Ron Ananian, The Car Doctor - January 10, 2026 - Hour 2 - One Chance to Do It Right: Dealer Disputes, Exhaust Surprises, and Battery Timing
About this episode
Ron Ananian tackles a range of automotive issues in this episode, focusing on dealer disputes, exhaust system repairs, and battery maintenance. A caller shares a frustrating experience with a missing wheel well cover after a headlight assembly replacement, prompting a discussion on dealership accountability. Ron also recounts an unusual day in the shop with three exhaust system repairs, highlighting the intricacies of diagnosing and fixing exhaust leaks. Additionally, he emphasizes the importance of timely battery replacements, especially for low-mileage vehicles, and shares insights on the longevity of Mazda vehicles.
This hour, Ron tackles a dealership dispute after a headlight replacement—when a customer later discovers the entire inner wheelwell liner missing and can’t prove who removed it. Ron explains how to use factory procedures and documentation to hold a shop accountable and why missing liners can become a real corrosion and safety issue.
Plus: a rare day in the shop—three exhaust repairs in one day—including a Toyota Highlander with a subtle flange leak that snowballed into hardware repairs and an O2 sensor surprise. Then Ron weighs in on oil viscosity “advice” from YouTube, a Mazda CX-5 deal for a high-mile commute, and when to replace a battery on a low-use vehicle—especially with today’s electronics and battery monitoring resets.
