Loud Engine Noise During Car Acceleration
3 Answers
The causes and solutions for loud engine noise during car acceleration are as follows: 1. Engine issues: A hissing sound from the engine, similar to steam or air escaping, usually indicates a rapid loss of power. When pressing the accelerator, you may notice poor acceleration, lack of power, and a hysterical noise from the engine. This is most likely to occur when the engine is hot, cold, or low on oil. 2. Exhaust system problems: Blockages in the exhaust system, vacuum tube leaks, or breaks. Loud noises coming from the exhaust pipe, sometimes similar sounds from the front section, mainly indicate issues with the exhaust system. Check if the exhaust pipe is cracked.
Last time when I accelerated my compact car, the engine noise suddenly became louder with a roaring sound that startled me. I thought the engine was done for, so I rushed to a nearby repair shop. The technician checked and said the oil was nearly depleted, causing increased friction and noise due to insufficient lubrication. After changing to new engine oil, acceleration became quiet and smooth immediately. Now I check the dipstick monthly and use a good brand of oil—saving money and giving peace of mind. Loud noises might be minor issues, but delaying could damage core engine components like pistons or crankshaft wear. I recommend novice car owners develop basic inspection habits—don’t be afraid of the hassle.
I've driven many cars, and there are quite a few common reasons for loud acceleration noises. A loose or aged belt can squeal—I've experienced it myself, where a high-pitched noise during acceleration was fixed by replacing the belt. Exhaust system leaks are also common, with a whooshing sound becoming more noticeable when accelerating. A simple self-check: first, listen to locate the sound—hissing from the front often points to belt issues, while a low rumble from the rear suggests exhaust problems. But don’t just guess; safety first—don’t force it. Low oil levels or a clogged air filter can also worsen the noise. Timely checks can prevent minor issues from turning into major repairs.
