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.

While driving in town around other vehicles namely those with bright lights and at stop lights. It felt as though there was a ton of pressure inside my vehicle almost like the the windows were going to explode. Im not sure how to explain it maybe a gravataional downward pull? Almost like a chemical burn from the brightness of other headilghts and the vehicle mirrors mixed chemical nomenclature were having a bad reaction. This caused me to become aware of an issue. I took the vehicle in and had the battery tested noticing the battery was located in the trunk with no protection surrounding the battery and wires semi exposed placed next to fuses and sheet metal. Who designes things like that? Thats a disaster waiting to happen. Today my head still hurts and I will be seeking a medical professional.

Service air bags shows on dash on startup, bought this way from holz chevy in hales corners, wi. Was told it was a non issue. Electrical- changes from radio to aux randomly, the back speakers work constantly, the driver side never works and the passenger side works on occasion (if you hit a pot hole hard enough it'll go on/off). Fuel- fuel line was leaking from driver side, in front of rear wheel. Right by the heat shield.

My 2008 g5 has a strong gas smell both inside and outside the car. I checked for recalls and saw that 2008 g5's have been recalled for a fuel leak due to a defective fuel pump module but only in hotter states. I'm in sc and we certainly should qualify as a hotter state with temps in the upper 90's in the spring. Gm recalled the '06 and '07 g5's in sc for fuel leaks so they should recall the '08 model too since it has the same problem (recall 09v‑419) my car has only 31,903 miles on it so I should not be stuck with the cost of repairing an ongoing fuel leak problem that gm has had with '06-'08 models. My mother bought this car new from the dealership and it has been garage kept and driven very little. Gm should repair all the 2008 g5's that are leaking fuel, not just the ones in a select few states. Fuel leaks are dangerous and could result in a fire in any state.

Started to smell a strong fuel odor in garage. Noticed about a foot in front of the driver side rear tire dripping gasoline from fuel line next to the plastic clip there. This is very close to the exhaust pipe and very dangerous. Went online and saw several similar complaints about this issue and how there was an associated recall but only for 5-6 states. Not sure why only these states were listed but in line with many of the other complaints the plastic clip holding those fuel lines was holding salt and brine of the winter months and causing corrosion at that spot. Taking the car in to a dealer to have it looked at and am fully expecting to have to replace the whole fuel line at $600-1000 similarly to the other complaints I saw. If this issue was already recalled for some states then it needs to be recalled for all of them as it is clearly an ongoing and persistent issue.

Car speeds up without pressing the gas petal and it's hard to stop it when in motion on interstate it stopped out of nowhere and turned off with an 18 wheeler behind me like to have killed me got car in neutral finally forcefully praying that jesus protect me because it would not shift into gear and pulled over to side of road. I'm scared to drive my car. Driving down road steering wheel locks up causes engine to shake whole car and backfires my car rides really rough. Messed up power steering has caused my blinkers not to work now. I'm really sad. The engine light comes on every time I put gas in my car. The transmission acts up and when driving my car it's like it doesn't know what gear it should be in so it jerks really bad.
