30 years of diesel expertise, now serving Southern Arizona fleets
We built Sonoran Fleet Care because we've seen firsthand what happens when businesses can't get reliable, expert diesel service.
The problem we're solving
Across Southern Arizona, thousands of businesses depend on diesel-powered fleets to deliver their services every single day. HVAC technicians, plumbers, electricians, roofers, solar installers, movers, construction crews, school districts — their vehicles aren’t just transportation. They’re the business itself.
Yet most of these companies face the same frustrating reality: finding a diesel shop that truly understands commercial fleet vehicles, communicates clearly, turns work around quickly, and keeps accurate records is surprisingly hard. Most general auto shops aren’t equipped for it. Most heavy truck shops cater to large carriers, not the smaller service fleets that keep our communities running.
The result is preventable breakdowns, missed DOT inspections, costly emergency repairs, and fleets sitting idle when they should be on the road generating revenue.
Unplanned downtime
Vehicles break down mid-job because maintenance was deferred or done incorrectly by shops unfamiliar with diesel systems.
Long wait times
Commercial fleets compete for appointment slots at shops that prioritize passenger cars, leaving fleet managers waiting days or weeks.
Poor record keeping
Scattered service histories make DOT compliance difficult and leave fleet managers flying blind on vehicle health and costs.
Surprise repair bills
Lack of proactive maintenance turns small, inexpensive issues into major repairs — at the worst possible time.
Built by someone who knows diesel from the ground up
Ben Natarajan
Ben Natarajan has spent three decades working in and around diesel engines — from on-road commercial trucks to off-highway heavy equipment in some of the most demanding environments imaginable. He’s seen the full lifecycle of diesel powertrains: how they’re spec’d, how they fail, and what separates a well-maintained fleet from an expensive one.
After years working in the heavy equipment industry, Ben recognized a clear gap in Southern Arizona: service companies with small to mid-sized diesel fleets had nowhere to turn for the kind of expert, attentive care that larger carriers take for granted. He founded Sonoran Fleet Care to fill that gap — bringing enterprise-level diesel knowledge directly to the businesses that need it most.
"Every fleet manager I’ve talked to has the same frustrations — waiting too long, getting vague answers, and finding out about problems after they become expensive. I started this business to change that experience entirely."
Keep Southern Arizona's fleets moving

“We don’t just fix trucks. We help businesses operate with confidence — knowing their fleet is in expert hands, their records are in order, and their vehicles will be ready when they need them.”
— Ben Natarajan, Founder
