Purchased a used 2007 Chevrolet Equinox 6 hours after purchase, service airbags light, service t tire monitor system and check engine light came on in the instrument cluster and gags guage stopped working. .
On 1/28/13 I replaced the throttle body at gm certified dealer. Truck was diagnosed with code p2135 for failed throttle body and connector. While driving my 2007 chevy Equinox it displayed service traction control, service stabiltrak, engine power reducing and check engine light. On 7/5/13 I returned my truck back to the dealer. They diagnosed the truck again and replaced the part a second time. Now on 8/19/13 the truck was back at the dealer for third time and same issue. Dealer diagnosed my truck and could not find anything wrong at the time after I complained of same issue displayed on vehicle. 9/11/13 the service traction control/stabiltrak with check engine came on again. I took the truck back to the dealer and showed them video of the problem happening. This time they said they would diagnosed it and get to the bottom of my complaint. I called gm that day complaining of the same issue from last month. Gm reopened my case and said it would be transferred to another department level. The dealer called me later in the day and replaced the throttle body and connectors free of charge again. Every time while driving this truck I was traveling with my children and almost had accidents with this. This is unsafe and gm needs to have a recall on this part and model of truck. Some thing has to be done before it becomes fatal!!! hopefully this time the problem is corrected.
