NHTSA Complaint #11481317 — 2021 TESLA MODEL Y

Autopilot was on during a light rain event where I was traveling less than the posted speed limit on the I95 northbound Highway. The autopilot appeared to force the car to abruptly jolt the steering wheel/tires, causing a slip/ hydroplane of the front end which forced the car into a left/sideways slide across the highway. The car slid sideways for about 100 feet or so before going straight into the concrete divider along the Highway (front driver side initial impact, then rear driver side 2nd impact). Control could not be regained with the vehicle. Steering did not work (tried to correct the path), it felt as if brakes did not slow the vehicle as the car approached the divider. Autopilot was fully engaged and lane keeping was active… with at least one hand on the steering wheel and moderate level of attention to the road. I must say I had likely became over-reliant on the autopilot. No warning was provided to me as, prior to the incident. A similar hydroplane problem can also be seen on a YouTube video posted online for the same model car. I experienced the same outcome as the other vehicle except I hit a divider after crossing lanes. I am however very pleased with how well the car handled the impact and how well the airbags went off, although also unfortunate- I do feel like the car may have been partially responsible for the accident itself.I have experienced a few prior occurrences where the car will jerk the wheel when in autopilot to keep or find a lane, even with hands on the wheel and full attention facing forward.
