We tell you what's wrong before we touch the car
Our story
JNT Automotive Repair is a family-run shop in downtown Merced. John runs the bays, his wife runs the front counter, and between them you get something that has become rare: a mechanic who picks up the phone, tells you exactly what is wrong with your car, and explains what it will take to fix it before any work begins.
We handle the everyday work — oil changes, brakes, tune-ups — and the stubborn problems other shops send away. Customers regularly bring us intermittent AC faults and steering jobs that were turned down elsewhere. When a repair needs parts, we order them the same day wherever we can, so your car is back on the road instead of sitting in a lot.
Some of our customers came back after years away and found the same two people behind the counter. That is the shop we want to be: one you only have to find once.
What customers say
“JNT is an amazing car repair. The service is one of the best in Merced. They are courteous and very helpful. They will explain everything about the repairs in detail and the appropriate action to take. John is honest and very helpful. You can't go wrong.”
“John is a genuinely kind and decent man — he talked us through all of the issues we had with our two Subarus. We wanted to get our vehicles checked before a long roadtrip (2500 miles or so!). I needed brakes, an oil change, and have had a persistent issue with my AC that other shops couldn't figure out — John & team did solve it in no time! Parts ordered and delivered same day!!”
“JNT fixed my AC issue in my truck in just a few hours. The receptionist was very friendly and professional over the phone as well as in person. The price was more than reasonable which is hard to find these days.”
