My 2017 Malibu Hybrid with 70k miles began to chirp about 2 weeks ago a as the engine cuts off or back on. Whether moving or stopped. It is like a rubber belt on a pulley (perhaps some sort of clutch). Well it has rapidly turned from a chirp to a squeal, now lasting 3 to 8 or 9 seconds with every transition. I'm afraid if something fails completely I'll be on the side of the road.
