I have a 2007 Chevrolet Suburban and about a year a half ago I had to replace the engine, mileage was about 176K miles. My wife noticed the engine running a little rough recently and took the vehicle in to the GM dealer where the engine work was done. They informed her she needed new motor mounts at a cost of $1800.00. From all the research I've done, it seems ridiculous that the dealer did not mention changing these out when the engine was replaced, and when I inquired, I was informed by the Maintenance/Service Manager, we would have looked at that and if they needed to be replaced we would have informed you. I don't see how a vehicle with 176K miles would not need new motor mounts or why at least with a vehicle with that many miles, the GM dealer would not have recommended we go ahead and change those out while the engine was being replaced. I would like to get some insight on general industry practices for this scenario as I think we were and are being taken advantage of by GM.
