Ron answers a wide range of listener questions that all come back to one idea: smart maintenance pays off. From choosing the right spark plugs for a classic '69 Chevy Nova to synthetic oil change intervals, reviving a stored Honda CR-V, and whether to disable auto stop/start on a late-model Acura, the focus is on making vehicles last longer.

Plus, Ron explains why diesel fuel additives can be a worthwhile investment for owners of today's modern diesel trucks.

The Perfect Storm of Auto Repair

A simple A/C complaint on a 2015 Jeep Grand Cherokee quickly turns into a lesson on why repair estimates are only educated guesses. Ron explains how one failed component can uncover several more—and why proper diagnostics always come before replacing parts.

Also this week, Ron helps a listener solve a persistent EVAP system fault on a Kia Soul, explains why testing beats guessing every time, and answers questions about suspension noises and airbag warning lights.

Real diagnostics. Real repairs. Car Advice, Done Right.

Don't Let the Little Things Ruin Your Trip

Before you head out for your next road trip, Ron Ananian, The Car Doctor, has one simple question: Do you know where your wheel lock key is? It sounds like a small detail—until a flat tire leaves you stranded hundreds of miles from home. Ron shares a real-world story that proves the little things can quickly become big problems when you're on the road.

Also this week, Ron helps a listener choose between Ford's 2.7L EcoBoost and the legendary 5.0L V8, works through no-start problems on both a classic Mazda pickup and a Nissan Titan, catches up with Wall Stadium racer Quinn Trimmer for a mid-season racing update, and answers a listener's question about costly oil leaks on an aging Subaru.

Whether you're traveling across town or across the country, a little preparation—and a little automotive knowledge—can save you time, money, and a whole lot of aggravation.

Automotive Couples Counseling

Can a husband and wife experience the exact same car problem and remember it completely differently? This week on The Car Doctor, Ron Ananian explains why the most valuable diagnostic tool in his shop isn't a scan tool, lab scope, or smoke machine—it's the chair in front of the service counter. After listening to a couple describe an intermittent stalling problem from two very different perspectives, Ron discovers that the missing clue wasn't under the hood at all. It was hidden in their story.

Also this week, Ron helps a listener decide whether to restore a beloved 7.3L Ford Power Stroke with over 300,000 miles or move on to a newer truck, tackles a mysterious engine failure after questionable fuel finds its way into a late-model Silverado, explains an unusual Toyota Camry touchscreen problem, and answers a mailbag question about a Honda Accord that began overheating after collision repairs.

Sometimes the best repair starts with a conversation.

A late-model Ford Edge had everyone stumped. Multiple repair shops, multiple replacement parts, no check engine light, and no diagnostic trouble codes—yet it still refused to start.

Ron explains why the best diagnostics begin before the engine is ever cranked, using live scan tool data like coolant temperature, ambient air temperature, battery voltage, fuel pressure, and barometric pressure to verify what the PCM believes is happening. It's a lesson in real-world troubleshooting that every technician—and every vehicle owner—can appreciate.

Also this hour:

• A discussion on complete automatic transmission fluid exchange procedures.
• A Hyundai Palisade with excessive oil consumption and what owners should expect from the manufacturer.
• A Kia Sportage with stubborn brake bleeding issues after multiple hydraulic repairs.
• Why diagnostics should always begin by identifying what's working correctly before chasing what's broken.

As Ron reminds listeners:

"Tell me what's good... and I'll tell you what's bad."

This week Ron explains why great technicians don't start by replacing parts—they start by proving what's actually wrong.

A stubborn Honda Accord air conditioning problem, a Ford Edge with two unrelated faults, and a discussion of real-world diagnostic strategy all reinforce one lesson: understanding how a system works will always beat guessing.

Also this hour:

• Why testing beats replacing.
• Ford Edge A/C diagnosis after collision repairs.
• Battery failures that don't behave like battery failures.
• Maintenance advice for a high-mileage Ford F-150.
• Chrysler cruise control problems.
• Why today's technicians must understand how modern vehicle systems communicate.

As Ron says:

"The challenge isn't how many parts you can replace. It's how many parts you can NOT replace and still fix the vehicle."

This week, Ron dives into the ever-growing role of technology in automotive repair. First, he welcomes Hugh Atkins of Drew Technologies for a discussion on computer flashing, module programming, and why software updates have become a routine part of modern vehicle service.

Ron then takes a call on a 2010 GMC Savana 3500 and discusses the pros and cons of switching to synthetic transmission fluid in a higher-mileage vehicle. Later, Harlan Siegel of Launch Tech USA joins the program to talk scan tool technology, diagnostics, and how today's technicians depend on advanced equipment to solve increasingly complex vehicle problems.

The phones stay busy with a caller seeking advice on a troublesome 2014 Ford Focus transmission, one of the most talked-about drivability issues of its era. Ron also answers an email regarding excessive oil consumption on a 2007 Toyota RAV4, explaining the causes, potential repairs, and what owners should know before making decisions.

It's a look at how automotive repair continues to evolve as today's vehicles rely as much on software and electronics as they do on nuts and bolts.

Ron starts the hour with not one, but two Repair of the Week stories that left even him shaking his head. Sometimes the hardest part of fixing cars isn't the diagnosis—it's understanding how they got into that condition in the first place.

Ron then takes a call on a 2004 Pontiac Vibe and answers a variety of maintenance and repair questions before welcoming special guest Jerry Ostalecki from GetGibbs.com to discuss lubricants, corrosion protection, and keeping equipment running longer.

Later, a listener with a 2007 Toyota Matrix calls after removing and reinstalling a factory CD player only to find it no longer works, leading to a discussion about electronics, wiring, and the surprises that can occur when taking modern vehicles apart. Ron also answers an email regarding a software issue on a Ford F-150 and explains why today's vehicles often require as much computer knowledge as mechanical skill.

All that and more this week on Ron Ananian, The Car Doctor.
