Ron Ananian, The Car Doctor - October 25, 2025 - Hour 1 - The How & Why About Automotive Maintenance - (855)560-9900 24/7 Hotline

🧠 Opening Thought: Most drivers undervalue maintenance because the car often feels the same afterward—until years later when reliability proves the payoff.

⛽ 100k vs. 200k (and 500k): Many cars can reach ~100k on oil changes alone; to reach 200k–500k, you need scheduled fluids, filters, and inspections.

🔋 Reliability Odds: Batteries past their rated life = rolling the dice. Aviation-style, time-based service intervals make sense for cars too.

🚗 Case Study—2017 Acura: Hesitation/clunk fixed by proper maintenance: ATF service (DW-1), rear diff dual-pump fluid, fuel-system cleaning; car drove noticeably smoother.

💡 Maintenance Reality: Some services improve drivability immediately; others are “insurance” that prevents failures later.

🌡️ Environment & Driving Style: Highway miles and climate dramatically affect longevity and service needs.

🛑 Auto Stop-Start: Theoretical fuel/air benefit vs. real-world costs (starters, dual batteries) and driver confidence—especially as vehicles age.

🛞 TPMS & Key Fobs (’12 Colorado): Relearn sensors after rotations; compare each sensor’s ID/pressure with BCM using a scan tool; watch for BCM or interference issues.

⚙️ GM Torque Converter Shudder: Fluid maintenance matters; sometimes requires converter/trans replacement even with regular service.

🚨 Towing Landscape: Fewer independent tow operators; have roadside assistance and a payment plan ready—tows are pricey and often cash/Venmo.
