After reaching the 100,000 mile mark, my Traverse ran rough, had slow acceleration, and sometimes low power. The mpg went down drastically from aprx 320 per tank to btwn 230-250. It was well maintained with routine oil changes, recently with synthetic oil due to the high mileage. I changed the spark plugs and air filter, which helped for a short time. It began revving at high rpms on the freeway and not shifting. After aprx five months of experiencing the symptoms periodically, the engine light finally came on and alerted there was a problem just over 108,000 miles. The code p0008 indicated a timing issue, resulting from either a stretched timing chain or bad tensioner. The light was off the next morning, but returned later the same day. I did not drive the Traverse for aprx two weeks in fear of the timing chain breaking. The day I was taking it to the dealer, I attempted to start it and blew the engine. The chevy mechanic confirmed it was a result of the timing chain. Doing research, there are several cases of the 3. 6l engine having problems with the premature failure of the timing chain stretching. I am just thankful I was not driving at the time it broke. I want to know why it took so long for the engine light to come on after experiencing the signs for months. Chevy had the same problem with the 2009 Traverse and extended the warranty to 120,000 miles. They need to do the same thing with the 2010's as well. The maintenance manual indicates the timing chain doesn't even need to be checked until 150,000.
