I traded my classic Model S for an X with HW2, delivered 3 weeks ago. I had an incidence of dangerous sudden acceleration nearly caused an accident. This may be specific to new cars with HW2. When cruise control of my Model X was disengage (but not turn off), it still remembered the previously set speed, and when the cruise control level flipped up, the vehicle accelerated to the speed. Two weeks ago, when I slowed down to about 20 mph to make a left turn, I accidentally flipped the cruise control level up (the turn signal level and cruise control lever are closely placed, and I only had the car for a week), the vehicle accelerated powerfully to the previously set speed (60 mph). I almost hit the car in front of me. If it happened in my garage or a parking lot, it would be one of those reported incidences. I hope the new HW2 software update will solve the problem.
