I started experiencing a strong smell of gasoline while driving and when the vehicles was shut down. When I first noticed the odor I could not see any visible leaks under the vehicle, after about a week I started noticing drips of fuel under the vehicle. I crawled under the vehicle to find the leak and noticed a very fine spray of gasoline coming from the top of the tank. I then dropped the fuel tank and noticed that tube from the fuel pump was corroded to the point that it was spraying gasoline while under pressure. The fuel pump is located in a low point on the top of the tank which allows for road debris/salt and water to sit and erode these tubes on the top of the fuel pump. This is a very dangerous problem as all it would take is any form of ignition to cause an uncontrollable fire. Gm should be required to repair this under a mandated recall due to the severity of this problem.

Fuel leak coming from top of gas tank. I suspect it is the fuel pump module. Severe rust and limited visibility prevented me from identifying 100 percent. Talked to gm, they know of the problem but since it happened 14,000 miles beyond their extended special warranty for this, they will do nothing. Bad design is a bad design regardless of miles or years. Very dangerous having a leak this bad. Will fix myself when I come up with the money.

I took my vehicle to the gmc dealership because of a distinct gas odor by the vehicle. I had previously received a cautionary letter from gmc that there could be a problem with the fuel pump involving pooling and pitting and extending the warranty to ten years to correct the defect. The inspection at the dealership stated that there was a "fuel leak from the top of the fuel tank area-fuel pump module leaking" the service advisor was sufficiently concerned to offer me a replacement vehicle to drive until the repair was made. He said that if I were to hit something and create a spark I could be in jeopardy. I was also concerned about a stray cigarette butt thrown out a window. He also gave me the customer assurance telephone number to call to file a claim. I did call the next morning and information was given and I was given a case number and told that the "district " would call me. When I received the call from that office she told me they would call me the following day. Ten minutes later she called back and said that gm would not offer any assistance. They obviously knew there was a potential problem or they would not have sent out warning letters. I believe it should have been a recall considering the potential hazards involved. I wonder how many people did not read the letter and subsequently had repairs made at their own expense so they never reported the problem. It was a costly repair and I feel they should have covered the expense. I count myself lucky that it is not my serviving family filing this complaint.

Check engine light illuminated on instrument cluster. Diagnostics indicated a code po 442. This code is indicative of a fuel system leak in the evaporative emission system. Replaced gas cap. Problem not resolved. Filled vehicle with gasoline in october 2010 and several times since. Strong odor of gasoline is present. Each time fuel nozzle fails to shut off fuel from gasoline pump and gasoline is spilled on the ground near passenger side rear door creating an environmental and major safety hazard. Vehicle never in accident or modified in any way. Vehicle has 62,000 miles. A courtesy general motors repair program is in place for these vehicles if the long wheelbase models. Numerous occurrences in the short wheelbase models also. This is a known defect according to the gm dealer that services the vehicle, but they want over $1500 to replace the fuel tank and the tank unit which includes the fuel pump, gauge, and hose connections. There is no guarantee this will fix the diagnostic code that sets the check engine lamp, or the problem of gasoline leakage/spillage. The vehicle will not pass a state safety inspection and therefore is not allowed on the road. A forced recall should absolutely be made for these vehicles. At a cost of over $35,000 for this vehicle, and the hazards it represents, it is a total travesty that gm refuses to stand behind their product.
