Takata recall: per dealership, 8/12/16 unable to make appointment to fix the recall number #49152. They have no idea when the parts will be in. Says it could tke up to one year!!!! We were in an accident with this vehicle. The truck was sandwiched between two cars, the airbag did not deploy at 35 MPH., he was injured. After vehicle came back from bodyshop with $7000.00 worth of damage fixed, airbag light came on and has stayed on. We use this truck for our contracting business, so is it safe like GM recall letter states? I called GM back on July 1st, 2016, asked if there was a Takata recall on this truck, I was told no. I told them the airbag light was on so why not recall based on other 2007 trucks? Part 573 safety recall report given to the NHTSA by GM clearly shows that all 2007 GMC sierras were to be recalled in area b, which is where I live.. High humidity. …
Truck randomly doesnt start. No crank no start became more frequent and has now died at hwy speeds 3-4 times. Resulting in no power steering,no ABS, airbags become deactivated in a stall situation to my knowledge. Making it very hard to control the truck in order to get it off the hwy/roadway. Stabilitrak light, tire pressure light, traction control light all stay on and the most recent light is now the ABS light. Now it's to a the point of hardly starting at all. The key has recently became very hard to turn as well. Originally the door locks would cycle multiple times , and interior lights dash lights would all cycle at fast rate all at once. When this first happened I was always able to eventually get the truck to start a short time after. Engine power reduced is another specific warning that appears now that it's now dying while driving down the hwy. …
There seems to be a relay problem in the fuse box under the hood. The first problem happened about 3 months ago. The truck was parked. It had no power. It would not turn over and had no instrument panel. Checked fuse bank and swapped relays around for the start relay. After swapping around a couple of times, it cranked. It ran OK for three months. Next problem occurred with my wife driving. With no warning it lost power and died. It would not turn over. After trial and error, I swapped around relays for the crank & run relay. It started. Note, I did not replace any relays. I just swapped the out with other relays. When swapping relays, the other functions worked as well. This second time was very dangerous as my wife was driving down the road and it just died. I have no idea what to do about it with it working fine for the moment.
Tl contact owns a 2007 GMC Sierra 1500. While driving approximately 55 MPH, smoke began to engulf the vehicle.

I have taking the vehicle to the dealer, but, they never find anything wrong. On Saturday the car stop , in the middle of traffic, and this time it did not move at all. The truck would not move, and I was trying to make a right, but I was stuck. I was worried that someone could crush from the back, because they could not pass, there was a man that came and push my truck to get out of the street .and now I am concerned for the safety of my daughter and me. This vehicle has giving me many problems, but the dealer never seems to find anything wrong with the vehicle. I had some items installed by them. One was a dvd player, it cost 2,300.

The issue is with the battery cables and attachment to the frame and fuse panels. Affects a wide variety of GM and Chevy models, and should definitely have a recall, as this causes a very dangerous situation. What happens is : 1. Truck will be running fine, as it should. Intermittently, without warning will start having door locks go up and down, along with check engine lights, gauge cluster resetting and complete power loss to the engine and components (power steering, brakes, etc.) 2. Upon shutting off engine experiencing full power loss. …

One of the electrically powered, folding external mirror assemblies became inoperable on my 2007 GMC Sierra 1500 pickup truck which LED to the entire mirror assembly becoming loose. The result was that the mirror assembly will slightly move back and forth while driving, causing the driver to erroneously sense movement of his vehicle or erroneous movement of an adjacent vehicle. This false sensing of vehicle movement is very distracting, causing a driver to lose focus on the road and to lose focus on the operation of his vehicle. The condition is distracting enough that it May, in some drivers, induce vertigo which could lead to catastrophic results. ## VIN failed ##
In moderate traffic, I was traveling south on germantown pkwy. At a traffic signal, the light changed to red and I stopped the vehicle. After a few moments at a dead stop , I noticed the speedometer jumping from 0 to 10 and then higher.with no indication whatsoever from instrumentation, the engine stalled. There were no indicator signals at all. I was able to restart the engine after placing the shift lever in park and turning the key. I then contacted on star, and reported the incident and asked for a diagnostic. They reported "an ignition problem" and said I should schedule an appt with a dealer.
