Why Seasonal Homeowners Shouldn’t Let Their Car Sit All Winter
If you’re a seasonal homeowner who heads south for the winter or only uses your second home during the warmer months, it might seem easiest to leave your car behind until you return. But letting a vehicle sit unused for months at a time can lead to costly and avoidable issues.

Battery Drain and Electrical Issues
A car battery naturally loses charge over time, and cold weather accelerates that process. If your car sits untouched all winter, the battery may be completely dead by spring, leaving you with the expense and hassle of a replacement.
Tire Damage and Flat Spots
When a vehicle stays in one place for weeks or months, the tires bear the weight in a single position. This can cause flat spots, which lead to vibrations, reduced performance, and in some cases, the need for new tires.
Fluids and Engine Health
Engine oil, brake fluid, and coolant don’t age well when left stagnant. Condensation can build up inside the engine and exhaust system, leading to rust and corrosion. Over time, this can shorten the life of your vehicle’s critical components.
Fuel System Problems
Modern fuel contains ethanol, which can absorb moisture. When fuel sits in your tank for months, it can separate, leaving behind a gummy residue that clogs fuel injectors and lines. This may result in costly repairs when you try to start your car in the spring.
Rodents and Pests
An unused vehicle can be a warm, inviting shelter for mice and other small animals. They often chew through wiring, insulation, and upholstery, creating expensive damage and unpleasant surprises.
Insurance and Safety Considerations
Even if you’re not driving, keeping your car in good condition matters. A vehicle in disrepair could be more vulnerable to damage from leaks, fires, or other hazards, which may also affect your insurance coverage.

What You Should Do Instead
-
Start and drive the car regularly – even once every few weeks helps.
-
Invest in a trickle charger to keep the battery healthy.
-
Have a local caretaker or property manager run the vehicle while you’re away.
-
Consider professional winter storage where the car will be maintained and checked.
By taking a few preventative steps, you’ll avoid costly repairs and ensure your vehicle is ready to drive when you return.
