H3

  • 47,644 miles
2006 Hummer H3 47000 miles only 2 months out of warranty. Check engine light came on, noticed rough idle. Dealer says must replace head due to misfire and trouble with cylinder 5. dealer recognized common problem with this engine, but refused to do anything but discount the repair from 3200 plus tax down to 2800. This appears to be same engine problem as was covered for the Colorado, but GM refuses to help with H3!
