Reliable Auto Repair Shop in Whitmore Lake, MI

At Ronin Auto, we prioritize honest diagnostics, transparent pricing with written estimates, and quality workmanship backed by strong warranties. We focus on building long-term relationships with clear communication, no upsells, and customer-first service.

Ronin Auto offers high quality, full synthetic oil, which we recommend changing every 5,000 miles.

The check engine light (CEL) signals the vehicle's computer has detected an issue. This is often emissions-related, but sometimes indicates a more serious problem. A solid light is not necessarily urgent, while a flashing check engine light means stop driving soon (possible misfire damaging the engine).

Brakes typically last 30,000-70,000 miles. Squealing may indicate the pad life is running out, while grinding or scraping may be more urgent, as this can indicate rotor damage.

Preventive maintenance is regular scheduled services like oil changes, tire rotations, brake checks, and fluid/filter replacements. It extends your car's life, improves efficiency and performance, boosts safety, prevents breakdowns, and saves money by catching small issues early instead of expensive repairs later.

Yes, we provide free, no-obligation written estimates for most diagnostic and repair services. We'll explain the issue, recommended fixes, parts, labor, and the total cost estimate. You approve everything before the work begins.

We stand behind our work with a standard 12-month/12,000-mile warranty on most parts and labor, unless otherwise noted. (Some items, like major components or premium brands, may qualify for longer coverage, such as lifetime on certain brakes or exhaust).

We accept payment from major credit/debit cards (Visa, Mastercard, Discover, American Express), cash, checks, and financing options through Affirm. We also work directly with aftermarket warranties, extended warranties, and insurance companies for direct payment where applicable.
