Example complaints

Brakes: “The emergency assistance brake system was activated and it reduced speed when vehicle was stopped ahead of me but would not respond to my braking. My vehicle slid into other vehicle at 6.8 MPH (see attached report). I tried to apply more pressure to brakes but the vehicle did not respond to my brake pressurei was proceeding straight on city road”

NHTSA complaint #11162098, filed 2018-12, 6,847 miles

Fuel system: “Driving on highway, my vehicle stalled when I hit gas pedal, then it resumed normal speed. This has happen many times, but seems to be more noticeable now. I don't feel safe driving this vehicle”

NHTSA complaint #11386758, filed 2021-01, 32,000 miles

Other or unknown: “I when to a car wash facility and the ics sensor when crazy!!! (flashing the warning light). Now my car giving me a ics malfunction. The automatic braking don't work and the parking assistance neither. I believe this is a manufacturing problem due same car model and year experience the same but it has different VIN so there is not a recall for my VIN.”

NHTSA complaint #11406205, filed 2021-04, 57,000 miles

Engine: “When accelerating hear a loud groaning noise and feel a hesitation in the gas accelerator pedal. Have brought to the dealer 3 times, as it seems to be getting worse. Dealer acknowledges their is an issue, but says will not fix because their is no recall. They said will notify us if/when Lexus has a remedy. Apparently this is happening on 2016 & 2017 models. I am worried that my car is just going to lose power when accelerating as it seems to be getting worse and louder groaning noise. This happens first thing in the morning when the car is cold and accelerating between 0 to 20 MPH.”
