2019 Lexus RX: check engine light

Filed Nov 26, 2024 · Electrical, Engine · FL

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.

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.

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.
