- ADAS components must be repaired and calibrated using GM’s own procedures.
- Any ADAS-related part that isn’t new and genuine is “strictly prohibited” by GM.
- Suspension and steering modifications can also throw off how ADAS works.
GM has issued a stern warning to anyone considering repairing one of its ADAS features with anything other than new, genuine parts: do it, and you risk compromising the reliability and safety of those systems.
In a collision position statement issued in late July and spotted by Autobodynews, the automaker said only genuine GM parts belong in collision repairs. That covers radars, cameras, sensors, control modules, wiring, brackets, and mounting hardware.

Not only does the company state that components that are salvaged, recycled, reconditioned, remanufactured, aftermarket, or from the secondary market are not approved for use, but they are “strictly prohibited” from being used when repairing Chevrolet, Buick, GMC, and Cadillac models.
The reasoning is that non-genuine and used hardware may not have been built or handled correctly, which can hurt reliability and calibration. GM also warns that protective films, wraps, window tint, hood protectors, bicycle racks, cargo racks, lightbars, and roof cargo carriers can all interfere with how an ADAS system behaves. The company sells several of those items as factory accessories, which makes the warning a slightly awkward one to issue.
In addition, upgrades such as lowering kits, non-genuine lift kits, and any other modifications to a vehicle’s suspension, steering, wheels, and tires that affect ride height and alignment angles may also adversely affect an ADAS system’s performance.
A dizzying array of features is included within GM’s ADAS system. These include adaptive cruise control, forward collision assist, lane keep assist, lane departure warning, front pedestrian braking, head-up display, rear cross traffic alert, automatic parking assist, surround vision, Super Cruise, and hands-on lane centering assist. Beyond the parts requirement, GM wants its approved repair and calibration procedures followed to the letter.
