24V-652Sep 5, 2024
Electrical System: Instrument Cluster/Panel

Chrysler (FCA US, LLC) is recalling certain 2020-2024 Jeep Gladiator and 2018-2024 Jeep Wrangler vehicles. The instrument panel cluster may experience an internal short circuit and fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 101, "Controls and Displays."

Risk and remedy
Risk: An instrument panel that fails to display critical safety information, such as the speedometer or warning lights, can increase the risk of a crash.
Remedy: Dealers will replace the instrument panel cluster, free of charge. Owner notification letters were mailed between October 3, 2024, and January 23, 2025. Owners may contact FCA customer service at 1-800-853-1403. FCA's number for this recall is 30B.

18V-332May 17, 2018
Electrical System:Wiring

Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.

Risk and remedy
Risk: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.
Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.

Instrument panel cluster (ipc) failure. Open.

NHTSA summary
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.

Loss of motive power. Open.

NHTSA summary
The Office of Defects Investigation (ODI) has identified 68 Vehicle Owner Questionnaire (VOQ) reports for model years (MY) 2021 through 2024 Jeep Wrangler 4xe vehicles alleging a loss of motive power. Recall 22V-865 was issued by the manufacturer to address an engine shutdown condition in certain MY 2021-2023 Wrangler 4xe vehicles. The complaints noted here contain both post recall remedy failures and failures in vehicles not included within the scope of 22V-865. An analysis comparing complaints received before the issuance of recall 22V-865 and complaints outside the scope of the recall has been conducted. The results show the current complaint rate is higher in the out of scope vehicles than it was for vehicles that were later covered by the recall. ODI is opening this Recall Query (RQ) to assess the severity of the alleged defect in vehicles not included in recall 22V-865.ODI will also assess the scope and remedy effectiveness of the recall.

High pressure fuel pump failure. Open, led to recall 24V-957.

NHTSA summary
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

Totally integrated power module failure. Closed jul 24, 2015.

NHTSA summary
In a letter dated August 21, 2014, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a defect investigation of alleged failures associated with the Totally Integrated Power Module (TIPM) installed in Chrysler SUV?s, trucks, and vans beginning in the 2007 model year. The petitioner alleges that TIPM defects may result in engine stall, airbag non-deployment, failure of fuel pump shutoff resulting in unintended acceleration, fire, and other symptoms. On September 25, 2014, the Office of Defects Investigation (ODI) opened DP14-004 to evaluate the petition for a grant or deny decision. ODI analyzed complaint data provided by CAS as well as complaints submitted to ODI from consumers. In total, there were 296 complaints submitted by the petitioner in the original petition and five supplements, including 271 complaints related to the subject vehicles equipped with TIPM-7. Approximately 3 percent of CAS complaints are related to vehicles equipped with TIPM-6 and ODI?s review of these complaints did not identify any safety defect trends. ODI conducted a detailed review of complaints narratives submitted by CAS and consumers including careful analysis of vehicle repair histories, warranty claims obtained from the manufacturer and any available Customer Assistance Inquiry reports (CAIR). Analysis of the field data indicated that MY2011-2013 Jeep Grand Cherokee and Dodge Durango vehicles exhibited significantly higher compla

Skid plate debris fires. Closed aug 7, 2012, led to recall 12V-216.

NHTSA summary
In a letter dated May 15, 2012, the Chrysler Group LLC (Chrysler) submitted a Defect Information Report to NHTSA identifying a safety defect regarding fires originating between the transmission skid plate and the exhaust catalyst in approximately 65,246 model year (MY) 2010 Jeep Wrangler 4x4 vehicles with automatic transmissions (NHTSA Recall 12V-216).According to Chrysler, changes to the exhaust system for MY 2010 resulted in reduced clearances between the exhaust catalyst and the skid plate.If debris collects in the area of the skid plate and is not removed, there is an increased potential for underbody debris fires.ODI's analysis of skid plate area fires in the MY 2010 Wrangler vehicles with automatic transmissions found that the rate increased significantly from approximately 1.7 fires per 100,000 vehicle years in the MY 2007 through 2009 vehicles with the prior exhaust design to approximately 14.8 fires per 100,000 vehicle years in MY 2010 vehicles, a nearly 800 percent increase.In analysis of both Vehicle Owner Questionnaire (VOQ) data submitted to the Office of Defects Investigation (ODI) and Chrysler's consumer complaint data submitted to ODI, 35 unique reports were identified by Chrysler alleging fire in subject vehicles with origins near the engine compartment or in the underbody area directly beneath and to the rear of the engine compartment.Chrysler's assessments of the 35 reports of fire were categorized by likely causes.Eleven of the fires were determined to be

Fuel spill during refueling. Closed feb 16, 2011.

NHTSA summary
ODI found the rate of warranty claims related to fuel spit back on the subject vehicles is lower than other vehicles previously recalled to correct defects related to fuel spit back.Although the rate of complaints reported to the agency on the subject vehicles is higher than or similar to the rates experienced in previous investigations where safety recalls were conducted, ODI suspects that the NHTSA safety complaints submitted by subject vehicles owners may have been influenced by internet related publicity both before and during this investigation.A safety-related defect trend has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.See attached report for additional information.In addition, Chrysler is initiating a lifetime warranty program, at no cost to the consumer, to address the fuel spit back problem in approximately 135,000 model year 2007-2008 Jeep Wrangler vehicles built from March 1, 2007 to March 31, 2008.Chrysler will notify all affected vehicle owners of this action.Consumers should refer to the warranty and service bulletins and sample owner notification letter available in the investigative file.The vehicle build date can be found on the certification

What owners wrote

“Numerous lights flash on dash-engine fan turns on high speed, coolant temp stops reading, check engine light comes on, unable to accelerate. Pull over but will not turn off. From what I’m reading it’s the CAN bus module and from what I’m finding on this site Jeep has many electrical failures but can’t fix it? Jeep should do what’s right and stand behind its product.”

Filed Apr 7, 2026

“My car randomly illuminates every light on the dashboard and my speedometer will say zero mph and I lose all power steering and have to put my car into neutral and roll to a stop because my brakes won’t work either. Then I cannot turn off the ignition or accessory. Check engine light is on and my car starts but there are no brakes or power steering. Thankful my kids were not in the car!”

Filed Aug 8, 2025

“The check engine light came on in my car. I was waiting for the dealer to call me to fix it for the 3rd time. I was on my way home when every electrical option on the vehicle turned on- wipers, lights, dash lights, brake- which caused the car to brake- then it turned off and I had no brakes, the car had no steering, it accelerated and I went off the road.”

Filed Jul 2, 2025

“The dash board stared to flash all sorts of symbols check engine light, auto start stop, sway bar disconnect unavailable, shifter problem. And then the power steering does not work, sometimes the throttle has no power, and sometimes the engine shuts off.”

Should you keep driving it?

This page can't tell you that. 1 of 48 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
