One thing to note: The law requires that the manufacturer has the burden of proof with respects to failures caused by aftermarket parts. In other words, they have to prove, beyond a shadow of a doubt, that the aftermarket part caused the failure. This is despite any bulletins the manufacturers issue regaring warranty claims and the presence of aftermarket parts.

This stems from a test of the law where a vehicle was modified and a failure occurred. It was under a class action suit some years ago. The manufacturer claimed the failure was due to the part installed. Further, it was noted that the part was installed directly to OEM structures. Testing ensued and it was found that the OEM part that failed had an inherent defect and the failure was not caused by the aftermarket part.

So, don't take what the stealer service department says at face value when they deny a warranty claim because of aftermarket parts. Also, it's ridiculous to have them say your piston connecting rod broke because you installed a swaybar. But, they will try.

Beware!
