It can’t get any worse for this 2020 GMC Sierra Denali truck owner.
Kevin Albright shared his frustration in a post that echoed the sentiments of countless others on the 2019 – 2025 Chevy Silverado & GMC Sierra Owners Facebook page. He says,
“I can’t believe that my 2020 GMC Sierra Denali’s white paint is just peeling off like wallpaper. What’s up with this GM?”
“I tried a wrap, and it made it worse. The passenger side wasn’t even doing it, then I went to adjust the wrap, and it just pulled the paint right off.”
“I tried taking the problem to GM, but they don’t care. So now I’m out of pocket with it.”
“Is anyone else having this issue? 2020 Denali! Gotta love it.”
When High-End Trucks Have Low-End Paint
The fundamental expectation of a quality GMC Sierra truck remains the same: a solid, durable finish. But for a growing number of GMC and Chevrolet truck owners, that basic standard is not being met. I found Kevin’s startling complaint, and this isn’t an isolated incident.
“I can’t believe that my 2020 GMC Sierra Denali’s white paint is just peeling off like wallpaper. What’s up with this GM?”
The number of comments on Kevin’s post, as well as across various online forums, confirms that this is a widespread and deeply frustrating issue. Owners are reporting that the clear coat and paint on their otherwise new and expensive trucks are delaminating, bubbling, and flaking away. The problem is so severe that he described his paint as “just pulled the paint right off” when he attempted to adjust a vehicle wrap, leaving him with an even worse situation than before.
The primary cause of delamination on the clear coat of GM trucks is a flaw in the manufacturing process.
Industry experts and independent investigations suggest that the paint and clear coat are not bonding properly. A class-action lawsuit filed against GM for this issue on 2015-2019 models points to a similar problem, claiming the paint and clear coat were “chemically unable to bond.” This is a critical point of failure; without a proper bond, the top layers of paint are susceptible to peeling, particularly when exposed to environmental stressors such as heat, sunlight, and moisture.
The problem for owners is compounded by the fact that this is a factory defect, not a result of neglect or poor maintenance. One Reddit user noted on their own peeling 2016 GMC Denali that “the surface underneath is too smooth. It was never sanded down after Primer, so that the paint won’t stick.” This explains why Kevin’s attempts to fix the issue on his own or to seek help from the manufacturer have been fruitless.
“I tried taking the problem to GM, but they don’t care,” he lamented. “So now I’m out of pocket with it.” This sentiment highlights a crucial point: When a manufacturer defect manifests after the standard warranty period, customers are often left to foot the bill for expensive repairs, adding insult to injury.
This issue of peeling paint on the 2020 GMC Sierra and Chevy Silverado is particularly concerning for the longevity of these vehicles.
The paint job is more than just aesthetics; it is a critical layer of protection for the metal body panels beneath. Without it, the exposed surfaces are vulnerable to rust and corrosion, which can severely compromise the truck’s structural integrity and resale value. This raises serious questions about the long-term durability of the paint on modern GM trucks.

While GM has issued some Technical Service Bulletins (TSBs), they have often addressed different paint-related issues, such as peeling frame wax coatings on some trucks from the same model years. The lack of a comprehensive solution or a recall specifically for paint delamination leaves owners in a state of uncertainty.
Many owners are searching for answers, using phrases like what is causing the peeling paint on my 2020 GMC Sierra Denali or GMC Sierra paint delamination lawsuit. They want to know if they can expect a permanent fix and if GM will offer any financial assistance for the thousands of dollars in repairs.
This defective paint issue is not just a cosmetic flaw; it is a significant defect that affects the value and durability of a major investment. Owners are finding themselves in a difficult position, having to deal with a problem that is clearly a result of a manufacturing error, but receiving little to no support from the company.
Where Is GM?
As Kevin put it, “Is anyone else having this issue? 2020 Denali! Gotta love it.” This sarcastic final line underscores a deep sense of betrayal among brand loyalists who feel abandoned by the automaker.
For owners of these trucks, discovering a peeling paint problem after the warranty has expired is an especially bitter pill to swallow. They are now asking questions like Is peeling paint on my 2020 GMC Sierra a warranty issue and What should I do when GMC won’t fix peeling paint? It raises a critical question about the quality control standards at the assembly line.
GMC Sierra and Chevrolet Silverado owners are actively seeking information on GM Technical Service Bulletin: Peeling Paint 2020 Silverado Sierra.
Ultimately, this is a matter of corporate responsibility.
The report by Kevin Albright and the numerous others who have spoken out is not just a complaint; it is a call for accountability. The issue, which is clearly documented across multiple forums and even in class-action lawsuits, suggests a systemic problem rather than isolated incidents.
Conclusion:
Owners are seeking a definitive answer from GM and a promise that the company will stand behind its product, especially for a defect that could compromise the vehicle’s long-term integrity. The search term’ GM paint defect’ on 2020 GMC and Chevy trucks is a testament to the fact that customers are seeking official recognition of this widespread problem.
The silence from GM on this matter is not a viable strategy.
Customers are increasingly turning to online communities for support and information, and the collective voice is growing louder. General Motors must address the concerns of these truck owners with transparency and a clear path to resolution, rather than forcing them to bear the cost of a manufacturer’s oversight. This issue could tarnish the reputation of what are otherwise well-regarded and popular trucks.
