GM Recall Issued for Defective Third-Row Seat Belts

A GM recall has been issued on their full-size SUVs around a defect with third-row seat belts on the outboard positions.

Defective Third-Row Seat Belts

Passengers relegated to the cramped way-way back in General Motors’ lineup of land-yacht sized SUVS may have something else to complain about, aside from eating their knees. A GM recall has just opened up, detailing a defect in the third-row seat belt installation, specifically the outboard positions.

According to the National Highway Traffic Safety Administration (NHTSA) recall report filed on March 18, this GM recall affects close to 95,000 full-size SUVs under the General’s corporate umbrella. The number of impacted vehicles is as follows:

Only model year 2021 is included in this list, but if the vehicle does not have a third-row of seats or was built after November 18, 2020, it is not affected by this recall. General Motors estimates one percent of the vehicles were built with the defect.

What is the Issue with the Seat Belts?

The potential issue would have occurred during factory assembly. In some cases, one or both of the outboard seat belts were “inadvertently entrapped in or misrouted behind the outboard seat folding mechanism”. In this scenario, the seat belt can be damaged by the folding mechanism, which can in turn break during a crash. This of course represents a higher risk of injury.

GM discovered the problem in November 2020 during post-installation inspection at the factory. They’re instructing owners to look out for difficulty using the third-row seat belts and latching or operating the folding mechanism. General Motors dealers were notified of this recall on March 18, 2021. For impacted vehicles, they will inspect for damage and/or misrouting and either replace or reroute the seat belts.

GM’s Seat Belt Track Record

This is the latest in a string of GM recalls related to seat belt issues. In 2018, about 16,000 General Motors vehicles went under recall because seat belts were not switching into lock mode during child seat installation. Normally, when the seat belt is pulled all the way out and then released, it becomes “locked”. This is a common method for installing child seats because it keeps the seat snug against the vehicle.

NHTSA opened an investigation in 2019 on 1.4 million GM crossovers – the Acadia/Enclave/Outlook lineup – with faulty seat belts. The catalyst was a recall on the same vehicles from five years earlier that was supposedly handled by GM. The steel cables connecting front seat belts to the vehicle were wearing out and then separating which is a major safety hazard. When reports surfaced in 2019 that the work related to this 2014 recall was not completed, an investigation was initiated.

Last year, over 600,000 GM pickups and full-size SUVs where recalled for an issue with the front-row seat belts. Affecting vehicles with a front-row bench, the center seat had instances where the seat belt bracket was improperly installed. This could cause insufficient restraint to a passenger in the event of a crash.
