The Car Doctor - 7/8/23 - Rough Shifting Tahoe

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/a56f27bd-5675-462a-b1e3-b0390151de9d/transcript

Ron Ananian, The Car Doctor - Hour 1 - September 5, 2026

A 2020 GMC Denali arrives at R\A Automotive on a tow truck with an intermittent no-crank—and a history that would make any mechanic stop and think. Nearly three years, five different shops, multiple starters, and the same problem keeps coming back.

Ron starts where every diagnosis should start: at the beginning. Working with GM expert Ernesto through the OPUS IVS diagnostic platform, Ron separates clues from conclusions, uses factory service information and pattern-failure knowledge, and begins proving what the problem ISN’T. The trail eventually leads to a loaded voltage-drop test, a questionable negative battery cable, and a starter-solenoid connection that has seen its share of previous repairs.

It’s a real-world lesson in why replacing parts isn’t the same as diagnosing a car—and why sometimes the most valuable question a technician can ask is: What have I proved right, and what have I proved wrong?

Also this hour: when should you get a wheel alignment, why a car can be out of alignment without pulling, an A/C system that cools until the Florida heat arrives, and why guessing at refrigerant charge can create more problems than it solves.

Real calls. Real cars. Real diagnostics. Ron Ananian, The Car Doctor.

Five Shops, Multiple Starters, One GMC Denali

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/5ee951f1-7c62-4b6d-b8b1-b4bc015b722e/transcript

Ron Ananian, The Car Doctor - September 5, 2026 - Hour 1

A 2015 Dodge Durango arrives on a flatbed over the weekend with a crank-no-start. The tow-truck diagnosis? Fuel pump.

Maybe?!

By Monday morning, the Durango starts perfectly—and that’s where the real diagnosis begins. Rather than throw a fuel pump at it, Ron goes back to basics: codes, fuel pressure, fuel volume, current draw and finally a thermal imager. That’s when one electrical connector starts telling the story, climbing past 160 degrees.

The fuel pump wasn’t the problem. A failing connection in the fuel-pump circuit was.

Then comes problem number two: Chrysler’s apparent solution involves a wiring harness costing roughly $3,200. Ron keeps digging through service information, part numbers and cross-references until he finds the connector needed to make the repair for under $200.

Same vehicle. Same failure. Completely different repair.

Also this hour: a listener with a 2020 Honda Odyssey that intermittently loses electrical power, why a battery can test “good” and still deserve a closer look, the importance of loaded voltage-drop testing, and a 2004 Cadillac SRX presenting a different challenge—what do you do when the parts you need simply aren't available?

The lesson? A symptom is a clue, not a conclusion. Test the basics, prove what's good, find what's bad—and sometimes, think outside the box.

The $3,200 Wire Harness That Didn’t Need To Be

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/0af2a3e1-95e9-42d1-b67f-b4bc015ae7fe/transcript

Ron Ananian, The Car Doctor - August 29, 2026

How many scan tools does it take to fix one car? Sometimes more than you think.

Ron Ananian, The Car Doctor, takes you into the service bay with a 2022 Honda HR-V that came in for routine maintenance and turned into a lesson about just how complicated modern auto repair has become. After service and resets, the TPMS and traction-control warnings wouldn’t cooperate. Multiple aftermarket scan tools couldn’t complete the necessary calibration—but access to the Honda factory-level tool finally got the job done.

Ron explains why today’s independent repair shop needs more than one scan tool, why factory-level access is becoming increasingly important, and why scan-tool manufacturers need to do a better job of telling technicians the exact conditions required before a calibration or reset can succeed.

Also this hour: Tom tries Ford’s new mobile oil-change service and asks whether convenience can really replace putting a vehicle on a lift in a properly equipped shop. A caller battles a terrible interior odor after an ozone-machine treatment, Ron explains permanent diagnostic trouble codes, and there’s an update on the 1972 Monte Carlo.

Finally, Ron looks at a 95,000-mile used Hyundai for a customer and raises an increasingly important question: With the price and complexity of today’s used cars, is an extended warranty becoming part of the cost of buying one?

Modern cars are complicated. Having the right tool—and knowing how to use it—can make all the difference.
