This week on Ron Ananian, The Car Doctor, Ron explains why the best repairs begin with the basics—not assumptions. A 2010 Ford Explorer with transmission trouble leads to a deeper discussion about water-damaged electronics, obsolete parts, and why replacing the obvious problem first often saves time and money. Then it's a conversation about Subaru's automatic stop/start system, warranty concerns, and whether aftermarket modifications really put you at risk.

Ron also welcomes Tony Ingram of Advance Auto Parts to discuss the right way to wash, wax, and protect your vehicle, including the growing popularity of ceramic coatings and why proper maintenance protects far more than just your paint. The hour wraps up with practical advice on restoring an older GM door latch when replacement parts no longer exist, plus a quick Mailbag answer on Nissan Titan steering repairs.

Whether you're chasing an electrical gremlin, wondering if a modification is worth the risk, or just trying to make your vehicle last another 100,000 miles, this episode reminds us that good diagnostics—and good maintenance—never go out of style.
