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.

2003 Chevrolet Tahoe Owner Comments

problem #3

May 152008


  • 35,015 miles


A scheduled oil change on my 2003 Chevy Tahoe revealed broken metal pieces. Cormier Chevrolet who is my service/purchase dealer determined that the debris came from 3 broken rocker arms. Cormier made the necessary repairs under warranty, however, 3 months later the same problem manifested itself again. This time cormier replaced all 16 rocker arms, but I had to pay a $100 deductible. I feel the necessary repairs were caused by defective assembly and/or parts. Especially when my vehicle is driven 98% of the time on local roads only, and has just 35,015 total miles and was purchased brand new.

When starting the vehicle, check engine light comes on and dash says reduced engine power. Vehicle will only drive about 15 miles per hour. Upon researching this through various internet websites, this same problem has and is happening to a huge amount of 2003 Tahoe owner's and it's always a faulty wiring harness problem - yet GM refuses to acknowledge there is a problem. On a side note, headlights have always been very dim.

Vehicle experienced a total immediate loss of power while driving. Almost rear ended another vehicle at a high speed twice during the last break down on a busy highway. The consumer was very dissatisfied with the dealership help in assisting with vehicle. Please investigate
