The contact took the vehicle to a certified mechanic who stated that the heater wires that had a connector that had burned the wires on both ends of the connector.

Low oil pressure light came on due to excessive oil consumption while driving. Engine burned 5 quarts of oil in under 3000 miles. 105K miles on 5.3 liter V8. Dealer said typical for this engine to have carbon buildup and needs new piston rings and pistons. Also driver side door lock actuator replaced and window switches.

All four power door lock actuators have failed. First three failed before reaching 30000 miles. Dealer advised they were not covered under warranty. I argued with them, by the time my truck had 50000 miles all four had failed and was told that the warranty expired at 36000 miles. This is a safety hazard and GM refuses to acknowledge the millions of vehicles affected by this issue. GM wants $300 per door to repair. I shouldn't have to pay them $1200 for something I paid for with the price of the truck.

My dashboard has several cracks exposing the electrical components within the dash. These cracks are in various places across the entire dash. I purchased this vehicle brand new and it is currently in excellent condition (with the exception of the dash) I am concerned that if the air bag were to be deployed the plastic dashboard would explode and expose my passengers or myself to additional hazards within the vehicle. I am also concerned that the electrical system in my dash board is now exposed to additional hazards due to the additional exposure to the sun. I am filing this incident with the hopes that it will help a recall to be issued. I noticed the first small crack in 2011. I have kept an eye on it over the years and as of today, there are exposed openings in the dash in several places. Until today, I thought that I might have just been unlucky, however after doing some research online, it is apparent that I am not alone, and this should be recalled under a manufacturers defect. Thank you for taking the time to file this report on my behalf. Feel free to email me with additional information as needed. Best regards.

My service man was pulling out of parking lot at store when air bags exploded and seat belts locked. He did not hit anything and was only going about 10 mph when this happened. Took to local dealer to see if they could fix it. They said yes, but we would have to pay for it. We could contact the manufacturer if necessary. The bill was $1413.89. (parts $798--labor $562.59 tax 48.19). We had to get it fixed as it is illegal to be on the road without seat belts (or air bags). We feel these are defective parts an D we should be reimbursed by the manufacturer.. this is an unsafe vehichle!!!! thanks

Jan 2015 the air bag light came on. Many complaints on this issue. Also June of 2015 the door locks started acting up. Passenger side will not lock/unlock now the driver door is acting up also... many complaints seen on both these concerns.

Power surge to electrical system... voltage meter will drop below 9 volts then the following occurs: Headlights flicker, radio shuts off, climate control shuts off, dash lights flicker, air bag light flashes, service air bag warning pops up, and truck stalls out. This is a dangerous situation while driving and if this is electrical may cause fire. This is intermittent and occurs at anytime for no particular reason regardless of weather/temperature.

3 of my 4 door lock actuators have failed. Both rear doors could not be locked or unlocked except manually from within the vehicle. Reaching over the seat to unlock a child's door in an emergency constitutes a safety hazard. In my opinion, GMC should step up an acknowledge and address this issue.

The three passenger doors failed to unlock simultaneously I understand a tsb has been sent to dealers. This seems to be a safety issue, and should require a recall.

Rear passenger door will only lock/unlock manually from the inside. I have been told the problem is a failed door lock actuator. It will not lock/unlock with power lock button or key fob and there is no keyhole except on drivers door. This is my second GMC vehicle that has had the same problem and after searching the internet this seems to be a fairly common problem and I am trying to figure out why it has not been recalled or GMC has not been forced to fix the problem. Wouldn't you consider a door that does not lock/unlock the intended way a safety issue?

On 04.12.2014 after going to the store, parked under the carport. The time was 10pm. While inside heard a pop sound around 10:15 pm. Went outside and the truck was on fire. Put truck in neutral and pushed it from under the carport, trying to save damage to the house. Fire dept came and put the fire out. The fire warped all the vinyl under the carport. Lucky it didn't catch the house on fire. The fire was worse on the passenger side of the vehicle.
