Service shifter light comes on and off randomly while driving. Won't allow my vehicle to restart after shutting off without getting a jump to start it. Had the shifter replaced on 3/31/22 at 64,000 miles and now again it's happening at 89,000 miles on 9/29/2023.

Several months ago, my dashboard displayed a service four-wheel-drive message. I took it to a mechanic. They diagnosed to have the code C14A7-97 CPU motor component system operation obscured or blocked. Further research was conducted and there are several bulletins out for this year and model regarding differential input splines wearing out due to a manufacturer issue creating a major safe issues. In addition on several occasions the warning light for my parking brake has come on, according to an article I read this is a symptom and safety issue related to the transfer case flaw. I speculate a parking brake failure could potentially cause a roll away. There is no recall for my specific VIN for this issue although it-??s evident that this is one of the Jeep Cherokee-??s that was effected. I fear that if this causes my vehicle to lose power while driving could lead to a serious accident.

September 6, 2023 my 2017 Jeep cherokee started making noises while driving and the service 4wd light came on. I called Quirk Jeep service and I was told to not drive it and have it towed to the shop. The problem was diagnosed as a PTU failure. I was not off road but on a local paved road when it failed. As of today 9/13/23 I was told there were no PTUs available anywhere and my car was not covered by recall W47 (20V343 NHTSA).

I did have an incident in July of 2022, my car would not get out of park. I was in a drive through and put my car in park. When I went to put my car in drive. The vehicle completely shut off and began to roll backwards. The next set of issues, I first noticed the issues in the beginning of 2023. The service 4wd light is on and the parking brake will not engage. The 4wd itself works just fine, each terrain mode will engage. So Ilderton Dodge Chrysler Jeep Ram (High Point, NC), looked at my vehicle and said the PTU was bad and needs to be replaced. This passed weekend, I was driving entering a highway via acceleration lane and my car had trouble switching speed limits. Which leads me to believe the necessary power was not able to perform. This is detrimental to the safety of myself and others. Should my car's brakes fail or car lose power; it could seriously injure myself, innocent people in the vicinity of my car, or mechanics working on my car, etc. I work at a Pediatric office and would hate for the brakes to fail at work. Chrysler has already recalled 96,000 Jeep Cherokees for the exact same issue. Due to this, the PTU is back ordered and cannot be located anywhere in the US.

I brought car in for oil change and was told the R front axle was leaking. Brought it to dealer for repair and told Both that both front and rear axles needed to be replaced along with PTU. Was informed that the that was ordered was cancelled b/c 800 people across the country were looking for the same part. There were no safety warnings. I was told very unsafe to drive b/c front axle came out of PTU.

Service shifter message has been appearing and at times, all lights on PRND lighting up. The vehicle transmission may still engage or may not. Recent occurrence on 07/13/2013, vehicle took 20 minutes before transmission engaged. Fortunately, I was parked at work, going home. If this occurred on the road, has potential of wreck happening. Jeep dealership leaning towards voltage error, cleaned battery terminals, test drove, could not replicate error. Did not drive until 07/17/2023, service shifter message came back without all PRND lights coming on.

SHIFTER SERVICE light appears chronically while driving and locks the digital speedometer, all lights on console go red until car is parked and restarted. No one can tell me what this means, or how to fix it... not even the dealer. Totally scary as I travel alone a great deal of the time, and today is just the latest occurrence of this over the last 18 months.

"Service Shifter" light came on, and all my shifter's lights are red. Looking across the internet, this is a widespread issue. Thankfully this didn't cause an accident, but it sounds like some users report not being able to shift into park. Will be taking to the dealership soon (its too late in the day to drop it off now).

Upon starting the vehicle, the service shifter message came on the dashboard screen and all the lights on the shifter illuminated red. If I drive with it on, it stays on. When I turn off the Jeep and turn it back on, the message and lights go off. However, this message has appeared about once a month for the last few months. It is unknown if my safety has been at risk. I've called two different dealers and got widely different answers about what the problem could be, as well as very different cost estimates to fix it. But, no one really knows what the fix is. I've investigated this problem online and have found 100s if not 1000s of complaints about the same problem with no clear solution. Why is there no recall for this yet. It's been going on for years.
