In recent years, the automotive industry has witnessed a significant shift towards electric vehicles (EVs), with hybrid models like the Plug-In Hybrid Electric Vehicles (PHEVs) gaining popularity. However, this transition has not been without challenges, particularly concerning battery reliability and safety. A case in point is the recent issue with certain 2021-2023 model year Jeep Wrangler PHEVs.

The Core Issue

The heart of the problem lies in the high voltage (HV) battery of some Jeep Wrangler PHEVs, which have been reported to fail internally. This issue first came to light in May 2023 when the FCA Technical Safety and Regulatory Compliance (TSRC) organization received two field reports of 2021 Jeep Wrangler PHEVs catching fire due to the HV battery. Following these alarming reports, FCA bought back the vehicles for in-depth analysis. By November 2023, seven such incidents had been reported, prompting FCA US to initiate a voluntary safety recall of the affected vehicles.

Investigating the Cause

The root cause of these battery failures remains unidentified and under investigation. The suspect period for these faults began on September 18, 2020, with the issue being potentially linked to battery cells manufactured between January 21, 2021, and October 2, 2021. These dates were determined using supplier manufacturing records, indicating a specific window during which the faulty cells were produced.

Broader Challenges with EV Batteries

This situation with Jeep Wrangler PHEVs brings to light broader concerns in the EV industry regarding battery safety and reliability. Battery issues in electric vehicles can stem from various factors, including manufacturing defects, improper management of battery temperature, overcharging, or physical damage to the battery. Such problems can lead to reduced battery life, decreased performance, and in extreme cases, safety hazards like fires.

The recall of the Jeep Wrangler PHEVs underscores the importance of ongoing monitoring and quality control in the production of EV batteries. Manufacturers must implement stringent quality checks and improve battery technology to prevent such incidents. Furthermore, understanding and rectifying the root cause of these failures is crucial for the advancement and consumer confidence in EV technology.

Owners are advised not to recharge their vehicles, and to park outside and away from structures, until they are repaired. Dealers will update the high voltage battery pack software and replace the battery pack assembly if necessary. FCA US, LLC’s number for this recall is 89A and the NHTSA campaign number is 23V-787.

The case of the Jeep Wrangler PHEV batteries serves as a reminder of the complexities and challenges associated with the EV revolution. While the shift to electric mobility is imperative for sustainable transportation, it also demands heightened attention to the safety and reliability of EV components, especially batteries. As the industry evolves, continuous improvements and vigilance in battery technology and manufacturing processes will be key to ensuring the safety and satisfaction of EV users worldwide.

Fiat Chrysler Automobiles (FCA) USA will be contacting the owners of certain 2022 Ram trucks because their vehicles may have a manufacturing defect within the Engine Control Module (ECM) that could affect vehicle safety. This defect affects vehicles equipped with Cummins 6.7L turbo diesel engines and could result in an unexpected engine stall.

The RAM trucks affected by this defect include:

2022 Ram 2500
2022 Ram 3500
2022 Ram 3500 Cab Chassis
2022 Ram 4500 Cab Chassis
2022 Ram 5500 Cab Chassis

The FCA Technical Safety and Regulatory Compliance (TSRC) organization became aware of the problem in August 2022 when they were contacted by the RAM truck assembly plant regarding suspect ECMs manufactured with a defective component. According to the NHTSA safety report, some ECMs may have been manufactured with a misaligned capacitor that could short-circuit and create an internal loss of communication. This internal loss of communication could result in a loss of motive power and an increased chance of an accident.

The suspect period for these defective ECMS began on May 31, 2022, and ended on August 23, 2022, when the ECMs were quarantined. This time period was determined using supplier traceability and vehicle production records. Similar vehicles not included in the recall did not receive suspect ECMs or were repaired prior to release from the assembly plant control.

Owners who receive notices will be asked to return to their dealers to have ECMs in their trucks replaced. FCA US, LLC’s number for this recall is Z87 and the NHTSA campaign number is 22V-642.

Certain 2014-2020 Jeep Grand Cherokee and 2014-2019 Ram 1500 vehicles equipped with 3.0L diesel engines, could experience high-pressure fuel pump failure. If the pump fails while the vehicle is being operated, drivers will experience an unexpected loss of engine power and an increased chance of an accident.

In February 2022, Fiat Chrysler Automobiles (FCA) Technical Safety and Regulatory Compliance (TSRC) organization started an investigation into Jeep Grand Cherokee and Ram 1500 trucks, after receiving field reports that the fuel pump in some vehicles were prematurely failing. An investigation of the stall patterns and vehicle histories showed that the affected trucks were equipped with Bosch CP4.2 high-pressure fuel pumps (HPFP).

According to the defect report, a failure inside the fuel pump could introduce internal debris that could build up and cause fuel starvation. Fuel starvation may result in an unexpected loss of motive power, which could contribute to a vehicle to crash. The suspect period began on June 12, 2013, when 3.0L Diesel engines with suspect HPFPs were introduced into vehicle production, and ended on December 13, 2019, when 3.0L Diesel engines with suspect HPFPs were no longer used in vehicle production.

Warning signs that your vehicle may be experiencing this problem include:
Drivers may notice a Malfunction Indicator Lamp, a service Electronic Throttle Control indicator, a fuel leak at the HPFP, or excessive noise from the HPFP.

FCA US is aware of 215 customer assistance records, 1,061 warranty claims, and three field reports that could be related to this issue.

Owners receiving notices will be asked to return to their dealers to have the HPFP replaced. Dealers will also inspect the entire fuel system and replace components as necessary. FCA’s number for this recall is Z46 and the NHTSA campaign number is 22V-406.

Chrysler (FCA US, LLC) will be contacting owners of certain Chrysler, Alfa Romeo, and RAM vehicles for a problem affecting the fuel system. In total, approximately 236 000 vehicles are being recalled.

2020-2021 Alfa Romeo Stelvio and Alfa Romeo Giulia vehicles fuel line sensor housing may crack and leak fuel. NHTSA Campaign Number: 21V-878

The problem was traced to September 11, 2020, when defective fuel sensors were introduced into vehicle production, and ended on May 25, 2021, when the fuel sensors from the suspect batches were no longer used. The suspect population was determined using part traceability and vehicle production records.

According to the defect report, a leak in the fuel line sensor may cause fuel starvation of the engine and in rare circumstances, if the leaked fuel comes in contact with an ignition source, a fire could occur. A vehicle fire can result in an increased risk of occupant injury and/or injury to persons outside the vehicle, as well as property damage. Fuel starvation could also result in an unexpected loss of motive power.

2019 Fiat 124 Spider fuel pump failure may cause an engine stall. NHTSA Campaign Number: 21V-879

The suspect period began on April 6, 2018, when the defective fuel delivery module (FDMs) were introduced into vehicle production, and ended on October 18, 2018, when FDMs with improved molding of the impellers were implemented in vehicle production.

Some 2019 Fiat 124 Spider vehicles may have been manufactured with a fuel delivery module (FDM) with impellers that could deform. An FDM with a deformed impeller may interfere with other fuel pump components which can inhibit the operation of the fuel pump potentially causing fuel starvation. : Fuel starvation may result in an unexpected loss of motive power.

2019-2020 RAM 2500, 3500, 4500, and 5500 diesel trucks fuel pump failure may cause an engine stall.
NHTSA Campaign Number: 21V-880

The suspect period began on October 11, 2018, when Cummins 6.7L Turbo Diesel engines with suspect HPFPs were introduced into vehicle production, and ended on November 13, 2020, when Cummins 6.7L Turbo Diesel engines with suspect HPFPs were no longer used in vehicle production.

According to the defect report, the high-pressure fuel pump could fail and introduce debris into the fuel system. Fuel starvation and an unexpected loss of motive power could result without prior warning. Vehicle occupants may notice an illuminated Malfunction Indicator Lamp, a fuel leak or smell, abnormal engine noises, or a change in drive quality.

During a configuration review at the supplier for an unrelated manufacturing issue, FCA US LLC Product Engineering became aware of an error with an airbag squib driver circuit that identified three internal faults not mapped to a diagnostic trouble code (DTC). An investigation was opened and it was discovered that some 2021 Jeep Grand Cherokee, 2022 Jeep Wagoneer, and 2022 Jeep Grand Wagoneer vehicles may not set a DTC, and the airbag warning indicator may not illuminate.

The problem started in February 2021, when occupant restraint controllers (ORCs) with an incorrect software version were introduced into vehicle production, through to November 1, 2021, when the suspect ORCs were no longer used in vehicle production. Vehicle and supplier production records were used to determine the vehicles included in the recall population.

According to the defect report, “If specific ORC internal faults are active then a DTC will not be set and the airbag warning indicator may not illuminate. The internal faults will disable deployment of both the driver and passenger airbag squib 3 (related to airbag venting post-deployment) and knee airbags. The airbag warning indicator may not illuminate to notify the driver of possible compromised airbag system functionality. Reduced occupant protection in the event of a crash may result in an increased risk of injury to motor vehicle occupants.”

Owners receiving notices will be asked to return to their FCA dealers to have the occupant restraint controller reprogrammed with the correct software version that maps subject internal faults to a DTC. FCA US, LLC’s number for this recall is Y79 and the NHTSA campaign number is 21V-873.
