General Motors passenger vehicle bumpers are designed in order to withstand a collision into a fixed barrier at (8 km\h) 5 mph. After absorbing the energy of the collision, the energy absorbers rebound to 80 to 90 percent of their original position. The energy absorbing capabilities of the front and rear bumper systems are achieved through a honey comb or foam type structure in each bumper.

The front and rear bumper fascias are made of urethane, which will withstand a minor impact and return to the original shape.

For bumper and bumper fascia repair or refinishing, refer to General Plastic Repair in Plastic Panel Information and Repair.

Use care near theft deterrent labels. For more information on theft deterrent labels, refer to Anti-Theft Labeling in General Information.

If the bumper does not return to the original form after a collision, the following components may need replacement:

    • The bumper fascia
    • The energy absorber
    • The impact bar
