problem #1

G80 3.8L

  • Automatic transmission
  • 59,000 miles

The check engine light came on and I had my mechanic diagnose it. The error code stated it was the thermostat. Unfortunately the whole unit had to be replaced. After discovering this issue I did some research and have found this to not be uncommon with the 2018 G80.
