Actually, I have gone for a couple of weeks or so without experiencing the chugging and then I will have it happen 2 or more times in a single week. It sure is nerve-racking. I was glad to read the post that one person has also experienced it in tow/haul mode (my dealer asked me to run it in tow/haul for a while but after one afternoon of running errands, the birds with that idea).
