While driving on the highway, the check engine light illuminated. Approximately 5 to 10 minutes later, the battery warning light came on. Upon exiting the highway and coming to a stop at an intersection, the automatic engine Start/Stop system engaged and shut down the engine. When attempting to safely proceed, the vehicle suffered a complete electrical failure due to the 48V mild-hybrid eTorque system failing to restart the engine. The vehicle refused to crank, would not shift, and became entirely disabled and stranded in the middle of a live intersection, creating an extreme safety and collision hazard. The vehicle was towed to an authorized dealership, where technicians officially confirmed the failure. The dealer diagnosed the root cause as an internal electrical failure of the Motor Generator Unit (MGU / Belt-Driven Hybrid Starter Generator Assembly), which completely disabled the vehicle's charging and hybrid restart capabilities. The failed component is available for inspection.

While driving, the Instrument Cluster Display completely blanked out and ceased functioning. This sudden failure immediately disabled the digital speedometer, fuel gauge, engine temperature readings, oil gauge, and critical safety warning lights. In order to check my fuel levels, I have to log into an app on my phone, which is both unsafe and illegal to do while driving. The panel beeps a warning when I start my car, however I cannot see what the issue is because the display is black. Other 2020 Jeep Wranglers share this identical, well-documented cluster failure and are covered under an active recall. However, my specific VIN is currently excluded despite suffering from the exact same manufacturing defect. This issue presents an unreasonable risk to motor vehicle safety and requires immediate investigation to expand the recall scope.

On July 1,2026 , My 2020 Jeep wrangler jl sport died in the middle of traffic causing a safety issue. I was not able to start my jeep and move out of traffic. I was able to disable the transmission and roll out of the road. But it was very dangerous while cars were passing me and coming towards me. Also before I was able to disable to roll my steering column was locked. The cause of this safety issue is the set up of the batteries. A jeep has 2 batteries a main and underneath an auxillary battery. Without any kind of warning your battery can die caused by the drain of the auxillary battery on the main battery causing the main battery to just stop working without notice. This is the 2nd time this happened.I had to call a tow truck both times. 1st time 4/14/24, then on 07/02/2026 I had it towed to the same dealership as the time before. This is an on going issue with jeeps that have the 2 batteries. Not only is it unsafe but a costly issue.

PE25014 · Instrument Panel Cluster (ipc) Failure

Opened Oct 23, 2025 · No close date supplied

Status: open (inferred from source dates) · Electrical System: Instrument Cluster/panel

The Office of Defects Investigations (ODI) is opening a Preliminary Evaluation on 2020 Model Year Jeep Gladiators and Wranglers involving a malfunctioning Instrument Panel Clusters (IPC) resulting in the loss of important vehicle metrics and other status information.  ODI has received 89 Vehicle Owner Questionnaires (VOQs) alleging a complete or partial loss of the IPC display while driving.  The subject vehicles' IPC display includes the speedometer, fuel gauge, engine temperature, turn signal indicators, warning light, and other gauges that are normally illuminated while the vehicle is in operation.  Loss of the fuel gauge while driving may lead to an inability to determine the fuel level and result in a loss of motive power, and the loss of other safety-related information may impede a driver’s ability to take action to prevent a safety risk.  Furthermore, an IPC that is suddenly not visible to the driver may divert the driver’s attention from the driving task, potentially causing a vehicle crash. ODI is opening this Preliminary Evaluation to evaluate the scope, severity and frequency of the alleged IPC malfunctions and to assess potential safety-related consequences. To review the ODI reports cited in the Opening Resume ODI Report Identification Number 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
