Purchaced a new '08 in September. Took it to the dealer last week to repair a break squeak. They told me that they had to replace a bolt. Okay for a few days and then I developed a LOUD rubbing/grinding noise whenever I apply my breaks. Took it back in and they've had it for two days now and don't know what the problem is.
I'm concerned because I'm getting little input from my rep. He says it is a lubrication issue and that no damage is being done to the pads or rotors. Supposedly they are working with GM to try and resolve as the lubricants they've tried so far have not resolved the issue.
Any thoughts as to what the problem could be? I'm quite concerned as I'm leaving on a one month road trip the day after Thanksgiving.
