HUMMER Service and Repair 

If you enjoy driving a HUMMER, but need someone in the Prescott area for expert auto repairs, the auto mechanics at Certified Transmissions Complete Auto Care would like a word with you. You see, we understand what you love about your HUMMER. HUMMERs are tough, capable vehicles and they can handle the terrain around Prescott quite easily. 

As tough as HUMMERs are, they still need regular maintenance. That’s where our auto repair specialists at Certified Transmissions Complete Auto Care come in. We’ve been repairing HUMMERs for years. Even though they’re no longer being manufactured, people around Prescott still love their HUMMERs. We don’t see as many as we used to, but they’re still out there. 

Why bring your HUMMER into Certified Transmissions Complete Auto Care? Maybe our four decades of experience will convince you to come in. Or maybe it’s the integrity and honesty that we’re known for. Or our 2-year/24,000 warranty and our own extended 4-year warranty! 

Does Certified Transmissions Complete Auto Care offer thorough service? Here’s a five-star review from a happy client in Prescott:

“Quick in & out for service. Thorough on checking what ails my auto. Sometimes more than I can do at once financially, so they tell me what is the worst and what can wait a bit. This time I had a transmission leak, a power steering leak, an oil pan leak, and need new brake pads. Two down and two to go. I am a 65 year old woman and feel perfectly comfortable in their shop. Nice guys!” -- L. Lewis
