GM is making it more expensive to repair your car:
Buying car parts online or other aftermarket places, and doing the work yourself can save you some money over taking your car to the garage. But if your vehicle was manufactured by GM, this automaker is clamping down on what parts you're actually allowed to use for certain repairs. If your car needs collision repairs involving the Advanced Driver Assistance Systems (ADAS), you must now only use new GM Genuine Parts.
For your next collision repair, you don't have the option of using a cheaper aftermarket or used part when an ADAS component needs to be replaced. This includes the cameras, radar units, sensors, control modules, wiring, brackets, and the mounting hardware. You also cannot use recycled, salvaged, reconditioned, or remanufactured parts, as previous exposure to damage could affect reliability, calibration, and safety according to GM.
And, GM warns that accessories or modifications, like protective films and covers, stickers, window tint, magnets, hood protectors, light bars, cargo racks, and more, can interfere with ADAS operation. Even non-GM suspension, steering, wheels, tires, lift or lowering kits, and other modifications can also create problems. Any modification that alters ride height, alignment, or handling are also a problem with GM.
Welcome to the new world of trying to force us into dealerships and to buy parts from them only! Not cool!
