Thanks for taking the time to read and reply. I appreciate it.
Yes, this “Road Departure Detected - Corrective Steering Applied” seems to be a pretty rare message. So much so that most people (including, I think, the folks at the Service Centre) sometimes seem to think that I’m talking about *Lane* Departure warnings. They also seem to think I’m using AP, ACC or FSD at the time, which I’m not. I imagined that since these kind of alarms seem so rare, it would be easy to a) agree that there’s a problem and b) pull the data for the relevant alarms and c) get to the bottom of it, but apparently not.
A while back I turned off Emergency Lane Departure Avoidance and at least a couple of times I’ve set Forward Collision Warning to Late but it seems to end up back at Medium somehow. I also don’t seem to be able to set it to Off, though I’ve only tried once. (Mind you, the Service Centre have also monkeyed with all sorts of things while trying to fix the alarms plus the key fob/driver profile problems so perhaps that’s why the settings have reverted.)
There’s a side of me that‘s really tempted to find an older S with just that one camera so that I don’t have to worry about so many alarms, but then I realise how ridiculous that sounds. For £80,000 (US $110,000) I should be able to get a vehicle that’s reasonably enjoyable and relaxing to drive for me and my passengers. My health’s not been great lately, but increasingly I think that I’ll take a little break, get my strength back and then restart the process of trying to get Tesla to fix this car. We don’t have the wider roads that the US enjoys, but British reviewers never seem to mention the scary behaviour my car exhibits (and surely they would, right?), so I think it must be possible to calibrate an S for fairly trouble-free UK driving.
I’ll add another post to this thread if I’m (ever) successful.
