Traction control light came on while i was driving on 10/27/10 26 days after i purchased this new vehicle. then the service traction control message came on followed by the check engine light. while trying to get out of traffic and park,as i shifted from reverse to drive,the vehicle kept rolling backwards. the gear shift illumination was no longer hi-lighting what gear i was in. i had the vehicle towed to the dealership's service dept and they claim that they not only cannot duplicate the problem but that they cannot find any problem at all and expect me to pick up this vehicle and make payments for the next six years on it. when this incident occurred,my first monthly payment wasn't even due yet. my [xxx] year old son was in the vehicle with me and we could have been in an accident. gm and the dealership (bryner cheverolet) refuse to give me a replacement vehicle or return my down-payment. they actually,expect me to put my life at risk to prove to them that this incident really occurred. under the lemon law,i am required to give them 3 chances to fix the problem. how can i do this if they cannot find the problem to fix. also am i supposed to put myself and others in danger to prove that there is a problem? *tr parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
