Just got back from a trip down south (M5, M40, M25, M23) used TACC most of the way there and back, some short stints of autosteer but not much. On the way down all was fine, but coming back up the M40, once I got past High Wycombe the TACC started suddenly dropping its max speed from 70mph to 50 or 55mph everytime I went past a junction turn off, pretty consistently at the hard shoulder apex of the junction. Did it both in inside lane and middle lane (don't remember it doing it in outside lane). Must have done it half a dozen times at least. Has anyone else experienced this?
I found some old threads from the US but nothing recent or in the UK.
Only seemed to do it on M40 northbound, no other motorways I travelled on today. It was getting dark/had gone dark (but it was dark on the M5 bit too and I didn't have the issue). May be related that I've noticed my GPS seems to be off too? Only noticed past few days, I'm either on the very left edge of whatever road or in some cases I've been 20m off to the left of the road driving through houses - it's been bad enough at times that the routing has been constantly changing to try and find me. Car (2021 LR) was in SC for a new rear windscreen just over a week ago (heater elements damaged from factory) - could they have damaged the GPS and affected the TACC? Don't know where the GPS is located...
Sorry for the rambling post but I've had a long drive to ponder all contributing factors and possibilities!
