Electrical issues- been to the dealer 4 times with no resolution Radio turns to max volume while trying to lower sound. Air/heat turns on and off by itself while driving.

AC/HVAC: experienced multiple occasion where the system (front and rear) turns on and quickly varies between settings with no way to override. Engine: when speeds are in excess of 80mph front passenger vent makes excessive noise in line with engine rpm’s “Auto drove” ineffective due to lane departure inop, after service for above incidents Radio is extremely intermittent.

Vehicle has a malfunctioning climate control system due to electrical / software issues. When the climate control a/c is set to manual mode it will have a "ghost" control which will randomly change settings, it changes the set temperature - recirculating mode - a/c on and off - fan speed - fan direction (windshield, face, feet) - and will also apply to the rear passenger control unit. The main and lower front climate control screens will act "crazy" when this "ghost/glitch". is happening and randomly change settings, the driver cannot override it when it is happening until the vehicle is shut off. It is extremely dangerous as this malfunctioning climate control will let the front windshield moisture build up and be impossible to clear off - which leads to a visual obstruction and could result in a crash, it's especially bad for us in the PacNW in the winter when it is dark and always wet, not being able to keep the windshield clear is scary. I've reported the issue date as 12/24/22, but it happens frequently. I have recorded videos of it happening on my iPhone but the file size is too large for here. We are still waiting for parts from Jeep to get this issue fixed, there are multiple reports from other owners on this issue also, why is this vehicle allowed to be sold to the public ? It has so many issues.

While I was driving at around 35 miles per hour and tried to stop in a short distance because of the “should I go or not” situation at the traffic light, the whole vehicle was shut off at a blink of an eye. Soon after I noticed it and tried to imitate the incident to make sure I wasn’t mistaken, it happened three time in a row. The incident can only be seen at night time when light from the headlight is visible since it happens so quick. It wasn’t just about headlight. The engine shut off and turned back momentarily as well. Thankfully each event didn’t last longer than a second and there weren’t any vehicles nearby. When I told a CDJR Monrovia service department manager about the incident and said we need to investigate, he was not serious about it. And nothing was inspected upon the request. There were no warning signs prior to the failure.

Complaint - The wiring harness in my engine compartment is mounted on the firewall below the cowl. It runs from the driver’s side to the passenger side. On my vehicle, it has a significant drop on the driver's side, almost hitting the master brake cylinder cover. The wiring harness does move significantly on the driver's side. Note-Some kinds of clips are molded onto the wire harness cover. Upon inspection of the wiring harness and cover, there is nothing that I and Service Director could find to attach the wiring harness to the firewall to keep it permanently up and away from the driver-side master cylinder brakes. Notes - My vehicle is available to you for inspection if warranted. -Dealership Service Mgr Director and Wagoneer customer service were notified and were inspected. I/we also confirmed and noted that other identical vehicles have the same problem. — inspection was performed either on the service lot by Director and myself or in the Dealership Showroom Display vehicle by me. -WCS officially informed me on 7/8/2022 that the Service Director said my vehicle wiring harness was manufactured as designed, and WCS goes by what the Director says. Because I told them (WCS) I was filling a complaint with NHTSA, they will close my case. -As of this date, no problems or failures are noted. Impression- This potential safety hazard could lead to electrical shorts, major components failure, and a possible fire hazard when the vehicle is in motion due to vibration wear, including off-road use.
