The South Valley is a large, mostly unincorporated stretch of Bernalillo County along the river — agricultural in places, residential in others, and full of working trucks and long-owned family vehicles. Auto Masters is a straightforward drive north on 2nd St or 4th St, and because we are an independent shop rather than a chain, the estimate you get is based on what the vehicle actually needs.
Getting to Auto Masters from the South Valley
The simplest route is 2nd St or 4th St north through the Barelas and downtown area and up into the North Valley — we are at 4201 4th St NW near Griegos. Isleta Blvd to 2nd St also works from the west side of the valley. Figure 15 to 25 minutes depending on where you start and traffic through downtown.
What We Work On
Full-service repair and maintenance: brake repair, transmission service, engine diagnostics, oil changes and scheduled maintenance, AC and heating repair, failed-emissions help, and exhaust and catalytic converter work. If you drive an older truck or a high-mileage family car, our approach is to keep it safe and reliable at a fair price rather than pushing you toward a new-car payment.
South Valley Drivers We See
Owners of work trucks and trailers who need brakes, cooling, and driveline kept in shape. Families running a vehicle well past 150,000 miles who want honest advice on what is worth fixing. Drivers who failed a Bernalillo County emissions test and need the cause found and repaired, not just the code cleared.
Frequently Asked Questions
Do you help with failed Bernalillo County emissions tests? Yes. The South Valley is in Bernalillo County, so most gas vehicles need to pass. We diagnose why the vehicle failed — check engine light, converter, EVAP, oxygen sensor, or unset readiness monitors — repair it, and confirm the monitors are set before you retest. See our emissions repair page.
Is your pricing fair for older or high-mileage vehicles? That is most of what we do. We tell you what needs attention now for safety, what prevents an expensive failure later, and what can wait — so you can spend the repair budget where it counts.
How long does the drive take from the South Valley? Usually 15 to 25 minutes — 2nd St or 4th St north through downtown to 4201 4th St NW. Dropping the car for the day avoids the round trip twice.
