2024 Jeep Wagoneer

My 2024 Jeep Wagoneer L with the 3.0L Hurricane engine began experiencing drivability and warning-light failures at very low mileage and within the first year of ownership. The vehicle was purchased new in October 2024 and experienced its first major drivability/towing event at approximately 10,372 miles. Over the following months, the vehicle experienced repeated check engine light events, shaking, sputtering, hard starting, loss of throttle responsiveness, drivetrain hesitation, and multiple towing incidents despite repeated dealership repair attempts. The most severe safety event occurred in May 2026 at approximately 18,850 miles while traveling on the interstate with my family and young children. Prior to this event, a Florida Jeep dealership documented diagnostic codes P21A0 (Cylinder 5 Air/Fuel Ratio Imbalance) and P0430 (Catalyst System Efficiency Below Threshold) and specifically documented in writing that “the #5 fuel injector is causing the fault” and likely damaged the catalytic converter. Despite this, we were advised the vehicle should be safe to drive home. While driving on the highway the following day, the check engine light began flashing and audibly beeping continuously, the vehicle began shaking aggressively, and acceleration responsiveness deteriorated significantly while traveling at highway speeds. We were forced to immediately exit the highway and abandon the vehicle at a Jeep dealership in Georgia due to safety concerns and fear the vehicle could become unresponsive in traffic. The vehicle has been inspected multiple times by authorized Jeep dealerships in South Carolina, Florida, and Georgia. Earlier repair attempts attributed the issues to software/update-related causes. The Georgia dealership later replaced the catalytic converter but did not directly address the injector-related concern because the condition was not actively reproducible during their inspection despite the prior dealership’s written findings.

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.

Vehicle is 4 months old and has 2300 miles on it. Randomly and suddenly the vehicle will lose power while in traffic. No steering or engine power. It will abruptly coast to a stop, put itself into park, and stall. Several lights will come on. All the lights but the check engine lights disappear after letting the car sit. The car sometimes turns over only to stall a few seconds later. If left to sit for 30 minutes or so, it will drive again. Obviously a car that shuts off and loses power while driving is a big safety issue. I am unsure if I should drive it again, in case it happens at the wrong time. This has happened on three occasions over the last 350 miles. 5/6/24 5/22/24 6/15/24 The vehicle has spent over thirty days at the dealer. They do not know how to fix it. On 6/15/ 24 one of the owners of the dealership was able to see the mechanical problems 1st hand.
