It is your job to track mileage and to know when it is time to get the oil changed. The dealer has no way of telling how many miles you have driven. If you told them to change the oil and they did not it is still your problem as you should have checked the paper work to see what they charged you for. Unfortunately in that case it is your word against theirs. Part of owning a car is being aware of the maintenance needs which are spelled out in your owners manual.


When you order service they will fill out a form which you sign indicating the services to be performed. If you have that paper work and it says to change oil and they did not then you have a case.


A knocking engine is probably a rod knock resulting from running the car out of oil. You will almost certainly need a new engine - Sorry.

Yes they are saying it is probably a rod they're wanting to tear the motor down and find out if it is covered under warranty it is a drivetrain no matter how you look at it I don't know what they can find out by tearing it down because I did not make the motor so that is one of the drivetrain is covered under warranty and I will be liable for rebuilding the motor if they find an unjust Cause whatever that means even if it comes down to the oil not being changed on time I have receipt from certified mechanic saying he changed my oil and put exact grade oil and filter that maintenance manual requires I am just wondering what will they look for when they care of the motor down


They will look for damage to the bearings and other moving parts of the engine. If you have receipts proving you changed oil regularly then you should be covered. Be sure and hold onto those receipts. I would give them copies. If you went 16,000 miles between changes you are probably out of luck but good luck anyway!
