Right diagnosis the first time. Estimates that hold.
Our story
R&R Automotive is an independent repair shop on Oakdale Road in Modesto, run by Rob. Customers come here after being told one thing somewhere else and finding out it wasn't true: a check engine monitor that won't reset, a diagnosis that never quite fit, an estimate that kept growing. Rob does the diagnostic work himself, tells you what he found, and fixes what actually needs fixing.
That approach shows up in the reviews. One customer's brake estimate came down after Rob assessed the car and found the rear pads didn't need replacing. Another's fuel pump job came in under the original estimate, with a collapsing fuel line replaced and the rest of the car looked over at no extra charge. People bring back the same cars for years, and Rob remembers them.
The shop is easy to miss: the entrance is on Oakdale Road between the smoke shop and CT Transmissions. Drive back to the buildings in the rear.
What customers say
“My 2020 Honda Civic broke down and Rob was able to diagnose it and replace the fuel pump within a week with no notice. He also replaced a fuel line that had begun to collapse and checked over the rest of the car for no extra charge and even was under his original estimate total. He is a man of integrity and is very good at what he does.”
“It was refreshing to deal with a true small business owner who is honest and believes his integrity is important in his life. When was the last time you dealt with a shop that revised an original estimate down because when assessing my brakes found I didn't need the rear brake pads replaced? Here is an auto repair service where you can get quality work and feel confident you are being treated fairly.”
“I was getting a lot of misinformation about why my CAT monitor wasn't resetting so the car would pass smog. Within a matter of minutes Rob was able to identify the problem and had the repairs done, took the car to his smog guys and had my car back to me the next day.”
