What owners report most
Electrical system
“I was pulling into a parking space at a gas station and the vehicle took off at a fast speed and I could not stop the vehicle, the “parking assist light came in saying parking assist malfunction, I tried braking and nothing, the car kept going I hit something then it stop as I put the gear in park, the passenger electrical window won’t operate from the driver side, Lexus refused to take responsibility of an electrical problem occurred as the vehicle malfunctioned, at the shop they claimed nothing was wrong, with breaks or no electrical problem, there is something wrong with a part that causes difficulty getting the tire off and in turn damaging the tire , this was told to me be a auto repair shop, Lexus did nothing to take responsibility nor did they treat me well, as if I just decided to ram my car into something, I later read other reports where this vehicle had same problem with the vehicle just taking off and driver unable to stop the vehicle , I only had the car for about 4 months, and theirs all happened, I was afraid to drive it for awhile, but they wouldn’t even swap the car out for another”
Service brakes
“While traveling at freeway speeds the vehicle's emergency braking system activated without the operator initiating the system resulting in rear wheels locking up, causing the vehicle to go into a rear wheel skid.”
Forward collision avoidance
“The brakes failed, and I could not stop or control the car. How was your safety or the safety of others put at risk? The car nose-dived off the highway onto the on-ramp, I was with my brother and we could have died, and his back is broken, and my face is messed up. Scared to drive been crying every day the front airbags did not come out Has the problem been reproduced or confirmed by a dealer or independent service center? waiting on the insurance to review Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? By Police and Tow Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes, a same concern when driving in rain, or any time the road is not dry the car will slide, I have no control over the back of the car it slides often and i will have to correct it”
