O2 Sensor Issue I Think...
Yay, first post here for me!
Just had a similar issue on my '14 Base Sport Coupe. Took it to the dealer and they said that there was an O2 sensor part number change around the time when my car was built (early Jan, 2014) and my car had three correct O2 sensors installed and one wrong sensor installed from the factory. (Old part number...) My car tripped the P2099 code which is the same as yours but the other bank. I have 2600 miles on it. Bone stock.
Wonder if you have the same problem I do? The new part is backordered at the moment.
Good luck.
