Vehicle radiator has leak at 86k miles. There is known issue w/radiator and thermostat in this truck leading to TSB 15829 .

Radiator is leaking from the top with only 67,000 miles and transmission shifts hard and when u let off gas while driving about 55 the rpms go down to idle then start bouncing up 500rpms then back down. Then eventually will find a gear to go in.
I purchased my vehicle brand new in order to avoid unexpected expenses that one sometimes inquire when we purchase a used vehicle. However, the truck has given me nothing but mechanical issues I've head engine power loss problems, have gone through two air conditioner major issues, radiator gone bad, transmission go out and the most recent my roof started to leak. As I did more research I came to discover that I am not the only customer in this predicament there are several others. I'm reaching out to for assistance in regards to these matters, something has to be done GMC has to take responsibility for faulty vehicles if that's is the case. They only give the go around to customers like myself that on top of having a car payment we have to somehow pay high mechanical bills for issues that should not be accruing to new vehicles.

Radiator leak. Took truck to shop to find out why fluid leaking under truck. Upon inspection they found that the radiator had fractured. The repair people found that there had been a recall in 2014 for GMC sierra's, but ours wasn't listed. A radiator should not fail on a 3 1/2 year old vehicle. The specific special coverage # 15829 stated that cycling of the thermostat may result in stress fractures of the radiator. The repair people felt this was what happened. We were fortunate that we were in town and not traveling. We contacted GMC directly to file a complaint and they refused to do anything about it. Actually told us to file a complaint here. The resulting bill was $1,346. 07. $648. 17 in parts, $633. 45 in labor. Needless to say when it comes to buying another truck, this brand will not be on our list.
