With your car’s steering pulling to the left, you will want to get this checked out at your auto repair shop. When a vehicle pulls to one side or the other is raises a red flag for safety.
There are several issues that would cause a vehicle to pull to the left (or right). It could be as simple as uneven tire pressure or misalignment of the suspension to more serious issues, such as brake problems or a wheel bearing issue.
Assuming your tire pressure is fine and the wearing of the tire tread is ok, your auto tech will then be looking at the brakes and bearings for wear and possible replacement. Keeping your brakes and wheel bearings in good condition are essential for the safe operation of your car.
