2017 Chrysler 300 won't go forward or backward

shifter knob gear indicator will start blinking and car will not go forward or backward. This is the second time. I was told it was a computer programming issue the first time. had to have car towed to the same dealer who worked nn computer the first time,
Has anyone else experienced this problem? Car has about 34000 miles on it now.

You may wish to take it to another Chrysler dealer while it’s still under warranty.
