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.

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.

After charging my vehicle, I received a -??Service Charging System-?? followed by a check engine light. I tried to shift gears from P (parking) to R (reverse) and it wouldn-??t let me. When I finally got it to drive, my vehicle was only throwing hot air and it wouldn-??t accelerate. I was going about 20 miles per hour and it loss all the speed. When I got to the light and tried to accelerate again, it moved for like 10 seconds and I wasn-??t able to accelerate again leaving me stopped at the intersection for about 30 seconds. Once I was able to move again, my vehicle would stall.

July 2024 -?" driving over 40 mph the Rubicon on a busy two-lane highway with my [XXX] and lost all acceleration. Interior warning lights started flashing with the warning, -??Service Electric Throttle Control.-?? As this was up hill, there I nearly started going backwards and two vehicles swerved around me as I was able to pull over. As cars honked that drove by, I turned the vehicle off which was at this point, making a rattling/wobbling noise. I turned the vehicle back on and off at least three times, with hybrid vehicle working. As I was two miles from home, I was able to get back with the vehicle dropping acceleration (with no horsepower and no ability to go on gas mode) twice until I rolled back in basically neutral. We called USAA to have the vehicle immediately towed to Jeep Rairdon in Kirkland, WA. Jeep Rairdon said they would do an inspection three days later where they will assess if we can get a loaner. It-??s sitting in their service lot with no info. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my vehicle in four-wheel-drive low, with no lockers engaged I noticed that the rear wheels at different times were dragging, I could also hear and feel the ABS module actuating. During these events I would have diminished breaking capabilities and no ABS warning lights. it was doing it under 5 miles an hour at first and then higher speeds. I got a service ABS, service traction control, service stability control, four-wheel-drive unavailable, service four-wheel-drive system Messages all of a sudden, and i disengaged the four-wheel-drive lover back to 2 Wheel Drive. At this point the brake pedal was hard and would not move, my back left wheel was completely locked. I shut the vehicle down waited a few minutes and restarted it, all of the lights were still active but I was able to move the vehicle. I began traveling forward and the rear wheels alternated locking up. I started backing up to move to a safe position, the brake pedal became hard and I was unable to stop causing my vehicle to collide with a wall, speed was below 5 miles an hour but still caused damage to my left rear quarter panel and fiberglass top. After we assessed the damage, I put the vehicle in 2 Wheel Dr., disconnected the battery for 30 minutes, and was able to drive the vehicle to a parking lot in 2 Wheel Dr. After this point and not having phone service, use a satellite communicator to call a local off-road recovery nonprofit that I volunteer for, they were able to assist in bringing a trailer out to tow my vehicle home as it is unsafe to drive and my children were with me. Unloading the vehicle off the trailer all the lights were gone with the exception of a check engine light is now on. The vehicle is currently sitting in my driveway and will be requesting a tow to the local dealership for them to troubleshoot.

My 2021 Wrangler began experiencing a violent shaking and reduction of steering control in July 2023. The violent shaking would begin if my vehicle hit a bump while traveling at 65 mph or more. To regain control, I would have to brake and reduce speed to under 65mph (which also is extremely dangerous to do on a freeway). Thunder Jeep in Bartow, FL replaced a broken steering component that temporarily fixed the issue. The issue has now returned in late January 2024. I do not feel safe driving this vehicle.

When driving above 50mph, when I drive over a road seam, the car shakes almost uncontrollably. I have to slow down to make the car stop shaking. I have brought the car to Jeep service THREE TIMES in a period of 12 months. Still having the same issue. It is very dangerous. I cannot rely on this car (only 3 years old) to drive on a highway. Very dangerous!!

When coming to a stop and electric power is depleted, the vehicle will engage the gas engine and accelerate through a brake. I have to fight the vehicle to come to a complete stop because the engine is pulling me forward through the brake. Due to the unpredictability of the braking system, I must leave a greater stopping distance than required and have almost been in accidents. CAUSE UNKNOWN. I believe the powertrain, engine, and braking systems are involved. The vehicle has been inspected by the dealership shop several times for this problem, and one software update was offered to try to fix the issue, but the issue is ongoing. Yes, the vehicle is available for inspection upon request.

Same issue as the last time, and the time before that. Very dangerous, battery completely fails. The instrument meters are wrong and it shows that there is gas when there is really not any gas. Also more recently, we were driving on the highway in the express lane in the car just suddenly came to a stop. We could have died - luckily there was no one behind us. I managed to get the car over partially into the other lane so people could go around. The car had to be towed and I-??m done paying for this.

While turning at low speeds (pulling into a parking spot) and the cruise control is turned on the "set cruise" button is elevated and can be accidentally hit. If the speed of the vehicle is under 20mph it will automatically set the cruise speed to 20mph causing the vehicle to accelerate. This elevated "set cruise" button actives the regular cruise and not the adaptive cruise. This has happened to me over a dozen times. I am lucky it has not caused a wreck.

The incident occurred when I attempted to shift the transfer case into 4-Low. The sequence of events is as follows: 1. I stopped the vehicle and shifted into Park. 2. With my foot on the brake, I shifted into neutral and attempted to move the transfer case lever from 4-High, to 4-Low. 3. As I started to move the transfer case lever, a warning appeared in the instrument cluster stating, "Vehicle speed too high to shift". 4. Auto-Park engaged 5. The engine, uncommanded, with my foot still on the brake, began to increase in revs slowly. 6. Check engine light illuminated, the engine continues to increase in revs. 7. When the engine reached 6-7k RPM, I hit the engine start/stop button and held it down until the engine turned off. The engine was still climbing in revs until this point. 8. I restarted the engine and could shift into 4-Low successfully. "Off-road cruise control disabled" warning light illuminated and remained on until I shifted back into 4-High. Check engine light remains on after multiple starts.

Vehicle loses power without warning. This has occurred numerous times, twice on a crowded freeway when I had to navigate across 5 lanes of traffic. Dealer was unable to isolate and repair the problem the first time. Vehicle is in for repair again. An internet search indicates this is not uncommon and at least two class action suits are pending. I'm shocked this life threatening fault has not already been reported to the NHTSA. Repair codes are : P1E1D control module improper wake up performance, U1817 Lost communication with hybrid powertrain control module on D-PT, U0293 confirmed, lost communication with hybrid control module.
