They claim it’s all up to date. I specifically asked about the TSB’s and my SA said they were current??
Hmmm... Might have to see if Jeepcares can do something for you if your dealer isn't doing a good job.

I escape form, but with my short driving distance, come right back. So no point to clear form for me. Im always in form from nov to april, but still check my annual average fuel. So form is not that bad when you calculate your entire years average.

Having had never ending FORM I did a lot of reading around:

a) you should clear form else you will lose your oil - it's there as the fuel injection leaves petrol in the oil - too much and the oil is useless and has to be changed. So you need to get the oil > 190ish for 20mins to a couple hours to evaporate it off, which is why it tends to be harder to clear in cold weather & takes longer to clear the more you leave it.
b) Found easiest if you have low mileage is to drive in e-save, use manual and slightly over rev or take a few steep hills to get it hot fast and then driving normally in auto for a while - also getting it hot then leave it running in parking works great if you can do that. Apparently it won't clear FORM while in manual so you need to change back to auto once heat is up.

I found the facebook group had some responses by jeep & others about this that really helped my understanding of it.
I have low mileage journeys & personally have found the get it hot/leave running in park by far the best to clear it. For me it seemed that if I left drivers door open in my garage while running it didn't auto turn off.

a recent 285 mile round trip to the mountains skiing did the trick; out of FORM and Electric even latches the next morning with temps in the 25-20C range. (knocks onwood)
