The sound you are hearing is related to the tires moving from what it sounds. The first thing to inspect is proper tire inflation. A bad brake, warped caliper or rotor, or issues with the parking brake can all cause noises related to the tires rotating.

There are a number of different reasons your serpentine belt might make such an unpleasant noise when you start your car, but the most common cause is simply wear and tear. After time and use, the rubber belt becomes brittle, which can cause it to crack and slip, creating that shrill sound.

When your smooth-running car or truck suddenly sounds like an angry tractor, chances are good that something within the exhaust system is to blame. The problem could be a broken exhaust manifold, or it could be farther downstream in the exhaust system’s pipes and its connection to the muffler.

Over time, wear and tear can take a toll on the belt and the pulleys, which often results in that high-pitched chirping sounds when you start the car and accelerate. The most common serpentine belt problems include: A worn belt can, therefore, begin to slip, which is one of the causes the squeal.

A loud noise coming from your vehicle when you accelerate, particularly one that sounds similar to a lawn mower is most likely due to an exhaust system leak.

Signs that Your Car’s Engine is Flooded

1. Smelling gas: If you smell a gas-like odor, this could be a sign of a flooded engine.
2. Emission color: If it is a darker smoke, this could also be a sign that your engine is flooded.
3. Trouble starting: Your car might have trouble starting up if the engine has excess fuel.

If you hear a whine or the sound goes fuzzy when you hit the gas, your alternator is probably failing. If the vehicle won’t crank or start but the headlights are still working, look to problems with the starter or other parts of the engine.
