Gear, talked with a rep, what he said was beyond astonishing.... pretty much a round about way of saying if anything besides stock parts are on it you void the warranty which just does not sound right LOL...
"The answer I received from a mechanic or representative at the shop told me that if it damages the engine or another part, yes it will void the warranty. So I asked what if it is a aftermarket part? The individual then said "If it is not lexus's, then yes it can void the warranty then also."
All I have to say to what your dealer said is "You can fix Stupid".
Obviously the Lexus people at your dealership have not read, or have failed to fully comprehend the meaning of the Magnuson–Moss Warranty Act. What the rep and Mechanic said is partially true. The non-OEM part is not under Lexus warranty, but that is the only thing not under warranty. Buying a non-OEM oil filter or air cleaner will not void your power train warranty. With that being said, if you buy a really cheap oil filter or an air filter that has so much oil in it that it fouls you MAF (Mass Air Flow) sensor, and it hurts your engine then that is an example how a non-OEM part can void your warranty. It is an example of cause and effect. Always buy quality name brand replacement parts, and keep the receipt.
If the part you put on the car damages another part then it will void the warranty, but they, in this case Lexus has to through some kind of mechanical/electrical analysis prove without a doubt the new part damaged another part. That being said the onus is on the dealership to prove that the oil/air filter or even light bulb caused the issue.
Getting a tune or putting on a Turbo/Supercharger will obviously void the power train warranty as the car was not designed to handle all the extra power and stress that it will cause. Putting in a 100 watt bulb where a 5 watt bulb goes is another example as the higher wattage bulb can overheat the wiring, and cause a fire. Putting on 24" rims and then complaining about the ride quality is another example of what Lexus will say is not their fault. You see the pattern here? Doing things to your car that it was not designed to do will more than likely void some part of the warranty.
That is what the Better Business Office is for or better yet a good lawyer.
All I'm trying to do is educate you and others so that you are not intimated by the dealer to buy OEM parts where you do not necessarily need to.
Knowledge is Power. :nerd:
