2017 Jeep Cherokee engine problems

“Hello, I am writing to follow up on an issue I reported a month ago regarding an unaddressed recall on my 2017 Jeep Cherokee. The vehicle is currently not drivable due to significant consequential damage to the transmission caused by a failed Power Transfer Unit (PTU). I purchased this vehicle nine months ago at 51,000 miles and have driven it fewer than 5,000 miles since. The PTU failure has led to the following severe mechanical issues: - Stripped Transmission Output Shaft: Due to wear on the differential input splines (associated with NHTSA Recall 20V343 / Manufacturer Recall W47), the transmission's output shaft has been stripped. Consequently, replacing the PTU alone will not resolve the issue, and the transmission requires repair or replacement. - Debris Contamination: Metallic shavings from the damaged PTU gears have entered the interconnected mechanical linkages of the gearbox. - Loss of Power and Park Function: The internal break caused the transmission to disengage from the differential, resulting in a loss of motive power and a complete failure of the PARK function, creating a roll-away hazard. Given that this critical recall was never performed…”

“I was stopped at a red light. When the light turned green, I took my foot off the brake and pressed the accelerator. bI heard a loud cracking/crushing noise coming from underneath the vehicle. When I tried to accelerate, the Jeep would not shift properly into gear. The engine revved, but the vehicle did not accelerate normally / did not move as it should. The Jeep was essentially no longer able to transmit power normally, so I stopped driving it. The important sequence is: red light-green light-released brake-pressed accelerator-loud cracking/crushing noise underneath-Jeep wouldn't properly engage/shift- engine revved- vehicle accelerated normally.”

“The contact owns a 2017 Jeep Cherokee. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power and stalled. There was an abnormal sound coming from the vehicle and the contact pulled over to the side of the road. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, who discovered that the skid plate was cracked, and after further inspection, the contact was informed about the PTU recall and referred the contact to the dealer for assistance. The vehicle was taken to the local dealer for NHTSA Campaign Number: 25V011000 (Power Train). The vehicle had not been diagnosed or repaired. The manufacturer was contacted and opened a case. The approximate failure mileage was 204,000.”

“The contact owns 2017 Jeep Cherokee. The contact stated that while driving at 70 MPH the vehicle lost automotive power, and the transmission shifted into a lower gear. No warning lights were illuminated, however a message appeared on the instrument panel "Service Shifter". The contact veered off onto the side of the road in order to restart the vehicle. The contact continued to drive the vehicle when shortly after the failure reoccurred. The vehicle was taken to a local dealer where it was diagnosed, and the contact was advised that no failure was found. The contact referenced NHTSA Campaign Number: 25V011000 (POWER TRAIN) as probable cause for the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 70,801.”

“The contact owns a 2017 Jeep Cherokee. The contact stated that while driving 57 MPH, the check engine warning light illuminated and the message to “Service Vehicle Immediately” was displayed. The contact stated that the 4WD setting switched from “Auto Mode” to “Snow Mode” independently. The contact pulled over to the right side of the road and remained there for two hours. The vehicle was turned off and restarted and the vehicle, and the vehicle operated as intended. The vehicle was then driven for seven miles before shutting off unexpectedly. The vehicle was repaired under NHTSA Campaign Number: 25V011000 (POWER TRAIN); but the repair failed to fix the vehicle. The contact stated that the failure had occurred two weeks after the recall repair. The manufacturer was not notified of the failure. The failure mileage was 100,000.”

“Back in July of 2025, my vehicle Abruptly Stopped and lost all power on the thruway. Vehicle was towed immediately to local dealership (emerling Jeep in springville ny ), where it then sat for almost 9 months awaiting a safety recall related to the PTU, as was confirmed by dealership. Fast forward to this year, early April 2026, I finally received vehicle back, and was informed a new PTU /software program update had been performed on my 2017 Jeep Cherokee. Upon driving my car off dealership lot, I noticed my inspection sticker had expired, and my vehicle wasn't operating at a normal pace. A constant thud, transmission delay was evident almost immediately. Attempting to finally try and get my vehicle back to its normal condition, I drove to a nearby Mechanic to try and get car inspected. Not even 30min after receiving vehicle back, it started to lose power again. I was luckily able to get to mechanic, and after close inspection of Vehicle, he informed me that my car wasn't safe to drive. The rear differential was now in jeopardy. Mechanic said the constant strain from bad PTU likely damaged my rear differential, and that it needed to get replaced. When I…”
