Trailers take tremendous abuse — heavy loads, rough roads, weather exposure, and long periods of inactivity. Yet they're often the most neglected part of a towing setup. At Hahn Automotive in Santa Rosa, we service all types of trailers: utility trailers, horse trailers, boat trailers, cargo trailers, and work trailers.
We specialize in trailer brake systems (electric brakes and surge brakes), wiring and lighting repairs, coupler and hitch work, axle and bearing service, and structural repairs. If your trailer's brake controller is throwing codes, your running lights are intermittent, or you're hearing grinding from a wheel bearing, we can fix it.
Proper trailer maintenance isn't just about convenience — trailer brake and lighting failures are safety hazards for you and everyone on the road around you.
