Trusted Mechanic in Rocklin, CA
Nex Automotive is a full-service mechanic shop in Rocklin, CA specializing in modern vehicles — including advanced ADAS systems, electric and hybrid powertrains, and the complex wire harnesses that connect them. We’re not a quick-lube chain. We’re a diagnostic-first shop staffed by technicians trained on the systems that make modern vehicles work.
Whether you’re chasing a check engine light, need scheduled maintenance, or have a mechanical issue that another shop couldn’t diagnose, we have the equipment and experience to handle it.
What Makes Us Different From a Standard Mechanic
Most traditional mechanic shops are equipped for the vehicles of 20 years ago. Modern vehicles — especially those built after 2018 — are fundamentally different. They have multiple ECUs talking over a CAN bus, cameras and radar calibrated to millimeter tolerances, and brake/suspension systems that interface directly with electronic safety features. Fixing the mechanical problem without understanding the electronics often creates new problems.
At Nex Automotive, mechanical repair and ADAS calibration are handled by the same team. When we fix your suspension, we check whether the fix requires recalibrating your radar or camera. When we replace a windshield, we recalibrate the forward camera. When we do brake work, we verify AEB performance. This is how modern vehicle repair is supposed to work.

Check Engine Light Diagnosis
A check engine light can mean dozens of different things. We use factory-level scan tools — not just generic OBD readers — to pull manufacturer-specific codes and live data. We’ll tell you exactly what’s wrong, what it affects, and what it will cost to fix before we touch anything. No surprise bills.
Wire Harness and Electrical Repair
Wire harness damage is one of the most underserved areas in automotive repair. Rodent damage, corrosion, and crash damage can affect dozens of circuits at once. Nex Automotive has wire harness repair specialists on staff — we can diagnose and repair individual circuits without replacing entire harnesses, saving you thousands of dollars on vehicles where the harness alone costs $1,500–$3,000.
