Common Winter Vehicle Repairs and How to Prevent Them
Winter is not a season; it’s a test for your vehicle.” Cold temperatures, ice, and road salt put a strain on every part of your vehicle, turning minor issues into major headaches. In fact, Canadian winters can be so harsh that AAA reports a vehicle is twice as likely to break down during cold weather than at any other time of year. The good news? Most of these problems are avoidable with the right maintenance and preparation.
In this article, we’ll cover the most common winter vehicle repairs and how you can prevent them. Let’s keep your vehicle running smoothly while avoiding costly surprises.
1. Dead Batteries
Cold weather drains battery power faster than you might expect. At -18°C, a fully charged battery can lose up to 50% of its capacity. Combine that with higher demands on your electrical system for heating, and you’ve got a recipe for trouble.
Prevention Tip: Have your battery tested before winter hits. If it’s more than three years old, consider replacing it. Keep the terminals clean and ensure your vehicle’s alternator is charging properly. Carry a portable jump starter for emergencies—it’s a lifesaver when you’re stuck in the middle of nowhere.
2. Frozen Fuel Lines
Visibility is critical in winter, but frozen wipers and washer nozzles can render your windshield a frosty mess. Cheap wiper blades and summer washer fluid just won’t cut it.
Prevention Tip: Replace wiper blades with heavy-duty winter versions and use washer fluid rated for sub-zero temperatures. Lift your wipers off the windshield when parking overnight to prevent them from freezing in place.
3. Tire Wear and Damage
Cold temperatures cause tires to lose air pressure, increasing the risk of uneven wear or even a blowout. Add icy roads to the mix, and you’re facing some serious safety concerns.
Prevention Tip: Check your tire pressure weekly during the winter, and adjust it according to the manufacturer’s recommendations. Switch to winter tires—they’re designed to provide better traction and durability in icy conditions. Inspect your tires for cracks or wear before hitting the road.
4. Faulty Heating Systems
There’s nothing worse than a heater that fails when it’s -30°C outside. Heating system issues often stem from a malfunctioning blower motor, clogged heater core, or low coolant levels.
Prevention Tip: Schedule a system check before winter begins. Ensure your coolant is at the proper level and replace it if it’s old. Clean or replace cabin air filters to maintain strong airflow. Don’t ignore strange noises from your blower motor—they’re a red flag!
5. Corroded Undercarriage
Road salt is a silent killer for your vehicle. Over time, it eats away at your undercarriage, causing rust and weakening essential components like the suspension and brake lines.
Prevention Tip: Wash your vehicle regularly during the winter, focusing on the undercarriage. Applying a rust-proofing treatment before the season starts adds an extra layer of protection. For vehicles, inspect areas like the differential and suspension components for early signs of rust.
6. Frozen Wipers and Washer Fluid
Visibility is critical in winter, but frozen wipers and washer nozzles can render your windshield a frosty mess. Cheap wiper blades and summer washer fluid just won’t cut it.
Prevention Tip: Replace wiper blades with heavy-duty winter versions and use washer fluid rated for sub-zero temperatures. Lift your wipers off the windshield when parking overnight to prevent them from freezing in place.
7. Braking System Issues
Slippery roads require reliable brakes, but cold weather can make them less effective. Moisture in the brake lines can freeze, or road salt can accelerate wear on your pads and rotors.
Prevention Tip: Have your brake system inspected before winter. Replace worn brake pads and ensure your rotors are in good shape. If you hear grinding or squealing, address it immediately—brake failures are the last thing you want on icy roads.
