These people over charge for mediocre work done. On two occasions I have had my oil changed and each time something was done wrong...One time they put the wrong type of oil in, but each time I had it changed my vehicle leaked afterward. Recently I renewed my GMPP extended warranty, but when it came in the mail it was from a totally different warranty company, that did not offer half of what GMPP did. From my experience they are sneaky and will try to get over on you every opportunity they get. If you catch them they will attempt to fix it...but who wants to have to watch everything that is done to their vehicle. It's like having the work done at Greiner, then taking it to someone else to make sure they did the right thing in the first place. JUST CUT OUT THE MIDDLE MAN "GRIENER" GMC DEALERSHIP in VICTORVILLE, CA. ENTER AT YOUR OWN RISK!!!
