Local Service and Repair of HUMMER Vehicles

J-N-J Auto Service in Phoenix, AZ 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!

Give yourself and your Hummer the service you deserve—Call our shop or stop in to schedule an appointment today!

5-star review by Danniel Keyley

"I felt my trucks front end was needing some attention. And realized it needed immediate attention when I saw the right front tire was starting to wear a hole in the fender well. The turnaround was less than 24 hours, price very reasonable. I've been using J-N-J Auto Service for a while now. They are my shop of choice. My truck is riding as it should once again."

5-star review by Pamela Jenson

"I called at about 11am for an oil change. They said come right in. I did. And an hour later I was on my way home. They were very friendly and reasonably priced. I will go there again. It was clean and I could watch my truck being worked on in the bay on the TV in the waiting room. I will recommend this place to everyone."
