2019 LEXUS RX Fuel/propulsion System Problems

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.

Unintended acceleration causing accident March 2, 2023. Low speed frontal collision avoidance assist did not engage causing accident June 11, 2024. August 2023 I agreed to video and Lexus is not providing video of accident June 11th, 2024! Recall on fuel pump and software replaced but still BAD. Radio off. Heard cybercrimes of communications systems for video game data by Meta.

My vehicle has an intermittent check engine light along with an ICS malfunction code that pops up on the dashboard. The car doesn’t want to turn on after every gas fill up. After taking my car to a couple of independent shops, they determined that the issue with the car was the high pressure fuel pump. The suggested, I take it to the dealer as there was TSB bulletin on it. Furthermore I still had the letter from Lexus stating the issue. The local dealership refused to do the work and suggested other work after charging a huge amount for the car inspection. Lexus Corp wouldn’t help on the matter. There are 4 other complaints on this same issue and the dealers and the Plexus Corp are getting away with not calling this an actual recall because the government hasn’t stepped in.

Codes P219C & P0301 have continuously came on , these lights MIL have made the vehicle go from AWD to 2 wheel drive while in motion. [XXX] vehicle was taken to Bay Ridge Lexus. In brooklyn NY. They over looked this issue and stated it was something else. This has been confirmed via multiple diagnostics machines. Lexus of Edison has also decided not to cover this repair under warranty . The danger of going from 4 wheel drive into 2 wheel drive while in motion is extremely dangerous . These warning lights/MIL once activated has also caused the vehicles sonar to fail cause a serious safety issue. My vehicle is available to be inspected as needed.

While vehicle was being driven into the garage the vehicle suddenly accelerated on it own without driver pushing on gas pedal. Vehicles automatic emergency braking did not engage. Vehicle then struck steel shelving and wooden cupboards causing considerable damage to vehicle. The body shop where the vehicle was taken for repair experienced the same surging phenomena when they moved the vehicle. There were no system warning lamps visible prior to the episode. The vehicle has not been inspected by Lexus.

The accident happened on 12/28/22. At 8:50 am, I was picking up a friend and was leaving the parking lot. My friend got in and and then opened the door to lock it again . My foot was on the gas pedal trying to leave the parking lot. The car jumped and went to the opposite side. I turned the steering wheel to keep it from hitting an object but could not get any control on the car. The car kept accelerating and I had to put the car back into park to stop the car. The acceleration was so much that the car jumped the curb and stopped by a wall. The air bags opened up.

In heavy traffic the car stalled and by pumping the accelrator several times it activated..then at the stop light it did the same issue and heavy traffic was upon me blowing there horns..I carryed it to a lexus dealer and they could not determine the problem..I went online and found out that their is a recall on this vehicle..which was not taken care of by the car dealer before I purchased the vehicle in April 2021. Lives can be taken and I want this problem taken care of before it's our lives.

Vehicle has been reported before for similar problems. This time, no power, severe stumbling, lurching. Check engine light comes on along with warning indicators that the electrical systems have failed. Lexus notified again and vehicle will be towed to dealership. This car is dangerous and life threatening as we were in traffic with no power. Dealer did not notify us of any problems prior to sale but this car qualifies as a lemon under AZ law. Additionally, if other Lexus owners are having this problem, they should immediately stop using the vehicle and park it before someone gets injured/killed.

Car does not speed when gas pressed, noise and car shakes. Engine check light on and screen showed trac off. Saw something with engine power issue. Parked car and called Lexus emergency. Car at dealership and it is being inspected.

Vehicle stumbles and loses power when accelerating. Loss of power when passing. Both situations caused driver to abort action for fear of not having the power to enter the roadway or pass vehicles. Lexus dealership acknowledged the problem with this vehicle and said the fuel pump was replaced because of a recall. Problem continues to exist and is dangerous to driver and others. Dealer further recommended we “ change our driving habits “ to remediate the problem. Not acceptable.

While driving 65-70mph on the freeway, the car started dinging and one of the first messages that we saw was "pre-collision system malfunction" & "hybrid system malfuncion" followed by every other "system malfunction" and the gas pedal was no longer supplying gas to the car. We were in the fast lane and had to work over 3 or 4 lanes to get to the emergency lane/exit. Since we were at an exit, we took the exit and coasted as far as we could before the car came to a halt. Another car stopped to help us get completely off the road since we weren't fully in the emergency lane. After a few minutes we were able to crank the car and drive it a few miles to the dealership. We left the car at the dealership and they called the next day to inform us that the fuel pump had to be replaced. I did not find this vehicle to be part of any recall or lawsuit but several other Lexus models are part of a recall/lawsuit due to a problem with the Denso fuel pump. I'm not sure if my car has this same fuel pump. There were no warning lamps, messages or other symptoms of the problem prior to the failure.
