On June 18, 2026, I was driving my 2024 Grand Wagoneer on a busy city road. As I approached a busy intersection, I stopped at the red light. When I attempted to move forward when the light turned green, it moved a few feet (putting us in the middle of the intersection), the vehicle seized and became immobile. Almost every light on the dashboard lit up. Several messages flashed back and forth on the screen including "Service transmission" and then "service electronic stability control". I immediately tried to use the SOS function, and when they answered, they were unable to hear me. A person in a truck behind me told me to put my vehicle in Neutral so that the vehicle could move out of the road as it was blocking traffic. When I tried to turn the gear dial, it turned, but the P light stayed on and the vehicle would not go into Neutral. I checked the parking brake and it was not on, nor would it engage. The vehicle being stalled, with zero ability to move put my children and I in danger as there was not a safe place to even exit the vehicle as traffic was completely surrounding us. I tried to turn off the vehicle, but the vehicle stayed in the "run" function even after being pressed. Emergency services was my only next choice. One more push of the off button and the vehicle finally turned off. I waited for 2 minutes and tried to turn the vehicle on again. It did turn on, showing the check engine light. I then was able to put the car into gear, and it moved. I moved the vehicle out of traffic to the next available parking lot. I immediately contacted the dealership and told them I would be having the vehicle towed there for inspection and I do not feel comfortable driving this vehicle again. Unfortunately, this is the 3rd time my car has put me in a dangerous situation in the middle of an intersection, the other 2 being false crash alerts (turning left in turning lane and car thought I was going into oncoming traffic).
NHTSA complaint #11745417 — an unverified report by a vehicle owner.
Incident: Frontal collision with a boulder at 30 MPH. 1. Component/System failure & Inspection Availability The primary failure was the Supplemental Restraint System (SRS); the driver’s frontal airbag failed to deploy during a high-energy frontal impact. Additionally, Advanced Driver Assistance Systems (ADAS)—specifically Forward Collision Warning (FCW) and Lane Departure Warning (LDW)—failed to provide alerts or initiate emergency braking prior to impact. 2. Safety Risk The failure created a life-threatening risk. Striking a boulder at 30 MPH caused substantial structural damage, requiring total replacement of the front-right and rear-right suspension assemblies. Despite the severity of the impact, the airbag remained dormant. The lack of FCW/LDW intervention meant zero mitigation was provided to prevent the roadway departure or collision, rendering primary safety features non-functional. 3. Confirmation of Problem The fact that the airbags did not deploy was confirmed by independent inspection following the collision. Assessment of the vehicle damage shows that impact forces were clearly sufficient to trigger the SRS, yet the system failed to activate. While ADAS failure is a dynamic event, the total absence of system logs or alerts during the crash sequence confirms the electronic malfunction. 4. Inspections Performed The vehicle was inspected by an insurance adjuster and collision repair professionals. These inspections documented that the impact was severe enough to cause significant mechanical failure, yet no airbag deployment occurred. The manufacturer (Stellantis/Jeep) has not yet performed a formal data download (EDR) or physical inspection. 5. Warning Lamps & Prior Symptoms No warning lamps, SRS/Airbag indicator lights, or "Service" messages appeared prior to the failure. The diagnostic interface indicated all systems were "Normal," pointing to a catastrophic "silent failure" of the sensors or the Steering Column Control Module.

I am writing to formally document a serious and extremely concerning safety incident that occurred on Wednesday, March 4, 2026 at approximately 12:06 PM while driving my 2024 Jeep Wagoneer, which currently has approximately 58,000 miles. While driving, multiple critical warning lights and system failure messages appeared simultaneously. I have attached photos documenting the warnings that occurred during the incident. Service Power Steering • ABS warning • Red steering wheel with exclamation mark • Check Engine Light • Collision / Auto Emergency Braking warning • Traction Control / Electronic Stability Control Warning • Forward Collision Warning / Automatic Emergency Braking Disabled During this event, the vehicle behavior became unpredictable and unsafe. Considering the failure of multiple safety systems at once, this created a situation that could have easily resulted in a serious accident. I am extremely shaken by the experience and thankful that my four children were not in the vehicle with me at the time. Unfortunately, this incident is part of a long list of issues I have experienced with this vehicle since purchasing it. These include: Persistent check engine light issues • Replacement of all third-row seatbelts due to defects • Oil valve replacement (Code P06D – Oil Pump Control Stuck High) • Multiple software updates • The vehicle shifting itself into park when coming to a stop, with the gear dial locking and requiring the vehicle to be fully shut off and restarted before it can be driven again • Driver window intermittently sticking • Replacement of the passenger seat massage system due to an air bladder malfunction • Vehicle jolting/jumping when coming to a stop Given the number of ongoing mechanical and electronic problems, I no longer feel confident that this vehicle is safe to drive. I purchased this vehicle specifically for the safety and reliability.

Blindspot indicator keeps turning on and off, distracting the driver. Have taken vehicle to dealer many times they say it can’t be fixed even though it was during Warranty. They say a jeep is aware, but no plan to fix.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The vehicle has ongoing electrical and battery system problems that cause safety and driver-assistance systems to malfunction or shut off unexpectedly. The vehicle has repeatedly been found dead after short periods of non-use, requiring jump starts and battery replacement. These electrical issues appear to affect multiple vehicle systems simultaneously. While driving, advanced safety features such as lane departure warning, lane keep assist, adaptive cruise control, and proximity-based warning systems shut off, become unavailable, or behave inconsistently without warning. In some cases, warning messages appear and then clear on their own, while the affected safety systems remain disabled. At other times, the systems deactivate without any clear alert. The manufacturer and dealer have acknowledged battery drain and electrical instability, but instead of permanently repairing the underlying problem, certain features were disabled to reduce battery draw. These include proximity-related features and other driver alerts. Disabling safety and warning systems does not correct the defect and creates an unsafe condition where the driver cannot rely on the vehicle’s advertised safety features to function consistently. Because these systems disable themselves or are intentionally disabled due to unresolved electrical issues, the vehicle cannot be relied upon to provide continuous lane-keeping assistance, collision warnings, or adaptive cruise functions. The failures are unpredictable and occur during normal operation, creating a safety risk to occupants and other drivers.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Assessment of Ongoing Mechanical & Safety Issues – 2023 Jeep Grand Wagoneer To Whom It May Concern, I am providing a clear, factual assessment of the ongoing issues with my 2023 Jeep Grand Wagoneer, which I purchased for $108,000 and have owned for less than two years. During this time, I have experienced twelve separate mechanical and functional failures, several of which have rendered the vehicle undriveable for prolonged periods. Below is a summary of the major issues that continue to impact the reliability, safety, and usability of this vehicle. 1. Seat / Massage Mechanism Defect (Ongoing for Months) A malfunction in the seat massage system has created a large, hard protrusion in the driver’s seat. This defect has resulted in significant back pain, requiring both urgent care and follow-up medical evaluation. I have now been diagnosed with sciatica, which my physician has indicated is likely related to prolonged pressure and improper spinal support caused by the seat malfunction. Two dealerships have confirmed the issue and ordered the replacement part months ago, yet the part delivery has been repeatedly delayed, most recently to January 6, 2026. This has affected my ability to safely and comfortably operate the vehicle, and has now escalated into a documented medical issue. 2. Suspension Noise During Auto-Leveling The vehicle’s air suspension system produces extremely loud noises during auto-adjustments. This raises concerns regarding the safety and structural integrity of the suspension system. 3. Window Hinge Failure A window hinge has prematurely failed, requiring service intervention. This is not consistent with typical wear for a vehicle less than two years old. 4. Cruise Control Malfunction The cruise control system intermittently ceases functioning while driving. The only way to restore it is to turn the vehicle off and restart it, which presents a safety concern when traveling at highway speeds. This points to a possible electrical or
NHTSA complaint #11702289 — an unverified report by a vehicle owner.
AEB system engaged emergency braking for no apparent reason when traveling at >35mph on a busy road with the flow of traffic. My face actually hit the steering wheel and a car traveling behind me barely stopped in time to avoid rear ending me. The AEB system has repeatedly displayed warning lights in the dash previously. For each occurrence, the vehicle was serviced at the dealership and reassurances were provided each time that the underlying issue was remedied with reprogramming and/or replacement of electrical control modules, however the recurrent nature of the issue (and many other issues surrounding the electrical system in my Grand Wagoneer) doesn't instill confidence in the "fix" they're providing. At this point in time, I don't feel safe driving my Grand Wagoneer, as I don't know when the vehicle will involuntarily slam on the brakes in traffic and cause an accident.
NHTSA complaint #11690105 — an unverified report by a vehicle owner.
This issue happened 3 times in a matter of 2 months. All 3 happened in 3 different intersections. While turning left in the intersection (oncoming traffic also turning left) the vehicle jerks to a full stop in the middle of the intersection with a "Crash Detected" message flashing on the dashboard screen. The vehicle stayed in DRIVE and continued to drive after full stop the first 2 incidents. On the 3rd incident, the vehicle stopped completely, and would not continue to drive. The vehicle had to be put into park (even though it said it was in drive but did not drive) and put into drive again to continue moving. Other vehicles driving behind the Grand Wagoneer were required to slam on brakes to prevent impact of the Grand Wagoneer and had to wait for the Grand Wagoneer to begin driving again. Unable to drive this vehicle due to safety issues. The vehicle is currently in the shop under investigation.
NHTSA complaint #11686079 — an unverified report by a vehicle owner.
I purchased this vehicle 04/15/2025. Starting at less than 500 miles the Blind Spot Indicator Warning Lights along with the ABS Braking System Warning Lights randomly come on while driving. To receive random warning light notices and sounds while driving is extremely startling and concerning. I have taken the vehicle to the dealership multiple times with no success of fixing the issue. They have been in touch with Chrysler’s engineers. The engineers have given instructions such as inspecting the electrical system, replacing the main module and software updates all of which have not corrected the problem. The vehicle is still at the dealership with no resolution. Apparently, these issues have been reported before not only for the Jeep Grand Wagoneer but other Chrysler vehicles as well. As a loyal Jeep customer, I purchased this vehicle because of the safety features advertised. However, it has become a nightmare and I do not feel safe driving in this vehicle at all. Please research these safety concerns.

While driving my 2023 Grand Wagoneer the Serv 4WD light and dash spelled out Service four wheel drive, it lit up the anti collision light, ECS, TCS, and HOLD!. The parking brake also engaged automatically while driving at least 4 times. This is a serious safety concern to allow a vehicle to continue driving with the ability to automatically engage the parking brake while driving. The safety of my entire family was put at risk. I currently have the vehicle sitting at the dealership to be diagnosed and reproduced as the vehicle lost all power after this incident. Another serious safety concern is the total loss of power with no notice. This could easily have been while I was driving and caused a serious accident and possible fatalities.
NHTSA complaint #11673436 — an unverified report by a vehicle owner.
Airbags failed to deploy in a front crash. Passenger side curtain air bags deployed, but none of the others deployed. The lane departure or lane keeping assistance did not work. The vehicle slowly swerved off of the highway with no safety features kicking in to help keep it on the road. No automatic emergency braking started. The vehicle was still going with the cruise control on following the collision. As of 3/20/2025 the vehicle is still available for inspection. This is the first report of this malfunction. The local sheriff was contacted following the accident. I do not have knowledge of who all has inspected the vehicle. There were no warnings or messages that the safety systems were not working. Yes, our safety was at risk. As the driver of the vehicle, I have broken my C2 vertebrae in my neck.

While driving the vehicle(speed does not matter as this has occurred while standing at a stop light) all safety warning lights illuminate on the dash and render all of my safety features inoperative. This includes: ABS, Forward Collision Avoidance, Rear Collision Avoidance, and Park assist. Once this happens the vehicle becomes extremely difficult to operate and to stop. The remedy is to pull over, turn the vehicle off and open the drivers side door to shut off the RAC (Retained Accessory Control), let the vehicle sit for a minute or two, then restart the vehicle. All light will remain off and the car will function normally. This issue occurs at least 2-3 times per week and is extremely frustrating. I've taken the vehicle to the dealership several times for what they have determined to be a "software issue". Several trips have been for recalls, others have been for this issue and my Infotainment system going black. The Infotainment system going black is the second major issue with this vehicle. The dealership was able to get the system operating again with an additional software update, however it has not completely remedied the problem. The Infotainment system will still black out, but for only a quick second, then it comes back on. When it does this, I loose all settings including profiles and SiriusXM programmed stations. I've done a master reset on the Infotainment system and have had it back to the dealership, but it still has not been 100% resolved. This is a safety risk when it blacks out as I loose navigation, audio, and Bluetooth connectivity. Now my attention is not on the road but on the failed system.

The vehicle came to a screeching stop with no visible reason for doing so. Three cars behind me also had to come to an abrupt and dangerous stop to avoid me. I pulled out of my driveway, began to drive, reached 10 mph, then came to a full brake, causing tires to screech. The speed of traffic behind me was approx 25mph.
