2008 Cadillac CTS: fuel pump failure

Filed Feb 16, 2022 · Fuel system · PA

Fuel supply stops and engine stalls when I get near or below 1/4 tank. I can restart the engine and it will run for anywhere from a few seconds to sometimes a minute, but mostly only a few seconds. Limp my car this way to a gas station, fill the tank, problem solved. I know it had fuel in the tank as it only took 11 gallons with my 16 gallon tank. Installed a new fuel pump, problem continues. This can put someone in a life threatening situation. The first time it happened I was passing a semi truck on a 2 lane Interstate with cars and trucks behind me. Just as I got half way on the semi's left, I'm doing about 70 mph, the engine stalls. Luckily, I kept a cool head and turned on my blinker as the car slowed down. The semi behind me took a hint and backed off so I could coast to the right shoulder. This could very easily have caused a fatal accident. It has since happened 3 or 4 other times.

The fuel pump fuel feed line has developed a leak and is spraying fuel creating a fire hazzard. On top of the tank sits the fuel pump. On the fuel pump the feed tube connects to the fuel line which then goes to the engine. This leak created a fuel odor and got progressively worse. I found dampness on top of the tank, which was gasoline. Upon my further investigation I noticed the fuel spraying out of a pin hole sized crack. This is similar to a recall issued on other gm vehicles in the past and I feel the cadillac cts should be included. I've notice other people having the same issues via an online search at cadillac web forums. I performed the repair myself but it is a very labor intensive and expensive repair for a non capable person if done by a dealer or repair shop. We are talking about a 6 hour job because the rear frame, differential, exhaust etc must be removed to access the gas tank. A major issue and safety risk in my view. The leak will occur whenever the car is on as well as off since the fuel system is under pressure. When car was parked - my garage smelled like gas the leak was so bad. ** I have photos and video and will upload at a later time. ** this car is a perfectly maintained vehicle and still appears brand new - no abuse or other issues caused this defect in the fuel pump module.

Car w/ 95,000 miles. Problems at 15,000 miles. Airbag sensors faulty. "ECM" (engine control module) replaced but no issues with how the car was running. Told by the dealership "alot" of ECM's are replaced. Is ECM failure common in this vehicle or is it the dealership replacing ECM's that do not need repair to make money? Ecm was a $1,000.00 repair to fix a gas smell from the car. New ECM and gas smell is still there. Then told now faulty fuel pump and leak in the fuel line as reason for gas smell. Both dealer and gm have refused refund for replacing ECM that did not have to be replaced. Replacing ECM did not fix the gas smell! Prior to "ECM " all six of the oxygen sensors also replaced. Another costly repair. I have pampered this vehicle since I have purchased it from factory. Very suspicious so many issues needing repair have occurred with this car. Now, ignition switch is being recalled and will need repair. I am left driving my family around in a potentially dangerous car. Will my family be the next victim of a faulty gm ignition switch? Also the door locks in the rear of the car are faulty ever since I have had the car. The rear door locks jam and the doors won't open from the outside. The dealer in the first three months replaced one rear door lock mechanism. Before I realized my warranty expired the other rear door lock also had the same problem. Gm refuses to fix it. Now an expense of > $400. Having an infant who rides in the back this is concerning that rear door lock jams. Repairs on this 2008 cadillac cts are endless and should not have to be so numerous considering I have been the single owner of this vehicle and have kept the vehicle very well maintained. I would like to know if other owners of this make and model of vehicle have had similar problems? Is there a manufacturing issue??

Car was towed to dealer. Repairs findings included a melted fuel pump harness and fuel pump inoperative as a result. I feel under certain circumstances the results could have been catastrophic resulting in damage, injury, or possible death.

Strong smell of gasoline was coming from rear of vehicle. Upon inspection, a crack and leak in the plastic supply line of the fuel pump module was found. This caused fuel to spill and settle on top of the fuel tank which results in a dangerous condition and possible fire hazard. This is similar to a previous recall (12v459000) on 2007, 2008, 2009 gm vehicles that did not include cadillac.

Dealer doesn't know what the problem is. Just waiting for a solution. This is a major safety concern that needs immediate attention.

While driving my 2008 cts, with no advance notice, the engine just died. It seemed to run out of gas. My fuel gauge read between 1/2 to 3/4 full. This happened 3 different occasions. All 3 times I had to have it towed back to the dealership that I purchased the car from. All 3 times I got different reasons it happened, from bad fuel pump in gas tank, to some type of bad connection, etc. After this happened the 3rd time, I demanded a new car, which I received. I have had no problems with this cts, runs great.
