Owner report 11660460 · 2025-05-12 (May 12, 2025)
Two (2) times (6-weeks apart) while on Freeway, loss of power and some shaking occurred, making it difficult to bring vehicle to a safe stop. Vehicle has only 80k miles, low for a Lexus brand.

Failure in both circumstances was related to fuel injectors, cylinder no. 4 at first then second failure six weeks later was on cylinder no. 2, the fuel pump appears to be a known problem on these cars and many Toyota/Lexus models. Low fuel pressure is s…

Owner report 11501379 · 2023-01-11 (January 11, 2023)
Bridgestone 235/55 R18. I was driving in the far left Lane on the interstate going 65mph. The tire pressure warning came on. The vehicle seemed too shaky to continue on. I attempted to merge right to get off on the next exit and the vehicle began to shake violently. Before I could exit safely the tire shredded with several loud pops in the 3rd lane of traffic before I was able to merge to the exit. I had to stop on the side of the interstate. I was strong enough to keep control of the vehicle by gripping the steering wheel. The safety of myself…

My car is going into limp mode/ reduced power and I am having misfires on cylinders 3 and 4. I’ve replaced my fuel injectors, spark plugs and catalytic converter.
