Oil filter and oil change done at home. Purchased a bosch oil filter from autozone in ponchatuola, la. The dealer is saying the filter caused the engine damage, therefore it is not covered under the warranty. Autozone wants the filter back for inspection but has not involved bosch. If I let the filter go through the mail to autozone and they loose it I am without any evidence to justify any claim. I still feel my vehicle should be repaired by the dealer under warranty. I even purchased an extended warranty on this vehicle. The autozone insurance person I spoke with states the engine had to have too much pressure to cause the oil filter failure if it actually did fail. I'm left without a vehicle, a very large note, and too much stress to count.
