Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Purchased the vehicle with safety tech package which includes aeb (auto emergency braking) and vehicle did not stop even when I applied full brakes to prevent a collision. The main reason I purchased this vehicle was for this safety feature.”
NHTSA complaint #11099431, filed 2018-06, 1,800 miles“Rear hatch indicator suddenly comes on while driving and rear hatch opens on own. Even after hard slamming shut hatch is not latching all the time and randomly loosening and opening on its own. Loud rattle is also coming from rear of vehicle. This is a newly purchased automobile.”
NHTSA complaint #11129850, filed 2018-09, 250 miles“Both the right passenger door handle and rear drives side door handle have come off, in both cases a passenger was opening the door to enter the vehicle when the door handle failed and came off. The last incident back door occurred 9/7”

This design would be completely unacceptable for the trunk of a sedan and it should also be unacceptable for a hatchback or liftgate. A relatively inexpensive fix would be to install a simple metal lever in the door through the slot provided for inserting the key. …”

I called the dealership where I was informed they did not have any mechanics available to look at it until August. No one to work on Hybrid. I then took it to a mechanic shop, And I was informed to take it to the dealer. I could not drive the vehicle.
