Hi

The Rubicon has a problem - the check engine light and ESC light comes on at a bump and engine goes into limp mode. At first it was only in high range but then it occured in low range, then once in 2wd towing - it needs to have the engine turned off to reset limp mode.
.
It has had the the computer reset and some upgrades applied at a dealer whilst we where away and they said it was OK to drive it with those codes until we got home

After the reset it started occuring at every little bump in 4wd (high and low) and then in 2wd a few times - once trailer was connected it was constantly going off even in 2wd.

Going to the dealer we bought it from on Thursday but any ideas?

I think a sensor might be gone on one of the front wheels - the hot weather seems to make it worse as since we have been home have only had it happened twice on Saturday afternoon and now check engine light has gone off.
