  1. Just had the tsb done. Seems to have more consistent power. Unfortunately It did not cure the “STALL BUG” as hoped. I stalled literally on the way home from dealer.

  2. Is the stall bug you are experiencing like the one I am? Twice (on two different days) while climbing a mountain pass in Colorado the vehicle shut off, the dash lights came on, and then the engine came back to life like nothing happened. I have not taken it in to the dealer yet.

  3. Locklears told me there is nothing wrong with my jeep its shut off with me once so far and it has done it to my dad and step mom when I have let them use it on Tuesday this week of march 15

  4. it still shuts down while driving this will be the 2 time its been to the dealer for the same prombem WILL MY FAMILY AND I DIE IN THIS POORLY MADE VECHILE
