I took my Honda in for new tires. It took three separate trips to the dealership, and nearly a week to complete this task after I made an appointment. It was a comedy of errors in which no two people in the service / parts / customer feedback departments could give me a consistent answer.
When the task was finally done, the invoice they printed me was not sufficient for a manufacturers rebate. I called, and called, and called. Always a promise that they'd make it right, but at this point, they have my money and I'm tired of trying.
