Why does an engine seize? incorrect oil level? incorrect oil? incorrect OCI for driving style?
Sure, some will fail due to MFG issues. But, there are times I will agree with the dealer. And, there are times that I would agree with the owner. The facts aren't known for all the complainers out there. Once the facts are gathered, usually by lawyer(maintenance records, owners competence, engine family history...), one could have a better understanding of the conclusion. Most automakers have escalation and steps to take if you disagree with the dealers 'voided warranty claim'. Most owners are too ignorant to prove their situation. Its easy to cry, complain, and pay.
All they have to do is increase the price, and include free lifetime service with the lifetime warranty. I wonder how the numbers are adding up at Cerebrus. What happened to the clown the milked and left homedepot? What company does he work for now? How many hundread of millions will he get to quit when he runs another company into the ground?
