well i've had a few issues with my car one was the plenum had bubbles on it, the
ICC had a failing display, and then my alternator died, my car was modded and went in modded and all were done under warranty, i've done exhaust, underdrives, tuning, themostat lowering etc etc, they tried it on me that my car was modded therefor the warranty wouldn't apply, but I calmly pointed out that everything I've done, their performce shop right next door does to brand new cars, the service guy then shut up and ok'd my warranty claims......
