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.

1998 Jeep Grand Cherokee Owner Comments

problem #1

Jan 122005

Grand Cherokee 4WD 8-cyl

  • Automatic transmission
  • 39,000 miles


I own a 1998 Jeep Grand Cherokee limited 5.9 liter engine. I drive the car 5000 miles/year and the car has 39000 total miles. The catalytic converter failed and began to rattle. The local Jeep dealership refused to admit it was the catalytic converter, and said it was the muffler. I took the vehicle to 4 different exhaust shops, and all 4 immediately said it was definitely the catalytic converter. I finally got the Jeep dealership to replace it and they too finally admitted it was indeed the catalytic converter. While I have been dealing with this issue I did much research on this cars catalytic converter. I found many websites with owners of my same car and other similar Chrysler cars that use the same catalytic converter. Every owner that wrote complaints described exactly what my problem has been. They all said that their catalytic converter has broken from between 8000 miles, the average seemed to be 44000 miles, and had to be replaced on average 3 times before 100000 miles. There is obviously a problem with this epa required exhaust part that the manufacturer has been using. Please look into this issue.
