And it Head cracked. GM Knew this was a problem but is also hoping the owners would go way licking their wounds. I complained to GM. Got a take to to our dealer... who quoted me $3500 to fix with the exact same parts that failed. Went to an idenpendant engine rebuild shop. They put on a re-engineered head re-enforced where the hot and cool jackets sit to stop future leaking. Got absolutly no help from GM. It was my first and last GM I will ever own. So... Frankly my family and I will never buy another GM Product. Looking forward to their Chapter 11. |

The good news is that kind of thing won't happen when we're all driving/riding electric cars because there's no head. If the motor fails, you just bolt on another one and rebuild the old one. Life will be good again. |
