2019 Lexus RX Fuel 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.

Incident

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.

The acceleration was so much that the car jumped the curb and stopped by a wall. The air bags opened up.

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.

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.

Incident

Jun 17, 2021

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.
