Ron Ananian, The Car Doctor - January 31, 2026 - Hour 2 - Batteries, Start-Stop Tech, CVTs & Cold-Weather Car Problems
Cold weather exposes weak links in today’s vehicles, and this hour of Ron Ananian, The Car Doctor breaks them down. Ron explains why modern car batteries should be replaced every 4–5 years—even if they still test good—and why where you buy a battery matters as much as the warranty.
He also dives into start-stop systems and CVT transmissions, explaining how they work, why oil and fluid maintenance is more critical than ever, and what drivers should realistically expect for longevity.
Plus, real-world winter diagnostics, including a no-heat-at-idle problem, air-bound cooling systems, and how to diagnose issues step-by-step without guessing. Practical advice, shop-floor experience, and straight talk for anyone keeping a car past the warranty.
