“November 26th my car went into LOMP mode. But then restored itself. December 3rd my car went into LOMP mode again and had not recovered along with a slew of ALARMS. I have been using uber and rental cars since this issue. Highly likely this is a fuel pump issue but unable to determine as the authorized shop is 2hours away and the car will not make it there. I need a remedy I have been out of a car for months now and the recall has no remedy!”

He applied his brakes to avoid hitting me and started to jackknife, but regained control and continued. The truck missed by inches. At this point I had NO remaining power and was essentially coasting until I managed to cross the remaining two lanes of traffic to the shoulder emergency lane. …”

“2018 Stelvio Quad 7/2025 Taking off from a red light with multiple cars behind and beside me, my car lost power throwing multiple warning lights, swapped itself from D to N driving mode and had to be limped off the road and restarted. It would not swap modes from N . Displayed check engine light. Contacted my service manager, completed 10 restarts, issues cleared. Car would drive in all modes without issue. 2 weeks later having had no issues and assuming bad fuel, at the same light I was nearly rear ended because it did the same thing as before. …”
