Come see why Drivers from Ontario, Riverside, Corona, San Bernardino and Fontana Say STG Auto Group Works Wonders Under the Hood

Whether your car is in need of an oil change or you hear a strange sound when braking, STG Auto Group is standing by to assist you in any way possible. Our auto service and repair department knows Audi, Ford, BMW, Chevrolet and Dodge models inside and out, so they know how to keep your Audi A4, Ford Mustang, BMW 328i, Chevrolet Silverado 1500 or Dodge Charger running efficiently - and how to get it back on the road when a larger fix is needed. That means minimal down time on your end, as well as better potential resale value for your car.

Among the many ways that our skilled technicians keep your car in excellent shape is a commitment to using only certified Audi, Ford, BMW, Chevrolet and Dodge parts. That means you can count on your vehicle looking and functioning as though it had just rolled off the assembly line.
