“1) a light in a dashboard came on saying check hybrid system , I took it to the Lexus dealer , they changed the non hybrid battery), charged me $350 for it and reset the computer. 2) a week after, the light started appearing again with the same message, the message appeared in the morning, in the way back home, coming out of the speedway , all the lights in the dashboard came off (brakes, engine, all of them) and I lost complete control of the car: no brakes, no steering, no nothing. I tried restarting the car again, it did, and the next day was driven to the dealer again. …”
