Clutch Pedal/linkage problems of the 2016 Subaru Impreza Wrx

I started having problems with the clutch/transmission in my 2016 wrx at 580 miles. I was exiting a highway and pulled the transmission out of 6th. As I was about to shift into 3rd to go through the intersection I was unable to shift into any gear (stuck in neutral) with the clutch pedal fully depressed. I had to pull over turn the car off and restart it before I could get the transmission into gear. The problem occurred again at approximately 3500 miles. This time I was driving down the highway shifting from 5th into 6th. I pressed the clutch pulled the transmission out of 5th and could not get it into 6th or any gear. I pulled onto the shoulder and still could not get the car into any gear. I turned the car off and went back to restart, with the transmission in neutral, when I let up off the clutch the car stalled. I put the transmission into 1st, pressed the clutch and started the car. When the car started this time it lunged forward. I was able to get back on the highway. I immediately took the car to the local Subaru dealer. They were unable to duplicate the problem and said there was nothing else the can do until the are able to duplicate the problem. Since the second occurrence I started noticing a strong burnt smell at low speed (shifting 1st to 2nd) and at cruising highway speeds in 6th gear. About 1000 miles later it happened again this time not only could I not shift into any gear I could not get the clutch pedal to come up all the way, this occurred at 35mph. I had to press the clutch several times in order to get it to come up fully, then I was able to get the vehicle into gear. The burning smell was present when this happened. I took the vehicle into the dealership I purchased the car from. They have been unable to duplicate the problem. They also claim they can't work on the car until they can duplicate the issue.
