The Hawthorne driver's seasonal checklist

South Bay driving is uniquely hard on a car. Salt air, stop-and-go on the 405, and triple-digit summer heat add up. Here's the seasonal rhythm we recommend for our regulars.

Spring (Mar–May)

Cabin air filter, A/C performance check, and a brake inspection before summer road trips. Coastal pollen plus spring allergies make a fresh cabin filter the cheapest comfort upgrade you can buy.

Summer (Jun–Aug)

Cooling system pressure test, coolant condition check, battery load test (heat kills batteries faster than cold), and tire pressure adjustment for hot pavement.

Fall (Sep–Nov)

Oil change with fresh full-synthetic, wiper replacement before the first rain, and a full underbody inspection for corrosion from coastal moisture.

Winter (Dec–Feb)

Brake fluid moisture test, alignment check after a year of LA potholes, and tire rotation. We don't get snow — we get sideways rain on bald tires.
