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.
