Fiat Chrysler Automobiles is calling back certain Dodge Durango and Jeep Grand Cherokee vehicles over an issue that could cause the engines to stall.

The NHTSA recall acknowledgement reveals that “the fuel pump relay inside the Totally Integrated Power Module may fail, causing the vehicle to stall without warning”.

The automaker explains that “feedback from dealers led to an [internal] investigation that discovered silicon deposits on the contact points of certain fuel pump relays may interrupt electrical current and prevent engine start-up and/or contribute to stall”.

The 2011-2013 Dodge Durangos included in this safety campaign were assembled between August 23, 2010, and August 19, 2013. The 2011-2013 Jeep Grand Cherokees were put together from February 24, 2010, to January 19, 2013. All of them are equipped with the 3.6-, 5.7 or 6.4-liter engines, and were previously recalled over the same issue. Out of the 528,594 units, it is estimated that all of them are affected by the aforementioned defect.

FCA is still working on the remedy and said that it will start informing owners via mail from January 3, next year. Upon finding a solution, authorized technicians will inspect and fix all of them. As usual, all repairs will be carried out free of charge.
