The possible causes of this fault vary depending on the vehicle model. Below are the specific reasons: Automatic transmission models: Automatic transmission models are less likely to experience stalling, whereas manual transmission models may stall frequently due to inexperienced driving. However, it is not impossible for automatic transmission vehicles to stall; the main reason is the use of low-quality fuel, which leads to engine carbon buildup and stalling. Manual transmission models: The primary cause is excessive dust in the air, leading to the accumulation of dirt on the idle air control valve and throttle body during engine operation.

What causes the abnormal noise in GLC on bumpy roads?

Here are the specific reasons for the abnormal noise when the GLC drives on bumpy roads: 1. Check the car's shock absorbers. It's best to go to a 4S shop or repair shop and use a lift to raise the vehicle to inspect whether there are gaps in the shock absorbers or faults in the suspension. If the shock absorber is leaking oil, it may be due to a faulty oil seal gasket, and the shock absorber needs to be replaced. Generally, the service life of shock absorbers is 80,000 to 100,000 kilometers. When the car has driven 80,000 kilometers, you can ask the technician to pay attention to the condition of the shock absorbers during regular maintenance. If there is a fault, repair it in time. 2. Excessive gap in the steering tie rod ball joint may also cause abnormal noise when turning. In severe cases, there may be steering wheel shaking or tire wear, and the ball joint should be replaced at a 4S shop or repair shop promptly. 3. Excessive gap or looseness in the lower control arm. The lower control arm is an important component that maintains the elasticity of the car body and is part of the car's suspension. The lower control arm connects the axle and the frame, buffering the impact of bumpy roads on the car. Once the lower control arm fails, it should be replaced at a 4S shop or repair shop promptly.

What Causes the Abnormal Noise When Turning the Steering Wheel While Stationary in a New Car?

New cars producing abnormal noises when turning the steering wheel while stationary can be attributed to sounds from the shock absorber top bearing, the stabilizer bar, the steering column dust cover, or interference from the clock spring. Noise from the shock absorber top bearing: If a noise occurs when gently shaking the steering wheel while stationary, it is likely due to insufficient lubrication in the shock absorber's top bearing. To confirm, open the hood and listen if the sound originates from the shock absorber's top mount. Applying grease to the top bearing may resolve the issue; if the noise persists, replacement is necessary. Noise from the stabilizer bar: If the noise is not from the shock absorber, check the stabilizer bar bushings for looseness or damage. Loose or damaged stabilizer bar bushings can cause noises not only when turning the steering wheel but also when driving on uneven roads. Loose bushings can be fixed by adding shims, while damaged ones require replacement. Noise from the steering column dust cover: Inspect the steering column dust cover. A lack of lubrication in the dust cover can cause dry friction noises. Applying grease inside the dust cover should eliminate the noise. Noise from clock spring interference: If the noise comes from within the steering wheel while turning, it may be due to interference from the clock spring. Remove the steering wheel and apply grease to the clock spring. If the noise continues, replacing the clock spring is the only solution.

Can the leather under the car window be repaired?

The leather under the car window can be repaired, and the repair method varies depending on the extent of the leather damage. If it is just a small crack, you can use leather repair fluid to fix it. Lay the leather flat on a workbench, align the crack, apply the appropriate leather repair fluid, and then dry it with a hair dryer. If the crack is large, take a piece of leather or non-woven fabric that matches the softness of the damaged leather for repair. Lay the leather flat on a workbench, cut a piece of leather or non-woven fabric larger than the crack, place it under the damaged area, and bond it with leather adhesive. Finally, cover it with a piece of cotton cloth and use an iron to set it. Methods for maintaining car interior leather: Use car leather maintenance oil. Car leather maintenance oil has penetrating and moisturizing effects, providing deep and long-lasting protection for genuine leather. It keeps leather products soft and maintains their natural color, effectively preventing aging, cracking, and discoloration. It is also waterproof, mold-proof, and enhances the gloss of car leather. The application method is simple: spray or apply the maintenance oil evenly on the leather with a cotton cloth, then polish it with a white cloth. Use seat covers. Seat covers can protect car leather. As long as the seat covers are well-maintained, the car leather will not suffer significant damage. However, car owners should still regularly maintain the interior leather, clean the seat cushions, and remove surface dirt from the leather interior.
