2024 Jeep Wrangler vehicle speed control problems

“NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) FORMAL VEHICLE SAFETY COMPLAINT Date: [XXX] Complainant: [XXX] Vehicle: 2024 Jeep Wrangler 4xe Sahara Manufacturer: Jeep / Stellantis Selling Dealership: Mohawk Honda, New York Purchase Date: [XXX] Mileage at Purchase: 17,092 miles Mileage at [XXX]: 23,144 miles Mileage at [XXX]: 23,328 miles Date of Safety Incidents: [XXX] Stellantis Case Number: [XXX] 1. Nature of Safety Complaint I am reporting two serious incidents of sudden and unexpected loss of propulsion involving my 2024 Jeep Wrangler 4xe Sahara. Both incidents occurred on [XXX], shortly after I picked up my vehicle from Chrysler Dodge Jeep Ram of Clifton Park, New York, following recall-related service. During both incidents, my vehicle abruptly decelerated from approximately 50 miles per hour to approximately 20 miles per hour while traveling uphill. During the second incident, another vehicle was following behind me and nearly rear-ended my Jeep. I am extremely concerned that this defect creates a substantial risk of serious injury or death, particularly when traveling on highways or in heavy traffic. 2. Vehicle Purchase and Initial Service…”

“I own a 2024 Jeep Wrangler 4xe Sport S that has experienced a significant and potentially dangerous reduction in propulsion power following the completion of Recall 68C (NHTSA Campaign 25V741000) by an authorized Jeep dealership. These problems began after the recall software update and were not present beforehand. Since the recall repair, the vehicle has substantially reduced electric-motor acceleration. While operating in Electric mode, pressing the accelerator can result in an increase of only approximately 1 MPH every 1–2 seconds, even with substantial accelerator input. The internal combustion engine (ICE) then engages prematurely at unusually high RPMs to compensate for the lack of electric propulsion. This results in delayed and inconsistent acceleration. Additionally, the vehicle struggles to accelerate beyond approximately 55 MPH while operating in Electric mode. When attempting to accelerate further, the vehicle eventually displays "Electric Mode Not Available" and disables Electric mode for the remainder of the drive. Before Recall 68C, the vehicle operated at highway speeds in Electric mode without these limitations. Despite these repeatable…”

“My Jeep Wrangler Sahara 4xe experienced a sudden and severe loss of motive power while making a left turn onto US Route 301 at a major intersection. When the traffic light turned green, I attempted to accelerate through the intersection, but the vehicle suddenly entered what is commonly referred to as “Turtle Mode” and would only travel approximately 2 MPH. This left the vehicle moving extremely slowly in an active major roadway and created an immediate risk of being struck by approaching traffic. I activated the hazard lights and had to make an emergency maneuver to move the vehicle to the right and out of the travel lanes. This is the FOURTH time this vehicle has experienced a sudden loss of power/Turtle Mode condition. The problem is intermittent and occurs without sufficient warning to safely remove the vehicle from traffic. Warning indicators/messages associated with the reduced-power condition appeared when the failure occurred. The vehicle was previously taken to an authorized Jeep dealership for this same recurring problem and remained there for approximately one month. The dealership was unable to determine the cause of the repeated Turtle…”

“1: Ever since one of the recalls was "addressed", the vehicle seems to lack power when taking off, etc. It seems like it lacks propulsion. 2: I was driving on the highway several times, and for no reason, the power reduces greatly and I am unable to go above 60 mph. The warning light (as seen in the attached) comes on and stays on until the vehicle is turned off. This has happened to me several times at different speeds (with and without adaptive cruise control on). I cannot seem to replicate this again, and, when the light comes on, it's been at times that I was unable to take it to the dealer with the light on. It sat at my local dealer for about 3 weeks cumulative as of lately, and they could not get the light to come on. They even got a TA to come out, and they couldn't find the issue or cause the light to go on. Keep in mind...this is a leased vehicle, and miles matter. I took the car back since I cannot continue paying for a rental (even though they eventually may reimburse me). I have had several issues with this vehicle throughout the life of the lease. I cannot wait to turn it in or possibly involve a lawyer for a lemon law issue. I cannot continue…”

“After 68C recall completed, there is a noticeable reduced power and sudden engine (ICE) starts when it shouldn't be needed. It takes seconds for the vehicle to pickup speed when needed such as when merging lanes which causes a high risk for an accident due to this delay in response. This vehicle is not running as intended, it seems the threshold has been reduced on purpose which is not why I purchased this vehicle to begin with. I need this vehicle to operate as it once used to. Since there has not been a code produced dealer is not able to help. This is not a one off I know other consumers are running into the same situation something needs to be done to resolve the root cause of the problem and not mask it while changing the vehicles original specifications in terms of performance.”

“Driving the vehicle and it had uncontrolled acceleration. The wipers went on and multiple lights went on, engine, brakes to name a few. The brake peddle did work. Picture below was after incident and not all the lights.”
