My 2009 Pontiac G5 was driven to work this morning 6-10-21and parked in a Michigan State vehicle garage. Security notified me at work that my vehicle had a puddle of gas under and near a rear tire. I removed vehicle frome parking garage and parked it in a remote open parking lot. A gas leak in a car is dangerous, and a safety issue for me and others , especially in a parking garage!!! The vehicle has always been maintained as I am the original owner of the car. The car will be delivered to the dealer for inspection on 6/14/21. There are no recalls on this car . Opon my own investigation after the incident, there are numerous complaints logged into NHTSA of a rust issue of the fuel line where it is clamped near the fuel tank.

Gas is leaking (fairly steady flow) near rear driver-side tire when engine is running, in park or drive, stops leaking once car is off. This appears like it should be covered by #12191b, but according to GM my VIN is not in system as being covered. GM will not cover unless I take care in for diagnostics. I wont take car in for diagnostics since it could catch fire until I know that it will be covered. Vehicle has a little over 100K miles.

Vehicle stationary - experienced a hard start post driving, after driving I smelled a strong gasoline vapor. Based on the symptoms and the make, model, year, this appears to be a fuel leak of some sort caused by a deteriorating plastic tube in the fuel line which should be covered by recall https://www.usatoday.com/story/money/cars/2012/09/29/general-motors-recall/1602747/
