Affected models: 2014 Chevrolet Malibus with a 2.5-liter four-cylinder engine and equipped with an engine start-stop feature are affected.
Number of affected models: About 140,067 vehicles are involved in the recall.
The fix: GM has begun sending letters to dealers in regards to the recall campaign. Owners will begin to receive written notification their vehicle is affected shortly. So far, no fix for the faulty parts has been named.
Contacts: Those with an affected vehicle may contact their local dealer, or Chevrolet directly at 1-800-222-1020.
