Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2005 Chevrolet Colorado Owner Comments

problem #1

Jan 212005

Colorado 4WD 5-cyl

  • Automatic transmission
  • 5,000 miles


I purchased a new 2005 Chevy Colorado in November, 2004. I did my first oil change at about 500 miles. My second oil change was done about 2,000 miles. At that time I noticed oil dripping from the rear portion of the engine. I pulled off a rubber cover on the bottom of the transmission and noticed drips coming from the rear main seal area. I called the deal and they told me to bring it in, which I did. A couple of days later I received call telling me the rear main seal was leaking and they would need to replace it, saying it was a factory assembly error. About 2 weeks later I changed the oil again at about 3,500 miles and noticed oil leaking again from the same area. I called the dealer again and was told doubtful it is the seal again, but to bring it in. Again I got a call saying the seal was in fact leaking again and they would again need to replace it. Now a few weeks later, I went to change the oil at about 4,800 miles on it ( I do change my oil frequently) and sure enough, there was oil dripping from the same area. This time I called the dealer and they said they need to contact Chevy technical support for possible answerss. I still have an oil leak at the rear main seal...
