At Diehl Auto Repair, we've built our reputation on honesty, integrity, and quality auto repair services you can trust.

When owner AJ DeBuono took over in 2016, Diehl Auto was a single shop. With a vision for growth and a passion for customer care, AJ expanded the business through hard work and dedication. Today, we’re proud to operate five full-service auto repair shops across Chicagoland, serving thousands of loyal customers every year.

Our team of ASE-certified mechanics provides complete automotive services, including brake repair, diagnostics, engine repair, tires, fleet maintenance, and preventative care. Every service is backed by warranty and performed with the same standard: treat every customer like family and every vehicle like our own.

From the very beginning, Diehl Auto Repair has been about more than fixing cars—it's about building trust, providing reliable service, and keeping our community safely on the road.
