Car trouble? Start with a clear diagnosis.

A warning light or a car that won’t start can interrupt your whole day. R&I Mobile Mechanic provides mobile diagnostic appointments at homes and workplaces in Garden Grove and Orange County, helping you understand the problem and the next step.

Local diagnostics from $80. Diagnostic fee waived when R&I completes the diagnosed repair.

Check-engine light and driveability concerns.

Tell us about warning lights, rough running, hesitation, or a change in how the vehicle drives. Depending on the concern and vehicle, diagnosis may include a scan, visual checks, and targeted testing. A trouble code is a starting point for investigation; it is not automatic proof that a specific part needs replacement.

No-start, battery, and charging concerns.

If the vehicle clicks, cranks slowly, or will not start, describe what happens and any recent battery or repair work. We assess the relevant starting and charging components and explain whether further testing or a repair is needed.

Know the cost before the visit.

Local diagnostics start at $80. The diagnostic fee is waived when the diagnosed repair is completed by R&I. Vehicle requirements, location, and the testing needed can affect pricing. We confirm the scope, price, and any travel charge before booking; repairs receive a separate estimate.

A practical plan after testing.

We explain the findings and recommended next step. Some intermittent faults require more time or follow-up testing, and some work may require a shop. We confirm whether the repair is suitable for mobile service rather than promise every problem can be fixed in one visit.

Common questions

Is a code scan the same as a diagnosis?

No. A code scan can point to a system or condition. Diagnosis uses the symptoms and appropriate checks to investigate the cause before a repair recommendation.

When is the diagnostic fee waived?

The diagnostic fee is waived when R&I completes the repair identified through that diagnosis. If you do not proceed with that repair, the diagnostic charge applies. We confirm pricing before booking.
