Sierra 1500

After months of purchasing my vehicle which is a Sierra denali my dashboard has cracked in half. The purge valve and the high pressure oil syndicator sensor has been changed about 5 times. When I put vehicle in my truck it won't start on its own the starter just keeps turning over to find out by that the sensor under the gas tank needs to be changed now. I heard that this was a known issue with this vehicle and that is why they changed the system on it, but my truck was never changed. The dealership acts like my complaints were senseless and after a year my warranty has ran out.

2010 gas leaking around fuel tank sending unit. Contacted dealer about recall non but it is common for this truck "?? fuel ? leaking ? fire? environmental hazard ?" GM replacement parts to replace rusted out sending unit $595 + labor @ $240 miles @52000. This is a safty and environmental hazzard and needs a recall before someone is dead!!!!!!!!!!!!

We were driving on a 2 lane highway going 60mph when all of a sudden the truck went to 20mph. The vehicle behind me almost rear ended me. I pulled over to the shoulder and saw the check engine light was on, and also there were other messages saying that traction control was out, vehicle stability was out, etc. I was a couple of miles away from the dealership so I called them. Luckily they were open on Saturday. I took it there and had the throttle body replaced. The truck has only 18,500 miles on it. The service man said there were no recalls or service bulletins for this problem. The little research I have done shows that many other owners have had this same problem.

The first time was Nov.2014 when the check engine light came on solid along with the traction control light engine power was reduced and the engine vibrated and would not go over 20 mph.I left the truck parked for 3 days and when cranked the truck all lights were off and the truck ran fine.once in Dec. 2014 and once in Jan.2015 the solid check engine light came on but the truck ran fine and after a few days went off. The first week of Feb. 2015 the check engine and traction control light came on engine power was reduced and engine vibration. I was able to drive slowly only to an independent mechanic that I normally go to because he was closer than the dealership and I wanted it check immediately since the warning lights were on.his codes showed the throttle body with sensor needed to be replaced.he stated he left the codes in even though the warning lights went off because he thought this work was covered under warranty.I immediately called the dealership and they wanted to make an appointment for the following week and when I told them all the warning lights had went off they stated it would probably be a waste of time to check on their computer. I told the dealership service dept. About how you don't know when this will happen and when it does you are basically stranded because the vehicle will barely move. The next week Feb.11, 2015 it happened again and all 3 times I was lucky I was not in alot of traffic or traveling at high speeds or on a steep grade.if I would have been there may have been a accident. I had to leave the truck in a parking lot and the next day took it back to the independent mechanic.I called the dealership and again they wanted to make an appointment and they stated the work was not covered under warranty so my mechanic came up with the same codes and fixed the problem.called GM and explained the unsafe situation and got no customer service.

Saturday, July 27, 2013, our 2010 GMC Sierra K1500 caught fire and was completely destroyed as my husband was driving on the interstate. As smoke began to fill the cab and the "check engine" light came on, he attempted to brake so that he could escape, but the brakes were gone, and the brake pedal went all the way to the floor. Imagine his terror as he realized that at age 65, he may have to jump out of the truck or be consumed by a fire. He was able to down-shift to slow the truck enough to use the emergency brake to get the truck stopped just in time to escape from the truck and get far enough away to avoid bodily injury as the truck and our belongings burned completely. We are gravely concerned that the truck, which was purchased three years ago this month, and had only 18,000 miles on it, clearly was a risk to our lives and the lives of others. We have three adult children and seven grandchildren & often had one or more of them with us as we traveled in this vehicle. Had we needed to unbuckle the babies from their car seats and/or assist the toddlers in getting out, the outcome may have been very different, and it haunts us to know that this could have been the case. All had ridden in this truck in the weeks preceding yesterday's fire. As my husband headed home to Montana at the completion of his travel to visit our children and grandchildren, he ascended, then descended "lookout pass" on I-90 at the Montana/Idaho border - a pass that is steep and very busy with summer vacation travel as well as consistent heavy semi-truck travel. The curves on lookout are treacherous: The rate of accidents and semi-truck rollovers on the curves is high without an extraordinary event such as a burning vehicle. If our truck had caught fire even three or four miles earlier as he was descending the pass, the outcome is almost unthinkable.
