2008 Cadillac CTS: engine stalls while driving

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 vehicle will stall while cruising to a stop light, while at idle and sometime while accelerating. I've read a lot of posts online about this issue but no one has a solution. I got stranded on the highway in the middle lane once too. Gm will not do anything about it. The vehicle is in the shop right now and my diagnosis fee its over $750 and there is still no resolution for this issue!!! This issue is an ongoing issue for years now!!!

1. Car stalls/hesitates on right turn. Dealer service could not replicate. Problem started at ownership, and continues at 25k miles. Problem not corrected. 2. Check engine light: car vibrates/shakes standing at idle. 21 days out of service. 3 dealers; four visits. One dealer could not extinguish check engine light. Dealer disassembled engine and made repairs. (exhaust is noticeably louder (not repaired) and the fm radio will not work when the rear defroster is switched on--I suspect a ground wire was broken during the repair (not repaired).

Driving up a hill in pa. We were on state highway 118 near sweet valley pa. Car bucked and jerked violently. Car stopped running in middle of roadway with traffic backed up behind me. Eventually cars worked their way by me and I was able to drift car back to a place where I could get it off the road and out of the way. Very harrowing experience. Very unsafe. Car was towed in as it would not restart. Tow truck driver also tried to restart to move car to optimum place to put car on flatbed. Car would not restart. After diagnosis the dealership said that: car only had 3 gallons of gas in tank and this was not enough to get up hill. Gas gauge showed between 1/8 to 1/4 of tank. No low fuel light. The dealership said that it might not happen again, but that it could. After returning to my home in fl I took it to the selling dealer. They called cadillac and cadillac agreed with both dealerships that there was nothing wrong but that due to the design of the gas tank, the car could stall going up a hill at any time unless a significant amount of gas was in the tank. They would not define significant. They said that gas had sloshed to the rear of the gas tank and the gas pickup was sucking air. They say that after car was towed 30 miles on a flatbed gas sloshed to the front of tank and engine could be started. They said that nothing could be done. This is a very, very unsafe condition. The guy behind us almost hit us as we decelerated rapidly. And then a whole line of cars almost collided. Cadillac says that nothing can be done. I say that something must be done to protect drivers of all 2008 cadillac cts.
