NHTSA Complaint #11447363 — 2020 TESLA MODEL Y

I think regenerative braking makes the Tesla Y fishtail and swerve when driving in snow, ice or slippery surfaces when you decelerate or go downhill. The regenerative brakes cause the car to suddenly brake in snow or ice. If you brake suddenly in snow in a normal car, you may swerve, and this swerving is worse if the car is turned slightly. A friend swerved suddenly going downhill in WA in a snow storm. He recovered by lightly touching the accelerator. My Tesla Y spun 90 degrees when I took foot off accelerator in snowstorm in RI and I was able to recover. Minutes later on expressway at 25 mph, I took foot off accelerator and the car spun 180 degrees and hit a guard rail. In the Chevy Bolt owners manual, under winter driving, the first bullet point they make is to put the car in D--which turns off regenerative braking. You can reduce the amount of regenerative braking on a Tesla, but you can not turn it off. Under driving in winter on the Tesla on the website, there is no mention of reducing the regenerative braking in snow or ice. I think any EV with regenerative braking is at risk of spinning out in snow, ice or on slick surfaces.
