CV Auto on Main Street in Chula Vista runs a full-service mechanical shop from Suite K at 3290 Main, covering engine repair, electrical diagnostics, brake service, tire rotation, and collision-damage mechanical work for domestic and European vehicles including Mercedes-Benz, Volvo, and Jeep platforms. Engine-bay steam cleaning and undercarriage degreasing close out every major repair, a finishing step that keeps vehicles presentation-ready along the Main Street corridor shared with Soapy Joe's Car Wash. The diagnostic suite reads manufacturer-specific fault codes across OBD-II, CAN-bus, and proprietary ECU networks, enabling pinpoint isolation of sensor, solenoid, and module failures before disassembly. Tire-rotation and brake-inspection packages verify pad thickness, rotor runout, and wheel-torque specification at each service interval, complementing the dedicated tire-swap and alignment work at Hernandez Tire Pros on the same south Chula Vista corridor. The facility's highest-value repairs include head-gasket replacement on interference engines requiring cylinder-head resurfacing and crankshaft-to-camshaft timing verification within one degree of factory specification.
