keep getting random drive system failures with a slow driving caution due to limited stabilty control, i had this not long after i purchased the car and a faulty steering angle sensor was blamed and subsquently reset by the dealer but now its happening again, also getting random parking light failures too, anybody got any ideas?, car is due to go back on april 7th to have the back window replaced because the element is causing interference to the radio, thankfully this is being done under warranty
