2012 GMC Acadia Rolls Back while in Park
Hi all. I noticed that when I put my 2012 GMC Acadia in park, it rolls back about 3" or so, unless I set the parking brake. Given the transmission issues spoken extensively about in this forum, is this something I need to worry about ? I do have an extended warranty on the vehicle, so cost isn't really an issue.
I've always driven stickshift until now, so setting the parking brake is automatic, but I don't know if that is just masking the problem or not, if in fact it's a problem.
Any suggestions ?
