Why does an electric car make noise for no reason?
2 Answers
Electric cars may produce noise for no apparent reason due to the following factors: 1. Doors not properly closed: This includes not just the doors but also the engine hood or trunk. When any of these components are not securely shut, the car's alarm system may activate. If left unaddressed, the alarm will continue to sound until the car battery is drained or the door is properly closed. 2. High trigger sensitivity: Loud noises or vibrations can also trigger the car alarm. If the alarm is overly sensitive, there is a sensitivity adjustment button on the vibration sensor of the anti-theft alarm that allows for fine-tuning.
I've been driving this electric car for a few months now, and from time to time, I hear some inexplicable noises, like sudden clicking sounds or whirring noises. At first, I thought it was nothing, but hearing them so often is starting to make me uneasy. Upon closer consideration, it might be the fan of the battery thermal management system operating, or vibration caused by some insulation issues in the motor. It could also be some external stones stuck in the gaps of the undercarriage. The last time I listened carefully in the garage, the sound seemed to be coming from underneath the car. I tried restarting the vehicle and updating the software, which sometimes made the noise stop for a while. However, this isn't a minor issue; if not addressed properly, it could affect driving safety. I immediately scheduled an appointment with a repair shop to check the wiring and connectors, and also asked the mechanic to see if the braking system isn't properly coordinated with the regenerative function. I suggest all electric car owners pay attention to these details and not wait until major problems arise to regret it.
