The original problem was that the car wouldn't start after auto-stopped while driving. Dealership replaced starter and 350A fuse for $600. Car did it again the day after got it out of shop. THEN replaced flex plate that had missing teeth for $4,000. Then had to take it in because they forgot to add fluids before giving it back to me after they had it a month. NOW it doesn't shift right ever since I got it back. The car rumbles and vibrates when it shifts gears. Now they say I need to spend $7000 to replace the transmission.

So mad. Loved the car until now. This happens at 40K miles, really?? Began to notice a bad shudder at I accelerate from a stop and continues until you get to cruise speed. Per dealer, Tech Bulletin PIP5608F, too much grease build up, overfilled at factory and the fluid is turning into grease from hot cold cycles, and if I am to replace fluid and drive it 200 miles, and if it still does it, I need a new transmission. So distrusting right now, this is probably a Band-Aid until I am out of warranty, make it last another 40K and then screwed - ugh!!!

Update from Apr 24, 2024: So far seems to have fixed the issue by changing the fluid. However, they would not cover it under warranty and charged me $300+ for the work.
