Two problems related to automatic transmission control module have been reported for the 2016 Jeep Wrangler. The most recently reported issues are listed below.
My vehicle has been in the dealership approx. Four times, because the service engine light comes on, followed by the traction control light. They said that the cable connection gets loose and they soldered it. This started about 20000 miles and is now at 57778 miles. This last time on 4-24-2019 they said that it has stored codes for the cam sensors on both banks and torque request denied signal and torque management signal performance. P2638, c121c, p0344, p0369. They said that it has pcm update and that they performed the pcm update again and cleared codes to see if they would come back. Vehicle driven 30 miles and and one large bump in the road and the lights turned on again. This happens while going down dirt roads. They also told me the first time that it was taken in that the cable is to short and causes stress and stretches, causing it to come loose. This time they said if the lights came back on that they would have to have the vehicle back to do more extensive tests and possible replace the sensors at my expense. This seems to be a reoccurring problem that always comes back. They also stated that this is a problem on all Wranglers. This seems to be a manufactures defect and needs to recalled and fixed.
While driving on city streets the manual transmission's shift lever became loose making it difficult to shift into any gear. The lever would rotate 360 degrees around its center and eventually come completely off of its mount. When rotated, the offset in the shift lever being at a new angle would lead to shifting being obstructed by the driver or passenger's legs and seats. After coming off of its mount while stationary gear selection became impossible without repair. Dealer would eventually complete a repair under warranty. Items noted on the service order: lever: 52060064ag, screw: 6506668aa, pcm update flashed.
