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.

Consumer complained about a fuel injection system problem. There was 50,000 miles on the vehicle, and it was no longer under warranty. The defect was the result of poor gas that was used in Arizona. Consumer had the fuel injectors cleaned and flushed. Several weeks later the problem recurred.

  • Automatic transmission

Engine check light started flashing on dashboard. Consumer parked vehicle, and dealership determined that 5th fuel injector was defective, and a spark plug was inoperative. On second occurrence, while traveling at approximately 50 mph, engine started misfiring, and engine check light came on. Then, engine suddenly died, causing consumer to lose power steering capabilities. Dealership examined vehicle, and found 4th fuel injector to be defective. Had to change oil because fuel leaked into T crank case.

The claim by the dealer performing the repairs is not the dealer the car was purchased from. The dealer is nick abraham Chrysler Buick Jeep,1111 E. broad St. Elyria, OH44035. The car continues to have a miss in idle, and periodically loses power while driving. The dealer stated that the fuel injectors are fouling out or becoming dirty due to a chemical contamination, not dirt or foreign matter bypassing the fuel filter. The gasoline used in this vehicle is shell 87 octane or sunoco 87 octane. A higher octane (89) has been used and the same problem has occured. If it is a chemical contamination causing the injectors to continue to foul out, I would suspect it to be from the fuel reacting with the fuel system components and causing repeated trips to the dealer only to be met with the same results of being told that they cannot find the problem. Please advise oon how to correct this problem once and for all. Tahnk you.
