I had my car in yesterday as the emergency braking has happened 6 times now, bus almost went in to the back of my the last time so booked it in. MG said they couldn't fault it, had it at the garage from 8:30 and didn't look at it until 15:00. I have a tracker fitted to mine and they took it out for a drive for all of 2 mins. Basically said if it persists then I'd have to take it back, not sure at what point they'll do something though, when a car actually rear ends me? They also said there was a recall for the software but they didn't tell me the details of that.
It looks like they've put me on R30 now though, I'm fairly certain I was on R33 before but cannot confirm, now my screen is less responsive but the LKA is certainly less prominent.
