There are 4 owner-reported electrical system complaints for the 2017 Lexus RXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard. Tried sending photos but it didn’t work.
The car stalls while I'm driving, and it almost caused a traffic. Accident, I have been trying to contact my local lexus dealer and they keep hanging up the phone when I try to call and make appointments
