Established in 1991 as a NAPA Auto Care center, C & D Auto Care at 7167 University Avenue in La Mesa provides ASE-certified mechanical service on domestic, European, and Asian platforms. The shop handles brake, suspension, and alignment work alongside engine diagnostics and drivetrain repair, referring tire-specific replacements and balancing to specialists like Evans Tire when tread depth or sidewall damage warrants a dedicated tire facility. The NAPA Auto Care affiliation backs qualifying repairs with a nationwide 36-month/36,000-mile parts-and-labor warranty honored at any NAPA Auto Care location in the country. Diesel service and repair expands the shop's reach beyond gasoline platforms to cover Duramax, Cummins, and Power Stroke drivetrains common in La Mesa's commercial and towing fleets. Emergency breakdowns along University Avenue and the Fletcher Hills corridor arrive by flatbed through towing services like Tow For Less, feeding the shop's diagnostic queue without requiring the driver to schedule ahead. Complex engine diagnostics employ OBD-II live-data streaming and oscilloscope-verified sensor waveforms to isolate misfires, lean-condition faults, and EVAP integrity failures before authorizing component replacement.
