Body & structure, Visibility (wipers, glass) Vehicle recall #23V741000 · 2023 · 7 vehicles

What's wrong: The front, rear, and fixed side windows May not be properly secured and can detach. In addition, the front air bags May not be properly supported by the windshield during deployment.

Why it matters: Detached windows May cause a road hazard and increase the risk of a crash or injury. Improperly supported air bags can increase the risk of injury during a crash.

The fix: Dealers will inspect and replace the front, rear, and fixed side windows, as necessary, free of charge. Owner notification letters were mailed December 15, 2024.

Electrical Vehicle recall #24V115000 · 2024 · 31,848 vehicles

What's wrong: The 80-amp fuses May have been manufactured incorrectly, which can cause the fuses to fail.

Why it matters: An 80-amp fuse that fails can result in a sudden loss of drive power or a loss of critical safety functions such as the restraint systems or instrument cluster, increasing the risk of a crash or injury. Additionally, there could be an increased risk of a fire.

The fix: Dealers will replace the main fuse boxes, free of charge. Owner notification letters were mailed April 5, 2024.

Body & structure Vehicle recall #24V658000 · 2024 · 4 vehicles

What's wrong: The integral carrier that supports the engine May fail due to improper welds, which can cause a loss of vehicle control.

Why it matters: A loss of vehicle control increases the risk of a crash.

The fix: Dealers will replace the integral carrier, free of charge. Owner notification letters were mailed October 11, 2024.

Transmission & drivetrain Vehicle recall #24V862000 · 2024 · 3 vehicles

What's wrong: The bolts that secure the rear axle differential to the rear axle carrier May come loose, which can result in a separation of the drive shaft from the rear axle differential.

Why it matters: Driveshaft separation can cause a loss of drive power, increasing the risk of a crash.

The fix: Dealers will repair the rear axle differential bolt connection as necessary, free of charge. Owner notification letters were mailed January 10, 2025.

Electrical Vehicle recall #25V255000 · 2025 · 443 vehicles

What's wrong: An incorrect fuse box that was not designed for the vehicle May have been installed.

Why it matters: An incorrect fuse box can result in a sudden loss of drive power or a loss of critical safety functions such as the restraint systems or instrument cluster, increasing the risk of a crash or injury. Additionally, there could be an increased risk of a fire.

The fix: Dealers will inspect and replace the main fuse boxes, free of charge. Owner notification letters were mailed June 6, 2025.

Body & structure Vehicle recall #25V379000 · 2025 · 92,851 vehicles

What's wrong: In certain crash scenarios, where the rear occupant's head contacts the c-pillar, the pillar May not absorb an adequate amount of the impact. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (fmvss) number 201, "occupant protection in interior impact."

Why it matters: In the event of a crash, insufficient impact protection can increase the risk of injury.

The fix: Dealers will modify the roof lining and c-pillar trim, free of charge. Owner notification letters were mailed July 9, 2025.

Steering Vehicle recall #25V533000 · 2025 · 3,749 vehicles

What's wrong: Please see the recall report for a complete list of models. The steering coupling bolt May have been improperly tightened, allowing the steering coupling to loosen from the steering rack.

Why it matters: A loose steering coupling can cause a loss of steering control, increasing the risk of a crash.

The fix: Dealers will tighten the steering coupling bolts as necessary, free of charge. Owner notification letters were mailed October 6, 2025.

Latches & locks Vehicle recall #26V481000 · 2026 · 310,667 vehicles

What's wrong: Please refer to mbusa's recall report for specific model information. The micro-switch in the driver's door lock May corrode and fail to detect an open door, preventing the electronic parking brake or "auto-park" feature from engaging automatically. This May result in a vehicle rollaway.

Why it matters: A vehicle rollaway increases the risk of a crash or injury.

The fix: Dealers will replace the driver's door lock, free of charge. Owner notification letters are expected to be mailed September 18, 2026. This will be a phased campaign, with the remedy becoming available in different phases based on model and model years.
