TL;DR: GM maintains an official position statement advising against aftermarket, salvage, recycled, or reconditioned parts in collision, structural, and system-dependent repairs on Chevrolet, Buick, GMC, and Cadillac vehicles. In mid-2026, GM strengthened that language further, stating it “does not support and strictly prohibits” the use of salvage, recycled or used, and non-Genuine aftermarket parts in these repairs, with added emphasis on ADAS sensors, windshields, and bumper fascias on ADAS-equipped vehicles. Damage tied to non-GM parts falls outside GM’s New Vehicle Limited Warranty and GM service plans. Jupiter Collision Center in Garland, a member of the GM Collision Repair Network, follows GM’s genuine-parts guidance on structural and safety-related repairs.
When a Chevrolet, Buick, GMC, or Cadillac goes into a body shop after a collision, where the replacement parts come from might not seem like a pressing question. But General Motors has a clear, published position on it: for collision, structural, and system-dependent repairs, GM advises using only genuine GM parts and GM-approved repair procedures.
What GM’s Position Statement Says
GM’s published collision repair position statement advises against the use of aftermarket, salvage, recycled or used, reconditioned, or other non-GM parts in collision, structural, or system-dependent repairs. In 2026, GM strengthened that language, stating that it “does not support and strictly prohibits” the use of salvage, recycled or used, or non-Genuine aftermarket parts on Chevrolet, Buick, GMC, and Cadillac vehicles. The updated guidance also calls out specific repair categories where this matters most, including advanced driver-assistance system (ADAS) components, windshield replacements, and bumper fascia repairs on ADAS-equipped vehicles.
GM’s reasoning is straightforward: the company designs, engineers, tests, and validates its own parts to meet specific safety, performance, and durability requirements. Aftermarket parts are produced without that oversight, so GM cannot confirm they meet the same standards, and the same logic applies to salvaged or recycled parts pulled from previously damaged vehicles.
Why It Matters for Structural and Safety Repairs
Modern GM vehicles use high-strength steels, aluminum alloys, and crumple zones engineered to manage crash energy in specific, tested ways. An aftermarket fender, hood, or structural panel can look similar to the original, but small differences in material thickness, tolerances, or fit can change how the vehicle behaves in a future collision.
ADAS sensors add another layer of complexity. Cameras and sensors built into bumpers, grilles, and windshields rely on precise geometry and material properties to function correctly. That’s part of why GM’s updated guidance specifically flags windshield and bumper fascia repairs on ADAS-equipped vehicles: even a correctly-fitting non-OE part can throw off calibration for automatic emergency braking, lane-keeping assistance, or blind-spot monitoring.
GM’s position statement also addresses supplemental restraint systems, including airbags and seatbelt pretensioners, and does not support the use of used, salvaged, or imitation parts in these safety-critical systems.
Warranty Consequences of Non-GM Parts
GM’s guidance has a direct warranty impact. Any damage, failure, or performance issue traced back to the installation or presence of non-GM parts, accessories, or modifications is not covered under GM’s New Vehicle Limited Warranty or GM service plans, and that exclusion can extend to related systems affected by the non-GM part, not just the part itself.
For owners, that means a repair that looks like it saved money upfront could end up costing more later if a warranty claim gets denied because of a non-GM part installed during a prior repair.
How This Applies at Jupiter Collision Center
Jupiter Collision Center in Garland is a member of the GM Collision Repair Network, which means it works from GM’s documented repair procedures and follows GM’s guidance on genuine parts for structural, safety-related, and system-dependent repairs. That matters most on repairs involving frame rails, pillars, ADAS sensors, or restraint systems, exactly the categories GM’s position statement addresses directly.
What Owners Can Do
If your GM vehicle needs collision repair, a few questions can help protect both your safety and your warranty:
- Ask the shop directly whether they plan to use genuine GM parts and GM-approved repair procedures.
- Request documentation showing the source and part numbers for every replacement component.
- Ask about pre- and post-repair diagnostic scans, especially on vehicles with ADAS features.
- Talk to both the repair shop and your insurer about warranty implications before repairs begin.
Texas law also gives vehicle owners the right to choose their own repair facility and the type of parts used, even if an insurer recommends a different shop or parts source.

Frequently Asked Questions
Why does GM advise against aftermarket parts for collision repairs?
GM designs, engineers, tests, and validates its own parts to meet specific safety, performance, and durability standards. Aftermarket, salvage, and recycled parts are produced without that oversight, so GM cannot confirm they meet the same requirements. GM’s position statement advises against these parts specifically for collision, structural, and system-dependent repairs, including areas involving ADAS sensors and restraint systems.
Can using aftermarket parts affect my GM vehicle’s warranty?
Yes. Any damage, failure, or performance issue tied to the installation or presence of non-GM parts is not covered under GM’s New Vehicle Limited Warranty or GM service plans, and that exclusion can extend to related systems affected by the part, not just the part itself.
Are aftermarket parts ever acceptable on a GM vehicle?
GM’s position statement draws a firm line around structural components, supplemental restraint systems like airbags and seatbelt pretensioners, and repairs involving ADAS sensors, windshields, or bumper fascias on ADAS-equipped vehicles. In these areas, GM advises using only genuine GM parts and approved repair procedures. For purely cosmetic work outside these safety-critical categories, GM’s guidance is less strict.
