Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 30,000 mi

Replace the cabin air filter every 30,000 miles, sooner in dusty climates. Located behind the glove box on most Toyota and Lexus models.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Serpentine / Drive Belt Inspection

Every 60,000 mi

Inspect the serpentine belt and tensioner every 60,000 miles. Toyota uses long-life EPDM belts that rarely fail before 100,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165

DIY

~$20–$50

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.

Timing Chain — No Replacement

On condition / lifetime

Toyota's 2AR-FE, 2GR-FKS, A25A-FKS, and most Toyota engines built since 2010 use a timing chain rated for the life of the engine. No scheduled replacement.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Pro only

Timing chains are normally lifetime. Listen for rattle on cold start — that's the actionable signal. Replacement is major work, quote separately.

Occupant deaths in fatal crashes (FARS)

18 crashes 2010–2024

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
