What owners report

  • Brake pedal fails to slow the car during low-speed maneuvers like backing out of a driveway or approaching a drive-thru, sometimes leading to a crash into a fixed object.
  • Vehicle lurches forward on its own when the driver's foot comes off the brake pedal at low speed.
  • Engine RPMs surge to around 3,000 when the vehicle should be idling or shutting down at a stoplight, forcing the driver to shift to neutral.
  • Owners report the transmission hesitates or fails to shift gears, with a loud clanking noise when manually forcing a gear change.
  • Steering wheel jerks unexpectedly after the auto-stop/auto-start feature reactivates the engine.
  • Excessive interior moisture from the AC or heater fogs the windshield so badly that visibility is completely lost, even with defrost on.

3 NHTSA recall campaigns list this model year.

  1. NHTSA 22V465000Jun 30, 2022Brakes23,734 vehicles

    Service brakes, hydraulic:power assist:electric:control module:software

    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."

    Risk: 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.

    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.

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

    Seat belts:rear/other

    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.

    Risk: 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.
