Our story
Fontana's Straight-Talking Neighborhood Mechanic
Mailo's Auto Repair has built its name in Fontana one honest diagnosis at a time. Customers come to us with everything from a dying battery to a car that needs a whole new engine, and we tell them exactly what's wrong and what it'll take to fix it: no mickey mouse jobs, no upsells.
We handle the full range of repair work ourselves: fluid and spark plug service, throttle body and fuel injector cleaning, cooling system repairs, alternator and battery replacement, and complete engine swaps. Many jobs are finished the same day, so you're not stuck without a car any longer than you have to be.
We're part of this neighborhood, not just a shop in it. Customers have found us through word of mouth from local businesses down the street, and they keep coming back because we do what we say we're going to do.
- Same-day turnaround on most repairs
- Full engine swaps to routine maintenance
- Straightforward, honest pricing
- A trusted name in the Fontana community
What customers say
“I had a great experience here. I brought my car in to change all the fluids and check the engine and transmission mounts because the car started to shake. They changed all my fluids and spark plugs, cleaned the throttle body and fuel injectors, and even cleaned the engine bay. Recently I had a 'engine maintenance required' indicator — they replaced the coolant bypass valve for a fair price on labor. They always have my car finished the same day. Great service.”
“I brought my car in because it kept dying and Milo was so helpful and honest — he told me I needed a new alternator and battery, he repaired it in one day and hadn't had problems since. Highly recommend especially for women.”
“My car needed a whole new engine. It got swapped out in a week and any questions I have regarding the car he answers them. It was affordable and very professional work. No mickey mouse job. He is also a very honest mechanic. I will be back.”
