I own a 2005 Chevy Colorado. It has only 86,000 miles and the head and intake valves and cylinders need to be replaced. I did some research and many people are complaining of the same thing from 2004-2005 models. The total cost for me to fix this is 1,600. GM knows they messed up with the 2004-2005 inlive 5 engines, that why in 2006 they had different intake valves installed. My dealer said that GM told them to fix the valves and seals and springs, but that is not helping the status. So then they were told to replace the head which cost around $800. Could some one please help me with this" I don't see how a company can noticed they did something wrong but not help to fix the problem. I have also heard several stories that the intake manifold cracks on some trucks, who has ever heard of that" I asked 2 people who have worked on cars for over 30 years, they have never heard of that happening. Please advise...........

Car has 93,000 miles. Vehicle would shut off while at a stop light occasionally. Recently, about 2 months ago the truck would not start. Took me about 20 minutes of cranking until it did. It ran fine, I took it to Chevy dealer grand prize Chevrolet here in miami and they changed the fuel pump. In 3 weeks after the fuel pump was changed the car has left me stranded 3 additional times. I just took off again and told them the fuel pump change did not help, it left me stranded 3 times, same problem, car does not start, after about 5 to 10 minutes of cranking it starts as of nothing happened. They can't figure out what the problem is. I am frustrated that one pays 20,000 plus for a car that does not function properly and the Chevy mechanics can't fix. This is not right.

Attempted O to start vehicle and it will not start. Took vehicle to dealer 5 times, and could not find anything wrong with it. Waited about 10-15 minutes then will start. No matter what the temperature was outside had the same problem.
