Hyundai Motor America (Hyundai) is recalling certain 2024 IONIQ 6 vehicles. The differential gear bolts in the gear drive unit may not be tightened properly, which can result in a loss of drive power or cause the differential to lock up.

Kia America, Inc. (Kia) is recalling certain 2023 Niro EV and 2024 EV9 vehicles. The differential gear bolts in the gear drive unit may not be tightened properly, which can result in a loss of drive power or cause the differential to lock up.

Porsche Cars North America, Inc. (Porsche) is recalling certain 2020 Porsche 911 Carrera 4S Coupe vehicles. The front axle differential bracket may not have been tightened correctly. If it comes loose, the differential could potentially cause damage to surrounding components.

Chrysler (FCA US LLC) is recalling certain 2014-2017 Jeep Cherokee vehicles equipped with a two-speed Power Transfer Unit (PTU). Relative movement in the Power Transfer Unit (PTU) between the differential input splines and the transmission output shaft may cause some input spline teeth to wear off, which may eventually cause a loss of engagement between the transmission and the differential inside the PTU. If this occurs, power cannot be transferred between the front wheels and the transmission which results in a loss of drive while the vehicle is in motion and a loss of the Park function while stationary.

Chrysler (FCA US LLC) is recalling certain 2019 Jeep Grand Cherokee and Dodge Durango vehicles. The front differential may have been assembled with pinion gears that are insufficiently hardened, which can lead to the gear teeth wearing down. If both pinion gears have their teeth sufficiently worn off, torque power can not be transferred from the front wheels to the driveline, resulting in loss of power while driving and loss of the PARK function when stationary.

Ford Motor Company (Ford) is recalling certain 2020 F-550 and 2021 E-350 and E-450 vehicles. The rear axle differential fluid may be below the minimum level, possibly resulting in a failure of the rear axle assembly and driveshaft separation.

General Motors LLC (GM) is recalling certain 2014-2015 Cadillac CTS-V Sport vehicles equipped with 3.6L Twin Turbo V6 engines. The roll pins in the rear-axle differential may fracture.

Vantage Mobility International, LLC (VMI) is recalling certain 2017 Chrysler Pacifica lowered floor vehicles modified by VMI. The rear pinion bracket on both sides of the vehicle may crack, causing the axle not to be centered and the wheel to wobble.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2016-2017 Tacoma vehicles. Oil may leak from the area where the rear differential carrier is assembled to rear axle housing.

Chrysler (FCA US LLC) is recalling certain 2016-2017 Ram 1500 trucks. The differential pin retaining screw may come loose while driving, potentially causing the differential to break or lock up.

Chrysler Group LLC (Chrysler) is recalling certain model year 2005 Dodge Ram 1500 trucks manufactured January 28, 2004, to August 3, 2005. In the affected vehicles, the rear axle pinion nut may loosen due to an undersized spline on the pinion gear.

Chrysler is recalling certain model year 2009-2012 Ram 1500 trucks manufactured from February 27, 2008, through June 30, 2009, and from December 1, 2009, through October 20, 2011; model year 2009-2011 Dodge Dakota trucks manufactured from February 27, 2007, through June 30, 2009, and from December 1, 2009, through September 30, 2011; model year 2009 Chrysler Aspen trucks manufactured from January 3, 2008, through December 18, 2008; and model year 2009 Dodge Durango trucks manufactured from January 3, 2008, through December 18, 2008. The rear axle pinion nut may loosen due to an undersized pinion spline that can allow relative motion between the nut and companion flange.

Chrysler is recalling certain model year 2009-2010, Ram 1500 and Dodge Dakota trucks, manufactured from July 1, 2009, through November 30, 2009, because the rear axle pinion nut may loosen due to a lack of adhesive.

ON CERTAIN SPORT UTILITY VEHICLES, THE BOLTS THAT HOLD THE FRONT DIFFERENTIAL, THE RIGHT OUTPUT SHAFT HOUSING FLANGE AT THE ENGINE, AND THE RIGHT-HAND ENGINE SUPPORT MAY BE INSUFFICIENTLY TIGHTENED.

ON SOME MANUAL TRANSMISSION TRUCKS EQUIPPED WITH THE FX4 PACKAGE, THE REAR AXLE DIFFERENTIAL CASE COULD FRACTURE UNDER A HIGH TORQUE EVENT SUCH AS WHEN CUSTOMERS ACCELERATE RAPIDLY FROM A STOP OR WHEN A SPINNING TIRE SUDDENLY GAINS TRACTION.
