What can fail
A plastic protector covering a wire harness connector near the seat belt pre-tensioner can catch fire when the pre-tensioner activates, because the connector is too close to the hot combustion gases released.
What the fix does
The connector protector will be replaced with one designed to withstand the high temperature of the pre-tensioner's combustion gases.
