The contact owns a 2007 Nissan Altima. The contact stated that his vehicle needed a catalytic converter. When the converter was replaced, he smelled a potent odor in his garage and must leave the garage door open to release the smell and the vapors. He took the vehicle back to the dealer and they stated that nothing could be done. The vehicle has not been driven since it was purchased on September 20, 2007. The engine size was unknown. The VIN was verified, but appears to be invalid. The failure and current mileages were 2,100.
