OUR WARRANTY

We stand behind every repair.

Written warranty on our labor, manufacturer warranties on the parts, and every job documented on your truck’s CARFAX history.

1 year / 12,000 mi

Labor warranty

Our labor on the repair is backed for 1 year or 12,000 miles, whichever comes first, under normal operating conditions. If our workmanship is the problem, we come back and make it right at no charge.

Manufacturer warranty

On the parts

New parts carry their manufacturer’s warranty (many batteries, tensioners and brake parts run 2 years or more). If a part fails under its warranty, the part is replaced under the manufacturer’s terms; labor to swap it is billed unless a separate labor agreement covers it.

Done right

Maintenance guarantee

The right fluids and filters for your engine, filled to spec, with no leaks. If something isn’t right, we come back and make it right.

CARFAX

Service reported

Every completed job is reported to CARFAX, so your truck’s service history stays documented for resale.

What the warranty doesn’t cover
  • Used parts, parts you supply yourself, or parts discounted below our standard pricing
  • Trucks without documented maintenance at the manufacturer’s intervals (keep your receipts)
  • Normal wear items, like brake pads and wiper blades, once they wear out
  • Failures from lack of maintenance, fluid contamination, overheating, lubrication starvation, overloading, accidents or severe/commercial abuse
  • Parts installed on performance-modified or tuned trucks
  • Problems we recommended fixing that weren’t approved

Warranty work must be done by us. Call 520-990-1033 and we’ll come to you. Full terms are on your invoice.

OWNER QUESTIONS

Before you book.

Do you really do repairs at my house or job site?

Yes. We’re a mobile shop and come to homes, job sites, yards and roadside locations around Tucson. We confirm space and access before we schedule.

What if the repair can’t be done on site?

We tell you up front. Most repairs can be done where your truck is parked; for the few that can’t, we explain your options before any work.

Do you work on gas trucks too?

Yes. We service Ford, Ram, Chevrolet and GMC gas trucks as well as diesels.

Will you clear my check engine light?

We find and fix what set it. Clearing an emissions code without a repair usually brings it right back, often with a derate.

READY WHEN YOU ARE

Let’s get your truck back to work.

Tell us what you’re driving and what it’s doing. Decode your VIN and we’ll match the right service and rate class.
