My truck Tuesday March 16th had me update software as soon as I got to work, after it was done I got out of my truck and it would not lock with push button or fob. When I got into my truck to go home 10hrs later it made a bunch of clicking noises and after a minute it showed update complete on screen then started. The very next day I drove back to work which is 22 miles. When I took my truck to lunch three blocks away I had esc service light and service parking brake accompanied by check engine light. I called local dealership to get it looked at and they said Friday was as early as I could get it in. I left work early at 1:30 and tried to drive it and it was squalene like a bad power steering pump and shaking as I drove. I went ahead and took it the dealer.
