To void a warranty the car manufacturer must PROVE that the modification caused the damage BUT Chrysler is noted for not following that portion of the Moss-Magnusson law and leaving it up to the consumer to sue them.
So the answer is yes it can void your warranty if they so choose. But that is up to the individual dealers discretion.
