GM Releases Position Statement on Replacements of Bumper/Fascia with Advanced Driver Assistance Systems
Replacing a damaged bumper/fascia on modern GM vehicles is no small matter. That’s because these parts now serve as home for sophisticated Advanced Driver Assistance Systems (ADAS) such as blind spot detection, park assist, collision alerts and automatic braking. Install a less-than adequate replacement or refinish these parts incorrectly, and the ADAS might not perform as designed. That could spell serious problems down the road.
GM issued a position statement in May 2018 on proper replacement of bumper/fascia with Advanced Driver Assistance Systems (www.genuinegmparts.com/for-professionals/position-statements).
GM Position Statement for Bumper/Fascia Replacement with Advanced Driver Assistance Systems (ADAS)
• General Motors DOES NOT APPROVE the use of aftermarket, reconditioned, or salvage Bumpers/Fascia on GM vehicles equipped with ADAS.
• Aftermarket, reconditioned or salvage Bumpers/Fascia may have different material specifications than what was designed, tested and validated for use with ADAS.
General Motors (GM) vehicles, systems and components are engineered, tested and manufactured to help protect vehicle occupants based upon both government mandated and internal corporate requirements relative to durability, Noise, Vibration and Harshness (NVH), occupant protection, and vehicle safety. The overall structural integrity of the vehicle is dependent on maintaining its inherent design specifications.
For General Motors, safety is the overriding priority. With the safety of our customers at the center of everything we do, we are limiting repairs to Bumpers/Fascia with Advanced Driver Assistance Systems (ADAS) to topcoat refinish only. Further, topcoat refinish material thickness of repaired ADAS Bumper Fascia systems must not exceed 13 mils in thickness. Any repairs such as gouges, tears or damage that require the use of substrate repair material or reinforcement tapes must be avoided.
Primer and topcoat refinish methods can be employed on ADAS equipped Bumper/Fascia systems, provided the total paint mil thickness on any portion of the Bumper/Fascia does not exceed 13 mils. It is necessary that a non-metallic paint film thickness tool be used post repair to ensure material film build on part does not exceed 13 mils in thickness.
Examples of ADAS technology include:
• Side Blind Zone Alert
• Front and Rear Park Assist
• Front and Reverse Automatic Braking
• Rear Cross Traffic Alert
• Adaptive Cruise Control
• Forward Collision Alert
Reconditioned Bumpers/Fascia available in the aftermarket may have been repaired using substrate repair “filler material” or reinforcement tapes and as such General Motors does not endorse the use of reconditioned ADAS Bumper/Fascia systems. Only Genuine GM ADAS Bumpers/Fascia and components are tested and validated as a safety system.
With the continued expansion and use of ADAS safety systems on GM vehicles, it is critically important to be aware of the proper service and replacement requirements for Bumper/Fascia systems. To help preserve the performance of repaired GM vehicles, GM publishes vehicle specific collision repair procedures and manufactures and sells Genuine GM Parts. Genuine GM Parts offer the same safety and performance as the parts originally installed on new Chevrolet, Buick, GMC and Cadillac vehicles.
Repairing a vehicle using Genuine GM Parts and following GM recommended repair procedures helps ensure that a vehicle is returned to pre-collision condition.
Using only Genuine GM replacement Bumper/Fascia parts can help ensure that the ADAS systems will perform as designed by General Motors. Doing so, upfront will also reduce cycle time. Aftermarket Bumper/Fascia assemblies may not have been designed, engineered, or tested to operate and perform as intended by GM. Non-original parts can be made of different material, or a slightly different configuration, which may cause the safety functionality to not perform as designed. The use of non-OEM safety and structural parts and components may compromise the overall crashworthiness and occupant safety of General Motors vehicles in a subsequent collision.

Safety is General Motors’ overriding priority. When repairing GM vehicles, it is important to follow GM OEM repair procedures and use Genuine GM Parts to help ensure that the ADAS systems will continue to perform as designed by General Motors.
