Wiesner Buick GMC - Service Center

Took my 2006 GMC Envoy to dealer for low oil pressure, told them there must be leak even though no obvious source because I had added 5 quarts in last 2 months. Tech said "no, the code only indicated oil told them there must be leak even though no obvious source because I had added 5 quarts in last 2 months. Tech said "no, the code only indicated oil pressure sensor failure, you must have just not added enough." Kept it all day and charged $500+ to change out sensor & add oil. Of course, the problem persistend. Took it to the neighborhood mechanic who used his eyes, ears, & knowledge to figure out in 5 minutes that both valve cover gaskets were blown & leaking, said it's a common problem on GM 5.3L V8. He replaced them (and sensor, again)--no problems at all in the 7 months since. Then more recently, took it to Wiesner for an air conditioning vent problem. Again kept it all day, when they called me to pick it up it wasn't fixed, Sabrina said sorry, tech on duty that day wasn't familiar with the CODE for an air handler problem. Why ever buy from a dealer with a totally incompetent service department? More

I would recommend this Dearlership for both sales and service. Bill Marquis is exceptional to work with. The service Department is very clean and efficient. The guest waiting room is comfortable and v service. Bill Marquis is exceptional to work with. The service Department is very clean and efficient.
