My Jeep has the 3.0 ecodiesel engine and there are two batteries. One battery is huge and powers all the components on my vehicle. The second battery is tiny and considered an auxiliary battery. It is located in a place that I can not get too, and can not check to see if its good or bad. However, as soon as it has any issues it will keep the Jeep from starting up. If you are out in the country or in the middle of nowhere then you will be stranded. It does not matter if the larger battery is working perfectly, the auxiliary battery will disable the entire vehicle anyway. This is a huge safety issue for obvious reasons. According to Jeep forums over the internet, this is a very common issue on all Jeeps with two batteries. It would be nice to take the auxiliary battery out, but Jeep engineered the two batteries to disable the entire vehicle if the auxiliary battery dies. Poor engineering? Perhaps! I would suggest there be a recall and that Jeep be forced to take the auxiliary battery out and re-wire the electrical system to allow vehicles to start regardless of the auxiliary battery. Some customers might want to keep the auxiliary battery cause it plays a part with the auto-start system. I would like to remove the battery and the auto-start all together and still have a functioning vehicle. I don't want to be stranded out in the middle of nowhere where I have no cellphone service.

My 2021 4XE Wrangler Rubicon has already had the Loss of Motive Power Recall performed a year ago. Jeep stated that the recall software update would prevent this incident. It is not corrected!!! Yesterday, while traveling on I-70 near Virginia at about 70 mph (the speed limit), the Jeep displayed a Jeep Vehicle with the PHEV High Voltage Cables and Battery Pack Diagram drawn over the Jeep in Bright Red color. No codes happened at all when this appeared (no Check Engine Light, no service indicators, nothing). Some words quickly flashed on the dash display stating something like, "Loss of Performance" and the engine shutdown completely and the "D" next to shifter binked yellow continuously afterwards. The dash then stated to Shift Vehicle into Park to Restart (while still coasting at nearly 70 mph). I managed to coast it to the emergency lane, stop the Jeep, shift into park and restart. It then would not run even remotely normal, because it was in a safety mode of some sort. Again, with the engine running completely erratically, no coding at all. When I pressed the accelerator like normal, it would not respond at all (even putting it to the floor had no affect). I had to figure out how to get the accelerator to work so I could drive it back home. I had to gently press the pedal to get it to respond and then the Jeep would not go above about 2500 RPM. It would force itself to slow down if it reached any higher RPM. I went to the local Jeep Dealership ASAP today and was told nothing was recorded in the computer, software is up to date, and there is nothing wrong with my Jeep. This is a serious problem and has to be diagnosed and fixed!!!!

The sensor witch detects if the front and rear differential lockers is engaged or not has quit working. Once I looked into it, the sensor was full of diff oil causing it to stop working. I then found out it has been such a big issue that Jeep has a National back order on the part to replace it. The parts were found to be leaking in almost all Jeeps tested. That component is a major part to the off-road capability. I found myself in the back of my local national forest and unable to get unstuck because I drove through mud that would have been no problem if my lockers work functioning properly. If it weren-??t for me owning an emergency satellite transponder I honestly don-??t know how myself and my twelve year old would have made it out. I live in the middle of grizzly bears. Spoke to Jeep and was told -??they know it-??s a major issue but won-??t fix them until told to do so-??

On 9/16 I went to leave for work for the day and my car would not start. The auto stop start system was illuminated with a warning. A neighbor jumstarted to car for me. I drove to my dealership where I was told both of my batteries had failed and I would need to replace them. I replaced both. Upon leaving the dealership my stop start was still showing a warning. I was told it would go off after driving for a few days. It did not. I returned to the dealership on 9/25 to see what was wrong. The code the vechicle was giving was low battery. I was told it was a software update and was sent on my way. This issue with my vechicle par of a RRT21-077 dated 6/24/21. I was never notified of this by Jeep. I was told when I brought this to their attention that because this probelem did not occur within 18 months of the bulletin my issue would not be covered. I am concerned that this issue will happen again and leave me stranded without power, as clearly it is an issue with this model.

I-??m reaching out due to a severe issue with my Wrangler 4xe Rubicon that has left me stranded twice in 2 weeks. The vehicle is shutting down, without warning, and is not able to re-start, so you can just imagine that the circumstances could be far more dire or outright life-threatening had this happened in a remote location or a dangerous high-traffic area. Both times the vehicle had to be towed to the dealership. Even more troubling is that the root cause of the malfunction (OBD CODE: P0BBD HYBRID BATTERY VOLTAGE VARIATION EXCEEDED LIMIT) has yet to be diagnosed, despite the vehicle being serviced for the better part of a week, only to suddenly refuse to start just 3 days after getting it back -?" again, leaving me stranded. Multiple attempts to reach Jeep executives over several days has yielded no response. All my safety recalls have been addressed so Jeep has told me this vehicle was safe to drive before these incidents. Additionally, the vehicle was in the shop for the better part of 2 weeks earlier this year with a battery heater malfunction. I work in emergency surgery and if I don't have a reliable vehicle to respond to emergencies, patients can literally die. That is not hyperbole, its reality.

While driving the "Service Shifter" warning appeared in the center cluster notification area repeatedly. There was reduced vehicle performance and a continuous chime alert from the vehicle. Turned the vehicle off, waited several minutes and then turned the vehicle back on and the "Service Shifter" warning appeared again with the continuous chime audio alert.

My car was called in for a recall. The dealership stated they don-??t have the correct software to update the issue but said to come back when they do. They never fixed my vehicle and now it-??s howling my recall was fixed. But my car is still having the electrical issue and it almost shut off on the freeway.

My rear locker is trying to lock while driving in 2H causing the light to flash constantly. Now due to that occurring the service locker is on this is a known issue and needs to become a recall as most Jeep Wranglers and Gladiators have this same issue

I went to the dealership. They said since there were no lights or messages on dashboard they really couldn-??t do anything. I insisted on them looking at it and they scheduled an appointment a week later. They said I have to leave the car with them for a week so they can look at it. They won-??t give me a loaner to drive and they are short staffed so the car just sits on their lot for a week. This is completely unacceptable. There was no sense of urgency on something that could-??ve turned into a tragic accident driving on the highway in Chicago. I took the car home. It was driving ok this week until today Saturday 8/27, my appointment is for Monday and car is completely dead and won-??t start.

When I was driving normally the service shifter, service electronic stability control, auto park disabled error message displayed. Also the traction control light, parking brake light and the cargo light all turned on. Then lost power steering, at full speed. Tried to safely pull off the road. Coasted to a stop, where I then lost all power to the vehicle. Was unable to restart. Had it towed to Jeep dealership, for further inspection. The third time for the same issue. With no resolution or repairs. As they say, they can not reproduce the catastrophic failure. It has not been inspected by the manufacturer. It happened so suddenly I barely had time to pull over. If I was driving in the middle lane or on highways. I would have lost power steering, and stopped in the middle of the road. At higher rates of speed or other circumstances. It could have caused serious injuries, or even deaths. I am no longer comfortable driving this vehicle. For risk of personal injury or death, and being a danger to other drivers on the road.

Earlier this year vehicle would sometimes do the following, not at start up but when driving; Wipers on by themselves & driver can't shut off, turn signals inop, Both sides blind spot warning continously on alerting driver every time a vehicle on either side is passed or passes vehicle, anywhere from three to five dash warning lights illuminated. Took to dealer in April 2023 & diagnosed a bad can bus connector. Replaced connector (approx $700). Seemed to be the fix until it started again June 2023. This time all the above issues started up again including loss of power steering. I was on I70 at highway speeds in rush hour traffic and it was very dangerous. Returned to dealer yesterday 6/29/23 Immediately following loss of power steering while vehicle was displaying faults & they read codes. They are booked for 2 weeks so I'm scheduled to drop it off 7/10/2023. Dealer has been fine to work with and willing to help. My chief complaint is I have found numerous others that this is happening to (internet Wrangler JL forum) & I feel like car mfg knows about this and is not doing anything about it.

Vehicle will stop working in electrical mode...says "electrical mode unavailable" Dealership does NOTHING, vehicle performance is unpredictable. Sometimes will not start without a jump when the battery is fully charged from a 220 outlet. I've had it towed as I was stranded... dealership said "nothing wrong" ZERO diagnostic test to see if battery has a bad cell. Yet less than 24 hours from picking up at dealership, will only operate in gas mode. NOW it seems to down shift when I take my foot off gas....makes a grinding sound. Appears I purchased a lemon.

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.

My Jeep was brought to Carl Burger Jeep because the check engine light stays on all the time. The dealership performed several software updates. The Check Engine light still stays on and has been on every since. About two months now. It was discovered that there is a part required for the EV battery that is not available due to back order. The service dept. said it was safe to drive. How do they know that? There has been a case opened up and a person assigned to my case. Who knows what that means. All I know is I'm very uncomfortable driving around with the Check Engine light on 100% of the time, especially with the size of that battery sitting right in back of me. I was told by the service dept. that they do not have an ETA for the back-ordered part. Nor have I received any updates on Please give me your recommendation on what to do.
