Additional Information: Please see NHTSA Recall #N212332040 After our own investigation we have found a recall report for the same year make and model for the same issue of the fuel pump power control module. Our VIN was not included in this recall but has the exact issue and year as the recall. This is very dangerous to have these vehicles driving around without the owners knowledge of the potential FATAL Danger.

Vehicle without any warning quit running, had to be towed, 19,400 miles on vehicle. could have had a wreck since I was on a heavily traveled 4 lane highway. Dealer Heyward Allen in Athens Ga. determined that it was the fuel pump and is on national backorder. This would tell me that there are other vehicles with this issue. There was another recall for these types of vehicles that could have also included this one N212332040. GMC could not answer why my vehicle was not included in the recall. GMC has of today done nothing about this issue except to say that the NHTSA issued recalls and they did not. Would not even take responsibility for manufacturing the part.

The suv shown safety message, it was diagnosed with airbag not deployed. This is very important specially for the rear backseat. GMC doesn’t want to be responsible and makes customer pay.

Car lost power while driving at high speed. Luckily was able to coast to the side of a busy controlled access highway. This was the second time for this to happen while driving, first was on a surface road driving at lower speeds. Very first instance was trouble staring the car. This all took place over a month and half. Dealer could never replacate while the had the card the first time. They are saying now that this is due to a failed Fuel Pump Power Control Module, which there has been a recall on but my VIN was not in the recall. There were no warning light that come on before or when this happened. After multiple time trying to start the car the check engine light would come on.

My family and I were on a road trip to go camping. We were approximately 30 minutes out of town when the engine blew. Lost all electronics and had to drive off to the side of the road. GM roadside would not tow it back to my dealer of choice even though it was approximately the same distance driving it to another state. The dealer in bullhead city, Arizona, installed a new engine and after 10 minutes of running, the new engine seized as well. My vehicle has been down for over 30 days and I still do not have it back. GM is having issues with the 6.2L engines and I have tried to have it repurchased by GM to no avail. What happens when we eventually get this vehicle back, the engine blows and my wife is in traffic as she uses this vehicle as a daily commuter and gets into an accident because the vehicles engine blows again?
