What is the buzzing sound from the front of a Tesla after turning off the engine?
2 Answers
Tesla's front buzzing sound after turning off the engine is the normal noise made by the three-way catalytic converter due to overheating. Below is an introduction to Tesla: 1. Vehicle Positioning: Tesla is a medium-sized electric vehicle with a wheelbase of 2875 mm, and its length, width, and height are 4694 mm, 1850 mm, and 1443 mm respectively. 2. Power System: Tesla offers both rear-wheel-drive and four-wheel-drive models. The four-wheel-drive models are dual-motor vehicles, while the rear-wheel-drive models are single-motor vehicles. The total power of the four-wheel-drive Model 3's motors is 340 kW, with a total torque of 639 Nm. The rear-wheel-drive model's motor has a maximum power of 202 kW and a maximum torque of 404 Nm. 3. Battery: Tesla uses ternary lithium batteries across its entire lineup, which have higher energy density and are lighter in weight.
When I first got my Tesla, I was also curious about the buzzing sound from the front after turning it off, like a little bee. At first, I thought it was some kind of malfunction, but later I figured out that Tesla's battery still needs to cool down after parking, and the fan automatically turns on to prevent overheating and extend battery life. This is completely normal. I've experienced the fan running for a few minutes after getting out in the summer, but the sound isn’t loud and stops after a minute or two. If the noise is annoyingly loud, it might be due to dirt stuck in the fan or misalignment. I suggest new Tesla owners not to panic—use the Tesla App to check the battery temperature. If the sound is unusual or frequent, schedule a service center appointment to inspect the fan or cooling system. Parking in the shade can also reduce the chances of hearing the noise, since electric cars have unique cooling mechanisms. The more you understand, the more confident you’ll feel driving.
