About 7 percent of car crashes are caused by some kind of vehicle failure, with tire degradation and brake system failures topping the list, according to the National Motor Vehicle Crash Causation Survey from the National Highway Traffic Safety Administration. But tire and brake failure aren't the only types of vehicle problems that can lead to accidents - engine, steering system and suspension failures also cause crashes. Here are common car noises people hear and what they could mean:
- Humming or groaning: When you hear humming while driving at faster speeds, it's a sign there probably is some wear on your tires, which can lead to serious issues. It could be located on the insides of your tires, which is hard to diagnose on your own, but not having it checked is a risk, because the steel belts in the tire might be coming apart.
- Growling: This noise could change or even go away when you turn the wheel, but it is usually caused by a defective front wheel bearing. The change in noise could be a result of the shift in the weight of the car as you turn.
- Whining and creaking: You might hear these noises backing up or turning. It could be the result of a ball joint or tie rod seizing up.
- Squeaking: This can be a high-pitched, steady annoyance that lets you know it's time to get your brake pads checked or replaced.
- Grinding: This sound means two pieces of metal are touching when they shouldn't be. This sound could be a multitude of things: brakes, powertrain, suspension or something else. Whatever the case, a grinding sound means you need to get your car checked out as soon as possible.
- Hissing: A hissing sound might occur after you turn off your ignition and can sometimes be followed by smoke from under your hood.
