1. Fuel Leak 2. Fuel leaking in driveway, car has potential to catch fire if driven 3. Suspected leak and odor was reported 4 years ago. Dealer said the recall did not apply to my car. After receiving an email reply back from GMLegalUpdate department indicating they would cover the "fuel line" under special coverage, the dealer looked at the car. Dealer said they couldn't find any leak. Now the leak is very apparent when you start the car. Significant gas leaks onto the ground. After speaking to GM at 866‑790‑5600, GM says that my VIN No does not apply to the special coverage. Now they won't honor the letter. A service bulletin 12191B has been issued for this problem "regardless of the vehicle's age or mileage" but it seems from numerous posts GM pawns this problem off as the car's Vin No does not apply to their vehicle.

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 the federal safety agency of a rust issue of the fuel line where it is clamped near the fuel tank. There is also reports of crack developing at the intank fuel pump connection. ALL Cobalts,G5 's and other variations of this vehicle should be recalled immediately and inspections of the fuel system be reported back to the federal safety agency. Was there a fire? My answer is "NOT YET".

Fuel line leakage - gas leaks out quickly until the tank is empty. The car is undrivable in this condition, which seems to be a hugely common problem with the 2009 pontiac g5. A massive gas leak is a safety concern.
