problem #1

Oct 102020

Lucerne CXL 3.9L V6

  • Automatic transmission
  • 146,731 miles

Car running extremely well then, within minutes, engine was seized. Had a dealership investigate the coolant leak. Diagnosis was a leak coming out of the intake through the throttle body and out of the airbox. I had just purchased this vehicle 18 months ago with 75,049 miles on it. I invested money into the vehicle to keep it up, including a new fuel pump and fuse block. After $1,000+ into repairs this happened. Now I have expensive art.

Very disappointed in Buick for this problem not being a recall issue.
