My front suspension keeps bottoming out while driving down the road. If I catch a pothole or dip in the road I will bottom out. Today I was in a parking lot and it bottomed out going over a speed bump. I know there is a TSB for the eco diesel Rubicons but for no other sub-models.

I was driving the vehicle, while towing a 5000lb trailer (vehicle tow rating is 6000lb), up a 4-5% grade at 4000'-6000' elevation, with ambient temperature around 80 degrees, and the vehicle unexpectedly derated / limited speed to approx 45 mph with no warning indicators on the vehicle. I had a number of cars and semi trucks behind me, and so I unexpectedly needed to find a safe place to pull over, which was limited due to the road conditions. I travel in areas frequented by semi trucks with limited shoulders. If I had not found a pull-out, this could have been dangerous. This appears to be an issue countered by a number of Jeep Gladiator Diesel owners, relating to either engine oil temperature too high, or EGT temp too high when towing uphill.

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.

After stopping for fuel in Quartzite, Arizona I began to merge onto HWY 10. As I accelerated the vehicle limited my speed to 45 MPH. This is on a 70 MPH section with heavy truck traffic. I was able to pull onto the shoulder and limp to the next exit without incident. I then drove around backroads for 10 minutes, starting and stopping the vehicle and accelerating to 55 MPH. After this period of time the vehicle operated normally. This happened with no warning at all, temperatures were all within normal ranges. Since the incident I have found that this "derating" is common to the diesel engine in hot ambient temperatures or while going up hill. My safety was definitely at risk, in a different scenario it could have been much worse. I have spoked with several factory service centers and Jeep directly, they say they have never heard of the issue and don't have any advice.

3.0 EcoDiesel in the Jeep Gladiator has cooling issues. Thousands of users affected and discussing on forums and on Facebook groups but the manufacturer is unwilling to fix. Core of the issue is that the engine was altered in the Gladiator and Wrangler over previous installations in the Ram and Grand Cherokee by removing oil coolers and a larger oil pan, which has resulted in high oil temps. At 265 degrees (which is accomplished easily during the summer with a trailer UNDER the tow rating), the engine starts derating and limp mode. The aftermarket community has tested everything ... removing hoods, fenders different cooling solutions, etc and nothing is working at the moment other than aftermarket solutions to cool the oil (which are negligible at best at the moment due to the space constraints imposed by the engine being quite large in the engine bay not not substantial room for a larger oil pan and external cooler). Chrysler should have put more work in to the design, or not sold the EcoDiesel in the vehicle.

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.

PE24024 · Underhood Fires

Opened Sep 6, 2024 · No close date supplied

Status: open (inferred from source dates) · Steering:hydraulic Power Assist:pump

The Office of Defects Investigation (ODI) has received 9 Vehicle Owner's Questionnaire (VOQ) reports, 1 Death and Injury report, and multiple field reports alleging incidents of engine compartment fires in model year (MY) 2021-2023 Jeep Wrangler and Gladiator vehicles. The majority of the reports describe a fire occurring while the ignition in the vehicle was in an ‘OFF’ state with a suspected origin at the passenger front side of the engine compartment. An ignition ‘OFF’ vehicle fire can result in an increased risk of occupant injury, injury to persons outside the vehicle, and property damage, with little to no warning. ODI has contacted the vehicle manufacturer, Fiat Chrysler Automobiles (FCA), and learned of several thermal events originating at the power steering pump electrical connector in recent model year Jeep Wrangler and Gladiator vehicles. The location of the pump connector is located at the passenger front side of the engine compartment, coinciding with the majority of fire reports known to ODI. ODI is opening this Preliminary Evaluation (PE) to assess the cause, scope, and frequency of the alleged defect. To review the ODI reports cited in the Opening Resume ODI Report Identification Numbers document, go to NHTSA.gov.

EA23001 · High Pressure Fuel Pump Failure

Opened Mar 17, 2023 · No close date supplied

Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337
