Kramer, welcome aboard!!! IRV2 is the greatest source of RV info you'll find on the web.
There was a recall on the Actia IP regarding brake ABS warning light, but I don't know if it affects your model year.
I suggest that you get your VIN # and go to the Workhorse Website Link
. Click on "My Workhorse" and create your account. Once they have your VIN, you can see all the open & closed recall campaigns for your chassis. You can also read the details of the recalls.
In 4 years I've had my IP burp many times (6-10) and it always seems to recover ok. I've checked the connectors in the back of the IP and the ground wires to the frame, but never discovered anything.
Good luck and many happy miles,
Bill (Dune'r) & Helen
