Carmaker won't cover costs of ruined axles and motor.
Electric vehicles, like the ones built by Tesla, work remarkably well in the snow. Because electric motors have very low inertia, meaning they can be sped up or slowed down quickly, advanced traction control systems are able to put down power even in slippery conditions. From there, having all-wheel-drive and/or snow tires will still improve a car's ability to drive in deep snow. But a YouTuber decided his Tesla Model 3 could be an even better snow vehicle if he equipped it with tracks.
The results of this experiment were pretty fun to watch, though one of the tracks kept skipping teeth during the test. This wouldn't have been a huge issue but now the YouTuber is fighting with Tesla after his car's drive unit and axles were damaged, and the company refused to cover it under warranty.
Michael posted a picture on Twitter of his car on a flatbed with the caption:
"Tesla voided my warranty on a 3 month old 2020 Model 3 and jabbed me with a $4,500 bill on a failed motor." The tweet also tagged Tesla and company CEO Elon Musk. Tesla responded by telling the YouTuber that the "snow track with 50% gear reduction caused excess heat on the drive unit 5mph and less." Some Tesla enthusiasts have defended the company on this matter while others believe the motor shouldn't have failed so easily, even if it was modified.
