2020 Jeep Gladiator Fuel system Problems

The digital instrument cluster in my 2020 Jeep Gladiator has failed. The center display (LCD) went completely black, even though the backlight still glows faintly. This screen typically displays critical information such as vehicle speed, warnings, messages, and alerts. Without this display, I cannot monitor key safety information while driving. The analog gauges still function, but the central digital panel remains blank regardless of ignition mode (RUN or ON). After diagnosing the issue myself, I confirmed power was present at the fuse terminals. I inspected and replaced fuse F36, which was damaged and likely contributed to the display losing power or shorting. I also inspected related fuses F43 and F57 (BCM and IOD power supply), which were intact. This is not an isolated problem. Research shows that other Jeep Gladiator owners (especially 2020 models) are experiencing identical symptoms — black instrument displays, “Push Brake to Start” messages that stay on after shutdown, and modules not entering proper sleep mode. These issues align with the symptoms listed in TSB 08-002-21A, which relates to software and communication faults between the BCM and IPC. Jeep dealership confirmed the failure and quoted $700–$1,000 for full cluster replacement, stating there are no DTC codes and no reflash updates available, and that the cluster must be replaced outright. Jeep has not issued a recall, yet this is clearly a widespread failure affecting visibility and safety of vehicle operation. The problem poses a safety risk to myself and others. I cannot see alerts or diagnostic messages while driving. If this happened at night or during highway travel, it could increase accident risk. Jeep should issue a recall or warranty coverage extension for the instrument cluster failure in affected 2020 Gladiators.

The digital instrument cluster on my 2020 Jeep Gladiator has been completely nonfunctional since late November 2024. This failure means I cannot see the odometer, digital speedometer, and all other vehicle status indicators displayed through the cluster. The problem has been confirmed by an authorized Jeep dealership, which has been unable to secure a replacement part due to a reported supply shortage. Jeep corporate has had this case escalated for months without resolution. As a result, I have been driving without these essential instruments for over 8 months, with no timeline provided and no workaround. In addition to the loss of fuel and mileage visibility (and potentially odometer functionality), I also cannot confirm whether the cruise control is active. This could cause potential safety risks during highway travel. There were no warning lights or error messages prior to the failure. The cluster simply went dark. The faulty component is still in the vehicle and available for inspection. Jeep is aware of the issue, and a case is currently open.

Began driving vehicle on short 4.5 mile trip to the store with over 1/4 tank of fuel. Began to smell of fuel inside and noticed that when accelerating from a stop vehicle would hesitate and stutter. Halfway through trip noticed that vehicle had only 1/8 tank of fuel left and light came on. Pulled into parking lot at destination, shut vehicle off near empty and noticed trail of gasoline behind vehicle and pooling fuel below. Observed underneath that fuel had been spraying at a high pressure from the top of the fuel tank ( exact source not visible) all over the underside and all over the exhaust system, pooling in the skid plates and all cavities underneath. Vehicle would not restart for tow operator.

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.

I have had this vehicle in the shop more times than it has been on the road. It originally started with the auto start stop sensor. They told me to turn that off. They did an update. And it kept happening over and over again where it would cut itself off and I couldn’t get it restarted. The fix worked for maybe a month and it started all over again. Now the engine light is on I can be doing 30 miles an hour down the middle of town and it dies even with the auto start stop turned off. The steering is so loose that you have to fight it all the time to keep it in the road. The engine light is on and stays on. And it sounds like a scraping when the vehicle is in motion but the tires have clearance and no issues with their clearance. Checked under the vehicle nothing is under the vehicle. This vehicle has never been off road. I believe it qualifies as a lemon.

Truck had very low power from day 1. Start/stop functionality mpcb short. Engine shacking and making noises. Engine burns oil. Trucks fuel economy is worse then a v12!I was getting 14 miles per gallon. The steering sucks it tilts to the right. Truck feels very unsafe to steer. The steering radius on ir is terrible. Trucks engine temperature goes up when is idling. Starter was staying on and hard to start. Engine would stall crossing the street. Engine stalled in the highway going 65 mph.it generated 10 check engine codes.the chassis of the truck is not completely welded trough. There is gaps all over it.over all the truck flimsy and unstable. The 4x4 was making noises. My oil would get black after 3k miles of driving it.If I was to leave truck on for it to get warm or cold any body could jump in and steal it, even if I have the keys. Truck started having issues at 7 k miles Ac didn’t blow very cold air. Hot air from outside will come in the pit. At last truck broke down it stalled in the middle of a intersection, or would not no into neutral to push it out of the road. I was trying to start it but the stater was very sluggish and after 3 times of me pushing on the start button it started smoking, when I saw this I panicked and trying to make it stop from starting but the starter kept going and going until it kept smoking after 5 minutes it stoped, I open the hood and it smelled like a electrical fire, I was going to call the fire department but it ceased smoking, so I stopped and somehow got it to a safe place. Truck didn’t want to start ever since. I never did any upgrades so that I would not void my warranty, I always did my oil changes and did my tire rotations. Never overloaded my truck or took it off-road. I never put a big trailer on it.I always washed it and took the best care of it as possible.mind you this all happened at 34 thousand miles and I am under new car warranty, even after all this I would still buy another Jeep gladiator
