I drive a 2019 Grandland X. I got it serviced from the main dealer in June. The following day I got "Engine Oil Pressure Fault -STOP THE CAR" fault and lost power. I stopped and started and fault was gone. This happened every second day, first thing in the morining only. I returned the car to the dealer and they said they fixed it (oil cap not secure and air getting in). However it continued and then sometimes twice in the morning. Returned to main dealer and they kept it for a few days. They said it was fixed and just needed software upgrade. Now its happening 6 or 7 times a day usually first thing in the morning and also on acceleration passing someone out. The dealer cant take a look for another week. The dealer is not admitting that whatever happened was as a result of the service. But I find it hard to believe that it started happining the day after a full service. Can anyone help?? It is quiet dangerous loosing power on an overtake and then having to immediately get to the road edge to stop and start again.
