Transmission Fluid Leaking problems of the 2012 Honda FIT

While driving home at the end of the day, the car started to lurch around 20 mph while driving straight in a parking lot and on city streets. This had never happened before. The lurching continued for the next 3 miles until I got home. Couldn't take it to the Honda dealer because service dept was closed. The next day, the mil indicator came on when I started the car. However, there was no lurching around 20 mph while driving on city streets to the Honda dealer. Honda found two codes: (1) p0456 evap system small leak and (2) p0847 transmission fluid pressure switch b (3rd clutch) (short or stuck on). Honda troubleshooted and stated in their paperwork "found evap gas cap has not have the updated gas cap. Also found the transmission 3rd pressure switch is stuck on. Recommend to replace the gas cap and the transmission 3rd pressure switch. " I asked if work was covered under any warranty and was told no. Quoted repair cost of $160 (for item 1) and $650 (for item 2). Didn't expect these types of problems with a Honda car.
