Stellantis, the automotive group, has been compelled to initiate a recall and repair campaign for a significant number of Ram 1500 and Jeep Grand Cherokee models in the United States for now. The reason behind this action is a potential defect in the vehicles’ 3.0-liter diesel engine, specifically the engine reluctor or tone wheel. We have personally seen this problem in house at GDL many times on the Facelift Diesel Grand Cherokee’s and can only assume this recall will make it’s way to Australia soon as the mechanical fix requires removal of the transmission.
A total of 80,629 vehicles are affected by the recall. Among them, the Ram 1500 models built from 2014 to 2019 bear the brunt, with 58,393 pickups falling within the recall range. These particular Ram trucks were manufactured between June 12, 2013, and December 13, 2019. The recall also encompasses 22,236 Jeep Grand Cherokee models from the 2014 to 2020 model years, produced between December 19, 2012, and October 13, 2019.
Stellantis has identified a potential issue with the magnetic signal material on the reluctor wheel, which may experience delamination. If this occurs, the reluctor wheel’s ability to transmit a signal to the crankshaft position sensor is compromised, resulting in the loss of engine synchronization between injector pulses and cam timing. Consequently, the engine may stall, and restarting the vehicle could become problematic. It is important to note that affected vehicle owners will not receive any warning sign indicating the presence of this condition. Stellantis conducted an investigation into stall patterns and vehicle history, which revealed that the problematic vehicles were equipped with the Gen II 3.0-liter diesel engine, and the tone wheel was identified as the root cause of the stalling issue.
While Stellantis has not received reports of any accidents or injuries related to this problem, the company has recorded 10 instances of customer assistance, 611 warranty claims, and three field reports between September 29, 2015, and May 23, 2023, across all markets.
To address the issue, authorized dealers will update the powertrain control module software, enabling the vehicle to maintain propulsion by relying on the camshaft position signal in the event of signal loss.
Stellantis is committed to ensuring the safety and satisfaction of its customers. By taking prompt action to rectify the potential defect, the company aims to resolve the issue and minimize any inconvenience or risks associated with the affected Ram 1500 and Jeep Grand Cherokee models.
