My neighbor Lets call him Joe, has a 90,000 GMC Denali pick up. He loves it but told me an interesting story.
Within a short time after Joe took delivery of the vehicle, it developed a lifter tap and after futile attempts to quite he thing the dealer finally decided that it needed the lifters replaced at some 11,000 miles. His Response was "I just spent 90,000 Dollars on this truck I want a new engine". The Shop called and said it was done. He quickly asked if they replaced the engine. To his disappointment they did not. GMC Only approved the new lifters. When Joe went to the Dealer and spoke with the service manager, he reiterated his original objection. When they refuse Joe stated he would be back to hold a picket sign out front tomorrow. They thought he was joking. However he wasn't. After seeing him hanging out in front of the dealership a few hours and talking with numerous people about his experience, while watching person after person turn around and leave they decided he was serous. At some point a tall man in a fancy suit came walking out and met him on the sidewalk. He asked Joe how he could make it right, he offered and extended warrantee, cash settlement. My neighbor said you know what I want. The man asked Joe to please come back into the service department and they will get him a ETA on a new engine. Within a month Joe had the new engine installed. My point, sometimes we have to be taken seriously. Spend days in court or spend a few dollars and picket your point. a few hours can sour the ideals of people. Especially if you mention the local paper or tv news channel. If it doesn't work out you have a choice. Just a few sales would be the cost of a new engine. It would cost the dealer nothing to cover a warrantee for 50,000 miles say. or $6.000 for an engine job. It would cost twice that in court. If they are so certain no harm was done (which we ALL know there was some) an extended warrantee is their best option. IMO
