What owners report

  • Some drivers report sudden and complete brake failure on downhill slopes despite continuous braking, leading to low-speed collisions.
  • Owners describe the car unexpectedly accelerating or rolling forward into parked vehicles or objects with little braking response.
  • Drivers report a 'shift to park' warning appearing on the dashboard at highway speed, followed by sudden loss of engine power and the car stalling in traffic.
  • Some owners experienced a total loss of power steering while driving, accompanied by a dashboard error message, making the car hard to turn.
  • Owners note the regenerative braking paddle slows the vehicle without reliably triggering the brake lights, raising rear-collision risk.
  • A few drivers report a burnt plastic smell from under the hood after the gas engine reaches operating temperature.

2018 Chevrolet Volt recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 18V673000Sep 26, 2018Seat Belts15,800 vehicles

    Seat belts:rear/other

    General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

    Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.

    Remedy: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018. Owners may contact 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 18315.

  2. NHTSA 18V576000Aug 30, 2018Brakes210,628 vehicles

    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.
