I specifically purchased a 2017 Jeep Grand Cherokee 4X4 to cope with winters in detroit, Michigan. However, after only two snowfalls the vehicle has slid four times on city streets and more significantly fish tailed on an I-75 off ramp. In no instances did the 4X4 system try to correct through or notify the operator. In one instance the ABS was able to safely bring me to a stop over the line at a four way stop intersection. This is behavior is unsafe for everyday expected driving scenarios. More should be expected of a model year 2017 4X4 vehicle sold in Michigan. Unsafe. I now need to spend $900-$1000 to remediate the situation by buying better tires than those provided by the oem.

The vehicle memory system is not working at all, we bought in 12/2016 and somewhere in 6/2017 it stopped working, if you know anything about cars the memory system controls many aspects of the vehicle that do not have anything to do with the seat, steering wheel, miorror's, and rds, it also controls engine functions and safety systems, air bags, seatbelts, brakes., why the vehicle learns your driving habits and when you use different settings for different drivers, now it has control over your vehicle and driving habits or another drivers habits. (I had a 15 overland that wouldn't sync the remotes to the memory settings after multiple atemts, I also have a 14 Ram limited that works just fine.) so this is an ongoing issue for the grandelay Cherokee lineup. Per say the system be lives it is working but hasn't moved your seat or thinks your seat is in an alternative position and you get in to an accident, and the safety system over or under reacts to protect its ocupants due to system errors, equipment malfunctioning, and vehicle coponents not communicating properly. This could end in a catastrophe and potentially injuries, death, and destruction of private property. Shortly after I bought the summit I was at the dealership with my Ram (regarding survice), a elderly gentleman brought his 17 gc into the service depth complain about the memory system not operating, I didn't think anything about it "but this old man can't keep up with technology and just needed assistance" I have also spoken to multiple gc owners at gas station's, parking lots, and random shops and almost every 2017 starts malfunctioning after about 1 to 6 months and does not fix/default on its own, I had rds issues on my 14 gc remedy hold both volume and tuner at the same time to reset the system, this didn't helpmy 17, I have a a point mentioned to have it looked at by the dealership.

I have experienced numerous instances of the vehicle remaining in run mode after I push the stop button to shut it down. This only occurs when the ess (engine stop/start) is enabled. My initial belief was that the ess was restarting the vehicle. Upon further observation, I now believe that the vehicle is ignoring the stop button input. I realized that this is a safety issue when the vehicle failed to shut down at a gas station and I refueled with the engine running. I failed to realize that the vehicle had not shut down due to excessive noise in the area. The vehicle fails to shut down under these conditions: 1.the vehicle is running and the ess is enabled. 2.I pull into a parking position and hold the brake long enough for the ess to begin the stop engine sequence. 3.I push the shifter into park as the ess is in the stop engine sequence. 4.I immediately depress and hold the stop button. 5.the vehicle fails to shut down. The vehicle will not shut down until the stop button is released and pushed a second. I estimate that this happens to me approximately 20% of the time I attempt to shut down the vehicle with the ess enabled. This never happens when the ess is disabled. I have taken my Grand Cherokee to the dealer and a star case was created at fca. This failure to shut down was demonstrated to the mechanic on my vehicle and on another Grand Cherokee from their lot. Fca acknowledged that the failure to shut down situation does occur as I described. However, fca has not indicated they are taking any steps to correct the problem. Fca seems to be indicating to me that the solution to the problem is that I need to be more careful. I do not find this to be an acceptable answer. I believe that the ess under engineered, under developed and lacks the sophistication needed to be safely used.
