2020 Jeep Gladiator

My entire Electrical system failed, the engine wouldnt start , the warning flashers would not work, the vehicle wouldnt go into neutral to be pushed. So I was blocking an intersection for about 2 hrs waiting on a tow truck to tow it to the nearest dealership. The dealership was unable to reproduce the problem just wants to replace the end result of a 150 amp fuse block blown at $400 for a $50 part. I attached what was actually going on with the vehicle in PDF format I researched on Gladiator forum and Jeep Garage forums and found this is a problem for many jeep models with the dual battery system but nobody had an answer as to why it happens other than something shorted out.

I have had my vehicle in for the same problem at least 6 times, since August of 2022. The battery keeps dying. This is a know problem with this model. If it is not started for more than one day it will not start. The dealerships have replaced the batteries, main and auxiliary, multiple times, they have replaced the cable and wires, connectors and alternator. It still happens and no aftermarket parts have been installed related to the electrical system. I am missing two of the receipts to upload at the moment.

Delivered to Jeep Dealer, Hetrick Jeep Dodge, Elton, MD. by tow truck.

While I was driving on the freeway, suddenly all of my warning lights came on and my windshield wipers and the power steering went out. It was very difficult to pull over with the power steering out and stop. This is the second time this has occurred in 6 months. The first time this happened I had it towed to the dealer, they found nothing wrong but when I went to pick it up it happened again before I left the dealer. The service manager kept it and they ran more codes and thought they resolved the problem, but the same thing happened again when I went to pick it up. Finally, they gave me a loaner vehicle and after a month the Gladiator was finally fixed. The dealer said it was a defective wiring harness. Now the same problem is back. This is a serious safety issue due to the power steering going put and locking up the steering wheel. I have read many, many complaints from other Jeep Gladiator owners of the same issue.

While driving on a main road, in a rural area, the "Electronic Stability Control Maintenance" alert was enabled. It was a cold January morning and approximately 35 degrees at 9am. My tire pressure alerts were also activated and I presumed that the Stability Control alert was due to a potential flat tire, not just a cold morning pressure imbalance, which happens frequently when there are drastic swings in temperature. Less than a minute later, the "Electronic Throttle Control Maintenance Required" alert flashed and I lost the ability to accelerate. I was in an area that was going uphill and no shoulder. Due to my momentum, I was able to get halfway up the hill and pull over into a residential driveway. I shut the car off, waited a minute and turned it back on. I attempted to pull back onto the road and noticed that a) I could still not accelerate and b) There was a large oil truck barreling up the hill and I would be a potential hazard and accident if I pulled in front of it. I then began to notice that smoke was billowing from under the hood. I turned back into the residential driveway and immediately shut off the vehicle and called for roadside assistance. The vehicle was taken by flatbed to the nearest dealership to be diagnosed. They ended up determining that there was moisture in the oil and claimed that it was common in this model year. They flushed the systems and gave me an oil change, which was was due for anyhow. The dealership kept the vehicle overnight and said they wanted to assess how it would perform in cold temperatures before returning my vehicle. I am very concerned that this is happening so soon. It is the first new vehicle I have ever purchased for myself and I do not take it off-road and live 10 miles from work, travelling on rural roads and recreational highway travel three-four times a year.

The ESS/Auto Start/Stop system is unavailable rendering the remote start for cold weather unavailable. This issue also effects the reliability of the battery and electrical supply as a whole potentially leading to unexpected engine stoppages and stranding due to a no start scenario. The issue is widespread and well documented among 2018-Current Jeep Rangler models as well as 2020-Current Jeep Gladiator models. Causes are reported by dealers ranging from premature failure of the start/stop auxiliary battery to TPM/distribution box failures. My vehicle has experienced this issue twice with the first occurrence shortly after purchase. With many of the effected vehicles reaching the end of their warranty period, the number of vehicles circulating on highways will increase creating a safety hazard. Further, the failure of this system may create an EPA compliance issue as the ESS/Auto Start/Stop system is required equipment to meet EPA fuel economy standards for the fleet.

I recently purchased this vehicle used, while driving the lights go off and the vehicle shuts off while moving. Not displaying any warning indicators at the time. Luckily vehicle is a manual, so I have been able to coast to a stop safely. Situation could be very dangerous. Once off the vehicle will go dead and won't restart. After a few moments vehicle will restart until the problem occurs again without warning. Jeep/chrysler has obvious issues with this vehicle and has not done any recalls. Even though they have documented occurrences with similar vehicles.

Jeep turns off/power off/ dies when driving any speed. I was driving in freeway 60+mph and it just died. I took to dealer on january 2022 and took 2 weeks to figure out a electrical  wiring  hardness was bad. It was good until now October 2022. It died again like the first time. Only way to power it up is getting a battery jump. This is same issue as the first time. It was not cheap and I seen online that alot of other gladiators are having same issue.im about to take it again to dealer this week

I have been having problems with my steering 17 thousand miles after I bought this 56k dollar jeep. sometimes the steering wheel locks to the left or to the right when pulling out of parking lots.than it also pulls to the left in the high way. My motor mounts also are not good any more because they make noise and my motor rocks back and forth.The shock absorbers all 4 also need replacement. This jeep is steering and handling is very unstable and I don’t feel safe driving it. My starter needs replacement for the 3rd time. my gas consumption is 10 miles to the gallon!!!!my day running lights don’t turn on and this issue with lights and electrical problems been with this jeep since 7k miles after I bought! If you leave this jeep on you can take the keys with you it some one can just drive off no keys necessary. my speakers are sounding scratchy for a long time and no repairs to this yet. 35k miles driven, my jeep has been at the dealership for several times getting all kinds of repairs.
