I took my 2021 diesel Jeep in for a Y81 Emissions recall on 02.19.24. Since then, my vehicle has had its check engine light go on SIX TIMES with a P0133 alert which refers to an O2 sensor. I have taken it in to the dealership for a resolution six times. Currently, it is set to be diagnosed and repaired yet one more time on 01.22.25. Now we are in the middle of winter and I feel like the vehicle is about to die at intersections and roundabouts when I approach them. I tried to go through an arbitration with FCA USA LLC which produces the Jeep brand and it was denied for a repurchase of the vehicle because the arbitrator felt it was not a safety issue since I still drive the vehicle and they are technically not in violation of the warranty which I did not accept as a resolution. Due to my non-resolved safety concern, I am raising the issue in this forum so hopefully something can be done and others that potentially have the same issue can reach a resolution as well. My hypothesis of the cause of the issue is when the Y81 recall happened, it tuned down the emissions output that was originally higher necessary for the vehicle to run, because I didn't have check engine lights before. By this tune-down of emissions, the engine is not able to produce the correct output to run the vehicle and thus the random lack of power causing a safety issue, and is currently adversely affecting components that are causing the P0133 O2 sensor to alert.

The engine and cluster showed and made noises indicating that the hybrid system was malfunctioning. The cluster indicated a speed limit at high speeds, but never did so. The electric drivetrain was disconnected and the handling and power were severely affected. It was dangerous because the distracting and concerning issues were during a rapid speed and in dangerous conditions with no clear remedy. The check engine, red turtle, and battery lights indicated the problem, but not beforehand. There were some warranty fixes around the battery including recall work.

Recent recall 95B was performed December 15th, 2024 on my Jeep 4xe. The vehicle passed the road test involved with the safety recall to detect a defective high voltage battery. On December 26th, within 100 miles of the recall test being performed, the vehicle cruise control involuntarily shut off, check engine light illuminated and the vehicle lost power on the freeway. We were able to return home with the vehicle lurching while driving, having erratic acceleration from a stop and pushing through braking. The issues continued a few days later when delivering to the Jeep service center and the Jeep died in the service lane and had to be pushed the rest of the way to the service bay. The "fix'' that Stellantis has provided seems to simply later detect the battery issue that the recall test was designed to detect under their care during the test procedure. There are numerous other 4xe owners that I am aware of that are having the same post-test failures and motive power losses in traffic soon after their vehicle 'passed' the battery test. This 'solution' is causing a dangerous situation for the owners and the general motoring public. The Jeep has since been reevaluated and determined that the battery that the recall was intended to detect is indeed defective and is being replaced.

After taking my jeep 4xe in for the 95B recall I drove around 50 miles and the check engine light came on. Once home vehicle would not turn on or charge. Error on dash said -??charging system error.-?? Next day the vehicle would turn on be experience extreme slowness after stopping with bursts of acceleration. The accceleration and breaking system were extremely jerky and I felt like I didn-??t know how the car would respond when accelerating which was dangerous.

Metal chunks found in engine oil, and as were not metal powder swirl, shavings, or specs, possibly from bottom engine crankshaft. At the crank pulley, with the belt off, I could feel nudge by hand from the middle, for an engine component with max specified endplay 0.012 inches, or fraction of a millimeter. An existing manufacturer recall, and not a safety recall, for this 2021 Jeep Wrangler 2.0L Turbo is inspection for loose bolts for water pump inlet. This vehicle will not be available for inspection requests, because it is still not, and waiting to be, diagnosed as the dealer could not necessarily hear an engine issue. I have heard it knock, like a rumbling V8 and turbo whined, and recently I decided to strain the old and knocking oil that I kept and discovered metal. There was something wrong all along. Top engine, with good gas mileage, has been fine. The safety concern to this vehicle is metal in oil to possibly enter top engine and create sudden or instant engine seizure while in operation. The safety of driver or others could be at risk. The safety concern to this vehicle is also the detioration of engine components since they appear under the sole discretion of this motorized vehicle. This means, no other factor known to the driver of this vehicle by which rate of engine detioration has occurred. An indicating observation to be made into this vehicle's safety is the endplay of the crankshaft. This vehicle is nearly 97,000 miles odometer. The endplay seems very excessive, causing me to speculate on original factory fitment and installation during assembly. What determinations into a non-safety recall of loose water pump bolts might emerge as consideration into engine interior deterioration, as rate of this deterioration appear under sole vehicle discretion and remain unknown to the driver. Insufficient cooling is known to cause buildup in any engine, this vehicle has burped coolant air. No warning lights in the dash was seen.

After performing the 95B recall, within 20-30 miles of driving the CEL came on. After powering off and back on the -??service charging system-?? alert displayed on the dash. The vehicle seemed drivable however, and I proceeded to drive it to the dealership two days later which is about 4 miles away. In multiple instances when trying to accelerate from a stop the vehicle would not accelerate to more than 3-4 mph for multiple seconds leaving me stranded pulling out across traffic in the middle of an intersection waiting on the car to accelerate to a normal speed. Regardless of how much the accelerator was pressed the vehicle just rolled forward very, very slowly. Eventually, the vehicle lurched forward violently. Within this 3-4 mile drive this happened 3 times. The car remained jerky and unpredictable. I was fortunate to be driving at a low traffic time and made sure to allow extra space due to feeling the car acting slow after the CEL appeared. Had I treated it normally during normal commute hours, I would have been hit by oncoming traffic. I left the vehicle at the dealership and am waiting on response.

The vehicle-??s check engine light come on earlier this year and the electric motor/battery was not functioning properly. It was serviced in September and I was told by the dealership that the software update would resolve the issue. It did not. The vehicle was serviced again on 12/13/24 and I was told that it passed the 95B recall test but that the check engine light came back on. The dealership said they ran more tests and now the electric cooling/heating unit needs to be replaced but they won-??t have the part for approximately 2 weeks. The electric cooling/heating unit is for controlling climate within the vehicle and should not affect its propulsion. While driving the vehicle the day after I picked it up from the dealership, I was nearly involved in what would-??ve been a serious accident. I was turning at an intersection, but the vehicle lost motor function and would not accelerate, leaving me sitting in the intersection with traffic oncoming. Fortunately, after several seconds, the vehicle began to move with not much time to spare. This problem recurred throughout my drive returning home. I have not and will not drive the vehicle again until I am able to return to the dealership for a third time.

I was driving on the turnpike on or about December 15, 2024. I drove over some ridges on the Pa Turnpike. My jeep starting violently shaking out of control it felt like the wheels were gonna pop off. I had to grip onto the steering wheel to try to keep the vehicle from hitting any other cars. It went on for about five minutes then it stopped, but I could feel a change in the way, the steering felt. There was no warning signs on my dashboard.It felt like I didn-??t have complete control of the steering. After I got off of the turnpike, I was on 663 trying to get home safely after experiencing this terrifying experience. When i was on 663 I hit a red light and when the light turned green, I went to put my foot on the gas and it would not go so the person behind me almost hit. I had to put the jeep into park and I put it back into drive then proceeded to go and it was still driving like I didn-??t have complete control of the steering so then on December 19 2024. I set up an appointment with Sands Chrysler Jeep Dodge Ram. When I was on the phone With the advisor, she told me that was the death wobble that I was experiencing, but I need to have The Jeep diagnosed to verify that so I got a multi point inspection report Sent to me that said, Caution Steering Linkage (Damage/Leaks/Worn Components) Pending Recommendations Replace Steering Damper (Stabilizer) Associted Item General concern #1 customer states vehicle was shaking heavily on highway. The dealership is charging me when they know that Fiat Chrysler automobiles (FCA), The former parent company of Jeep issued a recall for the 2018 to 2019 Jeep, Wrangler and Jeep gladiator models due to a steering wheel vibration issue known as the -?? Death wobble-??. FCA recalled over 190,000 vehicles to replace the front suspension steering damper also known as the stabilizer. and that-??s Exactly what I needed to have replaced, steering damper Also known as stabilizer.

I have a 2021 Jeep Wrangler JL--VIN [XXX]. On Wednesday, [XXX], the vehicle suddenly and without prior warning overheated. I immediately parked the car. There were no obvious signs of leaks but we went and got some coolant and I put about 1/4 gallon of coolant in as it was low. I had the car towed to the dealership. The service advisor informed me that the issue was related to TSB 07-001-22 REV. B. They had to tighten the bolts connecting the inlet tube. As I searched on some Jeep Forums, I discovered that this issue was addressed with CSN ZD8, however, it's only applicable to certain VINs within 2021-2022. When I mentioned this to the advisor, she said my car wasn't affected by the recall. Clearly, this is a broader issue than just the VINs noted in the recall since this exact issue happened to my vehicle. I reached out to FCA and was assigned a case manager. After speaking with her, she informed me that she just talked with the dealership possibly providing cost assistance with the matter. I don't know why they're putting it back on the dealership when it's clearly a manufacturing defect. The dealership covered about 1/2 of the cost.

I was driving on [XXX] in San Diego going 75 mph and I received a number of alerts and flashing and audible sounds. When I looked at the dash it had an alert that said performance unstable pull over place vehicle in park. I immediately lost power to the accelerator and the car started to slow so I pulled over on the shoulder. Luckily, I was in the right hand side lane in the carpool section, and there was a shoulder. If there had been no shoulder, I would-??ve been stuck in traffic in the lane. The car would not restart and I had to have it towed from [XXX].

My 20214XE Hybrid from the day I bought it was often saying "electric not available" There was a potential fire recall last winter that took four months to remedy, during that time we were told not to charge it, park in our garage, park near our home/structures or park by other cars. I purchase a hybrid that I'm not able to use as a hybrid. Finally, got the repair in the spring. Literally, two months later, it starts doing all kinds of dangerous things. I would come to a stop or be in the middle of a turn and would have no power whatsoever, gas pedal to the floor and going nowhere and then would lunge forward. Took to the dealer, computer said CRITICAL hybrid battery overheating, the original repair clearly didn't work. Eventually, it was approved for hybrid battery being replaced. All was well until 2 weeks ago when it got "jeep death wobble", violently shaking back and forth at about 60mph. They did repair it but informed us that there is ANOTHER RISK FOR FIRE RECALL, do not charge it or park in garage, etc. etc. I have a vehicle that is a risk for BURNING MY HOUSE DOWN, this is multiple times and unacceptable. I also purchased a hybrid that I am not able to use as a hybrid.

I was leaving my home on July 25th. Suddenly when turning onto the freeway approach. The car battery light turned on. Then suddenly a Red Turtle came on dropping my speed instantly from 35 to 5 MPH. I was able to barely avoid an accident by throwing the steering wheel to the right moving out of traffic. Had this been about 1000 feet further along, things could have been dangerous. I had the car towed to the dealership.... where they informed me this is the hybrid battery.... an issue that I have had now 4 times with this vehicle and was supposed to be fixed. It has been in the shop for over 2 weeks.
