Voiding a warranty

[Dragracer]

I am an Independent Mechanical Inspector. I'm the guy an extended warranty company sends in to inspect your car if there's a claim from a repair shop. I can't speak about the factory warranty, but I can speak about extended warranties. If you read your extended warranty contract, there will be a clause in it stating something along the lines that if you modify the vehicle, they can deny coverage based on the modification. Example, if you install headers, intake, turbo, nitrous, etc., and have an engine or transmission failure, the company can deny coverage based on the modification. It you raise or lower the suspension, and have a suspension failure, or a trans or axle failure, the company can deny the claim. They cannot stop you from modifying your car, but they can deny coverage. I have seen manufacturers and dealers deny factory warranty coverage to a couple of heavily modified Mitsubishi's. One had a full cage, with racing seats, race type tires & wheels, and some mods to the turbo system. It was a street driven car with less than 12k on it. It had wiring issues, and the dealer, with the factory rep's blessing, told the owner, they would do no warranty work on his car. I was there for the first refusal of work. I have no idea what happened later.
