“when driving on the highway and i let up the gas the engine surges. this is an ongoing issue. makes me apply the brakes or take action scary. it happens all the time. took it to lexus and they say this is normal. to me it is a safety driving issue. it surges for some time with no gas applied.”
NHTSA complaint #11748178, filed 2026-07“I pulled onto a 4 lane divided highway and the car immediately went into limp mode, meaning the car would not go more than 1 MPH even with the gas pedal to the floor. I could NOT accelerate thus my safety was in danger, and I was almost hit by a tractor trailer truck. I pulled over to the side of road as best I could, then shut the engine off and restarted the engine. This apparently re-set some sort of engine control and then the car accelerated normally. The dealer applied an ECU update #24LC03. …”
NHTSA complaint #11618998, filed 2024-10“When driving, the car engine will randomly accelerate or race. The car does not physically go faster, but the engine revs at a high speed which is very scary. It will continue to accelerate while your foot is off the gas until you either press back down the gas pedal or come to a full stop. The car engine revs extremely loud making the driver feel like the car is going to keep going. I have had the car for 15 months and it continues to get WORSE. I have taken the car 3 times to the Lexus in Freehold NJ when I first bought it to fix this issue. …”
