2021 Jeep Gladiator fuel system problems

FUEL/PROPULSION SYSTEM

Truck failed to find gear shuddered lost speed in traffic while going up a hill. Limp mode was initiated. This is a known manufacturers defect with a tsb applied against the known issue. Issue is widespread when researched but not made known by the manufacturer of the truck. Dealership refusing repair under goodwill due to truck being out of mileage by 5000miles. Symptoms started prior to exiting warranty but due to no communication by dealership or manufacturer unit was not brought in for repair prior. Repeat this is a known defect that is being ignored by manufacturer.

FUEL/PROPULSION SYSTEM

The vehicle was bought in CA and hasn't had any issues till about after 3-4 yrs later. 1) Adaptive cruise control / emergency braking system / forward collision notification will occassionally state "not availble/unavailable" or "visibility" is not available and to clean windshield, but the windshield is not dirty or obstructing the camera. 2) The fuel emission system has had several diagnostic codes referring to the gas gap or fuel sensors. Vehicle is boggs down/loses power and starts ideling roughly and acts like it wants to shutdown and has shutdown. I've had to get vehicle towed twice for this issue. Replaced gas gap and still had issues. Then they went away for a few months, but now I am getting a diagnotic code stating that the fuel tank gas sensor is causing the check engine light.

FUEL/PROPULSION SYSTEM

7/5/2026. Driving home on the highway the Jeep went into limp mode and shut down. The Fault flashed on the screen for about 15 seconds (Throttle Body Falut) Problem is there is no warning when it happens. It just shuts down. This creates a "REALLY SERIOUS HAZZARD" This time it did register a fault on the computer and we were able to pull it off the reader. The Fault reads as follows: POOAF In looking it up on this is a manufacuring problem that can be caused by a little dirt, Can be caused by hot weather. THIS IS NOT SAFE! MY I REPEAT, THIS IS NOT SAFE! This should be recalled and Fixed as I am sure this shutting down on the Hiways and Interstates have killed people that were not able to deal with a situation. Please force a recall befor lives are lost!

FUEL/PROPULSION SYSTEM

Bought this vehicle with 27,000 miles on it. While driving on the interstate with heavy traffic. (Doing Highway speeds) All the sudden the power plant shuts down. It happend at 27,500 miles and happened again at 37,000 miles. It has done it to me four times now. Twice with heavy semi trucks bearing down on me and my family. This was a very UNSAFE situation. The Fault on the screen comes up momentarily and states "Capture Throttle Body Fault." and all power is lost to the throttle. SERIOUS SAFTETY ISSUE. as loosing power on the interstate at 75 miles an hour. I believe JEEP the company should fix this issue as I know for a fact I am not the only individual experincing this problem! Please feel free to reach out to me if you need further information. There was not a crash,fire or injury due to the ability to get off the road and into the apron of the interstate. In a higher traffic location this could be catistrophic. PLEASE PLEASE PLEASE talk this issue seriously as I am convinced this has caused others to wreak. Thanks and have a great day

FUEL/PROPULSION SYSTEM

Mopar recall Z96 posted October, 13th 2022 for high pressure fuel pump. My local dealership stated parts for replacement of the high pressure fuel pump did not become available until November of 2023. They inspected my vehicle November 21st, 2023 and determined the high pressure fuel pump was to be replaced under mopar recall Z96. Dealership ordered parts at that time. On to March 4th, 2024. I reach out to local dealerships service and parts departments. Not all parts had been received and there was no understanding of when the rest of the necessary parts would arrive. May 7th, 2024. It is now nearly 1 year and 7 months since this recall was released and nearing 6 months since my local dealership stated they ordered parts to replace the fuel pump. My local dealership continues to have no understanding or intention of securing the remaining parts necessary to complete this recall. This amount of time is unreasonable for a part that if it fails will cause loss of engine power and may cause a fatal crash.

FUEL/PROPULSION SYSTEM

Vehicle derates power when ambient temps are 85* F and up while towing my camp (which is far below the max tow rating) During a couple of these derates I was in areas where the speed limit was 65 and 75 mph, my max obtainable speed was 35mph. I heavy truck traffic i feel that was in danger and a hazard in the road. This vehicle is rated to tow far more than the loads it is actually capable of towing in higher temperatures. I have seen my oil temps rise to 265* F on multiple occasions and it seems this is around the temperature that the vehicle starts to derate. It has been my observation that the cooling system is under sized and in turn puts occupants of the vehicle at risk.

FUEL/PROPULSION SYSTEM

When operating the vehicle under heavier loads (5%+ grades, towing even light trailers, higher highway speeds) vehicle loses power limiting speed to 15-50mph depending on how hot the water or oil temperature is. I have had this issue in ambient temperatures as low as 31°F while towing 4000lb up a steep incline, but will absolutely overheat if ambient temp is over 100°F. Vehicle must be left running during a fuel stop or heat soak caused by the vehicle is not running will prevent me from merging back on the highway at a safe speed....max speed is 50mph until the engine oil cools off. Air conditioner use as expected makes the problem worse. There are many threads going on the Jeep internet forums with many diesel equipped Jeep Wranglers and Gladiators having the same issues, so I know these aren't isolated incidents from my vehicle alone. If you were to search "Ecodiesel power derating as temps rise" on Google, you would see some discussion. Engine fan runs at full speed, coolant is full, and radiator/grill is clean/free of debris. I have owned this vehicle since new and have operated in many types of conditions/loads over the past 14 months 23,000 miles from 9°-126°F. The first time I had the issue was late May of 2021 (At approx 5,000 miles) and it has happened no less than 20 times since then. The only visual alarm is when coolant temp reaches 248° and the vehicle speed drops to 10mph. The gauge does not read linear........Meaning the vehicle is almost already overheated by the gauge shows the temp is rising. I can only assume the is intentionally programmed into the code by the vehicle manufacturer to make the operator feel like the high temps are normal. I have not had the vehicle inspected by the local dealer because in the past they were never able to duplicate the conditions in my opinion due to laziness or incompetence. I own an auto repair shop and know the problem to be an undersized cooling system which Chrysler does not have an approved fix for.

FUEL/PROPULSION SYSTEM

The vehicle randomly stalled out / died while idling, with the clutch pedal fully engaged. This poses a serious safety hazard as the vehicle may unexpected stall out at a traffic light or while driving resulting in a serious accident. The most likely risk is a stalled out vehicle in heavy traffic resulting in a rear end collision. The vehicle stall out and failure to maintain idle malfunction was reported to the local dealership and an FCA Technical Advisor (TA). The vehicle’s stall out was witnessed and documented by an independent mechanic. However, the dealership and FCA TA continue to state that the vehicle is “operating as designed” and that “this is normal characteristic of the vehicle”. These claims indicate that the Jeep Gladiator Engineering Design Team intentionally designed the vehicle to stall out with the driver completely pressing in the clutch pedal. The vehicle is available for inspection upon request.

NHTSA complaint #11447462 — an unverified report by a vehicle owner.

FUEL/PROPULSION SYSTEM

The vehicle’s throttle bounces and surges off idle, in direct opposition to the driver’s inputs to the controls. After the driver lifts off the accelerator and engages the clutch, the RPMs drop slowly to idle, then the throttle regularly bounces and surges without user input to the controls by ~500 to ~1,500 RPMs. The issue occurs while driving in every gear and or in neutral. The issue occurs frequently but not every time. The issue occurs with or without the driver’s foot on the brake. The failure to maintain idle malfunction was reproduced and confirmed by multiple service personnel at the local dealership. However, the Service Director falsified and backdated the service records to claim that they “couldn’t duplicate concern” and that the “vehicle is driving normal.” The throttle spike off idle was recreated by 4 independent mechanic shops and documented as a safety concern. An FCA TA claimed that the vehicle was “operating as designed“ both when he could not recreate the issue and when he could recreate the issue. Both of these statements cannot be correct and factual as they directly contradict each other. The throttle bounce and spike off idle substantially impairs the vehicle’s use as it impacts normal driving operations such as shifting, accelerating, and braking. The throttle bounce off idle creates as serious safety hazard as it causes the driver to delay or miss shifts in heavy traffic and divert attention from the road to the instrument cluster. The issue also creates a serious safety hazard as it induces driver confusion by making them think they accidentally pressed the accelerator while shifting. The claims of “operating as designed” indicates that the Jeep Gladiator Engineering Design Team designed a vehicle to spike the throttle without driver inputs to the controls. The vehicle is available for inspection upon request.

FUEL/PROPULSION SYSTEM

The vehicle’s throttle surges sporadically when shifting gears without driver input to the accelerator / controls. The issue impacts the driver’s ability to operate the vehicle safely in heavy traffic or dynamic situations. The throttle surges while shifting introduce delays to driver reaction times, and they create a safety hazard in heavy traffic where fractions of a second can make the difference in a major accident. The throttle surge while shifting malfunction was reproduced and confirmed by multiple service personnel at the local dealership. However, the Service Director falsified and backdated the service records to claim that they “couldn’t duplicate concern” and that the “vehicle is driving normal.” The throttle surge while shifting was recreated by 4 independent mechanic shops and documented as a safety concern. An FCA Technical Advisor (TA) claimed that the vehicle was “operating as designed“ both when he could not recreate the issue and when he could recreate the issue. Both of these statements cannot be correct and factual as they directly contradict each other. Additionally, the FCA TA claimed that the vehicle is equipped with Rev Matching; however, the vehicle’s owner’s manual and available technical documentation do not mention Rev Matching. And, the issue occurs while braking when a vehicle would not intend to Rev Match. The randomness of this throttle surge issue also causes the driver to briefly take their eyes off the road between every shift to check the tachometer for the throttle surge malfunction. Distractions like this which divert the driver’s attention during what should be routine driving tasks, creating a safety hazard. To account for the unexpected throttle spike, the driver must deviate from a normal driving routine by taking extra steps and inducing significant delays in response times. I feel unsafe driving the vehicle. The vehicle is available for inspection upon request.

FUEL/PROPULSION SYSTEM

The vehicle auto stops when the hood is closed and the driver remains in the seat with the seat belt buckled. The owner’s manual specifies that an open hood will prevent an auto stop, but preventing the auto stop is the opposite of closing the hood initiating the event. Furthermore, the instrument cluster never presents a “STOP/START READY” message which is the first necessary condition for an auto stop. This issue creates a serious safety hazard, as the vehicle presents incorrect information to the driver and the vehicle unexpectedly stops which confuses and distracts the driver. Additionally, after jump starting another vehicle, the vehicle’s battery may be sufficiently depleted. Upon closing the hood, the vehicle could auto stop, and with the numerous other malfunctions impacting the auto stop system the vehicle may not be able to restart possibly leaving the driver stranded. The unexpected / wanted auto stop could cause a rear-end collision of the stranded vehicle leading to serious injury or death. The malfunction was reproduced and confirmed by multiple service personnel, who expressed safety concerns. The malfunction was also recreated by 4 independent mechanic shops and documented as a safety concern. However, an FCA Technical Advisor (TA) claimed that the vehicle is “operating as designed“. This portion of the vehicle’s Auto Start / Stop System is NOT operating as designed and documented in the owner’s manual. I feel unsafe driving the vehicle, as this is one of numerous hardware / software malfunctions plaguing the vehicle. The vehicle is available for inspection upon request.

The vehicle auto stops when the steering wheel is turned, in direct conflict with owner’s manual. The owner’s manual specifies that “Steering angle beyond threshold” will prevent an auto stop, but preventing the auto stop is the opposite of initiating the event. Furthermore, the instrument cluster never presents a “STOP/START READY” message which is the first necessary condition for an auto stop. This issue creates a serious safety hazard, as the vehicle presents incorrect information to the driver and the vehicle unexpectedly stops in traffic which confuses and distracts the driver.
