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 consumer stated the vehicle continued to have problems. He stated the truck would idle in a rough manner, and the check engine light illuminated. The consumer stated he checked the codes on the vehicle, and determined they were transmission related. The consumer went to another dealer, who diagnosed the problem as a wiring harness issue and some crimped seals from the first dealerships workmanship. The vehicle was properly repaired and returned to the consumer.
