I am submitting this complaint regarding a paint defect on my 2020 Buick Enclave. The passenger-side rear door has significant top-coat peeling and flaking, exposing the primer and metal underneath. This deterioration is not normal wear for a six-year-old vehicle that has been properly maintained and protected from environmental conditions. The pattern of peeling indicates a failure of the top coat or clear coat applied during manufacturing. The paint layers are separating prematurely, reducing corrosion protection and long-term durability. Exposed metal increases the risk of rust, structural weakening, and potential failure of the door panel, which may affect occupant safety in the event of a collision. I am aware that similar paint adhesion failures have been reported across multiple General Motors vehicles, and class-action lawsuits are currently pending alleging defective basecoat and clearcoat systems that cause premature peeling, bubbling, and flaking. The number of complaints suggests a broader manufacturing issue rather than isolated consumer misuse. Although my vehicle’s limited warranty has expired, the defect is clearly premature and manufacturing-related. A properly applied top coat should not fail this early, especially on a vehicle that has been routinely washed, waxed, and stored in normal conditions. I respectfully request that NHTSA review this issue and consider opening an investigation into paint top-coat failures on Buick and other GM vehicles. Premature paint failure affects corrosion resistance, vehicle longevity, and consumer value, and may compromise the safety of occupants and other drivers if corrosion spreads or structural integrity is reduced. I am willing to provide photographs, documentation, and maintenance records to support this complaint. Thank you for your attention to this matter and for your commitment to consumer safety and manufacturing accountability.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Buick Enclave verdict →
