2026 Jeep Grand Cherokee Electrical Problems

While driving the vehicle, it completely shuts down unexpectedly. This issue is not related to the auto-start functionality. When the vehicle dies, it goes completely dead. The first time it happened, it restarted on its own but shifted into park and activated the emergency brake. During the next two occurrences, the vehicle also shut off, and I had to manually restart it. No warnings or anything; it just completely goes dead. This puts me and my family at risk. The car can shut down on a major highway suddenly, causing a multi-car accident or, worse, a fatality. The vehicle has been to the dealership (Chrysler) the first time I was told its because my battery is dead, but since I am below 80%, Chrysler will not replace the battery so the batteries were recharged however I was told I will be back for replacement batteries eventually. The second time, the technican drove the car home (it stayed over night) and the car shut down on him while he was driving also. Chrysler says this only happens when I jump start my car and its not a manufacture issue. The result in this visit is my engine blown a 150v bold (something) and this is causing the shut off. Chrysler refused to fix saying Its not including in warrent since I only have 7k miles. The dealership took the cost and repaired the car. The third time it happened, Im still waiting for the dealership. I have not taken the car for the third incident. This issue has been confirmed by the dealership (seen twice ) and the manufactor (Chrysler)

New 2026 Jeep Grand Cherokee (2.0L turbo I4) has open, unrepaired safety recall 26V-559 (FCA 54D): the tire pressure monitoring system may not detect low tire pressure or illuminate the warning telltale; remedy is an RFH module reprogram. The vehicle also has an open manufacturer campaign for 2.0L engine spark plug replacement and additional software flash campaigns. I scheduled service for these recalls at an authorized FCA/Stellantis dealer (Larry H. Miller Chrysler Jeep Dodge Ram, Boise, ID). I dropped the vehicle off on a Wednesday at 7:00 AM; the dealer kept it nearly 4 full days and returned it Saturday evening with zero recall work performed, citing shop scheduling delays. The service advisor told me to call/email the following Tuesday to reschedule; those calls and emails were not returned. Voicemails and emails to the dealership's service manager and general manager have also gone unanswered. As a result, I am driving a new vehicle with an incomplete safety recall and no dealer remedy scheduled. No crash, fire, or injury has occurred. Problem has not been inspected by the manufacturer. I have escalated to the manufacturer and am attempting to book the recall at an alternate dealer. I am reporting that the manufacturer's dealer network has failed to remedy this safety recall in a timely manner.

driving down the road at any speed, the jeep will stop on a dime like you applied the full brake and shut off. i this has occurred 4 different time almost causing 2 bad accidents, one involving an unloaded log truck on hwy 130 in nc and the other one on hwy 544 in sc. The other two were while trying to accelerate out onto the rd. All this occurs without any warning. The engine will race quickly up to 35mph making rpm go to 7, the dash will go completely red when pulling off at red lights. I refuse to drive it thru a small town where people cross at, Jeep has been reported back to dealerships for all the same reoccurring problems since 130 miles.. Spark plugs replaced 2, elec parts been replaced , nothing is fixing the problem. MB Jeep is where i purchased the Jeep. Will not hold a speed, it will control speed itself. I took it back Saturday to dealership, bc I refuse to get killed or kill anyone else with all these problems. I was also told that my jeep of the 26 model engine change out was no the only one. All of them are coming back in with major problems.

2026 Jeep Grand Cherokee Limited - Once I shut down engine, when I opened the door to exit, it started beeping at me. After a few minutes looking around to make sure I hadn't left a door open or something, I thought maybe it hadn't registered that it was in Park, and Shut Off. I pushed the "Start" button, and the dash had a message "Ignition On". When I tried to put it in Reverse, it moved on it's own back into Park, and again displayed "Ignition On". I tried putting it in Drive, and the "D" just flashed at me and finally moved back to "P". I'm not sure exactly when this was displayed, but there was a message at one point that said something about the "Start/Stop" function, but it wasn't visible long enough for me to catch what it said. I called my son who came over and we troubleshooted (I was afraid to remove my foot from the brake due to other horror stories I've heard about, so I sat there for several minutes with my foot on the brake waiting for my son to hopefully know what to do). Once he was there, he asked me to slowly remove my foot from the brake. When I did, he could feel the Jeep trying to move forward. After some other testing/troubleshooting, he asked me to lock the door and see what happened. I did so, waiting a few minutes and turned it back on. This time it worked as expected and started. I'm driving this car all the way to Texas next week, and I'm terrified (especially now that I see ANOTHER recall - that's 3 since I bought the car 60 days ago) that something horrible is going to happen! I do not feel safe in this car, and I just spent ALOT of money on it!
