problem #2

Dec 032014

Envoy SLT 4200

  • Automatic transmission
  • 75,765 miles

Exhaust Manifold Bolts broke off and then the Manifold cracked... The dealer had 3 other 2008 Envoys in the shop with the exact same problem... This is a manufacture defect and should have been taken care of by GMC..!!! Money that was needlessly spent on a common problem..!!!
