In the first incident, the engine stalled. Next incident, warning lights on the dash appeared (engine light, traction light, and throttle control) and when pressing on the gas peddle, the car would not respond (would not increase speed). I had to put on flashers to a warn car behind me. Very scary. Bringing in for service ASAP.

Shifter alarm and need to stop the car to reset. Terrible on the highway engine will shut down. Temperature overheating stopped car working.

The Service Shifter light came on and keeps coming on sporadically. I was dismayed to learn that there are numerous complaints regarding the Service Shifter light on the 2017 Jeep Cherokee. Has this ever been formally addressed.

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.

The car sometimes jumps, propels forward, possibly transmission related issue, and just happens randomly.

Took it to mechanic was told it was 3quarts low in oil but the oil light doesn-??t come on or anything and I-??ve only had the car 3 months so they would have checked oil since they do a multi point inspection

W84 Powertrain Software- July 30 2022 Jerry Seiner Casa Grande Dealership technicians inspected and reprogram the PCM and TCM software and closed the recall but 2 months later all the lights on my dashboard came on check engine light service shifter park brake etc. I went back to the dealership and the advisor told me to go to the dealership where I bought it from. I ended up going to Larry Miller Chrysler Jeep Avondale in Arizona. The vehicle was braking on its own while driving high speeds on the highway and while driving I almost crashed. My vehicle was in and out of the dealership many times and the technicians didnt seem to know what was wrong with the vehicle. Almost 6 months after the initial problem it seems its fixed. 01/13/2023 was the last time I had to return because the dashboard lights were turning on after driving the vehicle an estimate of 100 miles.

Leaking a lot of oil to the point I had to refill every week.

When driving my jeep the dashboard will randomly give me a warning to service my shifter and all of the lights on shifter will go red. I have to turn my jeep off and back on for the lights to go back to normal. I have had to replace the power transfer unit due to the 4 wheel drive not working anymore. I took my car into the dealership to the PCM W84 Recall and two weeks later my transmission fluid exploded and the engine was smoking. Had to replace the heat ignition coil and the inlet hose. Paid $2,000 to repair and a week later my check engine light came on and now my car is overheating. Took it to the dealer and they added coolant and said it was an air bubble in the coolant. A couple of days later the issue happened again, took it in two more times and they filled the coolant, but now saying that the cylinder head gasket needs to be replaced which is another $1,700.

While driving the vehicle suddenly and unexpectedly stops running without any warning. Engine stops. Car just coasts. PRNDL indicator (D for drive) on instrument cluster flashes instead of a constant D. Then some sort of messages comes up similar to "shift to neutral to start engine". Car will not restart. Car coasts to stop without power and no power steering. Then I need to turn ignition off. I will then cycle locks (locked then unlocked). Then turn on ignition. From here the car attempts to start but it is not an immediate start up like normal. The gauge needles (speedometer and tachometer) both go all the way to the right while the car attempts to restart but this startup takes about 10+ seconds of attempted cranking to finally restart. This is a long clicking sound before restart. This has happened 3-4 times now in the 30 days. Most recently on a main road where I had to coast without power and power steering to the shoulder. I have not yet been to the dealer. Car is out of warranty.

When accelerating the vehicle has a hard shift every now and then that-??s very noticeable. Seems to be slipping or having trouble shifting occasionally when trying to get up to speed.

- Carlton, GA, USA

Vehicle turns on but will not start. Changed battery and spark plugs

- El Paso, TX, USA

UNKNOWN. When driving my Jeep there will be times where I go to accelerate and my transmission will jump. Also while I-??m driving all of my gears on my shifter will turn red and a message will pop up saying service shifter. It-??s been happening for a few years but the last time it happened was today 7/22/2022.

On numerous occasions the car engine just shuts off or loses power. This happens consistently. The car has been taken to the dealership where it was purchased and was told "could not duplicate problem". This just happened again yesterday on a main street posted at 45 mph, where engine just shut off. Making left turns has become a gamble as power response is not there. This is a dangerous situation.

The incident happened in a parking lot. Backing out of the parking space, there was a delivery truck parked right behind me. Backing out of my parking space, I hit the bumper of the truck (no damage to the truck). As I pulled back into my parking space the vehicle accelerated very rapidly in a distance of approx. 25 feet; the acceleration seemed "Hell cat" like. Slamming my foot on the brake did not help. The vehicle then hit a brick retaining wall deploying multiple air bags and causing enough vehicle damage that the insurance company declared it totaled. It is amazing that the vehicle hit the brick wall with enough intensity to deploy the air bags and cause considerable front end damage after traveling such a short distance (approx 25 ft). The vehicle is in the insurance company's possession. As such, I do not have access to the vehicle. Had the brick wall not been there, the vehicle could have hit other vehicles or pedestrians and I was lucky to only have minor bruises and abrasions. There was no warning what so ever that this was about to happen.

The 'service shifter' code keeps showing up. The car shifts and drives fine when it happens but it concerns me because I've read where a few people have had the car accelerate by themselves when this happens.

- Stone Mountain, GA, USA

The engine consumes a large amount of oil. I regularly have to add 1qt/ 800-100 miles. The engine will just stall if the oil level gets too low without any warning. In Alaska this poses an extreme hazard, especially in the winter.

- Chugiak, AK, USA

The car will shut off unexpectedly while driving. This is extremely dangerous. This is the 6th time in the last 3 years that this has happened.
