Was pulling into parking spot when car went haywire and started accelerating on its own. It would not stop until it has hit 5 cars and crashed into a cement wall. The brakes did not stop the acceleration. This occurred at the exact same time there was an incoming call which was not answered. The airbags did not deploy. The car appears to be totaled and has been towed to a state farm affiliated auto yard. There were no indicator lights that something was wrong but the Lexus app showed 5 warnings that came in to my text messages same day. These 5 alerts are indicative of exactly what occurred.

My vehicle caught fire a few days after being repaired by a licensed repair shop in California. ?the repair was performed brodie's tire & automotive?address: 1276 petaluma blvd n, petaluma, CA 94952?phone: [xxx] after the fire, the repair shop admitted in writing that: • the intake manifold melted after the fire?• the engine became “not repairable”?• the fire occurred shortly after their repair?• they offered to “fix it for free,” which indicates awareness of responsibility the fire caused severe heat damage to the engine compartment, electrical wiring, and surrounding components. The vehicle became unsafe to drive, and the engine can no longer operate. This incident presents a serious safety hazard because the fire happened shortly after a repair that involved components near the engine and fuel system. Improper or unsafe repair work may cause similar fires for other consumers. This incident is already under active investigation • California department of insurance (cdi) – complaint #xxx• California bureau of automotive repair (dca/bar) – case xxx I am reporting this to NHTSA because the fire and melted engine components indicate a dangerous defect tied to improper repair work, which may pose a risk to other drivers. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The electronic screen on dashboard that displays map, hvac, etc. Turns pink then black and disappears for several minutes. One then has no control over the various functions displayed on the screen. I've done a hard reset by disconnecting the battery for several minutes. . . To no avail. Thank you.

My 2021 Lexus Rx 350 (mileage approx. [19,000], has developed a severe mold contamination issue caused by hvac condensate drain failure. This issue is a known design defect covered by Lexus technical service bulletin l-sb-0020-21, which identifies blockage or poor drainage in the hvac system that allows water to enter the cabin. As a result, water intrusion under the carpet has led to mold growth, making the vehicle uninhabitable and unsafe to drive. The cabin now contains visible mold and musty odor, raising serious health and air quality concerns. I brought the vehicle to Lexus of route 10 (whippqny, NJ), who acknowledged the water intrusion but have refused to repair it under warranty or goodwill. Instead, they are pressuring me to file a personal insurance claim, even though the issue stems from a known factory defect. The vehicle has now been out of service for weeks, and I am driving a loaner vehicle while mold continues to worsen in mine. Lexus corporate stated that they "no longer goodwill" these repairs, despite the ongoing safety and hygiene risks. There has been no recall or warranty extension, and I believe other owners may be similarly affected by this unresolved defect. This is a serious safety issue due to the potential for mold-related health problems, interior air contamination, and possible electrical damage from long-term moisture. I urge NHTSA to investigate whether this hvac defect poses a broader consumer risk, and whether Lexus is avoiding its responsibilities to repair or disclose this issue to other drivers.

This car is a hybrid. It is 15mos. Old w/13500 miles. I've had two 12v battery failures which resulted in 1 time being locked out of car, and 1 time locked in.

3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard. Tried sending photos but it didn’t work.

The engine shuts off for a second while driving.

My car powers off while driving and then cuts back home within a second. It also has electrical issues the lights so flash during the night when you’re driving and then the front and shakes so bad that it shakes you just about off the road when you hit the brakes.

Battery completely dead. Unable to unlock doors, close windows during rain storms or start vehicle. No electrical power at all! dissatisfied.

The vehicle would not start. It is a known problem with this phev that if car is not used for a couple of days the 12v battery becomes depleted and the car cannot be started and all systems of the car are dead.

Put key into ignition port and heard and felt a klunk. Key was then freely moving and connecting to nothing inside the ignition chamber. So vehicle would not turn over at all. Had towed to town closer to home. And currently having towed to mechanic shop for further evaluation. The only symptom the car was having previously was a mysterious scratching sound coming from what sounded like the right side of the hood near the firewall. Took to mechanic and he drove the car and heard the sound but could not pin point it, said nothing was scrubbing the fan or anything else he could see. And to bring it back if it got worse. Never did we think it was the starter nor the ignition chamber. The only way to know now. . . . Is to replace it and see if that noise is still there. There were no other warnings. The danger in this is being stranded. Still needs to be evaluated by mechanic.

Low voltage warning, vehicle purchased new 3 months ago. Vehicle failed to start.

From what I have been reading on that year and model, there seems to be major issues with the invertors. Like many I was driving on the highway and the vehicle just quits. This put me and many others in a very dangerous situation and I could have been hit at high rates of speed. If as many people are having these issues, then Lexus needs to step up and recall this part before someone gets killed.

When I start to coast to come to a stop the engine will rev, even though the energy flow screen shows the gas engine is disengaged and running only on ev. The engine will rev, even with me using the brake. But the ev light is off and the rpms are rising. Eventually the ev light will come on and the gas engine will cut off and the vehicle will switch to ev mode. My mpg has dropped to 36. 2, so something is not right. When I was at the dealer for my 10k service, they told me this was the car "shedding" the extra energy, but the battery was not fully charged, so I'm perplexed and frustrated.

Battery has "sulfated" twice in 15 months of ownership. Lexus/dealer have replaced battery two times. Considered safety issue since battery could "die" at any time. Could be locked out of car with infant inside or if battery dies while driving, car could become immobile.

The power steering and hybrid system failed and vehicle completely stopped in middle of busy freeway with no prior warnings or issues before. The safety of my son and I, and others around me during the abrupt stop of the engine. I could not move out of way. The vehicle has been serviced for this exact issue during a recall campaign lasting from 2011 to 2014. Ten years later and it is still happening! there were no warning lamps or messages or symptoms prior to this failure. It just passed vehicle inspections for the year.

Brand new vehicle- 12volt battery failed after 5 weeks. Lexus initially stated battery fine. Then battery failed while in their possession- Lexus replaced battery. Few weeks later battery failed again. Lexus tested & replaced battery for second time - but battery kept draining & they were unable to repair after having vehicle at dealership for 3. 5 months.

For some unknown reason the car will suddenly display multiple warning lights, check engine, service needed, traction control off/inactive then the car will go into reduced engine power mode which prevents acceleration and causes the car to feel like it’s going to stall or shut off. This has happened several times on major high speed highways causing other cars to slam on their breaks, drive recklessly to avoid my failing car. My daughter has been in the car several times when this happened and it took everything in my power to not collide with another vehicle. We have taken the car to the Lexus dealership every time and they have tried to fix the car over a dozen times but it keeps happening. They don’t seem to know the issue or cause, trying several different solutions. How can a car manufacturer not know what is wrong with their own car not how to fix it? what am I supposed to do, just keep driving it and pray an accident never happens? there is no warning when this happens and no way to keep the car from swiftly decelerating or keep the car from using “minimal engine power” which I’m to,d is to protect the engine but I’m more worried about us. The date below is for the most recent incident.

Warning lights triggered snd certain electrical vehicle functions affected. Lexus plano dealer states that wiring is soy based and destroyed by rodents attracted to the wiring and chewing it with result that critical vehicle functions affected and lights, brakes, etc. May not work resulting in crash. Wanted more than $10,000 to rewire vehicle and refused to make repairs under vehicles’ warranty. Apparently common knowledge that Toyota and Lexus are using soy wiring that attract rodents and other animals to eat the wiring. I believe that crashes may be occurring because of chewed through soy wiring and misdiagnosed as driver error, brake, failure, fires, lights out, or other causes because no one is investigating wiring that caused crash. Wiring should be recalled as it poses death, injury, and property damage risks with manufacturers and dealers knowing of the defective wiring and of the risks but intentionally hiding the information, failing to warn, and then making huge profits from the expensive over-priced repairs that are unnecessary if proper wiring is used. We have dealer invoices and repair estimates snd other communications.

Mileage 3445, vehicle age 3. 5 months. Car located in home garage with doors unlocked. Car locked itself making entry impossible. All systems refused to open with “clicker” or mechanical key. Possibly battery issue. Four (4) different tow truck drivers over 4 days could not gain entry. Safety hazard as a child or disabled person could have been locked inside. Tow driver could not “pop” the door lock. Despite pulling up on the inside handle, the door would not open. Towed to dealer. Thus far dealer has no solution. Dealer said they are contacting Lexus. No warning lights, etc. Vehicle is a plug-in hybrid. Drive battery was at 100%.

The car started showing multiple error messages on the dash and then shut off while in operation, it would not restart without a service call and battery boost. This has happened multiple times. Online research shows this is a common issue with the hybrid models - the 12v battery doesn't get adequately charged, voltage drops and car ceases to work - even while mid drive on the road, this is extremely scary and dangerous.

I’ve approximately the last 45 thousand miles, Lexus dealers have replaced the brake actuator and other components of the brake system on this vehicle at least 6 times due to noise issues. Lexus has stated that this is not a safety issue, I have an open ticket with Lexus, but yesterday I had to slam on the brakes and did not get nearly the response that should have come right away. There are no warning lights, as far as I can tell the traction control didn’t engage, and eventually the car suddenly started breaking much harder, but it was very delayed l, and disproportionate with any additional force applied. Lexus knows the brake system is an issue in this model to the point where they are covering the system for 10 years or 150,000 miles, but to say that it isn’t a safety issue seems short-sighted. This system works in conjunction with the radar sensors adaptive cruise control, and I’ve had. This car has also had a number of seeming electrical issues, with every door lock actuator replaced at least once, some of them more than once, and the infotainment system shuts down and reboots randomly or freezes.

Wireless charger caused iphone 12 to overheat. Picked phone up from charger before it became to hot to handle. Dealership admits issue, "there has been a significant improvement in wireless charging in our cars over the past couple of years. The wireless charging on our earlier models do have connectivity issues and sometimes may even overheat, especially in iphone. This is a known issue with no resolution currently, unfortunately. I hope this helps. " if the dealership recognizes an issue with overheating, I suggest a recall before the charger or phone starts a fire.
