General Motors has issued a critical “Do Not Drive” warning and a Stop Delivery order for a small but highly dangerous batch of pickup trucks and SUVs. According to a recent filing with the National Highway Traffic Safety Administration (NHTSA), a manufacturing error left a crucial component out of the transfer case, which can cause the front and/or rear wheels to lock up entirely without warning while driving.

What is Causing the Issue?

The recall documents reveal that a supplier error at Magna Powertrain in Mexico resulted in transfer cases being assembled without an oil pick-up tube. Without this tube, the transfer case bearings do not receive proper lubrication, leading to catastrophic failure and sudden wheel lock-up. Some drivers may hear a grinding sound right before the wheels lock, which drastically increases the risk of a crash.

Which Vehicles Are Affected?

Fortunately, this is an extremely limited recall, affecting an estimated total of only 66 vehicles in the United States. However, because the risk is so severe, it applies to both brand-new 2026 models and older vehicles that may have received a replacement part. Please keep in mind that this recall strictly applies to vehicles equipped with 4-wheel drive (4WD) or all-wheel drive (AWD). Two-wheel drive models are not included.

Certain older SUVs may have had a defective service replacement transfer case installed between December 2025 and early 2026.

What Owners Need to Do

If you own an affected vehicle, GM’s instructions are clear: Do not drive the vehicle until the remedy is performed. GM is contacting owners directly to arrange for the vehicles to be towed to a local dealership for inspection and repair.

Dealerships will inspect the transfer case and replace the entire assembly free of charge. Owner notification letters are expected to be mailed out starting June 22, 2026. In the meantime, owners can contact customer service, use the GM Recall VIN Check Website or check the NHTSA recall site (Campaign Number: 26V289) to see if their specific VIN is included.
