2010 Buick Enclave fuel system problems

Filed Oct 22, 2025 · Engine, Fuel system · CA

The engine and fuel pump system failed while driving the vehicle. It is available upon request to inspect. I just towed it to the shop today on 10/22/25 to get a full inspection. My sister and I were put at risk while driving towards a hill in San Francisco. It was on a busy main road when suddenly the vehicle began to jerk and thud back and forth. While I pushed the gas pedal, I began to question why the vehicle was suddenly reacting this way. In efforts to pull over to the side, a huge smoke fog began to come out of the exhaust pipe. As I tried to reach the curb the car didn’t want to move any further as I pushed on the gas. I put it in park and called the tow truck (receipts below) while there were cars passing me by almost causing an accident. I have looked online to see if there was a problem or recall with this vehicle having the same issue I was having. Come to find out there was a recall issued for certain vehicles only, with the same issue as my vehicle. The vehicle was taken into a local auto shop, where they diagnosed it and inspected it. The reports show it has the same exact issues with the car as those that were recalled. No there were not any warning signs nor failure signals. Due to this reason, I was completely caught off guard.

I was driving at 75 MPH and my engine shut off; car began to slow, fuel dropped, power steering went out, brakes didn't work. I was able to, thankfully, get to the side of the road safely and use the rumble strips to slow me down. I turned the car off and 5 min. Later turned it on and was able to drive to a safe location. This is a common issue and all of these conditions are related to the "limited warranty protection" that gm issued nov. 2015 (14582). This is a safety hazard. My car experienced all the other condition, malfunction indicator light came on multiple times ( may, sept), was issued a letter in nov. 2015 and then this occurred in jan. 2016. Stipulation for this to be covered, under 120k miles of 10 years whichever first. My car experienced initial troubles at 110k in may and this potential fatal incident at 125. Arguing with gm over this. Should be a recall, not a limited warranty. Seems to be an unethical company. Does it take death to make this right? This has occurred countlesss times- check the internet, 100s of customers have reported this. Does this have to be another toyota incident for gm to recognize this is a recall not a limited warranty! I have all paperwork showing the issues except dealer states since they can't replicate, they need the check engine light on and the car to be under 120k to determine if they should pay. Gm is unethical!!!

Check engine light went on. Car was seemingly working alright, however, after fueling up, it was difficult to restart the car. In fact, at the last fill up I was unable to start the car for over 20 minutes while at the gas pump. This caused a great deal of anger, frustration, and rage in the other drivers who were waiting to fuel their cars at very busy gas station near lax. The dealership stated the fuel sensors needed to be replaced at a total cost of $1700.00. Two months prior the air conditioner/heater required repair as a hose needed to be replaced due to a leak, a $425 repair, furthermore, the steering problem we seemingly had corrected 3 years ago is occurring again and is need of another repair. And lastly, 50% of the time when I turn off the engine and pull the key out of the car, the engine continues to run. The occurred around 80-85,000 miles.

When accelerating to enter a highway, the transmission seems to slip. The gas pedal drops to the floor and the engine loses all power. On several occasions the accelerator has stuck and the car accelerates or the rpms increase while I am braking. These issues have been happening intermittently and have been happening since 29,000. Car now has 69,000 miles.
