The body has rust coming through on the lower body panels by the rear doors of a crew cab. Have to replace the AC condenser on a 2015 gmc Denali. Looks like GMC already knows there is an issues with this, but no recall on the 6.2L sierra denalis.
Radiator coolant leak, replacement Radiator with 11000 miles has begun to leak now.. Fuel injectors had to be replaced at 60000 miles. Blue Paint is peeling off in sheets
Paint is literally falling off in chunks. I baby my truck. Its mint condition, but I noticed the paint is not adhering to the primer in atleast 2 spots. After some rain, the paint just fell off the vehicle. GM refuses to assist in repairing. For the cost of the vehicle this is absolutely a major issue. This vehicle has no claims or previous body damage.
The vehicle always has a smell of dampness after a rain. Somehow water is getting into the vehicle. I have replaced the seal around the third-brake light which was thought to be the culprit, but no fix. The rear seat metal has rust on them from the damp. The driver's seat creaks when making turns. It is like it about to come apart. There should be a recall on this. People could get hurt if it happens. Le under the vehicle, I noticed that a body-mount is missing under the driver's side. This could be the reasons for the creaking. I am not sure!

I was driving down the road about a quarter mile from my house and the rear windshield on the driver side of my truck shattered. This is after I had them look at the same window for the defroster no longer seeming to be working. I've done research and seen the service bulletin N192265660, however my truck is not covered.
The pain on the GMC vehicle is defective it started to peel on its own under heavy rain! that has never occurred to any of my vehicles that I have owned for over 15 years! I have read there are many consumers complaining about this issue and nothing has been done the vehicle is less than 5 years old!
When at highway speeds of approximately 65+ mph the vehicle begins to vibrate or shake violently as if the rear end of the truck is about to fall out. It is bad enough to make you white knuckle the steering wheel cause you to swerve slightly
Remotely started the vehicle this morning and came out to find it smoke filled and the rear defrost on driver's side window was on fire and smoking. It filled car with smoke and shattered the window.
2015 GMC Sierra paint is blistering and peeling in the truck bed. Contacted GMC thru their app and the said to take to the dealership body shop. They took pictures and said it looks like the paint wasn't sticking to the primer. GMC said the truck was out of warranty. I could have someone repaint it at my own expense.
2015 GMC Sierra paint is blistering and peeling in truck bed. Never hauled anything in it. GMC dealership's body shop said factory paint didn't stick to the primer. Coming off in big pieces. Had truck for 3 1/2 years. Called GMC and GMC said out of warranty.
On several occasions all sounds from door chime, radio, onstar, etc. Have failed. Further the paint is beginning to blister from underneath. GM is denying both problems exist. GM says the paint issue is due to application of an extreme heat source. Arizona is hot, but not that hot. The sound issue is a safety hazard. The paint issue is typical corporate denial of legitimate claims.
The paint on my 2015 GMC Sierra is bubbling and peeling. After much research I found that this a consistent defect on my year vehicle. I contacted GMC and my dealer thorson GMC in pasadena California. The service manager at thorson GMC don schwartz had his body shop look at the paint on my truck and his response to me was that the paint on the chipping areas on my truck, both rear doors and the roof, was extremely thin and that he would try to get GMC to repaint my doors and roof at their expense. Two weeks later Mr. Schwartz calls me back and tells me that GMC is only willing to pay 40% of a $5000 paint repair and that I would have to pay $3140 if I wanted my chips repaired. I feel that this is ridiculous to have to pay for an obvious factory defect. Additionally I really feel for the thousands of people facing the same problem because GM didn't paint their vehicles correctly
This complaint is regarding excessive surface rust on not only the frame of my truck, but on critical engine component clamps in the engine bay. Any screw style hose clamp in my engine bay are rusted worse than my other 9 year old car with 102,000 miles on it. I wash my truck, including undercarriage, periodically throughout the winter to try and keep the salt off. My truck is a 2015 with 40,000 miles, and just recently, the rust had completely eaten through the lower radiator hose clamp causing all the engine coolant to leak out. I noticed the rest of the clamps within the engine bay to be in the same condition, along with the frame, and suspension components. It is clearly only a matter of time before they fail while I am driving, which could cause a failure of any system using one of these rusted clamps, such as the brake lines, power steering lines, oil lines, or transmission fluid lines.
Headlights are inadequate on high or low beams. It seems that the light is focused into two narrow beams in an effort to make up for the low lumen level of the led bulbs. These narrow beams don't light up enough of what is in front of you for night driving. I have to use my fog lamps to turn onto streets without street lights on the corner. The recirculating switch for the ventilation system will not even reduce the amount of outside air coming into the cabin, much less occlude it. Not good in 5 O:clock traffic or when your behind a diesel burner. The dealership acts like they are clueless and say everything is working as it should. After reading this form with so many headlight complaints, I asked if they had ever gotten any complaints like mine and they denied that they ever have; and they did it with a straight face!
The contact owns a 2015 GMC Sierra 1500. The contact stated that the frame rusted all over without warning. The dealer determined that it was surface rust, which was not covered under the warranty. The manufacturer was made aware of the failure and stated that surface rust was not covered by the warranty. The failure was not remedied. The failure mileage was approximately 24,000.
Design flaw in cabin air filtration system leading to health hazard within the vehicle. Mice have entered the cowl air plenum area and built nests on top of and out of the cabin air filter material. The filter has become saturated with mouse dander, feces and other materials. Eventually these contaminants work their way through the filter and an odor is noticed inside the vehicle. The mice are believed to enter this area through significant unscreened openings at the ends of a plastic cover over the plenum in the windshield wiper area under the hood. I have contacted GM with regard to this design flaw.. so far, my dealer has repair the damage and install new cabin filters at my expenses. Was told by dealer this was not covered under warranty no attempt has been made to block or screen the openings. The truck is regularly garaged with an other non-GM vehicles that do not have this problem. Individuals with respiratory conditions should be concerned about the significant plenum design flaw in these GM trucks.
