: the contact stated the check engine light illuminated constantly when the vehicle was started. The vehicle was taken to a service dealer who determined that there was a crack in the fuel tank.

The check engine came on recently and I took my 1999 Saab 9-5 to the dealer. After several attempts to correct the problem, it was found to be a crack in the fuel tank. The car was stored outside with little gas in the tank while waiting for Saab to locate a new tank. It has taken over 5 weeks and Saab claims no responsibility for the problem. My question is: Have there been other reports of cracked fuel tanks made for Saab cars from 1999 to 2005 which all use the same tank?

Leaking fuel tanks. I have replaced the fuel tank on this vehicle twice. The tank is now leaking again. The leaks cause the check engine light to come on (small evaporate leak code) and occasionally cause fuel vapors in the cabin. The tank is made of plastic, making it impossible to repair - must be replaced. Without replacement, vehicle will fail emissions testing and I fear fire hazard.

(1) due to a manufacturing defect in the design of the car, a hole has developed in the top of the plastic gas tank of 1999 Saab 9-5 sedan. (2) a "smoke test" has revealed the hole in the top of the tank. The car has developed a gas evaporation leak. There are prominent gas fumes and smells in the car's cabin, and the check engine light has come on. (3) this is the second gas tank on the car, the first tank was replaced by a Saab dealership after it failed to pressurize properly, a related issue.
