacturing defect in the drive motor/transmission temperature sensor and its housing or circuitry on the 2020 Lexus Rx 450h (and related Toyota/Lexus hybrid models) that forces owners to replace the entire transmission when this internal sensor fails. This appears to be an unreasonable safety?related defect and an unreasonable repair burden on consumers.

My 2024 Lexus Rx 350h experienced a catastrophic 12v battery collapse (2. 00v), disabling the electronic 'e-latch' door system and rendering interior handles non-functional for standard use. While a manual override exists, it is not intuitive for emergency egress. Additionally, the electronic parking brake and shift-by-wire systems remained physically locked, preventing the vehicle from being moved to a safe location during the power failure. I am reporting this as a failure of primary safety and fail-safe protocols. Dealer did not consider this a a problem because he said I “needed to read the manual before I ever drove the car”.

My Lexus 2019 Rx450h is making a squishing squeaking brake actuator noise when pressing the brake pedal. I located well publicized TSB’s documenting the awareness by Toyota/Lexus of the problem. (TSB: mc-10245447-9999) brake squawk/knock noise. I checked with my local Lexus dealership to see if my vehicle had been repaired. It had not!. Temecula valley Lexus, 42081 dealer drive, temecula, CA. 92591. (951)365-6834. I scheduled an appointment for repair on 1/26/26. They rejected making the repair because my vehicle did not have any codes in the computer or any lights on the dash. They did in fact, confirm the brake actuator noise. I reject that concept because who could know ahead of time if a part experiences a (1st time) total failure without throwing codes and turning on dashboard lights? as I read the symptoms of severe problems experienced in a higher level of failure by brake actuators, I would not want to have to experience a crash accident in which the actuator would operate correctly in a hard stop condition or have abs failure and brake lockup occur. Personal harm and property damage should not have to be an indicator if I can have the manufacturer cover a repair. Please advise what I should do to increase the response in the direction of getting this known problem repaired.

If we don't drive the car for 4 or 5 days, especially in cold weather, the car will sometimes not start due to a drained 12v battery. We've spoken to Lexus of rockville, MD and Lexus roadside assistance, who are aware of the issue but say the 12v battery is "healthy. " online research shows this is a widespread known issue with Lexus Rx350h and Rx500h vehicles from 2023 onward: [xxx] [xxx] . A simple software update to ensure that the high-voltage hybrid battery charges the 12v battery to a greater extent when the vehicle is parked should solve the problem, but Lexus has so far not addressed this problem.

I purchased this vehicle on January 5, 2026, from a family-owned dealership in broken arrow, ok. The vehicle was purchased “as-is” with a guarantee of sale and a carfax report. After purchasing the vehicle, I drove it home and it remained parked until January 8, 2026. On Thursday, January 8, 2026, the vehicle experienced an unexpected engine stall while I was driving. At the same time, the slip indicator light and traction control appeared to engage. I contacted the dealership immediately to report the issue, and the vehicle was towed back to jt wholesale auto sales on Friday, January 9, 2026. On Tuesday, January 13, 2026, I was informed by the dealership that the vehicle had undergone a complete inspection and that no mechanical issues were found. Relying on this representation, I retrieved the vehicle and drove it home. However, after retrieving the vehicle, I continued to have concerns regarding its condition. On Thursday, January 15, 2026, I took the vehicle to stellar auto service located at 2209 n. Yellowood Ave. , broken arrow, ok 74012 for an independent inspection. Stellar auto service specializes in Lexus and Toyota vehicles. During their inspection, they identified the following issues: • engine timing chain cover leak • worn drive belt stellar auto service was informed of the slip indicator light activation and the engine stalling that I had experienced. However, at the time of their inspection, they were unable to identify or reproduce any issues related to the slip indicator light or the stalling concern that I reported. On Sunday, February 15, 2026, the slip indicator light illuminated again, and the vehicle stalled while in operation. I was forced to safely pull off the roadway. I turned the car off, waited, restarted the vehicle, and drove home. The same issue occurred again on Sunday, March 8 and 15th, 2026. While driving, the slip indicator light illuminated and the vehicle stalled. I pulled off the road turned the vehicle off, restarted it.

The 2023 Lexus Rx-350 has had complete 12 volt battery failure twice in the last year. The hybrid battery charging procedure for the 12 volt battery is insufficient. Twice I have been stranded. The frequency and duration of the hybrid battery charging is not sufficient. A more powerful 12 volt agm battery is needed. The dealer says I am not taking sufficiently long trips to charge the battery. Last Saturday I took two 30 - 40 minute trips but the battery had only 11. 8 volts requiring a 100% charge. There should be a recall to fix this problem.

Car left us stranded 12 v battery completely dead had a lot of difficulty trying to get it started. The unfortunate part is I got rid of a 2023 Lexus Rx 350 h for the exact same problem could not get resolved after installing five batteries. Now we’re going down this road again.

On at least 7 occasions the driver was trapped inside the vehicle. The car failed to start and the doors and windows locked. If the driver had not had a cell phone to make an emergency call he would have been locked inside until someone discovered the problem. Had this happened in phoenix, az in the summer, there is a very good chance the driver would have been dead before he was rescued. The last time was December 11, 2025. We replaced the starter battery for 2nd time in 2 years and 40k miles.

I was dropping my husband off at cardiac rehab. I was stopped and had my foot on the brake suddenly the car launched forward into the back of a car parked in front of me. The other driver got out of the car and said he wasn't hurt. We were able to drive the car home stopping 3 times to pull pieces of the car off that were dragging on the road. We took the car to a mechanic at the end of the road. He scanned the codes for us. Pre-collision 2 clall ; intuitive park assist clall front sensor comm. Circuit ; front recognition camera clall ; lane keeping assist clall front radar sensor incorrect axial gap ; bcm b124b light source sensor open/short. The insurance adjustor totaled the car and they picked it up today. No warning lights showed up on the dash until after the accident.

The car battery goes dead when car not used in 14days, or not driven on freeway long enough to top off battery. We've had to jump it for being in a cool garage for a couple of days, and the battery is only 2yrs old. The car needs a stronger battery.

I bought this vehicle last Thursday, the new Lexus we only drove it three times, but all power down. The first time we were about to go to work, the whole vehicle no power, so I checked the battery, it was 10 volts, so I used my crv battery turned on Rx350, it's working, second time, when I arrived my work place, I turned off the new vehicle, the whole power down again, after I checked the battery, it showed 12 volts, after I checked the battery, the power came back. The third time, after working, I got totally locked outside the Rx350, I tried so so many times, the whole power was gone again, so I broke the handle and used the key get into the car, and checked the battery, still 12 volts, after my checking battery, the power back again! so I am sure it's not only the battery problem, but also power management module something wrong with it, or a module named 89690-0e011 is damaged , I am very sure the new Rx350h needs very very professional technician repair, this vehicle has serious safety hazards and poses a threat to life and safety.

I purchased the 2022 Lexus Rx 350 used a couple of months ago. While driving down the highway the instrument panel went blank. I was terrified. I continued to drive not knowing what speed I was driving. The instrument panel went panel came back minutes later. Another incident occurred when the car was parked in my driveway. I turned on the engine and the instrument panel was blank. No numbers and no information on the instrument panel. As I drove down the street slowly the instrument panel returned to normal. A third incident occurred when occurred as we were driving on the highway. The light on the instrument panel began to darken. My husband was driving and I was in the passenger seat I was able to access the light app on the dash and restore the light to the original setting. This car is not on the recall list. It should be because this is a matter of life or death. The car had 59000 miles on it when we bought it so it is not under warranty. I contacted Lexus and they refused any help until I take it to a Lexus dealer and have it diagnosed. I don’t drive it daily because I have other vehicles but I would like to be able to drive it and have full use of the instrument panel. The problem repeats itself.

I entered then attempted to start my Lexus on November 11, 2025. The car would not start - the dashboard lights fleshed briefly, then the car was completely dead. There was not a light on anywhere. The doors would not open and the windows would not roll down. I was trapped. Fortunately I had my cell phone so I was able to call my wife who was inside of our house. She could not open the door with the manual key, she called aaa. The tech hooked up some power device under the hood and the car started and seems ok. This was frightening. I was trapped in the car and running out of air. I could have suffocated.

The contact owns a 2024 Lexus Rx350h. The contact stated while attempting to start the vehicle, the vehicle failed to start as intended. The contact stated that the doors failed to unlatch, and the key fob failed to function as intended. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. Additionally, the failure had occurred while the contact and her husband were occupying the vehicle. The contact stated that luckily the weather was not cold, or a baby was not in the vehicle during the failure. Aaa was contacted and provided a jumpstart to the vehicle. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 16,342.

Battery on car under 6 months old and fewer than 3,000 miles was dead after not being used for one week. Weather was not an issue, as car was parked inside of residential garage.

While driving, the instrument panel went blank. I believe it is not safe to drive with no instrumentation or knowledge of your vehicle or speed. The dealer confirmed it needed a software update and performed this yesterday. We were not advised of this needed update, no recall or no communication from the manufacturer. We should be advised when something this critical is needed.
