Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Strong smell of gasoline was coming from the car while driving and while stationary. Took car to be checked out and learned that a crack and leak was in the plastic supply line of the fuel pump module. This caused fuel to spill and settle on top of the fuel tank which created a dangerous condition and possible fire.”
NHTSA complaint #10781172, filed 2015-10, 105,000 miles“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.”
NHTSA complaint #11252307, filed 2019-08, 80,000 miles“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. …”
NHTSA complaint #11165273, filed 2019-01, 50,000 miles“Cadillac CTS, 2009 model year. Placed the car in park and tried to turn the ignition off. Key would not turn to off position. Engine kept running. Key could not be removed from the ignition. The service technician said that he has encountered similar occurrence with many 2009, 2010 CTS vehicles. My father disabled the engine by removing the fuel pump fuse located in the rear trunk of the vehicle. The car was towed to a Cadillac dealer for repair. This is a dangerous circumstance. If there were an engine fire, one could not turn-off the motor and fuel would feed an engine fire.”
NHTSA complaint #10352577, filed 2010-08, 17,948 miles“My 2009 has 112,000 miles on it. Over a period of time we started to smell gasoline . Thought it may be simply from putting gas in the car. The smell got stronger. Fortunately we had to have a tire replaced. The tire service owner advised we had a major gas leak and advised us not to drive it far. End result was we had a fuel feed pipe that was leaking. Please know we had been driving our 4 year old nephew and 1 year old niece in the car. Final bill was over $2300. Leaking gas !! How can that not warrant a safety recall? …”
