I suspect there is a service bulletin out there on the Fiat Chrysler Autos repair computer system. The reason that I thought this that I checked my favorite sites while working on this question and it came back that there were repeated errors with the Electronic Stability Program/Brake Assist System.
This system comes on whenever you need help with uneven traction surfaces. The engine and brake system move the power between the driving wheels to help keep things as steady as possible. There are also times when you may be accelerating and the engine is working hard when you need an assist with the stability as well.
Suffice to say that this system is also integrated with the ABS so that it comes on and tries to help keep everything stable no matter what the conditions.
Now, as to the reason I suspect there might be a problem and a quick service bulletin, it is that I have seen several reports from Jeep/Dodge owners who reported that the system flashed the ESP/BAS light on and off for a time. The dealership was advised to enter in some new software and reflash them to correct the error.
If the error keeps happening it may be that a dynamic sensor isn’t working correctly. If it is you will be happy to note that it is covered by warranty. However, you may lose your car for a day or more.
