Does anyone have any experience with warranty issues due to a suspension lift. I'd like to hear from anyone with actual experience, .....does this "void" your warranty?
Essentially, the dealership must prove that your upgrade caused a particular part to fail for them to not repair your truck underwarranty. They can't say that because you installed an after market lift that your O2 sensor failed and they aren't fixing it. They have to PROVE that your lift broke the O2 sensor...
I've put a Magnaflow exhaust on my truck and just last month had my truck in for warranty repair and I did not get any grief about it.
