The engine in my 2020 Jeep Wrangler Sahara suddenly failed and was diagnosed by the dealership as a complete internal failure involving the lifters and camshaft. The dealership explained that this type of failure can spread metal fragments throughout the oil system, requiring a full engine replacement. This creates a serious safety hazard, as the engine can shut down unexpectedly while driving, putting both the driver and others at risk. The issue has been confirmed by the dealership’s technician and shop foreman, and the vehicle has been at the dealer for over a month awaiting a replacement engine, which is currently on national backorder. There were no prior warning lights or error messages before the failure. The failure occurred without warning, and the vehicle is not drivable. This problem appears to be affecting multiple Jeep Wrangler owners and may represent a systemic defect that should that should be investigated!

Had to take my 2020 wrangler in to have accessory battery replaced as it had drained my newly purchased battery and my car wouldn’t start. Repair shop replaced both batteries and about a week later the check engine light came on for about 2 minutes then went off so I chalked it up to the battery replacement. It didn’t come back on again until about 3 weeks later when I started feeling a slip when going in to second gear. When I got home after having that issue I noticed a small collection of what looked to me like transmission fluid on my garage floor so I had the car towed to the repair shop again. They informed me that engine oil was mixing with coolant due to a bad oil cooler. Between that diagnosis and my car completely breaking down and cracking my engine block the car was driven a total of 14 miles at the most. There was never any other signs prior to me taking it to the shop that the oil cooler had gone bad and even when they replaced the batteries no codes came up for the bad oil cooler and nobody noticed anything while working in the area. . Since then I have learned that this has been an ongoing issue with the wrangler since at least 2012 models and there has been several class action suits that were settled out of court I’m assuming so they don’t have to spend the money recalling and repairing every affected vehicle and finding a fix for future models. Meanwhile I have only had my car for 2 years as of last week and now am being charged $15000 $8000 of which I have to pay up front to even find out how long the parts needed will be on back order. Could be a week could be a year. Not to mention that I have no car to drive and a car payment to make while I wait. This needs to be fixed as these cars are overheating out of nowhere and shutting down when it does. It’s a safety issue as well as a consumer issue.

My vehicle had a rough idling and then flashed an autostart symbol and stated on the dashboard that my autodash has been disabled. Later that day I drove my vehicle again, then the dashboard lit up like a christmas tree and every light was on and my car went limp. I pulled over on the side of the road and let my car stay off thinking it would help. Waited some time and tried to turn it on and it wouldnt turn back on until the 5th attempt. took my vehicle to jeep a few days later where they diagnosed it saying it needs a new ABS control module. However, the control module is on back order with no ETA in sight. There are multiple other people in my exact situation waiting 6+ months for their ABS control module. My car is undriveable as it has no traction control, will go limp, and no ABS system. I have been without my car for a month and they have not provided a loaner. To my research this has been an issue since september of 2023 and has yet to be a recall.

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
