How's it going folks. So as the title suggests, my 17 Bolt has an occasional grinding noise when I put it in park. Typically on an incline. I've seen one other thread about this issue, but I made this new one because the other thread blamed it on the parking mechanism. I thought the same thing, because I noticed it when putting it in park, because sometimes the brake engages automatically. I have narrowed it down to the point where I know it's the parking brake, because I can replicate it using only the brake and not the park button. The dealer is stumped. They recalibrated it, and said they inspected it for damage and found nothing, but it grinded again this morning. It sounds just like an automatic transmission does when you force it into park while the car is still moving, or if you try to force a manual into gear without pushing in the clutch. Has anyone else experienced this? This is my first EV and also first car with an EPB, so what could the sound actually be coming from? I'm not happy with it... I've got half a mind to get GM to buy the car back from me. A brand new car shouldn't be making such noises.
