The parts could break without warning.
Fiat Chrysler Automobiles U.S. will recall a total of 1,180 examples of the 2016 Ram 1500 and 2016 Jeep Cherokee across three safety campaigns to replace their front half-shafts, which could fracture. The 99 affected Rams have build dates from February 19, 2016, to March 3, 2016. There are also 52 Cherokees in need of half-shafts on the left side, and they have production dates from September 30, 2015, to October 2, 2015. Separately, there are 1,029 Cherokees that require a right half-shaft, and they have manufacturing dates from October 3, 2015, to March 22, 2016.
On the Ram 1500s, a manufacturing error at the supplier caused the both front half-shafts not to receive the proper heat-treating. It’s possible these parts could break while driving, which could damage the vehicle and leave debris on the road. However, FCA U.S. has no reports of the parts failing, and there are no records of any accidents or injuries.
For the Cherokees, the supplier exposed the half-shafts to too much heat during manufacturing, which could make them more prone to breaking. Again, FCA U.S. has no reports of the parts failing on these crossovers or cases of accidents or injuries from this issue. However, the company’s internal testing shows these half-shafts could stop working prematurely. During the evaluations, they last the equivalent of “approximately 108,000 customer miles while the test target is 150,000 miles,” according to the automaker’s documents to the National Highway Traffic Safety Administration.
Dealers will replace the half-shafts with improved parts in these three recalls. FCA U.S. has not said when these repairs would begin.
