For the first time since we started taking our cars here (2012), we have some concerns. We took both our cars in on Saturday and both had after-service problems. The check engine light went on in my wife's car 5 miles from Greulich's, so we took it right back to find that one of the hoses under the hood wasn't fastened securely. The pan under my car wasn't fastened securely, either...and started dragging the street...so that car had to go back so that the pan could be properly fastened. Having to return both cars for sloppy work or poor workmanship is a concern made doubly concerning when I called to talk to Stan and was told he had left Greulich's. We know Stan did not actually, physically do any work on our cars but we knew he inspected ALL work and that gave us confidence in him and the shop. Given Stan's departure and our recent experience, we're not sure we'll continue patronizing this business.
