Our story
Muñoz Auto Repair has been keeping Ontario vehicles on the road with honest, straightforward service. We handle everything from routine tune ups and oil changes to more involved work like timing belts, water pumps, alternators, and differential service, so you can bring us nearly any mechanical issue and leave with a clear explanation of what it needed.
Customers keep coming back, and keep sending their family and friends, because we tell them exactly what's wrong and what it costs before we start. No hidden costs, no upsells you didn't ask for, just the repair your vehicle actually needs.
We treat every car like it's our own, and every customer like family. That's why so many of the people who walk through our door already know someone who trusts us with theirs.
