Service and Repair of HUMMER Vehicles

Mayo Autoworks 2 and Mayo Autoworks 3 in Killeen and Harker Heights, TX has a team of specialists dedicated to Hummer vehicles. Marketed by GM from 1999 through 2010, Hummer vehicles are no longer being made, but they remain versatile recreational vehicles that combine size, status, and immediate recognition into one huge package. Whoever said that good things come in small packages never took the Hummer into consideration. The civilian version of the military Humvee, Hummers can be used on or off road in nearly any environment. Each Hummer is as unique as its owner. A vehicle this individualized needs specialized care and maintenance.

Off-roading can cause a lot of wear and tear on a vehicle—even if that’s what a vehicle like the HUMMER is designed for. Excellent service and routine maintenance will keep your HUMMER reliable through all terrain. At our shop, we offer individualized high-quality service to keep your Hummer in optimum condition. Whether you drive an H1, H2, or H3, we are qualified to meet all of your automobile’s needs. From major repairs to routine services, our expert technicians stand ready to offer nothing less than the best in customer and car care.

Unlike other shops, we don’t just focus on the vehicle. From the moment you enter our door until you drive away completely satisfied, we strive to offer an excellent customer service experience.

Our certified technicians are always happy to answer any of your questions, and we work hard to get you back on the road (or off-roading) as quickly as possible!
