Defect
On certain vehicles, the evaporative emission control systems may apply excessive vacuum to the fuel tanks during the canister purge cycle. Minor fuel tank distortion could result. A small crack could develop on the upper fuel tank surface. The "Check Engine" light would then illuminate and, in some cases, the vehicle driver could notice a gasoline odor. Fuel leakage in the presence of an ignition source can result in a fire.
Safety Risk
No risk description available.
Remedy
Dealers will pressure check the vehicle's fuel tank to determine if it has cracked. If it is cracked, a new fuel tank will be installed. A new fuel filler cap that decreases the amount of vacuum inside the fuel tank will also be installed.
