Driving on connecter road between 2 freeways at 35-40 mph because of traffic. Suddenly the car veers to left on its own and hits concrete lane guiding wall damaging the left front of the car. Next tried to brake and they didn't work. Unable to steer the car it heads to the right and up on the rocks decorating of the road. Car goes another 25 or more feet before stopping due to rocks slowing down the car. The air-bags never deployed. Tried to contact SOS button but didn't work. Next contacted ONSTAR but they were no help and didn't show that an accident occurred and said call 911 which was done. Ever since the purchase of this EV car have been having trouble with it. The Emergency light (red car on dashboard) lit up and went to dealer who kept the car over a week. Green car worked for a while but occasionally turned red. Went to dealer again. Also, one day the steering wheel would not work until tried several time to restart the car. Dealer managed to break the steering wheel and repaired it. They also cracked the glass on the computer screen but denied they did it. Was planning to enact the Lemon Law on the car. Car now in repair shop. VELLOCITY COLLISION CENTER, 8765 LINDELL RD STE 100, LAS VEGAS, NV 89139 TEL 7028971320. Called GM Cadillac to inform them of information on accident. They said they would report this to the engineers there and report back to me. That was right after the accident but they have never tried to contact me.
