Failing to prepare your vehicle for winter can lead to various issues, including battery failure, engine damage, and reduced visibility due to worn wipers. Cold weather significantly reduces battery efficiency, making it harder to start your car. Low tire pressure and worn treads can compromise safety on icy roads, while road salt can corrode your vehicle's underbody. Drivers in Minnesota, where winters are particularly harsh, are encouraged to take proactive measures to avoid these risks and ensure their vehicles are ready for the season.
