My SVC4wheel is unavailable temporarily service needed is on been on since I got jeep recently I was thrown into a ditch and wasn't able to control the jeep due to no 4 wheel drive but my stability control is tied to that. And I believe it is part of the recent ptu recall jeep just had from 2017-2019 jeep Cherokee. I have exact same issue. My jeep acts like it wants to always stall which is part of the recent recall lose of power to the power transfer unit b could become damage band stall . My jeep has exactly same issues as that recall and I was out in a ditch due to lack of power to put it in 4 wheel drive.
