They charged $1567 to replace it which included $1200 in labor and recommended I contact GM to see if they would compensate me since it was a known issue and the car was only 2 months off warrantee. GM refused to compensate me for the faulty harness. The Bolt has 19K miles on it, is kept in a garage and has never been in an accident.”

It happened first time July 14 and then again Aug 4. Customer care at GM says it is a known problem and they will notify when a fix is available.
