The HID headlights failed and is available for inspection. Can't drive in the dark or rain, less visible to other motorists. Yes, confirmed by dealer. No other inspections. No notices were given. My friend noticed it and we drove home from an event at night with running lights. Numerous other Jeep Grand Cherokees have the same issue and do have the recall and repair available, but for some reason the Summit was overlooked and should be placed in the recall ASAP. Clearly, this is a Jeepwide problem and not limited by VIN number.

The vehicle had a complete shutdown while being driven. While driving on the highway, several dashboard warning lights began to appear. Within seconds afterwards, the headlights went out, along with the dashboard lights and radio. The vehicle became difficult to steer and then the vehicle lost all power, and could not be restarted. The vehicle was picked up from the dealership the day prior to this occurrence, and the PCM had just been replaced. The vehicle had been towed to the dealership just short of two weeks earlier, after it wouldn't start, having replaced the battery, and experiencing the passenger front window to randomly go down. This incident fortunately did not result in any crash or injury, however, it is only a matter of time if it isn't correctly diagnosed and fixed, as this problem results in an extremely hazardous condition.

While driving on a highway at 60 MPH my vehicle started flashing every possible warning light. Airbags, ABS, slip control, cruise control ... Everything. Most concerning was the 'service shifter' alert; the prnd lights on my shifter panel all started flashing and the car (auto transmission) was stuck in one gear and would not shift. Pulling over and restarting the vehicle would 'fix it' for 10-15 minutes until it all happened again. Engine was making an awful loud noise so I pulled over again. This time after turning it off the vehicle would not start at all. After 30 minutes it started and I was able to drive to a town for the night. The next morning I was able to start it and drive it in 1st gear (where it was stuck) to a jeep dealer. There it sits as I type. I have seen many identical issues reported by jeep owners on internet forums and most worryingly, jeep dealers don't seem to have a clear answer. They're commonly replacing the shifter wiring harness but the problem returns for nearly everyone. This incident stranded me in the middle of the night, in the middle of nowhere, and left me very worried about my safety. Whatever is wrong with the vehicle has cascading errors that affect headlight operation (my high beams would now work), slip control (it became non functional even if I overrode it), wipers (in my case they came on without any rain and I could not turn them off...they could just as easily have not functioned in a downpour creating a safety hazard), and braking (the brake pedal was rock solid and not working properly).

For the second time, I was pulled over by the state police because my tail lights were not on at night. In both cases, it is likely that when I got out of my jeep my knee brushed the dial that controls the headlights and moved it from "a" to "o" (auto to off). Both times it was after dark and because of the daytime running lights, it was not immediately clear to me that the headlights (and taillights) were not on. In both cases, the trooper let me off, but this seems like a design flaw that could create a major problem if a car were following me and did not see me.

On most newer cards the dashboard is digital and back-lit. Some of these cars also have very bright daytime running lights. What I have seen is that some owners inadvertently turn off the auto lights, and think they have lights on because they can see where they are going, but they lack any rear lights because the lights are not technically on. I've seen this in jeep vehicles as an example. The only way to know your lights are on in a jeep for example is a little green headlight icon, that is easily ignored. Something more needs to be on the dash when lights are in the off position at night.
