“I recently took my Chevrolet Colorado in to a Chevrolet dealership because my check engine light was on. It was diagnosed that a sensor on the gas tank was rusted and needed to be replaced. The service manager admitted this was common for a Colorado. Parts were ordered and I was told it would cost about $800 to fix. I brought my truck in a few days later to have the work done. Later that day I was called and asked to come in because they found another problem with my truck that I needed to see. …”

“While driving the vech. Once it goes under 10mph it will stall out. I then have to put it in n and restart. This has been going on for a while. Ever since it about 40-45,000 miles...I have not been able to afford to pay to have it fixed. I was told by a chevy dealer service manager that it has a faulty coil system and chevy does know about it but when they choose to issue a recall notice is there choice.”

“I bought a 2004 Colorado in march of that year,on dec. 31st 2004 I had to replace the two front tires at my expense. They had worn from the inside out the tires had 23,000 +miles on them. I complained to the dealer and they told me that there was not anything wrong. In march 2005 I had to bring it in for the same thing with less miles on those tires 17,000 miles and they still insist that there is nothing wrong. I soon will have to replace these tires before winter. The dealer tells me tires need to be rotated more often. …”

“My 2004 Chevrolet Colorado has had repeated a recurring problem where it will not respond to the throttle at all while driving. In all cases this has happened when the engine is warming up from a complete cold start in the morning. While driving at 45-50 miles per hour the engine will drop to idle speed and there is no response to throttle input. The dealer has had the vehicle in for service on this issue 5 times now and can nothing wrong. There are no codes set in the computer and the check engine light never comes on. …”
