NHTSA Complaint #11479692 — 2016 JEEP CHEROKEE

The SVC 4WD (service 4WD drive ) light came on in my 2016 Jeep Cherokee. The Jeep dealership performed diagnosis and the drivetrain control module (DTCM) stored C14A7-97-PUT motor and the component or system operation is obstructed or blocked. They attempted to update the software of the DTCM and it is up to date. The condition persists and their further testing indicates that the internal power transfer unit (PTU) has failed and the vehicle is stuck in 4WD. The vehicle has not been inspected by anyone other than the local jeep dealership, which was on 8/12/2022. The warning message began the week of August 1st and I scheduled the first available service appointment. After some initial research, Jeep had a recall of the PTU for my model year back in 2020. For 2014-2017 Jeep Cherokees where the PTU has not been previously replaced, the auto maker’s recall number is W47 and the National Highway Traffic Safety Administration (NHTSA)’s recall campaign number is 20V343. However, when I checked my VIN number, it stated that I had 0 outstanding recalls against it. It is my understanding that if the power transfer unit (PTU) fails to engage with the transmission, the Cherokee could lose all power while being driven which could result in a crash or injuries.
