What owners say
The fuel pump is leaking gas on top of the fuel tank. I just bought the car and didn’t know about the consistent problem with second generation CTS. The problem is stated to ba a plastic elbow attached to the fuel pump that ruptures.There is a fuel smell inside while I’m driving and around the car when the car is motionless. This a fire and explosion hazmats that is common to this model year. I can see some fuel on the side of the fuel tank. From reading , I can see that GM has recalled other vehicles for the same problem. I believe that the first generation CTS was recalled and the second generation was not included. Replacing the fuel pump is a very expensive a labor intensive process and I would like to have 2009 CTS included in the recall.
First ECM module needing to be replaced, we replaced it then after that started running rough, took it to auto zone, 12 codes popped up. Did normal maintenance of vehicle, oil change spark plugs . Then a few days later we were on the highway and all of a sudden we lost all power, pushed on accelerator no power, front end started shaking, so pulled over, vehicle was very hot and smells like gas, had it towed compression test were no good, was told gasket were bad, also was told to check the recall list. Im up set because our children were in the vehicle with us. I hope we are able to get whatever needs to be fixed on this vehicle. Thank you.
Noticed gas smell coming from car. I got worried once the gas smell became a everyday thing. Mechanic states a gas leak is coming from the gas tank area. Did a search online and a lot of petiole are having the same issue with this make and model.
Fuel pump assembly leaks from the plastic "pvc" 90 degree elbow located on the top of the fuel pump. Normal vehicle operation will cause the plastic "pvc" elbow to crack which in turn leads to a pervasive and dangerous fuel leak. The fuel leak then begins to puddle on top of the fuel tank which then flows down the fuel tank towards exhaust and eventually the ground. A strong smell of fuel is present while vehicle is on or off. The leak becomes greater as more fuel is sent to the motor. This is a pervasive issue on many 2009-2015 cts and cts-v vehicles which can be seen on many message boards and forums. This issue has the high potential to cause a fire in which injury or death can occur. In addition, this leak does cause a fuel shortage to the motor affecting drivability of the vehicle. The piece that leaks is inferior and should be replaced to avoid issue. A recall should be issued to resolve this potentially deadly issue.
On any in clining road or acceration of the gas, stalling and power acceleration decreases dramatically.and extremely smell of gas inside the carriage caused nausea, severe migraines, light headness, to me and my too young daughters. Fuel efficiency also decreased...

- What is wrong
- General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured October 6, 2003, to March 15, 2007, and 2006-2007 Cadillac STS-V vehicles manufactured June 23, 2005, to March 15, 2007. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.
- Risk
- If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.
- Remedy
