I am writing to formally submit a dangerous and sudden electrical system failure on my 2024 Jeep Wagoneer. I purchased this vehicle brand new from Lee Jeep in Wilson, NC and it currently has only 38,000 miles—just 2,000 miles past the standard factory bumper-to-bumper warranty. This issue represents a severe safety hazard and appears to be a direct, consequential chain reaction resulting from a dealer-performed service and software flash completed just 1,000 miles ago. Chronology of Events: 37,000 Miles: The vehicle's thermostat failed. Lee Jeep replaced the thermostat and performed a required computer system software update. 38,000 Miles: Immediately following these updates, the vehicle began completely shutting down and stalling at stoplights and stop signs. Simultaneously, the Electric Power Steering (EPS) completely cut out, leaving me stranded in active traffic with heavy, unassisted steering. Current Status: The dealership diagnosed a blown main engine fuse and is demanding $450 to replace it. They have refused to cover this under a goodwill adjustment, claiming their local branch "cannot do it." A full vehicle shutdown and loss of power steering at intersections puts my life and the lives of my passengers at immediate risk. Unresolved Root Cause: A high-amperage engine fuse does not blow without an underlying cause. I am deeply concerned that charging $450 to swap a fuse without diagnosing the systemic current spike—likely tied to the recent software update or the auxiliary stop-start battery logic—will leave me stranded again. Proximity to Warranty: Given that the vehicle is a 2024 model and barely past the 36,000-mile mark, a catastrophic electrical failure of this nature should be covered by the manufacturer.

The engine shuts off unexpectedly when the automatic start stop system engages. At the same time the engine shuts off, the power steering warning light illuminates and steering assist is lost. The vehicle must be restarted to regain power steering and continue driving. This has occurred on multiple occasions, including while the vehicle was slowing to a stop in traffic. The sudden loss of steering assist while the vehicle is in motion presents an immediate safety risk to the driver, passengers, and surrounding traffic. This appears to be a widespread issue. Other 2024 Jeep Wagoneer owners have reported the same combination of symptoms, sudden stalling paired with power steering warning lights, in complaints already on file with the federal safety agency. Suspected causes reported by owners and dealers include a failing 12V or auxiliary battery, a Powertrain Control Module fault, and a Power Distribution Center or wiring fault.

My 2024 Jeep Wagoneer Series 2 frequently stalls while coming out of idle, such as at traffic lights. This is not the auto stop-start feature and happens whether or not auto stop-start is deactivated. Usually, after being by stopped, as I am getting ready to start moving again, the vehicle will slightly rev or try to lurch forward before stalling out. This turns the engine off, throws the car into park, and activates my e-brake. It happens before I press the accelerator so the car is not moving more than a mile or two an hour. This problem is dangerous because it creates a risk of accidents with other vehicles. When the car stalls in this way, I must confirm the car is in park, press the brake, restart the engine, deactivate the e-brake, and shift the car into drive before proceeding through the intersection. This takes a few seconds and if the driver in the car behind me isn’t paying attention and think I am starting to move, he or she could rear-end me. This problem has happened more than a dozen times (so not every time I drive but frequent enough to be a pattern). It can happen when I have been driving for a while and the engine is warm. There is no way for me to predict in advance when it will happen. It can go weeks without happening or happen twice in the same day. It does not activate any dash warnings (such as service engine light or an error code) that I can see. I have taken my car into the dealership twice for idle related issues including once for this exact problem. The last time, the dealership found misfires on all cylinders, both catalytic converters coming apart from the inside and 02 sensors that had melted from overheating. The dealership replaced all of this. My vehicle still stalled on the way home from the dealership. This time, I detected a strong rubber or plastic burning odor when I got home. The vehicle has less than 12,000 miles on it and was bought new less than a year ago. I attach last repair invoice.

This vehicle has presented a myriad of electrical problems as follows: 1. Glitching in the central display panel. Slow to turn on, flickers at times. 2. ALM (Active Lane Management) system randomly and suddenly turning off. Often unable to turn the ALM system back on while driving. The same issue with the Adaptive Cruise Control system. 3. Vehicle sensors showing "unavailable" on the driver's display screen. 4. Vehicle was completely dead due to both batteries dying (main and auxillary) 5. Engine ran hot after a short period of time. Temperature reached as high as 253 degrees, then the engine overheating sign came on, followed by Low Oil pressure notification. Oil pressure dropped to at least 21 psi 6. There were no warning messages prior to any of these incidents occurring. 7. Auto Emergency Braking (AEB) would randomly engage for no apparent reason. 8. ALM unavailable service required message would randomly show up. 9. Front passenger screen would not come on, when the screen had seldomly been used. 10. The engine jumps every so often while driving. This is unrelated to the engine automatice stop feature when the vehicle is stopped. 11. A/C system is faulty. The "auto" button does not automatically adjuster the temperature or the fan speed when it is in use. I've had this issue since I purchased the vehicle. Reported to dealership more than once and it's still unresolved. 12. Driver's side window will remain stuck in the down position after window has been lowered. You have to turn the vehicle off and on for this to reset and window starts to operate again. Dealership cannot duplicate and this has happened more than once. 13. Stop/start not ready engine temperature too low message would randomly pop up at times. 14. When engine cranked, various dislay signs appeared on the driver's panel and would not allow me to use the brakes. 15. The vehicle has been in the shop since July 11th. No loaner vehicle was provided. Incidents cover various dates.
