Service shifter message appeared at 62,000 miles upon starting engine and shifting into any gear or turning on cruise control. Will go away after approx. 5 seconds but occurs every time the car operates. Is not showing any error codes and appears to be a recurring issue for many owners and related to wiring harness and shifter.

I have been aware that my model of Jeep has a history of problems and legal suits concerning the gear shift. My Jeep is an automatic transmission as decoded by the VIN. The shift selector has all of a sudden been saying service shifter. And as the days have gone by the problem is getting worse. Now if I put the vehicle in park it indicates that it is in park on the dash, when I let go of the brake without touching anything it then goes into neutral on its own. This has caused multiple times now where I have stepped out of the car or turned it all the way off while it indicated it was in park but in fact it had switched itself to neutral causing the car to roll. Luckily it has not cause any harm to persons or property. This is a serious concern/defect in the way it is operating and it is putting the public safety in jeopardy. I have search and it says there are no active recalls for this problem or in fact any for my car. I feel that this is a serious electronic malfunction and should not be a responsibility of mine to fix. In the days of manual (lever action) gear shifters this would not be possible. This seems to be an electronic issue as the computer is somehow changing the gear from park to neutral on its own. In a conventional gear selector you would have to physically go through reverse to get to neutral from park. With electronics these days there is no human error of accidentally moving down to neutral. It is doing this all on its own and if you are not careful or paying attention it could cause the car to roll down a heel out of control with nobody inside to stop it. Or even worse while my 8 month old daughter is inside and I get out of the car to go to the back to get her and it start rolling.... please assist and look into this very important and concerning issue. Has been occurring over the past month randomly.

2015 Grand Cherokee altitude- 3.6L. Just hit 95000 miles and suddenly car continues to up shift to 8th gear even at lower speeds. When accelerator is depressed, car will downshift but with no acceleration depressed, car will move all the way to 8th. Downhill, trans won't shift beyond 3rd gear likely to engine braking only. This is my 5th Jeep and my 4th time dealing with this issue across my Jeep.

Service shifter light comes on while the vehicle is in motion on the highway. Has occurred multiple times and has been checked out by Jeep service centers twice. They can not find the problem. During one drive, the service shifter light came on but also, the complete dashboard, including speedometer and engine indicators all when black and engine started to slow. Within about 20 sec, it would recover. This occurred several times over a one hour drive.

My car goes from drive, to park, to neutral or reverse with little to no touch of the gear shifter. This is a huge safety issue, as recently assuming I was still in drive mode, noted that the gear had actually shifted to neutral. Had it shifted to reverse instead, my children and I could have been badly hurt, likely found to be at fault, consequently also facing financial anguish. Also, the gear shifts while in motion, which is even additionally dangerous being that I live in a city where the highway is my primary method of traveling.

Arrived home 10:15pm dry roads and weather. Backing Jeep into driveway and went to full throttle back to hit the garage structure and door. Shifted two drive to move out into the driveway and went to full throttle forward, across the street, through the swale into a vacant lot and hit the avista power transformer box knocking its off the base and pulling the 7,000 volt power cables out. Jeep then stopped and I backed it back into the driveway and stopped. Avista crew arrived and safed the transformer. Resulting damage was $3,007 to house and garage door, $16,275 damage to front/back/undercarriage on Jeep and about $4,880 to replace the avista transformer. Car rental now 60 days at $42 per day.

At approximately 60,000 miles the vehicle had just been serviced and new tires were installed. We left the next morning for a vacation. About 100 miles down the limited access highway and traveling at 65 to 70 miles per hour the dash and information touch screen began flashing and a chime began repeating. The windshield wipers began operating at high speed. (it was clear, calm and about 65˚ F. different messages began flashing: One said to stop and place the vehicle in park, another said to keep driving and not turn the engine off. When able to exit the highway the Jeep would only allow selection of drive or neutral. It would not allow reverse, which made it difficult to turn around. The vehicle did make it back 100 miles to the dealership but would not shift and lights flashed and chimes dinged the entire way. The dealer informed me that an electronic system associated with the transmission has failed and will cost approximately $1,000 to replace.

I have a 2015 Jeep Grand Cherokee with 49,000 miles. In a three day period the transmissions started to have problems shifting a total of five times. It would violently start to shudder while in motion at highway speeds and nearly caused a terrible accident. I had to bring vehicle to complete stop on highway and restart. I took the vehicle to planet Jeep in flagstaff, AZ for check as it is still under warranty. I was told that they cannot re create the issue and if they have to remove transmission pan to inspect I will be liable for cost of repair. I called fca customer service two times and they do not return my calls. I feel this is a dangerous problem that has potential for death or serious bodily injury and am not sure who to turn to at this point.

I have the 2015 Jeep Grand Cherokee ecodiesel that received the emissions update required by the epa diesel settlement which Chrysler fca. I noticed substantial lag problems the instant I pulled out onto the open road after the update from Bonneville Jeep in manchester nh. The vehicle is dead off the line and there is a 2-3 second turbo lag at all speeds. You end up giving more throttle than you want because the response is so delayed, and then you get a massive surge of full throttle which can be unsettling and make the vehicle unstable in a turn. Very scary to ride when my wife or kids are driving who aren't used to the issue. Pulling out into busy intersections, even with a warmed up engine is a dangerous, white knuckle experience as the vehicle crawls like a tortoise into the middle of intersections before the power finally comes after 2-3 seconds.. the service department is sympathetic but says corporate has turned its back on their reports of complaints. I believe the so-called settlement documents should be voided by a new class action suit - the terms of the settlement and their ad materials and even their customer service voice response recording say that there will be no loss of power, no impact on drivability or smoothness, and no change in mileage. All of these are untrue. They have destroyed the drivability and joy of owning these vehicles. More than that - they have made these vehicles extremely dangerous to drive. We've been scammed. Chrysler should be forced to buy back these vehicles. I may be trading mine in.. my 3rd and final Jeep.

We had our 2015 Jeep Grand Cherokee worked on to repair the issues per NHTSA recall # 16V-240. Recently, the Jeep alerted me as I was driving at a speed of approx. 35 mph that the "autopark has been disabled." My dealer is unable to figure out why this recall/software update has failed and rendered the "additional mechanism to mitigate the effect of operator error in failing to shift the monostable gear selector into park prior to exiting the vehicle" currently useless.

Service shifter warning

- Columbia, IL, USA

I had the approved emissions modification completed on my ecodiesel Grand Cherokee. Since these was completed there is a very noticeable lag when pressing on the gas. When trying to pull out into an intersection the lag is so bad (1-3 seconds) and you feel as if you are unable to move. This is going to cause some sort of accident as it is a definite safety hazard

- Palmyra, VA, USA

For vehicle with VIN number [xxx], after a VO8 flash of the ECU due to emissions recall settlement the car has serious "lag" in acceleration from the stop position. This is a safety hazard as the lag creates a collision risk from on-coming traffic. Currently the manufacturer does not have a solution for the software update that has caused the safety hazard.

Shifter service warning light. Requires shifter module replacement

- Shelton, FL, USA

While traveling approximately 70 miles per hour (on a highway), on two occasions working 24 hours, the vehicle shifted from drive into neutral with no manipulation of the shifter. There was no warning of the impending loss of mechanical power to the drive wheels, and I was forced to coast to the shoulder of the road. No other systems (brakes or power steering as well as other electrical systems appeared to be affected. Once on the shoulder and completely stopped, I attempted to shift the vehicle back into drive, but was prompted 'shift not allowed - vehicle speed too high' despite the fact that the speedometer read 0 mph. Next, I pushed the start/stop button and the vehicle did not power down, but did allow me to shift into drive. The error has not replicated more than once per start up sequence (if it happens once while driving, pull over and restart, the error seems to not recur for the duration the vehicle is in motion for the rest of the trip). Oil pressure and temperature as well as transmission temperature were reported as within normal operating ranges. I checked the vehicles oil level which was within the 'safe' zone on the dipstick. The vehicle had over 1/2 a tank of gas. This issue is new to the unit, with over 16 months of operating the vehicle it has only occurred within the past 24 hours. The issue is not preceded by any notification, and no mil's were activated either before or after the failure to shift. It is worth noting the key fob is low on battery, but the issue occurs solely in motion. I will be visiting the dealer prior for troubleshooting prior to operating the vehicle again.

Since doing the eco diesel update Jeep has a serious lag / stall when accelerating and when going around 20 miles per hour when accelerating. Numerous times when crossing out into traffic the vehicle has a lag/ power delay almost causing an accident. This was not an issue until the eco diesel update was done. Its currently at the dealership, per the service manager they are aware of the issue and have had numerous complaints with the Jeep and trucks due to the eco diesel update, but they have no resolution.
