When you think of rust on a car, your mind probably jumps to images of vehicles in snowy, road-salted cities. But what about San Diego, where the sun shines most of the year, and rain is rare? As one of the most trusted auto repair shops in San Diego with over 30 years of experience, FTS Auto Repair is here to answer a common question we get: Do I really need to worry about rust in a dry coastal climate?
The short answer is yes—just not in the same way as drivers in wetter climates.
Why Rust Still Happens in San Diego
While San Diego is known for its dry, temperate climate, we’re also surrounded by the Pacific Ocean, which brings salty air and humidity, especially closer to the coast. Salt-laden air can accelerate the oxidation process, leading to surface corrosion over time—even without snow or rain.
This means that car rust in San Diego is often related to coastal exposure, poor maintenance, and aging components. Vehicles left outdoors near the beach, especially overnight, are more susceptible to corrosion, particularly on undercarriages, wheel wells, and exhaust systems.
Common Areas Where Rust Can Form
Even in San Diego, rust can quietly develop in these parts of your vehicle:
- Undercarriage – The frame and suspension components are most vulnerable.
- Brake and fuel lines – These metal lines can corrode, leading to dangerous leaks.
- Wheel wells – Especially if road debris and moisture are allowed to build up.
- Door seams and trunk edges – Areas where water can sit unnoticed after a wash or rain.
The Importance of Preventative Maintenance
At FTS Auto Repair, we emphasize the importance of scheduled maintenance and preventative inspections to catch early signs of corrosion. Regular oil changes, tire rotations, and undercarriage inspections allow our technicians to spot and address rust issues before they turn costly.
Rust doesn’t just ruin your vehicle’s appearance—it can also compromise your safety. Rusted brake lines, weakened suspension parts, and corroded structural components can all put you at risk on the road.
How to Prevent Rust in San Diego
If you live in San Diego and want to keep your car rust-free, follow these tips:
- Wash your car regularly – Especially the undercarriage, to remove salt and grime.
- Avoid parking near the beach overnight – Or use a high-quality car cover to protect from salt air.
- Apply rust-proofing sprays – Especially to areas vulnerable to corrosion.
- Keep drains clear – Check door and trunk drain holes to prevent standing water.
- Get regular inspections – Our team at FTS Auto Repair can spot rust early and recommend protective treatments.
How Rust Can Affect Resale Value
Even in dry climates, visible rust or corrosion underneath the car can lower your vehicle’s resale value significantly. Dealerships and private buyers often inspect the frame and undercarriage before purchase. Taking steps to prevent rust is not only about safety—it’s also about preserving your investment.
If you’re considering selling or trading in your car in the next few years, maintaining a rust-free vehicle can lead to higher offers and a quicker sale.
