NHTSA Complaint #11694242 — 2022 VOLVO XC60

While driving on crowded I40 near Statesville NC, the engine started to stutter and moments later quit entirely. Fortunately we were able to move to the shoulder with only a few seconds to spare. This was very dangerous as we had to move through the right lane in front of speeding semi trucks. The only warning light received was that there was an engine problem, that the car would go into “safe” mode. This was mere seconds before entirely disabling the engine. Had we come to a halt on the highway there would have been a serious accident and injury to ourselves and most likely others. We contacted Volvo, a tow was dispatched and the car was winched on to a flat bed trailer and we were transported to a dealer in Hickory. Later it was confirmed that the Integrated Starter General (ISG) had failed and that power had been interrupted to the hybrid battery. There is a serious problem here and I suspect may impact other “mild hybrid” systems that install integrated alternator/starter motor systems between the engine and transmission.
