Tire Squeal: This is the most common cause of screeching noises when accelerating. It occurs when the tires lose traction and start slipping on the road surface. This can happen when you accelerate too quickly, especially from a standstill. Worn or low-quality tires are more prone to squealing.
Engine Issues: Various engine problems can also lead to screeching sounds under acceleration. For instance, a faulty serpentine belt, which drives various accessories in your car's engine, can produce a squealing noise when it's worn or damaged. A failing alternator, which generates electricity for your vehicle's electrical system, can also make a screeching sound.
Driveline Issues: Screeching noises might be caused by issues with the driveline components that transfer power from the engine to the wheels. Worn or damaged universal joints (U-joints) or constant velocity (CV) joints in your car's driveshaft can produce screeching sounds, particularly when accelerating or turning. Faulty bearings in the transmission or differential can also cause similar noises.
Exhaust System Problems: A leak in the exhaust system can create a high-pitched screeching sound. Check for loose or damaged exhaust components like the exhaust manifold, catalytic converter, or muffler.
