Brake lights stay on. Due to brake lights staying on cruise control is disabled. Vehicle brake opertation is doing the opposite, when in motion stay on and when slowing down or stopped brake lights turn off. Called GMC and informed there is a recall for the same year but for the Chevy Malibu. Took vehicle in for repair to repair and paid to have the body control module replaced on 02/15/2016, almost 7 months later the issue has returned. Attempted to have dealership that replaced part look at but told there is only a 12,000 mile or 12 month warranty and vehicle has reached over the 12,000 so no longer under warranty. We were also informed the was only a "temporary fix, and the BCM doesn't fix the breaks." Dealership claims the second part that needed to be replaced, which we declined, would have permanently fix the issue. Part had already been purchased at $10 and was going to be charged by dealership $150 for them to provide and install. Called GMC customer service for assistance to correct this safety issue. GMC called to inform us that as a courtesy and the approval by the managers at dealership, will be able to give a $2000 voucher towards a new vehicle or used. Called days later as voucher did not come through via email and informed unfortunately voucher as the vehicle must be under 100,000 mile for trade in. Per GMC customer service at this time unable to resolve correcting the safety issue with body module control and it would be the expense of customer to replace again after its been replaced a little over 7 months ago. Very frustrated as driver of the vehicle is 8 months pregnant and due to break lights not working may get into an accident. We were not informed this would only be a temp fix.

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 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 Sierra were to be recalled in area B, which is where I live.. high humidity. Memo was submitted May 27th, 2016. I just got my recall letter yesterday, August 11th. When I called GM to complain about that, and ask why the delay, I was hung up on. I want justice for airbags that do not deploy when they should.. what about we folk? there are many of us.the airbag light is still on< and now there are no parts to fix the problem. Our mechanic says when the light is on, the bags will not work. Great. No rental car from GM and no way to fix the problem. Should we not go to work" I doubt enterprise would like a contractor to use their rental truck as a "real" work truck like we do. Hence the problem.

The contact owns a 2007 GMC Sierra 1500. The contact stated that while driving at various speeds, the traction control warning light illuminated, the internal/external lights independently flashed on/off and the door locks independently locked and unlocked. In addition, the speedometer gauge would fluctuate from 30 to 50 mph. The vehicle was taken to the dealer, who was unable to determine the failure. The manufacturer was not made aware of the failure. The failure mileage was unavailable.

Will happen intermittently, as described by other GMC owners. See similar issue with other owners at this address: www.GM-trucks.com/forums/topic/129454-my-fix-on-my-Silverado-electrical-problem/?hl=stalling see also: NHTSA reference #10036550 tsb reference #pit-4730A vehicle is unmodified. 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. Cannot crank engine until power has been restored by popping hood and wiggling battery terminal cables. The reason why this is dangerous and should have an immediate recall, is first, when this happened I was traveling at 80mph. The vehicle completely shut off, causing me to have to guide to the side of the road without the ability to use blinker, power steering, or power brakes. I have communication with other GM owners of the same year range, but affecting multiple GM and Chevy models. (one is 2009 Yukon, describing the same issues.) I know that this complaint has been issued by other people as well. It is time for action.

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.

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 ##

I sent complaint to dealer the first month about.truck has 55,000 mileage verable and brought complaints to dealer.this complaint happens thus the time I owned truck. Truck is now at dealers trying to be safe for highway use again, I am afraid that with all the plastic burning smell from air vent, truck will go on fire!

The contact owns a 2007 GMC Sierra denali. The contact stated the vehicle was equipped with a heated washer fluid module. The contact received notification of NHTSA campaign id number: 10V240000 (electrical system) pertaining to the system. The manufacturer advised that the module would need to be removed to prevent a possible fire from occurring in the vehicle. The contact stated he did not want the module removed from his vehicle because it was one of the determining factors in purchasing the vehicle due to the climate in his area. The manufacturer was contacted and informed him there was nothing they could do for to assist him. The failure and current mileages were 54,000.

The contact owns a 2007 GMC Sierra 1500. While driving approximately 55 mph, smoke began to engulf the vehicle. Upon further inspection, the contact noticed that the wiring melted on the instrument panel from an unknown cause. The dealer stated that the wiring harness and resistor for the blower motor needed to be replaced. The manufacturer stated that because the vehicle exceeded its warranty, they would not assume financial responsibility for the repair. The failure and current mileages were 40,000.

I have a 2007 Sierra, which has been giving me problems since it was pur chased. It has stop in the middle of the traffic when I was driving. It has done this 4 times since I purchased 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. And they said that it was my fault so they did not fix it. And that was 3 moths after the installation of the dvd by them. And the battery die on the truck 4 months after it was purchased. That was the only thing they change. I hope that I can be helped, I feel very insecure in this vehicle. I'm happy that I did not get into a major accident because of all these problems. Thank you.

The contact owns a 2007 GMC Sierra 1500. While driving 80 mph in the rain, the circuit breaker box fell off the vehicle and landed behind the brake pedal. The contact had to stop the vehicle with the emergency brake. He feels that this is a safety issue because components of the dashboard should be more securely attached to the vehicle. He also feels that a serious crash could have occurred with the circuit box top falling behind the brake and firewall. The current and failure mileages were 1,700. Updated 09/10/08.
