SERVICE BRAKES
Vehicle: 2014 Lexus RX 450h Component: ABS / Brake Actuator System I am submitting this complaint regarding a safety-related brake system defect in my 2014 Lexus RX 450h. The vehicle experienced ABS/brake actuator failure consistent with a known defect that was previously addressed by Lexus/Toyota through a Customer Support Program (extended coverage program, not a recall). I was never notified of this program. I have confirmed that Lexus mailed notification to an incorrect address (Temple City), despite the fact that my vehicle registration address has never changed and has always been accurately maintained with the DMV. As a result, I was deprived of the opportunity to repair a known safety-related defect within the coverage period. Key facts: - Brake/ABS actuator system failure occurred at approximately 150,000 miles - Lexus had previously issued a Customer Support Program for this known defect - No notification was received by me during the coverage period - Lexus confirmed notices were sent to an incorrect address - My DMV registration address has remained unchanged I raised this issue directly with Lexus Customer Assistance, including escalation to a supervisor. Lexus denied goodwill assistance and stated no remedy is available despite the documented notification issue. This raises concerns regarding: - Adequacy of manufacturer notification procedures for safety-related defects - Potential failure to reasonably notify owners using accurate registration data - Loss of repair opportunity for a known braking system defect due to administrative error Because this involves a braking system (critical safety component), I am requesting that NHTSA review whether the notification process used for this defect was adequate and whether other owners may have been similarly affected. Supporting documentation is available, including proof of DMV address history and evidence of incorrect mailing address used by the manufacturer.

STRUCTURE:BODY
The panoramic sunroof shattered while the car was parked and there were no occupants. Lexus USA refuses to acknowledge this defect and the dealership insists there was an impact that caused this damage. There was no impact. I have asked the dealer for a written report of their determination of the point of impact and to return all broken glass to me. I do not know yet if they will comply with either request. As the car was parked, there were no immediate safety concerns, but due to the risk of additional glass falling onto the driver and passenger seats, the car was not in a drivable condition. Had this happened while driving, the sound of the shattering and the glass falling may well have resulted in a reaction from me causing immediate danger to myself and others on the road. UNKNOWN if problem has been reproduced, but this is not an isolated incident. Vehicle component had not been inspected by manufacturer, police , insurance reps or others. There was no warning or other symptoms of this problem.

ENGINE, POWER TRAIN
My 2023 Lexus RX350 with 67,000 miles displayed a check engine light along with a Drive-Start Control Malfunction warning. The vehicle was brought to a Lexus dealership where it was diagnosed with fault code P25B372 — Turbocharger Wastegate A Actuator Stuck Open. The dealership confirmed the wastegate actuator has failed and requires replacement. The part is currently on backorder with over 800 units backordered nationally, indicating this is a systemic issue affecting multiple vehicles. Toyota has issued Technical Service Bulletin T-SB-0084-23 covering this exact fault code on the same 2.4L turbocharged engine used in the 2023 Lexus RX350. The bulletin states the repair is covered under the Federal Emission Warranty for 96 months or 80,000 miles. However, the Lexus dealership has declined warranty coverage citing the absence of a Lexus-specific bulletin, despite the identical engine and fault code. The failure puts safety at risk as the Drive-Start Control Malfunction warning indicates loss of traction and stability control systems. The problem has been confirmed by the Lexus dealership. Warning lamps appeared on the dashboard prior to the visit. The vehicle is available for inspection upon request.

I was driving on the highway and suddenly there was a loud explosion and the sound of hundreds of time things or debris hitting my car. Thankfully I did not hit the brakes or lose control of my vehicle, but I easily could have! I then saw little pieces of glass falling off my car from my rear view mirror. I pulled over to find that it was my sunroof. There was no impact from anything, the glass was pointed upward as if the explosion came from inside. This was incredibly scary!

The passenger rear tire (235/60R19 - Michelin Primacy A/S) randomly blew out while driving at high speeds on the highway. No trauma via a pothole or other object was noted. Tire was inflated to the manufacture recommended PSI (33 PSI). No signs came up until the tire blew out. The tire just randomly decided to give out while driving.

ENGINE, FUEL/PROPULSION SYSTEM
While driving the engine stalls. It has jolted back-and-forth at times and had to be taken to a dealer. It’s still stalls when trying to slowly accelerate especially uphills. Low gas mileage barely getting 18 miles per gallon. Warning lights flickering while car stallling. It’s like it’s having a seizure. This has happened a few times.

Around 11 am on Sat., May 2, 2026, I was sitting in a very long line in Starbuck's drive thru when my 2025 Lexus RX hybrid suddenly and uncontrollably accelerated--like an uncontrollable bucking horse. Brakes didn't work. I couldn't stop my out of control car, and the multiple computer sensors also didn't stop the car. It was like the throttle was engaged because of a computer glitch. In an effort to avoid hitting the car in front of me, I immediately tried to swerve, but still hit the car, then jumped the exceptionally high curb and ended up in the grass below and almost into the busy road ahead of me. It was terrifying. The car in front of me hit the car in front of her. The exact same issue happened to me on June 18, 2025 when my car unintentionally accelerated--also in a very tight space and going at 2 mph. There was no accident at this time because my car's computer stopped me from plowing into the building immediately in front of me after unintentionally accelerating. The next day at the recommendation of the person who sold me the car, I took my new Lexus to the service department. They gave me a loaner and told me to contact Toyota's/Lexus' Brand Engagement department in order to start the review, which I did. The review was conducted and ended around July 9, 2025 . On Mon., May 4, 2026 I took my car back to the Lexus dealer where I purchased, but was not given a loaner, which I requested, and was told I would need to wait several hours to have this inspected. I then took my car to Boyce Body Werks. A State Farm agent examined my car and initially approved almost $24K worth of damages. Boyce Body Werks is saying when they disassembled my car that there was more damage underneath my car. I also notified Toyota/Lexus about the same issue that happened one year prior. They also refused to give me a loaner, and I am now forced to pay my rental fees. Boyce Body Werks--a Lexus certified dealer has multiple pictures of the damage. My car is still under warranty.

AIR BAGS, SEAT BELTS
The car does not alert when a seat belt is not worn in the back seats. This feature is mentioned in the owner's manual, but the car fails to alert when a rear passenger does not buckle their seat belt. I have raised the complaint twice and proved to lexus service center, that car doesn't warn or alert the safety belt. It was also proven and checked by Lexus with their technician. The problem is accuring right from the time car was purchased, When check with the dealer it was designed , but their manual confirms the seat belt not worn warning light is included in the package. It put the any passener riding mainly children at serious risk

FUEL/PROPULSION SYSTEM, ENGINE
I was looking at common problems associated with the make and model of my car. I came across an issue that could possibly cause engine failure. I am unsure if any one has reported it yet. here are the details - Problem overview An VVT-i oil line on the Lexus RX350 is known to burst. This is a very large leak which covers the ground, engine, and undercarriage. If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate. Continued use after these warnings will result in complete engine failure due to oil starvation. The line is known to be defective, and a revised part has been issued by Toyota, however, this revised part is known for the same issue. To repair the issue, the line must be replaced, and the engine bay and undercarriage must be cleaned thoroughly. The problem has occured generally around 120k miles. Here is the link to the website that has collected information from 116 users. Requesting you to please check if this a problem that needs a recall? [XXX] ely report it.

POWER TRAIN
I am experiencing ongoing issues with my 2023 Lexus RX500h related to the powertrain/transmission. The vehicle has exhibited abnormal shifting behavior, including hesitation, jerking, and inconsistent acceleration. At times, the vehicle does not respond smoothly when accelerating, which raises safety concerns, especially when merging into traffic or driving at highway speeds. The issue occurs intermittently and has persisted despite multiple attempts to diagnose or address the problem. The condition affects the drivability and reliability of the vehicle and has not been resolved.

SERVICE BRAKES
I am reporting a serious and potentially dangerous braking issue with my 2007 Lexus RX400h. The vehicle currently has approximately 126,296 miles. While driving, the vehicle emits a continuous and intermittent warning beeping sound. At the same time, the braking system becomes unreliable. The brake pedal becomes extremely difficult to press, requiring excessive force, and the vehicle does not respond consistently when braking. In addition, there are instances where the vehicle appears to brake unpredictably or inconsistently, which creates a significant safety hazard for myself, passengers, and other drivers on the road. Based on my research, this issue appears to be related to a known defect involving the ABS brake actuator assembly. Lexus previously issued a warranty enhancement program for this component due to internal malfunctions that affect brake pressure and system performance. However, this issue was not issued as a formal recall tied to VIN eligibility. Despite my vehicle being under 150,000 miles, I have been informed that I may be outside the time-based warranty window, and no active recall is listed for my VIN. This defect directly impacts the braking system, which is a critical safety component. Failures in the brake actuator can lead to improper brake pressure, reduced stopping ability, and increased risk of a crash. Given the safety implications and known history of this defect, I believe this issue warrants further investigation and potential recall consideration. I am submitting this complaint to request that the NHTSA review this matter for safety risk and determine whether broader action is necessary to protect consumers.
