One problem related to catalytic convertor has been reported for the 1999 Chevrolet Blazer. The most recently reported issues are listed below.
Many problems were identified to the dealer at the time of purchase. I was told that all items would be corrected. To date about 50% of these have been corrected after many attempts by me to get satisfaction with the dealer. I have attempted to contact the manufacturer but have been unsuccessful in my attempts to get by their customer satisfaction staffs. They refer me back to the dealer. Many illegal and improper actions were taken by this dealer during and after the time of purchase. My satisfaction and safety are at risk with this vehicle as the rear window assembly does not seat properly. Constant air flow at this window and around the doors is creating an unsafe environment within the vehicle. I believe that carbon monoxide and carbon dioxide fumes are entering the vehicle at these points. My family finds that they experience severe and numerous headaches, burning eyes, etc. When in the vehicle. It is also creating a noise hazard within the vehicle as the air currents are consistant at all speeds.
