Why does the electric car display 'M' and jerk when accelerating without moving?
2 Answers
The reasons why an electric car displays 'M' and jerks when accelerating without moving are as follows: Worn or deformed throttle switch causing poor contact: Check if the throttle switch is worn, deformed, or impacted, leading to poor contact. Loose battery socket output terminal connection: The battery socket, which is the output terminal connection, may be loose. This usually occurs after the vehicle experiences various levels of vibration and may return to normal after another external vibration. Brake switch not fully reset: The brake switch, also known as the parking brake, may not be fully reset, causing intermittent operation. This can be resolved by resetting the handle or brake.
When I was driving, I encountered an issue where the electric car displayed the M gear, didn't move when I pressed the accelerator, and also shook. First, I need to understand that the M gear is usually the manual mode. If you selected the wrong gear, the car would get stuck there. No response when pressing the accelerator pedal might be due to a malfunction in the electric motor control system, such as a faulty sensor or software issue, failing to receive the acceleration signal. As for the shaking, it's likely caused by the drive wheels bouncing, possibly due to unbalanced wheels, loose suspension, or unstable battery power causing oscillations. In such cases, don't force the car to drive, as it might damage the motor or electronic components. I recommend pulling over immediately to check if you accidentally shifted to M gear, try restarting the vehicle or switching to automatic mode. If that doesn't work, contact a professional repair shop right away to avoid breaking down on the road. Regular maintenance of the electric vehicle's drive system can prevent such issues, so don't ignore minor problems.
