How to Spot Signs of Winter Wear and Tear on Your Vehicle
Importance of Regular Winter Vehicle Inspections
Winter can cause significant wear and tear on vehicles, particularly in the Maritime provinces of
New Brunswick, Nova Scotia, and Prince Edward Island. Recognizing these issues early can
prevent costly repairs and ensure safe driving during the harsh winter months. Below is a detailed
guide to help you spot the signs of winter-related damage, supported by Canadian statistics and
tips relevant to Atlantic Canada.
1. Rust and Corrosion
One of the most common problems during winter is rust, especially in Atlantic Canada, where road
salt is heavily used to prevent icy roads. Salt can corrode the undercarriage, brake lines, and other
metal parts of your vehicle. Regular car washes, particularly focusing on the underbody, are key to
preventing rust build-up. According to the Canadian Automobile Association (CAA), corrosion due
to road salt causes around $3 billion in vehicle repairs annually across Canada.
2. Tire Tread and Pressure
Cold temperatures cause tires to lose pressure quickly, and icy roads can lead to uneven tread
wear. Winter tires are essential in Atlantic Canada, where snow and ice are common for several
months of the year. A study by Transport Canada revealed that winter tires reduce stopping distances by as much as 25% compared to all-season tires. Always check your tread depth—if it’s
less than 4mm, consider replacing your tires to maintain grip on slippery roads.
3. Battery Health
Winter conditions in Atlantic Canada can be harsh on vehicle batteries. Cold temperatures
significantly reduce battery power, making it harder for your vehicle to start. According to CAA, a
car battery loses about 35% of its strength at 0°C and about 60% at -20°C. It is essential to have
your battery checked before winter begins to ensure it is operating at full capacity.
4. Windshield Wipers
Snow, ice, and slush from roadways can quickly degrade windshield wipers. Ineffective wipers
reduce visibility, especially during heavy snowstorms. Experts recommend replacing windshield
wipers every six months, particularly before the start of winter. In Nova Scotia and New Brunswick,
winter storms can drop several centimeters of snow in a single day, which makes having fully
functional wipers a necessity.
5. Brake System Wear
Frequent use of brakes in icy or snowy conditions can lead to accelerated brake wear. If you hear
squealing or grinding sounds when you apply the brakes, it is time for a check-up. According to
Transport Canada, heavy braking during icy conditions increases the likelihood of brake wear, as
more effort is needed to stop the vehicle on slick surfaces.
6. Fluid Levels and Oil Thickness
Freezing weather can thicken engine oil and transmission fluids, leading to engine stress and
reduced vehicle performance. Winter-grade oil is recommended to keep the engine running
smoothly. CAA advises using synthetic oils that can withstand extreme cold, especially in regions
like PEI where winter temperatures can dip well below freezing.
7. Exhaust System Issues
Salt and moisture from winter roads can also damage your exhaust system, leading to rust or leaks.
A clogged exhaust can reduce engine performance and fuel efficiency. Keeping an eye on exhaust
sounds or visible rust during winter checks can help prevent major damage. This is particularly
relevant in Maritime provinces where winter road conditions are notoriously tough on vehicle parts.
8. Heater and Defroster Efficiency
Your vehicle’s heating and defrosting systems are essential for maintaining visibility and comfort
during winter driving. A malfunctioning defroster can cause ice to build up on your windshield,
reducing visibility. According to the Canada Safety Council, a proper defroster is one of the most
important tools for safe winter driving in Atlantic Canada, where winter storms are frequent.
9. Lights and Electrical Components
Winter months mean fewer daylight hours, making fully functional headlights and brake lights
crucial. Wintry weather can weaken bulbs or corrode electrical connections, leading to dim or
malfunctioning lights. Frequent inspections of your vehicle’s lights, particularly during the darker
winter months in Atlantic Canada, can prevent safety issues on the road.
10. Suspension and Alignment
Potholes and rough road conditions are common in New Brunswick, Nova Scotia, and PEI during
the winter months. Driving over these can damage your vehicle’s suspension and alignment. Signs
of suspension issues include uneven tire wear, pulling to one side, or a rougher ride than usual.
Regular alignment checks can help protect against long-term damage caused by winter roads.
