When I pulled my Jeep 4xe into my garage, I got an alert on my radio saying my Jeep needed to updated. I selected to go ahead and update it. The next time I drove my vehicle, I made it about a quarter mile. When I was crossing an intersection, all of the lights on my dash went crazy and my Jeep completely shut down. Luckily I could put it into neutral to coast through the busy intersection. It was very scary. I had to pull over, turn it off and back on again. It did start up and continued to drive. Now my check engine light is on.
Jeep pushed out an OTA update for their Uconnect system. Upon completion of this update, that occurred while I was driving, I lost control of my vehicle. My steering wheel locked up, all of the lights on my dashboard started flashing, and I was instructed to pull the jeep over. I was unable to operate the vehicle and had to be t…

Jeep pushed out an OTA update for their Uconnect system. Upon completion of this update, that occurred while I was driving, I lost control of my vehicle. My steering wheel locked up, all of the lights on my dashboard started flashing, and I was instructed to pull the jeep over. I was unable to operate the vehicle and had to be towed.
After the the latest U-connect update, my jeep will not run after about 30 seconds while driving. Stalls while in motion. Will restart, but then shuts off again. Has an engine code on dash.

We’ve experienced multiple ongoing issues with this vehicle, and the dealership’s only suggestion so far has been to file a lemon law claim. Last month, the car began jerking excessively while driving typically at speeds between 35–45 mph. The best way to describe it is that it feels as though all the wheels lock up at once, causing a loud tire-screeching noise. It was a frightening experience. The dealership claimed to have resolved the issue with a “software update.” However, just last night, my wife was stranded on the highway when the car suddenly started shutting down mid-drive, similar to what happens when a vehicle runs out of gas. The maximum speed she could reach was about 20 mph, and the check engine light came on. She switched from hybrid mode to eSave (gas-only mode), which allowed her to get home safely. This morning, she tested it again. The check engine light was initially off, but after a short drive, it came back on and the vehicle started shutting down again. This Jeep is a lease, and despite being in the shop five times three of those for a full week the dealership continues to “service” it without providing a real solution. We are extremely concerned about the vehicle’s safety and reliability at this point.
This issue happens after an update on the car. Within 10 minutes after the car update the engine light came on and the car shut down on the road completely unable to drive . Without a warning, car stop to a complete shutdown while driving. My safety was at risk 5 times almost got into a car accident due to this issue where the c…

Car stoped in the middle of the road, won’t shift out of park. All this after an “update”

A software update for the Uconnext system was pushed to the vehicle and accepted. Immediately after the car said the system was updated, the vehicle engine stopped completely, and the whole dashboard shut down. Restarted the car, but this repeated several times in a very short distance. The “D” was blinking in the transmission. It was barely possible to pull the vehicle over, as all power was lost. After some time stopped and waiting for a tow truck, driver pushed the factory reset button to reset the system. After factory reset, the car operated normally.

6PE25014 · 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

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
DP14004 · Totally Integrated Power Module Failure
Opened Sep 25, 2014 · Closed Jul 24, 2015
Status: closed (inferred from source dates) · Electrical System
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 complaint rates related to fuel pump relay (FPR) failures than other subject vehicles. In a September 3, 2014 letter to NHTSA, Chrysler submitted a Defect Information Report (DIR) identifying a defect in the FPR within the TIPM-7 which can result in a no start or stall condition in approximately 188,723 model year (MY) 2011 Jeep Grand Cherokee (WK) and Dodge Durango (WD) vehicles manufactured from January 5, 2010 through July 20, 2011 (14V-530).In a February 24, 2015 letter, Chrysler submitted a second DIR expanding the scope of the FPR defect condition to include an additional 338,216 MY 2012 through 2013 Jeep Grand Cherokee vehicles manufactured from September 17, 2010 through August 19, 2013 and MY 2012 through 2013 Dodge Durango vehicles manufactured from January 18, 2011 through August 19, 2013 (15V-115).ODI analysis of the CAS allegations of TIPM defects resulting in stall while driving, airbag non-deployment, unintended acceleration, fire and other faults identified a single defect condition related to 1 of over 60 different circuits in the TIPM assembly. The most common effect of this defect condition, related to the fuel pump relay, was a no-start concern, but it could also result in stall while driving (76 complaints). No valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components.Except insofar as the petitioner's contentions relate to the defect condition addressed by the Chrysler recalls, the factual bases of the petitioner's contentions that any further investigation is necessary are unsupported. In our view, additional investigation is unlikely to result in a finding that a defect related to motor vehicle safety exists or a NHTSA order for the notification and remedy of a safety-related defect as alleged by the petitioner at the conclusion of the requested investigation. Therefore, in view of the need to allocate and prioritize NHTSA's limited resources to best accomplish the agency's safety mission, the petition is den
