I searched around because i know there have been some drivetrain noise reports. All of the posts i found were describing the acceleration noise - however i seem to recall people having issues, and ultimately needing drivetrain components replaced. I couldn't find these threads. I had an issue that cause my car to get trailered to a service center. Official cause listed as "connectors to the high voltage system were faulting" - and they were replaced. Since i was on a mini road trip and getting some error messages at the same time, i began paying extra attention to the vehicle. At speeds above ~60mph when i let off the accelerator i began to hear a noise - a hum/whir or whine type of noise. I don't believe this was there before. At slower speeds i hear nothing. It was doing this on different roads - i.e. its not a road surface type of issue. Any experience shared, or assistance finding the other threads would be welcomed. Its tough for me to get the vehicle to a service center, so If I'm on the verge of another issue - id rather pursue it now!
