Ford Motor Company told federal safety regulators on September 9 that a small metal burr on a bracket can slice open the right-hand side curtain airbag in 2,711 Ford Broncos built for the 2026 model year. The fault sits on a part most owners will never see, tucked above the door line where the curtain stays folded until a crash or rollover triggers it.
If the bag tears while it inflates, it deflates faster than designed, and the person it was meant to cushion loses protection when the head is closest to the glass and pillar. Ford reported no crashes, injuries, warranty claims or customer reports tied to the problem as of August 18, the date its filing uses for incident data.
A deburring step that vanished from a supplier’s line
Ford’s recall filing, which NHTSA indexes as campaign 26V580 (Ford’s own reference is 26S64), traces the burr to a layout change at a supplier rather than to a design flaw in the Bronco. According to the Part 573 report, a Tier 2 supplier, Multitech of Bolingbrook, Illinois, eliminated its deburring stage after changing its production layout. Bracket blanks that should have been smoothed went on to the Tier 1 supplier, Joyson Safety Systems of Auburn Hills, Michigan, which builds the side air curtain module that Ford installs.
Deburring is a routine finishing operation. Stamped steel leaves a sharp raised lip along the cut edge, and a tumbling or grinding pass removes it. Skip that pass on a bracket that sits close to a folded fabric bag, and the edge is positioned to catch the fabric the instant the inflator fires.
Ford’s own wording in the Part 573 report is that the metal bracket on the right-hand side air curtain “may have a metal burr, creating the potential for a tear upon deployment.” NHTSA’s summary of the same campaign spells out the consequence in plainer terms: a torn air bag may fail to properly restrain an occupant during a crash, increasing the risk of injury. The 2,711 figure is the number of trucks Ford says are potentially affected, drawn from the production window rather than from inspection of each bracket.
The July 16 lot-acceptance test that found a 20-millimetre tear
The defect surfaced through supplier testing rather than a field failure. Ford’s report says Joyson’s lot-acceptance testing on July 16, 2026, turned up a 20-millimetre tear in the right-hand side curtain of a test unit. A lot-acceptance test pulls sample parts from a production batch and inspects or deploys them before the batch ships, which is how one torn bag in a sample can condemn a whole run of brackets.
Ford’s records, as summarized by autoevolution, put the affected production window between June 27 and July 26, 2026, at Michigan Assembly Plant in Wayne. That is about one month of output, which is why every affected truck is a 2026 model and why the count stops at 2,711 rather than reaching into earlier Bronco years.
The remedy: more clearance between bracket and bag
The repair does not replace the airbag. Per the NHTSA campaign record, dealers will remove the contact condition between the burr and the curtain by adjusting the spacing between the bracket and the airbag, at no charge to the owner. Ford mailed interim notification letters on September 15, and letters announcing that the remedy is ready are expected around October 30, 2026. The NHTSA component code for the campaign is the curtain-type side and window airbag assembly, and only the right-hand side is named in the filing.
Curtain airbags carry a heavy load in side impacts because there is very little room between an occupant and intruding structure. NHTSA’s own airbag guidance notes that side-impact bags inflate even more quickly than frontal ones, since there is less space between the occupant and the striking object, and that they work together with seat belts. A bag that rips mid-inflation undercuts the one property that design depends on, which is speed.
Checking a 2026 Bronco before the remedy letter arrives
Vehicle identification numbers became searchable on NHTSA’s portal on September 10. Owners can enter the 17-character VIN at NHTSA’s recall lookup, where the agency states that manufacturers must repair, replace, refund or, in rare cases, repurchase a recalled vehicle at no cost to the owner. Ford’s customer line for the recall, 1-866-436-7332, is printed on the NHTSA record under Ford reference 26S64.
The filing describes no driving restriction and no warning-light behavior, and the only published fix is the dealer spacing adjustment. With remedy letters not expected until late October, the weeks between the interim notice and the repair are the least documented stretch of the recall.
The number to track is how many of the 2,711 trucks Ford has repaired once NHTSA posts completion data for 26V580, because a burr behind a headliner gives an owner nothing to see or hear.
