According to Allpar sources, the Jeep Wagoneer was originally scheduled for a 2015-model-year launch. Not only wasn’t it ready then, though, but there was no production capability, with both Ram and Grand Cherokee/Durango plants at their peak.

The next possible date was 2019; but the Ram 1500 program was pushed back a year so Sterling Heights could be converted to make Rams. Warren is set to be converted in the winter of 2018-2019 — pushed back from the original schedule so they can keep making the current Ram 1500s, while Sterling Heights slowly ramps up the next-generation Ram 1500. That should help avoid, or at least minimize, quality issues.

Thus, once Ram 1500 (DS) finishes up at Warren, the plant will shut down for about four months; and then the Wagoneer/Grand Wagoneer (WS) should launch in Fall 2019, as 2020 models — as far as we can tell. Heavy duty Rams will show up next — though they are likely to continue in production in Mexico, as well.
