GMC Service and Repair in Walnut Creek, CA

If you own a GMC vehicle that needs service or repairs bring it to Diablo Auto Specialists so it can receive the care it needs – we are the GMC service and repair shop in Walnut Creek. Whether your GMC Acadia needs new brakes, or your Sierra 1500 diesel needs new glow plugs our technicians will get the job done right, the first time.

Like all vehicles, GMC trucks and SUVs require regular maintenance. Our Walnut Creek auto repair shop offers full range of automotive maintenance services as well as a wide range of auto repairs. We are big fans of basic preventive maintenance – the oil change. We recommend following the schedule of maintenance services as laid out by the manufacturer, and regular oil changes every 5000 miles or so. Oil change done regularly prolongs engine life, and tire life as well, since we suggest tire rotation while doing the oil change. We also perform a free digital vehicle inspection, so you are always up-to-date on the current condition of your GMC.

Following GMC recommended maintenance schedule keeps the original warranty in force.

If during the digital inspection we find items of concern, we will show you (you get electronic copy of the results, with pictures) what we found, and provide you with information on what can be done, and how to prioritize the work, if multiple items are found.

Diablo Auto Specialists is a family owned auto repair garage in Walnut Creek that combines superior customer service with technical excellence, and genuine concern for our clients. During a visit to our auto care facility, you will find clean office, friendly service advisors, professional technicians using state-of-the-art digital diagnostic tools, together with:

  • 36 month / 36,000 miles nationwide warranty
  • Original Equipment equivalent or better quality parts
  • Electronic copy of our complimentary digital vehicle inspection
  • Local Uber/Lyft for your convenience
  • Nationally ASE certified mechanics working on your GMC
  • Priority fleet service

Naturally we also work on hybrid vehicles, so if your GMC should happen to be of the hybrid variety, we can repair and service it as well. Here are some of the GMC vehicles we support:

GMC Sierra 1500 and Sierra 2500 are reliable, and serve not only for weekend projects, but also as vehicles for many trades. Especially for pickup trucks used for work, we recommend regular oil changes, tire rotations and brake inspections. If you own a fleet of GMC pickup trucks, Diablo Auto Specialists offers priority fleet service.

GMC Yukon 2007 model had problems with excessive oil consumption, but since then J.D. Power and Associates named it the Most Dependable Large SUV for 2015 and 2016.

GMC Acadia 2007 and 2008 had transmission and engine problems. 2010 model could suffer from premature timing chain wear.

GMC Canyon 2015, 2016 and 2018 can suffer from transmission problems.

GMC Savana Cargo / Passenger vans have been around for over two decades. They seem to be pretty problem free vehicles. We offer priority fleet service, whether you own a couple of these vans, or a couple dozen.

GMC Terrain named 2015 Most Dependable Compact SUV by J.D. Power is a true turnaround story, because early Terrain models suffered from transmission problems.
