Common GMC and Buick Repairs

Some of the most common services requested at our service center are for simple fixes like oil changes, brake pads and rotors, or a wheel alignment. Getting your oil, brakes and wheels checked at least once each year is a recommended GM service. In fact, you should get a wheel alignment every time you change your tires over for the winter or put on a new set.

In addition to common repair services, it's no doubt that GM vehicles are getting more advanced in technology. Our team of trained mechanics can diagnose any sensor or engine light quickly and tell you what you need to get done within minutes. Our service department proudly uses OEM parts to ensure every service is done to GM standards, using GM parts, which will help you get the most of your resale value!

With incoming electric models like the Hummer EV or first-ever Sierra Denali EV, getting your vehicle serviced at a GM location can be advantageous. Not only can you use warranties purchased through GM on your new or used car at our dealership, but our mechanics are trained to handle any EV repair on your GM vehicle, including battery replacements and electrical or display system repairs. Ask us about you warranty information prior to scheduling so we can ensure you get the right deal!
