Chrysler discovered that certain 2018 Pacificas made between November 1, 2017, and March 1, 2018, have steering joints that  may separate, albeit under unusual conditions (e.g. if they are not torqued correctly, and there is a wrongly positioned opening). If the joint separates, the driver can lose control of the minivan.

So far, Chrysler doesn’t know of any related crashes. The free service will be available next month.

The issue affects around 50,000 minivans—47,771 sold in the US, 2,239 in Canada, 226 in Mexico, and just 551 “everywhere else.” The exact part is the right front lower control arm ball joint stud, which can separate from the steering knuckle under exactly the right conditions.  The fix includes both an inspection, with replacement if needed, and replacing the right front lower control arm knuckle pinch bolt with a larger-diameter pinch bolt.

The company discovered the issue when they started to get warranty claims for noises from the joint. After the build date of February 28, warranty claims fell.  Chassis Engineering tested the components in late 2018. There have been five customer complaints and one field report, with no crashes or injuries reported.
