2025-2027 Cadillac Optiq Recall: Window Automatic Reversal System Malfunction/FMVSS 118

A dealer told General Motors that the front windows on four 2026 Cadillac Optiq vehicles did not appear to stop and reverse on an object when they were closed from the key fob, and a GM brand quality manager reported it internally on June 26, 2026. GM's closure hardware team tested five vehicles in July, and four of them failed to meet the federal stop-and-reverse requirement consistently.

GM filed campaign 26V612 with NHTSA on September 24, 2026 for 29,347 Optiq vehicles from model years 2025 through 2027. The company lists the estimated share of that population with the condition at 100%.

The Issue

Express-up closes a window completely from a single command. Federal Motor Vehicle Safety Standard No. 118 requires a window closing that way to stop and reverse when it meets an obstruction, and GM's filing cites section S5.1 of the standard.

The Optiq's front windows may fail to stop and reverse during the final 13 mm of upward travel, about half an inch, when express-up is triggered from the key fob.

GM's supplier set the upper travel range of the anti-pinch protection too far below the upper header of the door, so the protection stops short of the top of the window opening. The filing names Kwangjin America of Warren, Michigan as the supplier and identifies three front side door window regulator calibration data files in the body control module: 85738535, 85738536 and 85878204.

GM classifies 26V612 as a noncompliance recall. NHTSA's consequence statement says a closing window that does not reverse can pinch a passenger before retracting, increasing the risk of injury.

Affected Models

Model	Model year	Production dates	Units
Cadillac Optiq	2025	Jul 24, 2024 - Mar 12, 2026	12,558
Cadillac Optiq	2026	Jun 5, 2025 - May 29, 2026	10,201
Cadillac Optiq	2027	Mar 3, 2026 - Sep 22, 2026	6,588

GM identified the vehicles from manufacturing records. The production dates are as GM filed them, and the three model-year windows overlap.

Revised calibrations went into GM's assembly plant on September 22, 2026, the last build date in the recall population.

Chronology and Investigation

The brand quality manager's June 26 report went to the company's Speak Up For Safety program. The filing does not date the dealer's notice.

From July 8 through July 22, GM's closure hardware team tested five vehicles under section S5 of the standard. When the angle of the cylindrical test rod was varied, four vehicles failed to meet the stop-and-reverse requirement consistently with express-up activated from the fob. GM opened a product investigation on July 28.

GM's Safety Field Action Decision Authority decided on the noncompliance recall on September 17, and dealers were notified on September 24, the day the report was filed.

Reported Incidents

GM told NHTSA it is not aware of any field complaints associated with the condition. The Part 573 report mentions no injuries.

Remedy and Notification

GM will update the front side door window calibrations in the body control module. Owners of vehicles that can take over-the-air updates, and who have accepted GM's terms and conditions, can install the update without a dealer visit. Any owner can have a GM dealer do it instead, and the dealer bulletin restricts the work to authorized EV dealers.

The revised calibration raises the upper travel range of the anti-pinch protection.

Owner letters are expected to mail on November 9, 2026. VINs became searchable on NHTSA.gov on September 24. GM's number for the recall is N262567230, and Cadillac customer service is at 1-800-458-8006.

Every covered vehicle is still under warranty, so GM is not offering reimbursement for earlier repairs. Dealers must hold any affected Optiq in inventory until the update is installed.

Symptoms to Watch For

GM's filing lists no warning that precedes the condition.

A front window closing from the key fob. The condition applies to the last 13 mm of travel at the top of the glass. Until the update is installed, an owner closing the windows from the fob can check that nobody has a hand on the top edge of either front window.

An update prompt on the center screen. GM's over-the-air notice reads "Vehicle update is available" with an install time of 10 minutes, and the detail screen names GM Recall No. N26-2567230.

The decline screen. GM's text for it says an owner who declines the update will no longer be able to install it over the air and will need a dealer.

How Long Will the Recall Repair Take?

The over-the-air install takes up to 10 minutes, according to the screen text GM filed with NHTSA. The vehicle has to be parked and turned off, it cannot be driven during the update, and door locks, windows and chimes may not work. GM's text tells owners who leave the vehicle not to lock occupants inside.

At a dealer, GM allows 0.5 hour of labor to reprogram the body control module, or 0.2 hour when the technician finds the module already carries the revised calibration. The repair needs no parts.

Bottom Line

The recall takes in Optiq production from July 24, 2024 through September 22, 2026, and the remedy is a 10-minute software install that owners with over-the-air updates can run where the vehicle is parked. An owner who would rather not wait for the November 9 letter can check the VIN on NHTSA.gov now.

A dealer's report on four 2026 Optiq vehicles started the investigation, and four of the five vehicles GM then tested did not consistently meet the FMVSS 118 stop-and-reverse requirement when the test rod's angle was varied and express-up was activated from the key fob. GM reports no field complaints. The fix is a body control module calibration delivered over the air or at a dealer.

NHTSA's vehicle records show two earlier campaigns that include the Optiq: 25V704, covering 21-inch Continental tires on the 2025-2026 Optiq and Chevrolet Equinox EV, and 26V114, an FMVSS 208 noncompliance over the electronic owner's manual download that spans about 40 GM model lines. 26V612 is the first to cover all three Optiq model years.
