The recall doesn’t cover many 2018 Jeep Wranglers, but it’s still a doozy, because the company is still trying to develop a remedy.

Recall U27 covers just over 100 Wranglers sold in the US, presumably as well as a scattering sold elsewhere; and of these, only around half are probably an issue, according to the company.  The problem is that vehicles built at Toledo South on October 15-16, 2017, may have used parts that don’t have sufficient corrosion protection.

Over time, and with the abuse Jeeps are supposed to get, the driver’s-side rear structural under-body ladder rail in these vehicles can lose strength. That can result in a loose left-rear seat mount, or a weakened rear floor pan, which could result in injuries during a crash.

FCA will provide full information to dealerships on June 1, 2018, according to the current schedule. The company started an investigation on October 24, 2017, when someone noticed that the parts looked different from other production parts. The company’s response team met with various engineering teams about the issue, to determine the scope and effects; so far, they have not released an approved repair.

So far, there have been no reports of any incidents at all related to the issue. Owners are unlikely to see any issues this early. The affected part is the underbody floor pan reinforcement, part 55397055AC; it was made by a supplier in Canada. The problem only affects the older design, the Wrangler JK, not the newer JL.

Stock photos do not show 2018 Wranglers; the appearance is similar.
