A failing turbocharger can produce a high-pitched whine as the turbines spin at high speeds. Similarly, a low power steering fluid level can cause a whining noise when turning the steering wheel.
Rattling Sounds
Rattling noises can originate from various sources. Loose heat shields, worn-out belts, or issues with the exhaust system are common culprits. A thorough inspection is crucial to pinpoint the exact source of the rattle.
Knocking Sounds
Knocking sounds are often a sign of serious engine trouble. These sounds can indicate problems with the engine’s internal components, such as worn bearings or piston slap. If you hear a knocking sound, it’s crucial to have your car inspected by a qualified technician immediately.
