Why does a Mercedes-Benz car not move when the accelerator is pressed after starting?
2 Answers
The reason why a Mercedes-Benz car does not move when the accelerator is pressed after starting is due to clutch slippage. Below are the specific details: 1. Manifestation: Clutch slippage is mainly manifested as the vehicle's speed not increasing with the rise in engine RPM during acceleration, and the engine's power not being fully transmitted to the driving wheels, resulting in weak driving force, especially noticeable when going uphill. 2. Causes: The main reasons for clutch slippage are insufficient friction of the clutch friction plate; shifting gears prematurely or disengaging gears before the clutch is fully engaged; prolonged driving in a semi-clutch state or coasting with the clutch pedal pressed; and abnormal wear of the clutch plate caused by abruptly pressing the accelerator when shifting or disengaging gears is not fully completed.
I've been driving a Mercedes-Benz for many years and encountered an issue where the car wouldn't move after pressing the accelerator upon starting. It happened at a highway entrance, which gave me quite a scare. The main cause turned out to be an automatic transmission failure, such as low fluid levels or internal wear, leading to power transmission failure. Electronic systems can also cause trouble, like a faulty accelerator pedal sensor or issues with the ECU control module, preventing signals from reaching the transmission. Forgetting to release the parking brake is a common mistake among beginners; if the electronic parking brake on a Mercedes isn't fully released, pressing the accelerator won't move the car. The first step is to check if the parking brake is completely released—don't ignore the warning light on the dashboard. Transmission fluid should be changed regularly, with checks every 40,000 kilometers to avoid clogging from deposits. If the problem persists, seek professional diagnosis immediately. Mercedes cars are technically sophisticated, so avoid DIY repairs—safety comes first.
