The short answer

NHTSA received General Motors LLC’s report on Jun 14, 2018. Copied from NHTSA on Oct 20, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

If the voltage drops, the vehicle may lose propulsion, increasing the risk of crash.

General Motors LLC (GM) is recalling certain 2013 Chevrolet Volt vehicles.

An update to the Hybrid Powertrain Control Module 2 (HPCM2) may have disabled the cell balancing function causing a low-voltage condition.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
