DeMontrond Buick GMC - Service Center

Worst service experience of my life (I am 49). First of all, the Advisors don't return calls. I had a lot of work done on my Grand Prix. I had a new supercharger installed (the belt was not installed prope all, the Advisors don't return calls. I had a lot of work done on my Grand Prix. I had a new supercharger installed (the belt was not installed properly, causing wobble & squealing). Additionally, the technician left my radiator overflow hose loose & laying on the belt, causing it to be shredded. I left multiple messages with my Advisor, no return calls. Eventually, I took the vehicle back in & my original Advisor was out, so a different Advisor helped me. He had the technician fix the belt & said he would order a new hose & call me back to schedule an appointment. He even filled out paperwork, but.......you guessed it, no return call. I also had new speakers installed due to electrical short (I was told that the technician ran new wiring all the way back to the stereo. When the shorting persisted, I pulled one of the speakers to find that no new wiring had been done). The poor service is one thing, but being out-and-out lied to is another. Do not take your vehicle to this dealer!!!! More
