AIR BAGS, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
After slowly making a left into a parking space at Dunkin Donuts and trying to deploy my brakes, my car lunged forward spontaneously accelerating, jumped two curbs and hit a barrier and the window of the store. The impact of the crash wrecked my front end and the radiator was damaged and was laying on the ground. With this intense impact, the airbags did not deploy on impact. My insurance agency totaled the car. After the crash the warning came on the screen that the Collision System had malfunctioned.

UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM, POWER TRAIN
First incident. 71 mph, 101 degrees out traveling along a straight highway, I hit the seat cooler button and when I did, my car lost power. I could not get any response when I hit the accelerator. I tried several times. This was on XXX with around 500 miles on the car in the odometer. I had it less than a week. Second incident on XXX 25 mph, 105 degrees outside with 1300 miles in the odometer, I again, lost power and was unable to accelerate. I was on a windy road that required the use of both hands on the wheel. With this incident I lost the AC in the cabin. I had to pull over both times and turn off my vehicle and turn back on. There were no lights, or warnings or beeps letting me know that my car was going to lose or lost power. I took the vehicle to Crown Lexus in Ontario, they had it for 7 days and they could not find anything wrong with it. When they ran a diagnostic on it, there were no codes other than they said I put the car in neutral while driving. Which did not happen. My husband was with me both times. I then had the car towed to Lexus of [XXX] and we went for a test drive, as they wanted to see how I drive to rule out human error and to see if the car would have another incident. It did not. They kept it overnight and could not find anything. The first dealer drove it about 70 miles and the second around 10 miles to diagnose. The green ready light was on the dash. As to what component failed? I am not sure other than I could not accelerate and the ac went out. My safety and my husbands, along with other drivers, was put at risk due to the fact my car was traveling at a high rate of speed and it just lost power. I could have been rear ended. I could have been on a road without a shoulder to move over to. This could have been a major catastrophe. The dealer(s) have been unable to reproduce the incidents. There has been no inspection other than at the dealer, and during both incidents, no warning lights, or beeps were seen or heard INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

FUEL/PROPULSION SYSTEM
There are recalls for 2017 Lexus RX350’s for their fuel filters being faulty. Mine is not on the list. I have taken my car to many mechanics and in the last few months I’ve had my front and back brakes replaced, new struts, new tires and more done on the vehicle and nothing is helping. They have checked my mass air flow sensor, oxygen sensors, spark plugs, transmission and everything they can think of to try and see why it is having such a hard time transferring power to the wheels and being very sluggish. I’ve replaced air filters, done fuel additives and many other things, there are no error codes or any stored codes. I am left to only think it is the fuel filter/system and my vehicle is part of the list affected. I noticed the changes in the vehicle about 20,000 or so miles ago and it’s gotten worse. I’m not sure what else I can do at this point.

POWER TRAIN, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
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.

EXTERIOR LIGHTING, POWER TRAIN, UNKNOWN OR OTHER
1. Ignition System: While driving the key in the ignition lock came out loose! Exremely frightened and managed to pull the car over to a driveway. But, the car could NOT be stoped using the key fob. Key will not work to stop the engine. Very unusual and unexpected incidence. 2. Lighting system switch: Suddenly the knob of the light switch came out loose with a plastic shaft and will not turn on the light. Very unsafe while driving and it became dark due to storm and rain, and I wanted to turn the headlights for safety. I beleive it is a manufaturing defect and causes severe safety issue.

POWER TRAIN, UNKNOWN OR OTHER
While on a long road trip on a hot day, on the interstate, the car suddenly lost speed and would not accelerate. It was like the car had shifted into neutral. I was coasting on the interstate, steadily slowing, and was forced to pull over to the shoulder. I turned the car off and waited a couple of minutes then turned the car back on. No error messages were displaying at that time. About 5-10 minutes later, I pulled over for a planned stop. My husband assumed driving responsibilities when we got back into the car. Upon trying to get back on the interstate, the car would not accelerate, and multiple errors error messages appeared, including: ""System Malfunction/Visit Your Dealer," "Check Engine/Visit Your Dealer," "Drive-Start Control Malfunction/Visit Your Dealer," "Secondary Collision Brake System Malfunction/Visit Your Dealer," and "Traction Control Turned Off." He pulled into a nearby parking lot where we had to have the car towed to the dealership. It felt like the car was in neutral when this happened both times.

POWER TRAIN
On July 21st, 2026 while stopped at a red light and upon turning green stepped on the accelerator to transition from stop to start, the vehicle suffered a sudden, catastrophic loss of motive power. The engine failed to respond to accelerator input, leaving the vehicle stranded in active traffic. This created an immediate rear-end collision hazard in a busy intersection. I was forced to coast the vehicle out of traffic to the side of the road, cycle the ignition off, and reset and temporarily regain powertrain functionality. Also on July 25th, 2026 I lost the power to accelerate on the highway when I was cutoff. I put the car in neutral and then back in drive to get power back to accelerate. These are the most recent, But I have had 2 transmission replacements. At separate times and then a re flashing to upgrade computer information another time. All within a 7 month period. This is a known issue by Toyota Motor Corp and has been circulated by the company under TSB-L-SB-0059-23.

ENGINE
I am reporting a safety issue with a 2016 Lexus RX350, VIN [XXX], with about 60,000 miles. The vehicle is registered in [XXX] and was being driven to [XXX] when it suddenly overheated on XXX near [XXX]. The warning lights appeared while the vehicle was traveling at highway speed. The driver immediately took the first available exit within about one minute. The failed system appears to be the engine cooling system, specifically the water pump. The vehicle is currently at Kendall Lexus of Eugene and should be available for inspection. This failure created a safety risk because it happened suddenly on a major highway. The driver had to exit quickly and the vehicle became disabled far from home. A sudden coolant-loss or overheating event at highway speed can leave drivers stranded in unsafe locations with very little warning. Kendall Lexus of Eugene inspected the vehicle. Their Service Manager stated in writing that the technician found a leaking water pump, misfires in every cylinder, and a 95% leak in cylinder #6 through the exhaust valves. She stated that the water pump failure caused the vehicle to lose coolant, overheat, and suffer internal engine damage requiring engine replacement. Lexus Customer Relations has been notified under Case #XXX. Whether Lexus corporate has physically inspected the vehicle is unknown. Before the incident, there were no known warning signs. The warning lights appeared five hours into the road trip when the overheating occurred. After exiting, the driver let the vehicle cool for 30 minutes, checked for visible leaks, and tried to continue only briefly around the block. The warning returned almost immediately, so the vehicle was towed. This vehicle has extensive Lexus dealership maintenance history. Lexus quoted about $20,000 for engine replacement. Lexus has issued TSB L-SB-0039-20 / NHTSA ID 10183269 regarding water pump leak inspection and diagnosis, but there appears to be no rec INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My wife was driving the subject car She intended to come off the road to give a way to on coming car. She got in naghbour's drive way and intended move 10 feet. When she tried to put more gas to move the car was hyper accepting drove 50 feets away and hit naghbour's ion gate and stopped. When she back off it did again and hit street lamp. It did two more time. Ended up damaging 4 corners of the car and all the material that the car hit. I could not understand that she hit the 4 corner of the car. That is why I suspected engine problem. When I tried the same movement nàghbour came out and worry that the car will do the same thing. While I was talking to him. He told me he has security camera and he noticed excess unning of the engine. He sent me the clip I couldn't see the car but certainly I could hear the engine. The end of the report.

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 is: [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].

The panoramic sunroof has a shade, which is not closing. This causes a lot of sunlight to enter the vehicle which might be harmful to your skin and causes headaches. The repair is very expensive and there is no other way around it. I seen many owners raising concerns about the same issue happening to them, on youtube, reddit, google and other websites. This is an issue on the same model from around 2017-2022. This must be repaired by lexus, and improved so it doesn’t keep happening.
