Timing Tensioner problems of the 2010 Chevrolet Traverse

At approximately 92,000 miles I started getting error code p0008 on my 2010 chevy Traverse. The light would come on for a few days, then off for a day or two, until finally it just stayed on all of the time. The acceleration was very poor, and the gas mileage poor as well (compared to what it had previously been getting). I change my oil well before the meter in the car tells me to, usually before 5000 miles. Dealer said the timing chains stretched due to excessively dirty oil, but as stated earlier, I always changed the oil before the meter said to change the oil. Dealer replaced all tensioners and chains and resealed the front cover and refilled fluids. Gm covered 45% of cost even though vehicle was beyond warranty period. For a job that usually would cost about $2300, I paid $1336. I've read that others have had this problem with the 3. 6l v6 on the early model Traverses and other gms with the same engine. I believe that the reason that I got up to 92,000 miles is because I change my oil so regularly. The lack of acceleration was very unsafe for merging into traffic in denver, especially when it first began happening, unexpectedly. Vehicle was having trouble holding speed on hills on fast streets. If problem had gotten worse, vehicle would have not been drivable.

Tl the contact owns a 2010 Chevrolet Traverse. While driving approximately 30 mph, the vehicle lost power and the engine warning indicator illuminated. The contact was able to coast the vehicle to the side of the road and powered off the engine. The vehicle was restarted and was able to be driven to the contact's home. The vehicle was taken to eric von schledorn Chevrolet Buick (805 e green bay Ave, saukville, WI 53080, (262) 284-8000) where it was diagnosed that the timing chain and tensioner failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact took the vehicle back to the dealer where they contacted the manufacturer, but no assistance was offered. The approximate failure mileage was 101,847.
