Body problems of the 2015 GMC Sierra 1500

Truck started to make loud clunking noise when driving taken it to two shops and wrong parts were installed as stated below. Bought from a used car dealership and they sold it as is now with the wrong parts.

Bad paint used by manufacturers that causes frames to rust out.

N242490120 is applicable for 2022 models but my 2023 also had the same problem; the grille upper cover broke at the taps and detached from the grille structure.

Cross member holding file tank rusted through causing the fule tank to not be supported and shock mounts no longer support the shocks to frame causing shocks to bounce around with possibility to puncher fule tank or lines also rear cross member that holders electrical components rusts off excessive rust on top of fule tank causing a inability to make repairs without replacing fule tank in entirety.

Paint is peeling all over and I see there is a lawsuit for this for my truck. How will this be covered?.

Body paint delaminating. Also, difficulty sometimes stopping vehicle extra length required to stop.

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.

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 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!.

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 passenger side window was on fire and smoking. It filled car with smoke and shattered the window.

Under body coating is peeling on a brand new truck. Its rusting because the steel is completely exposed.

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.

Scratches and clear coat flaking from road debri. Lots of chips when washed after driving.

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.

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!.

Design flaw in cabin air filtration system leading to health hazard within the vehicle. On two occasions in my first 16 months of ownership, mice have entered the cowl air plenum area and built nests on top of and out of the cabin air filter material. Both times 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. Their only response was to establish their case number 711507394608. No further action was taken. So far, my dealer has continued to repair the damage and install new cabin filters. No attempt has been made to block or screen the openings. The truck is regularly garaged with two 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.
