What Are the Reasons for a Sudden Failure to Start an Electric Vehicle?

Here are the reasons why an electric vehicle may suddenly fail to start: Gear not in P position: Some owners forget to return the gear to the P position before turning off the vehicle, which can prevent the vehicle from starting the next time. This is the vehicle's self-protection mechanism. Simply returning the gear to the P position and pressing the brake will allow the vehicle to start normally. Therefore, always ensure the gear is in the P position before exiting the vehicle. Steering wheel anti-theft mechanism activated: If the steering wheel is forcibly turned more than 30° while the vehicle is off, it may trigger the anti-theft system. In this case, the vehicle will not start, and the steering wheel will be completely locked. To resolve this issue, you can perform a re-lock and unlock cycle on the vehicle. Generally, when the vehicle detects the key signal, the steering wheel anti-theft system will automatically deactivate.

What Should Beginner Drivers Pay Attention To?

Here are some precautions for beginner drivers: 1. Pay attention to speed: As long as you are not on the highway, it is advisable for beginners to maintain a stable speed of around 60, which helps with control. 2. Observe the rearview mirrors more often: The rearview mirrors allow you to monitor the road conditions on both the left and right rear sides of the vehicle, especially when changing lanes, reversing, or overtaking, where the rearview mirrors play a crucial role. 3. Maintain a safe distance: Beginner drivers tend to follow too closely. If the car in front brakes or cuts in, beginners often react by immediately hitting the brakes, and sometimes excessive nervousness can lead to oversteering, causing accidents. Therefore, keeping a safe distance from the car in front is crucial. When someone cuts in, slow down appropriately to yield. 4. Use lights correctly: Do not turn on the hazard lights randomly. Turn on the side marker lights at dusk, and fog lights should only be used in foggy conditions with poor visibility.
