welcome on board,wont be much help but here is my input

but issue 1 I got a couple of times and it was as far as i can see to caued by my battery being low

issue 2-get the garage to try adjust the camber and see if the wear continues

issue 3- happened to me for the first time ever this week with a message about fuel injection flashing on the dash but car never came to a standstill, just refuelled and all good, fuel level sensor may be duff if you are getting stuk so to speak after fuel level goes down to less than a quarter taken....or the fuel pump?
