General Motors began mailing recall notification letters to affected owners today, September 14, as a federal safety action over a high-voltage battery fire risk takes effect across four of the company’s largest electric vehicle nameplates.
NHTSA campaign 26V494000 covers 2026 model year Cadillac Escalade IQ, Escalade IQL, Chevrolet Silverado EV, and GMC Sierra EV vehicles.
What the defect is
According to GM, an internal battery module component may not have been properly secured during assembly, creating the potential for battery damage and an increased risk of fire.
If the component shifts inside the battery pack, it could damage internal battery components and increase the risk of a fire while the vehicle is parked or being driven.
Because the issue occurs within the sealed battery assembly, owners are unlikely to detect the defect before damage develops. The recall summary published by the National Highway Traffic Safety Administration on behalf of General Motors does not describe the specific internal component involved. GM’s internal recall number for the campaign is N262562600.
A narrow but precisely traced production window
The battery recall covers just ten vehicles in the United States. Five Escalade IQ and IQL SUVs are among the ten vehicles receiving a new high-voltage battery under the recall. All were built in a two-week window between May 4 and May 18, 2026.
The battery module component in question, a sense line assembly, is put together at GM’s Factory Zero plant in Detroit and Hamtramck, Michigan. A press machine used in that operation was misadjusted during scheduled downtime. GM caught the issue on May 17, 2026, when two battery modules with sense line fingers not fully secured turned up at the company’s Ramos assembly plant in Mexico.
GM then used photographic manufacturing records to review the entire suspect population and whittled it down to 14 vehicles worldwide, ten of them in the U.S. No field incidents have been reported.
While the recall population is limited to a handful of vehicles, the concern is serious enough to prompt full battery replacements rather than attempting a module replacement or a repair inside the pack itself.
The recall involves the high-voltage battery assembly, and dealers will replace the high-voltage battery, free of charge. That approach mirrors GM’s handling of a prior electric vehicle battery safety action, where a manufacturing flaw also required a hardware remedy rather than a software patch.
A second recall lands on the same trucks
General Motors filed two separate safety recalls with NHTSA on July 30, 2026, and both land squarely on GM’s electric trucks.
One covers potentially cracked steel wheels on the 2026 Chevrolet Silverado EV and 2026 GMC Sierra EV, and the other covers a high-voltage battery defect with a fire risk that touches the Silverado EV, Sierra EV, and the Cadillac Escalade IQ and IQL.
The steel wheel recall, NHTSA campaign 26V496000, focuses on hairline cracks that can form at the disc vent holes. That campaign covers a significantly larger population: 952 trucks, comprising 513 Chevrolet Silverado EV and 439 GMC Sierra EV units from the 2026 model year. Under that campaign, dealers will inspect the spare and all four road wheels and replace them if necessary.
Neither recall carries a do-not-drive or park-outside advisory. Both sets of VINs became searchable on NHTSA.gov on July 30, 2026.
Remedy and owner contacts
Dealers will replace the high-voltage battery free of charge under the battery fire recall. All four affected nameplates are particularly expensive by default, with Chevrolet charging $55,895 before destination and other taxes for the entry-level Silverado EV configuration.
Owners may contact Cadillac customer service at 1-800-333-4223, GMC customer service at 1-800-462-8782, and Chevrolet customer service at 1-800-222-1020.
Owners of larger electric commercial vehicles facing similar battery concerns can also consult guidance on EV operating costs while their vehicles are being serviced. Anyone uncertain whether their vehicle is involved can run their 17-digit VIN at NHTSA.gov or through GM’s owner apps.
GM has zero reported incidents across both campaigns. GM has not disclosed whether any of the ten affected U.S. vehicles have already been brought in for service ahead of the formal notification.
