It’s Not Your Dad’s Oldsmobile: How Automotive Repair Has Changed

Watch Now

Automotive repair isn’t what it used to be—and that’s not a bad thing. From advanced vehicle diagnostics and OEM scan tools to ADAS calibration and electronic brake systems, today’s cars require a completely different level of precision than they did even ten years ago. In this episode of the C&C Auto Show, the crew breaks down how modern technology has reshaped everything from check engine lights to collision repair.

We also tackle real-world questions about EVAP codes, airbag lights, coolant changes, transmission services, brake rotor replacement, Kia theft prevention updates, compact jump starters, and what a fair labor rate really means. If you’ve ever wondered why a shop insists on diagnostics—or why they won’t “just replace the part”—this episode explains why proper testing saves money and protects your safety.

Listen in or watch the full episode to stay informed, avoid costly mistakes, and better understand how today’s vehicles really work.

Questions and Answers

Key takeaways from this episode on modern vehicle diagnostics, collision repair, and how automotive service has changed over the years.

Why won’t some shops replace a fuel filter on newer vehicles?

Many modern gas vehicles no longer have a traditional serviceable fuel filter. The filter is often integrated into the fuel pump assembly inside the tank and designed to last the life of the vehicle. Replacing it unnecessarily can mean major expense without benefit.

What’s the difference between a code reader and a real diagnostic scan tool?

A basic code reader only pulls stored trouble codes. A professional scan tool communicates with all vehicle modules, runs active tests, and accesses secure gateways. Proper diagnostics identifies the root cause instead of just replacing parts based on a code.

Why shouldn’t I replace a part just because a code mentions it?

Trouble codes often indicate a system issue, not a failed part. For example, an O2 sensor code may be caused by a lean or rich condition rather than a bad sensor. Replacing parts without testing can waste hundreds of dollars.

What does an EVAP “high purge flow” code usually mean?

It commonly points to a faulty purge valve in the evaporative emissions system. The purge valve controls fuel vapor flow from the charcoal canister into the engine. While it’s often the culprit, proper diagnostics confirms the repair before replacing parts.

Why are pre-scans and post-scans important after a collision?

Modern vehicles have multiple sensors and safety systems that may not trigger a dash warning light. A pre-scan identifies hidden codes before repairs begin, and a post-scan ensures everything—including ADAS features—is calibrated and functioning properly.

Should an AC condenser be replaced if the fins are bent but it still blows cold?

Even minor damage can lead to future leaks or reduced efficiency. If the condenser was impacted in a collision, replacement may prevent future failures that would require disassembling the front of the vehicle again.

Why don’t shops turn brake rotors like they used to?

Modern rotors are thinner and designed to wear along with the brake pads. Once they reach discard thickness, they should be replaced rather than resurfaced. Replacement rotors are also more affordable than they were years ago.

What does a red “Service Airbag” light mean?

A red airbag light means the supplemental restraint system is disabled. If the light is on, airbags may not deploy in an accident. The vehicle should be scanned with proper diagnostic equipment to identify and repair the issue.

Why were certain 2021 Kia models easier to steal than 2022 models?

Many 2011–2021 models lacked engine immobilizers. Starting in 2022, immobilizers became standard equipment, significantly reducing theft risk. The immobilizer prevents the engine from starting without the correct key signal.

What should I consider beyond a shop’s hourly labor rate?

Focus on the total repair cost, parts quality, warranty, and technician expertise—not just the hourly rate. A lower rate doesn’t always mean better value. Proper diagnostics and quality repairs can save money long term.
