HUMMER Repair & Service
at Jefferson Auto Service
HUMMER drivers don’t settle—and neither do we. At Jefferson Auto Service, we provide expert HUMMER repair and maintenance in Harrison Township, Clinton Township, and Romeo. Whether you’re behind the wheel of an H2, H3, or one of the newer electric HUMMER EVs, our ASE-certified auto mechanics have the tools and experience to keep your rig performing like it should.
Big, Bold, and Built to Be Worked On
HUMMERs are known for their off-road capability, rugged styling, and heavy-duty components. But with that extra size and strength comes the need for specialized care—and our team is ready for it. HUMMERs share engineering DNA with GM trucks, which we service daily, giving us deep familiarity with their systems.
We offer HUMMER services including:
- Oil changes and maintenance plans
- Brake inspections, pads, and rotors
- Suspension work and steering repairs
- Battery, alternator, and starter diagnostics
- Cooling system repair and radiator service
- Engine performance diagnostics and repairs
- Tire rotations, alignments, and steering system checks
- EV support (limited; based on model and system access)
Not sure if your HUMMER repair is something we can handle? Just give us a call—we’ll take a look and give it to you straight.

Why HUMMER Owners Come to Jefferson Auto Service
We’re not intimidated by size, weight, or complexity. At Jefferson Auto Service, we bring the same level of care and precision to your HUMMER that we bring to every vehicle we work on. And because we take time to diagnose before we recommend, you get service that’s clear, honest, and never rushed. Even when no work was done, the service still stood out:
"Even though they didn’t end up doing work on my vehicle this time, they were extremely thorough and helpful. I really liked getting my quotes via text—it made everything easier."
– Adrian M.
