In some cases, no abnormal symptoms will be experienced. Other systems like the transmission or ABS can cause the Check Engine Light to illuminate and lights for those systems can come on at the same time.

Next, inspect the battery health and charging status, since a compromised battery can lead to power-related problems. Pay close attention to the vehicle's display for any error messages or warnings, as these can provide critical insights into the underlying cause of the stalling. Additionally, examine your charging equipment to ensure it is functioning correctly and securely connected, as faulty charging can impact performance. Finally, reflect on any recent changes in your driving habits or conditions that may correlate with the onset of the stalling issue.

Software glitches can disrupt the vehicle's electronic systems, leading to unexpected stalls. Additionally, issues with the battery or charging system can significantly impact performance, as electric vehicles rely heavily on these components for operation.
