Since the latest software update, my "max speed" on autopilot is randomly changing (both down AND up) when driving on the highway where the speed should of course be fixed. This is happening again and again on the same drive. I was on the LIE today (55MPH, no construction etc) and the set speed dropped from 65 to 35 without warning and without me touching the control wheel. VERY DANGEROUS! It happened at least a dozen times on my drive, I even took a video. It also jumped up above its set point without my input. I was also noticing (although not correlated to the speed changes) that the car was getting the speed limit wrong for the highway multiple times. Is this a known issue with the new software? I also had my steering wheel replaced a month ago, could this be related?
