What Causes the Acceleration Jerking Issue in Mercedes S350L?
1 Answers
Mercedes S350L acceleration jerking issue can be caused by the following reasons: New Car Break-in Period: New cars or recently replaced brake discs and pads require a break-in period, during which some abnormal noises are inevitable. These noises usually disappear after driving a few hundred kilometers. ABS System Activation: During emergency braking, the brake pedal may produce continuous "thud" sounds and sometimes a pulsating sensation. This indicates ABS system activation and is normal. In this case, press the brake pedal firmly all the way down, but this only applies to vehicles equipped with ABS. Metal Hard Spots on Brake Pads: Brake pads may contain small metal particles that produce sharp, screeching noises when lightly braking. This issue can be resolved by slamming the brakes several times, removing and resurfacing the brake pads, or replacing them with higher-quality ones.
