2025 Jeep Grand Cherokee electrical system problems

“Suddden engine stalls/electrical shutdown while in motion, causing total loss of power steering and power Other incidents of while traveling at 65-70 mph on the interstate the vehicle suddenly suffered a power failure and dropped into a dangerously low gear at low speed. The engine wound up drastically, causing a severe spike in RPMs, but when pressing the gas pedal, the vehicle refused to move or increase speed.spedometer read 20 mph. I videoed this when it happened.”

“Car cut off while driving, again. Full dashboard started to flash, warnings, stated that there was no battery, no gas. I was stopped in traffic and managed to pull over and had restart the car. This is the second time that it has cut off while driving . The first time my toddler son was in the car in morning traffic and it cut off. This is an extreme safety hazard for myself, my family and others driving. The entire system failed. It was supposedly fixed before but the problem is still there.”

“Vehicle was unable to be shutdown and was locked in park. Can was not responding to turning off while in the garage and engine running. Since the vehicle was inside an attached garage, we were concerned about Carbon Monoxide getting into the house. No way to turn car off and had to involve police/fire department. Disconnected the battery terminal in the trunk which was unable to be opened, so we had to crawl through the side passenger door to get into the trunk. The vehicle is now at the dealer (Wilde Chrysler Dodge Jeep Ram, at [XXX] in [XXX]). No police report #, but CAD entry from officer in having to assist.”

“New vehicle failure to start on four occasions over approximately sixteen months due to overnight parasitic battery drain. Following the first incident the dealer replaced both the main and auxiliary batteries. Following the second incident the dealer tested and charged both batteries and performed software update to body control module (BCM). Following the third incident the dealer tested both batteries and checked codes. Following the fourth incident the dealer replaced both the main and auxiliary batteries. The incidents required towing or jump starting.”

“The transmission fails constantly when we are accelerating - approxx 50-58 miles per hour the transmission freezes & the RMP's stay @ 4-5 thousand for 20-30 seconds - it fails to downshift. This is extremely dangerous at any time & can cause a major accident if the vehicle is stuck & you need to stop! We have have left the car several times for this issue & they keep telling us they cannot replicate the issue. (We are older & we are given looks like we are nuts)”

“This vehicle has now experienced three separate incidents of sudden loss of propulsion while traveling at highway speeds, requiring it to be towed to the dealership on all three occasions. Each incident involved the same dangerous defect, and after each repair I was assured, the vehicle had been repaired and was safe to operate. Despite those assurances, the identical defect has continued to recur. This is not simply a customer satisfaction issue; it is an ongoing safety issue that places my family and every motorist around us at significant for catastrophic event. On May 12, 2025, I took delivery of my 2025 Jeep Grand Cherokee High Altitude. On June 23, 2025, the vehicle experienced its first sudden loss of propulsion while traveling at highway speed and was towed to Ryan Auto Mall in Buffalo, Minnesota. On January 5, 2026, the identical defect occurred again. The vehicle once again lost propulsion while traveling at highway speed and was towed to the dealership. From January 5, 2026, through May 13, 2026, my vehicle remained at the dealership for approximately four and one-half months while Stellantis and its authorized dealer attempted to diagnose and repair…”
