So I own a 2014 Corolla S and I'm thinking about doing a lot to it, things from under the hood to how it looks inside and out. But I want to know if anyone here knows what will void my warrant and what won't
If they can trace back any mod you do to a thing that goes wrong(and you bet they will) it will void the warranty on the affected parts. An exhaust may not void your suspension warranty but could affect engine things for example.
