What Causes the Abnormal Noise When the Verano Starts?
2 Answers
Abnormal noise during rapid acceleration in the Verano may be due to aging engine mounts or a malfunctioning fuel injector. Aging Engine Mounts: In the mild temperatures of southern regions, coupled with the high temperatures during engine operation, it is advisable to inspect the engine mounts after six months of vehicle use. If signs of aging are detected, prompt replacement of the mounts is recommended. Fuel Injector Noise: Prolonged intervals between oil changes or insufficient engine oil can increase friction between the valves and guides, leading to amplified abnormal noises. It is recommended to contact a 4S repair shop for inspection and maintenance.
The Buick Verano makes abnormal noises when starting, which is quite a common issue. I've helped a friend solve a similar situation before. The noises usually come from the brake system or suspension components. If the brake pads are rusty or unevenly worn, they can produce a creaking sound during initial movement, especially noticeable after parking in humid conditions. Loose suspension parts like ball joints or shock absorbers can also create rattling noises during acceleration. Additionally, aged engine mounts may cause the engine to shift and hit the frame during startup, resulting in knocking sounds. It's recommended to first check the brake pad thickness and suspension fastening screws. If you can't handle it yourself, it's best to visit a repair shop for professional tool diagnostics to prevent minor issues from escalating. Delaying repairs could lead to higher maintenance costs. Starting noises affect driving experience, so early intervention brings peace of mind.
