2015 JEEP GRAND CHEROKEE Complaints

January 2, 2025 - the front passenger seat belt failed to retract. Since we always use the seatbelts when in our vehicle, we have not had anyone sit in that seat since. There were no warning lights, messages or hint of a problem prior to this failure. January 30, 2025 took the vehicle to the local Jeep dealer to have the problem looked at. Per the service order, seat belt was inspected using X90 instructions and it failed. Replacement part ( 1VL06DX9AG) was ordered and I was told it would be 2-4 weeks before the part would be available. February thru early May I would visit the local Jeep dealer, as well as other Jeep dealers I may drive by, to see if the part was available and I was told it was backordered and the waiting list for it was growing. May 28, 2025 - Jeep dealer service rep called me to say that it was still back ordered with no idea on when part would be coming in. Until repaired I remain unable to use the front passenger seat.

While driving downtown Atlanta, Ga I heard a loud noise and then a hit in the back of my head. I was startled at first not knowing what had happened. I first thought maybe I way hit by another vehicle, or someone may have thrown something from the overpass. I got off the interstate and found the head rest had blown open. I have since learned that possibly the car maker is aware of the problem, I don't know if the car maker is fixing the problem. I see where this could have negative results to owners that already have neck and back problems, another big concern is having an accident.

On the highway my 2015 Jeep Grand Cherokee Diesel briefly stalled and the check engine light came on. I then lost all power and could only maintain a speed of 45MPH in a 70MPH speed limit highway. I turned on my flashers and could not get off the road due to construction and Jersey barriers for several miles. When I had the opportunity I pulled off the side of the road and called to have my vehicle towed to a service facility. I was informed by the mechanic that scanned my car for trouble codes, a P0336-00 was set in my PCM. The mechanic informed me that I would have to take the vehicle to a Jeep Chrysler dealer. This is apparently a known issue with 2014 to 2018 Jeep Grad Cherokees equipped with the 3.0L diesel engine including RAM 1500s of the same vintage with the same diesel engine installed. The specific problem is that the crank shaft tone wheel is not read by the crankshaft position sensor because of degradation to the tone wheel which is connected to the crankshaft. I have complied with all safety and emission recalls. Related: RC-RW68-20 Safety Recall W68 Transport Canada 2020-371 Loss of Crankshaft Position. Requires the replacement of the Tone wheel. Issued 02/11/2021. RC-RW58-20 Safety Recall W68 Transport Canada 2020-371 Loss of Crankshaft Position. Requires PCM Software update for Loss of Crankshaft Position. In lieu of the Tone Wheel failing, the computer uses the Camshaft Position sensor. This is only designed to not disable the car completely but allow the driver to pull of the road. P0335-00 or P0336-00 wil be set and a check engine light will illuminate. My vehicle was not included in the NTHSA Safety Recall and it should have been.

The SRS airbag light keeps coming up and does not show up as an error when a diagnostic is run on the car and they need to pull tge system apart to figire iut what the issue is. Secondly the capless gas tank nozzle keeps falling off.

The drivers headrest spontaneously exploded while we were driving and hit the driver in the back of the head and created a loud gunshot noise that startled us. When we stopped to inspect the headrest, the plastic clips that held it in place had snapped. We were not in a collision, nor did we hit any significant bumps. His head was not even touching the headrest when it occurred.

Car stalls without warning. Car is able to cruise and brake until I can pull off to the side of the road. Car will restart after turning it off. Speed, time, duration of the drive does not matter. It happened at 40 MPH, 60 MPH, 80 MPH. It happens 5 minutes into a drive or 20 minutes. Took it to the mechanic multiple times, codes do not pop up. Engine light does not come on. Mechanic is unable to find the problem.

The contact owns a 2015 Jeep Grand Cherokee. The contact stated while driving at 10 MPH in a parking lot, the vehicle unintendedly shifted into neutral. The contact stated that the RED caution warning light illuminated, and a message was displayed that the vehicle going too fast for the gear. The vehicle shifted into neutral independently. The vehicle was taken to the dealer however, there was no diagnostic test provided. The dealer stated that the vehicle was repaired; however, the failure reoccurred twice. On another occasion, after the vehicle was repaired, the vehicle shifted into neutral independently and the vehicle rolled backwards. The vehicle remained had been with the dealer since March 26, 2025. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 112,000.

Lifters are ticking. Yet another 3.6L Pentastar engine with the same issue, and no recall issued. Someone is going to die from this defect, if there haven't already been fatalities related to this problem.

After a very long road trip, I noticed that the rear wheel well liners had come in contact with the rear tires. The contact was severe enough and prolonged enough to wear down the edge of the tires to the cords. Once I noticed the damage, I stopped driving the vehicle until I could get new tires. I do not have the tires but I took pictures and the wheel well liners still have a hole in them. Had I not noticed the damage, a catastrophic failure of the tire could have resulted with unknow consequences to myself or those driving near me. The wheel well liners did not come loose or detached from the vehicle. They somehow flexed forward and made contact with the tire. The tire/wheel did not flex or move rearward. This would have required major damage to the suspension of the vehicle and the vehicle would have been undrivable. My assumption is that with the very wet road conditions, the wheel well liners became very flexible but not enough to contact the tires. At highway speeds, due to the air flow around the vehicle, it appears that the lower quarter panels flexed inwards. This allowed the now flexible wheel well liner to flex forward, due to air pressure behind the wheel well liner, and make contact with the tire. Tire tires involved are not the stock make and model but were the stock size. I will be adding a small aluminum strip to the bottom of the wheel well liner to prevent this from happening in the future.

The monostable shifter shifts without pressing the button. Can be bumped out of gear while driving. Message on display reads "service shifter". Replacement is necessary.
