2012 Chevrolet Colorado. Consumer writes in regards to transmission issues. The consumer stated the vehicle would not start. The vehicle was towed to the dealer. When the consumer called the dealer a couple of days later, he was informed the issue was the transmission. The next week, the consumer was informed, the parts replaced in the transmission were not issue, and after further investigation, the issue was a loose timing chain tensioner. Later in the week, he was informed that the engine was damaged and there may have been a spun bearing that caused the issues. The consumer was then informed the engine needed to replaced, but it would take couple of days to get an approval for the replacement. The authorization finally came through and the dealer proceeded to replace the engine the following week. The consumer was told he could pick the vehicle up on June 1st. However, they wanted to put some additional miles on the truck to confirm everything was in specification. When the consumer arrived at the dealer, he was informed the vehicle overheated and had to be towed back to the dealership. The dealer had the vehicle for two weeks.

The 2009 model Chevrolet Colorado will not start when I turn the key in the ignition switch. The incident date and mileage may not be correct, however when I first began experiencing this problem, I would always call on-star and they would run a diagnostic check while the car wasn't operating properly. The diagnostic would always come back " normal". I learned that if I waited 5-9 minutes, the vehicle would start as if nothing were wrong. The " no-start " has become more frequent. I have been in contact with gm recently concerning the "no start" problem and an "air bag" sensor light that has recurred after the first dealership "supposedly repaired" and charged almost $300 ( the billing statement read " reset sensors" and the dealership refused to elaborate on the type of sensors that were "reset" ). Gm made arrangements for a second dealership to look at the "air bag" issue, but refused to address the "no-start" issue. The driver's side seat- belt pretensioner was replaced for $303. The repairman related the pretensioner to the "air bag" sensor light. I inquired about reimbursement for repairs and recalls on the 2009 Colorado and was rudely informed that reimbursements would be" denied". After giving two scenarios of me being in an injury and fatal accident related to the "no-start" issue, I was told by the gm representative that "we will deal with it, then!". I asked if there had been any recalls for ignition switches on gm products and was told "yes, but there was no open recall on my particular vehicle" . I researched recalls on the 2009 Chevrolet Colorado and discovered a fuel system control module recall dated may 6, 2009 before I purchased my vehicle in July 2009 (NHTSA campaign # 09v-154), and the product safety recall bulletin no. 08411 includes VIN numbers 98104802 through 98123134. My VIN number, is included in this range. Please help !.
