I can call the dealership if nobody knows for sure but just checking if anyone has the answer from their own experience first.

I just bought a used 2020 IS300 f-sport and it was Lexus certified pre owned. I get the 2 year warranty in addition to the half year that is left on the 4 warranty from initial purchase. The car was L/certified by the lexus dealership.

I was thinking of doing some personal work on the car starting off with simple things like installing tansowerkz taillights, installing a different exhaust (need to research more into the specifics), and installing Apple car play. Does anyone know if modifying the car with simple things like taillight, exhaust, CarPlay voids the L/certified warranty?

 

If your work was around "anything" they can blame it on; prepare for a headache. Doesn't mean they are right but the will drag their feet on the uneducated. But if you ONLY do the exhaust and the head unit poofs; they cant logically claim connection.

So I would call and ask for the paper work. I got a thumb drive of what was covered/not covered when I bought mine. I have to imagine all the small print is in that drive as well.
