3 recalls.

22V465000

Date: 2022-06-30. Systems: SERVICE BRAKES, HYDRAULIC.

Defect: General Motors, LLC (GM) is recalling certain 2018-2020 Buick Regal vehicles. In the event of a vacuum-power brake assist failure, a software error in the electronic brake control module (EBCM) may result in a loss of power brake assist. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 135, "Light vehicle brake systems."

Consequence: A loss of power brake assist can extend the distance required to stop the vehicle, increasing the risk of a crash.

Remedy: Dealers will update the EBCM software, free of charge. Interim owner notification letters advising owners of the safety risk were mailed on August 19, 2022. Owner notification letters were mailed September 16, 2022. Owners may contact Buick's customer service at 1-800-521-7300.

Do not drive: No. Park outside: No.

18V576000

Date: 2018-08-30. Systems: SERVICE BRAKES, HYDRAULIC.

Defect: General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Equinox, Impala, Cruze, Volt and Bolt EV vehicles, GMC Terrain vehicles, Buick Lacrosse and Regal vehicles, Cadillac XTS and XTS Professional vehicles and 2018 Chevrolet Malibu vehicles. The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.

Consequence: A reduction of braking performance can increase the risk of a crash.

Remedy: GM will notify owners, and dealers will bleed the vehicle's brake system, free of charge. The recall began October 11, 2018. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 18279.

Do not drive: No. Park outside: No.

18V230000

Date: 2018-04-12. Systems: SEAT BELTS.

Defect: General Motors LLC (GM) is recalling certain 2018 Buick Regal vehicles. During the manufacturing process, the rear seat belts may have been improperly routed around the bolster bracket on the rear outboard seats, which can cause inadequate restraint of the passengers.

Consequence: If the seat belt fails to adequately restrain the passengers in a crash, it can increase the risk of injury.

Remedy: GM will notify owners, and dealers will inspect the rear outboard seat belts, correcting the routing of the seat belts as necessary, free of charge. The recall began May 14, 2018. Owners may contact Buick customer service at 1-800-521-7300. GM's number for this recall is 18117.

Do not drive: No. Park outside: No.

Desiccated Air Bag Inflator Rupture

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupt

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
