Car leaks gas toward front of car driver side after it has been running. It also has an odor of gas radiating around the car after it has been run. This car has been recalled for this problem in regionally hot states. GM alan adler said they would repair cars that has the problem outside of the designated states, but Pontiac refuses. See att.

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.

The contact owns a 2008 Pontiac G5. Periodically, the contact noticed an odor of fuel inside the vehicle and the check engine warning indicator illuminated. The contact stated that the odor went away. When the vehicle was taken to an independent mechanic for routine service, the technician diagnosed a fuel leak in an unknown part of the vehicle and recommended that the fuel lines be replaced. The dealer was not called. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 90,915.

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.

Hi! I noticed very strong gas fumes after filling my car with gas. I took the car to the dealer on Friday, September 22, 2017 and had the fuel pump replaced, after filling my car with a tank of gas, I noticed strong fumes in the car. I noticed the fuel needle went from 401 miles to 388. I drove home parked my car in the garage moments later my daughter arrived home and began complaining about the strong gas fumes in the garage and gas leaking underneath my car. I got out of bed went into the garage, then I smelt heavy gas fumes and saw the gas on my garage floor. I backed the car out of the garage and left the garage door open.

Fuel line rusted out causing fuel leakage. The bracket that holds fuel lines also retains salt and brine deposits and is of poor design causing fuel lines to rust through one spot only. It is located a foot in front of rear driver side tire underneath. About a inch away from exhaust. Fuel pours out a steady drop and puddles underneath hot exhaust. This is not the fuel pump recall problem already listed. Repair costs $951.87 at dealership. Looking underneath car all the line was rust free except this fuel bracket area. This is very dangerous to have fuel leaking on to pavement and under hot exhaust. As gas evaporates its fumes could start a fire. A person may drive for many miles without noticing the fuel leaking. The gas fumes enter the inside of car. If a person smokes this could also cause explosion all from poor design and no recall to replace fuel line and bracket. The fuel leak is constant stationary, in motion on street and highway. This is very dangerous.

2008 Pontiac G5, approx. 77,000 miles. Failed annual inspection due to fuel leak in fuel line, drivers side, rear, just in front of tire. Close inspection of fuel line, showed it to be the fuel return line, that had rusted a small hole due to shielding that was around the line in that area retaining moisture (shielding was fiberglass looking in appearance and covered in silver covering and most likely is a heat shield as like are about a foot from the exhaust pipe. This is a poor design as it retains moisture around the line causing it to rust. Dealer estimate to repair (replacing entire fuel line was $700+. this appears to be a common issue with these cars (Chevy and Saturn versions too) suggest dealers recall these cars and replace with stainless fuel lines if lines are rusty.

Noticed a strong fuel smell coming from rear of vehicle after returning from a trip to the store. Looked under vehicle and saw a puddle of fuel forming on drivers side in front of rear tire. Looked at the undercarriage and saw a steady fuel leak coming from the fuel line beneath the silver heat shield wrap. I removed the wrap to find that the fuel line had rusted through around the plastic mounting clip. This is a serious safety defect as the fuel line run inches from the exhaust pipe hence the manufacturers heat shield wrap attempting to shield the fuel lines from the exhaust pipe. This is a poor design as it is located just in front of the driver side rear tire. The heat shield wrap gets saturated from water from the tire then has no place to go, accelerating corrosion. My vehicle only has 63,000 miles. This should never had happened. Request GM correct the design and repair my vehicle thus eliminating future occurrences.

After noticing a gasoline smell and a puddle collecting underneath my vehicle while it was in park, I took it to the dealer to see what was going on with my vehicle. The dealership then informed me that my vehicle was seriously leaking fuel. They told me that the fuel line from the tank to the engine was completely rusted through. The price to replace this part is completely ridiculous and I am highly upset that no one has told me that this part was starting to rust for the last year. My car is only 9 years old and doesn't even have 100,000 miles on it. This is a highly unsafe issue that requires the company to do a recall on because no one should be driving their vehicle when there is a fuel leak!!!!

Noticed a fuel smell in the car, then had trouble starting the car. After a few days there was a puddle of liquid under my car as I left the grocery store. Fuel smell was extremely strong. Got home and looked under car and found a fuel hose leaking gas. Took into a mechanic who found the whole fuel line to be rotted! its a 7 year old car with slightly over 100,000 miles on it. Mechanic said he has never seen anything like this and can't believe their isn't a recall issued on this. This is very unsafe and could have seriously harmed myself and my children had a fire started.

When we fill up the fuel tank the car has a very strong smell of gas inside the car and several feet away from the car and found a puddle of gas under the car. Once the tank is 1/2 down the smell subsides. We took it to the dealer and they said we needed a new gas tank, lines and pump.and seal. The car is only 7 years old with 40,000 miles on it. There isn't any physical damage to the tank and we feel that it ahould be taken care of by the manufacturer as it seems to be an error in the assembly of the tank. Thank you for your time.

We smelled a strong odor of gasoline after parking the car. We continued running errands (stop and go driving) and the smell continued. We then parked the car until the following week because we were afraid to drive it. Upon taking it to a mechanic, he informed us that the plastic return line from the fuel sending unit/fuel pump was severely cracked and leaking gasoline on top of the fuel tank underneath the car. He removed the fuel tank and replaced the entire sending unit/pump with a new unit from GM. He stated several times that the car was not safe to drive before the repair due to the leakage of raw gasoline on top of the tank around many electrical components.
