Has anyone noticed a significant downgrade in enhanced autopilot performance after recent updates? I have a 2020 Model 3 Performance, and have been using enhanced auto pilot (with navigation) for years on the same route and have not needed to perform any sudden interventions. There were some small interventions but I was able to comfortably correct for autopilot issues as needed. Recently, I ran into some problems I never had before that required immediate disengagement/taking over on my part.
1) While taking an offramp (Navigate on autopilot) where the freeway and the offramp split like a "Y" with no traffic around or ahead of me, the autopilot decided to abort the maneuver after already entering the offramp. It did this by jerking the steering wheel hard to the left to get back onto the freeway, attempting to cross the divider (since we had just passed the "Y" portion of the road taking the off ramp). I had to immediately force it to abort that maneuver and continue taking the offramp. There were no nearby cars at all that would necessitate this kind of abort.
2) While on the freeway with autopilot, there was traffic slowing way ahead of me. So far ahead, that if I was driving myself I could just lift off the accelerator not using the brakes and I would have slowed with a ton of room to spare. However, autopilot decided to hit the brakes so hard that the car jerked forward, and the tires squealed. I've never had the AP brake so hard to cause the tires to squeal before, and I had to press hard on the accelerator to avoid getting rear ended. There was slowing traffic ahead but it was so very comfortably far ahead that it didn't necessitate slamming on the brakes.
3) While on the freeway with autopilot, there was stopped traffic in the other lane to the right of me up ahead, but my lane was still moving. There was a car in my lane ahead of me moving slowly (perhaps 20mph), and my car was also going 20mph so speed was matched for my lane. When I got close to the stopped car (in the other lane), my car braked really aggressively (though didn't squeal the tires) and stopped my car far behind the other car (in the neighboring lane), even though my lane had no obstructions. I had to press the accelerator pretty hard to get it going again (if i let up the accelerator it would stop hard again) until i passed the car in the other lane. Once passed the other car autopilot operated normally again.
I've never had these problems before on the same roads, but only recently noticed that I have to keep taking over for situations the car used to handle just fine. Plus the takeovers I need to do are much more jarring than before. I think I started noticing this within the past 5-12 months? Did anyone else notice autopilot performing poorly all of a sudden?
