I drove my first road trip from Dallas to West Texas this past weekend, and experienced numerous instances of sudden, rapid deceleration (e.g. an up to 20 mph decrease in 2 or 3 seconds) when using Cruise Control (TACC), a problem I believe is widely called "phantom braking" (PB). I did not experience it until late afternoon on day-one of the trip, when the sun was lower in the sky and I was driving straight towards it. Lots of glare from the road. I disabled TACC.
I continued my trip early the next morning and this time PB started happening when the sun was behind me. I think it would be accurate to say that PB tended to happen more frequently when the only cars ahead of me were far in the distance or non-existent. Most surprising of all, PB happened a few times on a stretch of newly completed asphalt highway, black with fresh markings, straight and relatively level, no cars in sight.
Having skimmed various posts here about PB I wonder if there's a pattern. Does PB tend to happen when there are few or no cars in the near field of view? (Who'd of thunk that the "wide open road" would be a problem for a Tesla?!) More importantly, is it ever going to be fixed?
A tangential comment. Autosteer is a big disappointment. My wife's RAV4 Hybrid lane assist works far, far better. I can drive for many miles with it enabled, and provided I warn it with a turn signal about a coming lane change, it's flawless. With my new Tesla 3 RWD (August '23) Autosteer turns off frequently unless the road is straight with no changes in the road or markings. So primitive! Tesla should hire a Toyota engineer.
