Noticed a strong gas smell coming from rear of car for several days. Finally took car in for inspection. Mechanic said that the fuel pump modulator needs to be replaced. I've seen on several websites that the pontiac g5 has the same problem and were being recalled. Unfortunately I haven't seen anything about the pontiac g6. I believe that this is a serious issue with this car. Could you please investigate this. When parking the car in my garage the odor was quite strong and also a danger to me and my family. The car could have caught on fire as well as my house.
