Chevrolet Repair & Service in San Marcos, Texas

About Chevrolet Service at Riley Auto Care

Chevrolet has been at the heart of American driving for over a century, and the vehicles they produce today — from the workhorse Silverado to the iconic Camaro — demand skilled, experienced service. At Riley Auto Care & Transmissions, we've built deep expertise in Chevrolet's full lineup and understand the specific maintenance needs that keep these vehicles performing reliably.

One of the most common issues we see in Chevrolet trucks and SUVs is Active Fuel Management (AFM) lifter failure on the 5.3L and 6.2L V8 engines. This is a known design concern that affects Silverados, Tahoes, Suburbans, and more. Our team can diagnose AFM-related misfires, perform lifter replacements, and even disable the AFM system to prevent future failures. We also specialize in the 6L80 and 8L90 automatic transmissions found across the Silverado and full-size SUV lineup.

As HP Tuners certified technicians, we can recalibrate your Chevy's ECU for improved performance, towing capability, or fuel efficiency. For Duramax diesel owners, we provide diesel-specific maintenance including EGR cleaning, fuel injector service, and DPF system care. Whether you drive a daily commuter or a heavy-duty work truck, we treat every Chevrolet with the attention it deserves.
