I'll tell you the safety issue. Taking it to the dealer four times for this exact issue. Yes I was able to make it stop. Unexpected, sudden occurrence. Significant effort, not nominal. Sometimes in much less than ideal conditions (read: crowded parking lot in rain, positioning to park on an incline...)
I wanted it fixed. Dealer ultimately traded me out - '16 for a '16 - special consideration, but no specific allowance for my concern. As in, the next guy could have gotten the same deal. Yes I lost money even as I realize my vehicle isn't an investment. I couldn't stand the risk - especially as I couldn't get a diagnosis.
Now, it's a recognized issue. I'm glad for y'all.
