Rear Bumper: Description and Operation

Door and Bumper Reinforcement Beams

The door and bumper reinforcement beams used on Acura TSX vehicles are made from a metal equivalent to high-strength steel.

If high-strength steel is heated, the strength of the steel is reduced. If high-strength steel is damaged, for example, in a collision, and the door and bumper reinforcement beams are bent, the beams may crack when attempting to straighten them. If a door beam is damaged, the whole door panel assembly must be replaced.
Front and rear bumper reinforcement beams are made of aluminum alloy.

For this reason, the door and bumper reinforcement beams should NEVER be repaired; they must be replaced if they are damaged.
