Terrain Denali 3.6L V6

  • Automatic transmission
  • 45,000 miles

They tried to say it was our fault because we should have been putting additives in gas, which is NOT mentioned in the maintenance book. First we paid over a hundred dollars to clean it and it happened again immediately after cleaning, so they cleaned it again but codes (p0302 and p300) kept coming back. Finally they had us bring it back and it took 2 weeks to repair.
