The fuel line broke due to the high side fuel pump seizing up and the break away bolt breaking causing the pump to be unstable. thus the vibration causing the fuel line to brake spewing gas all over. the fuel line breaking then prompts the computer something with fuel is malfunctioning and shuts motor to half running power an throughs some more fuel related codes. rendering your vehicle inoperable and needing a tow to a shop for repairs. the fuel pump design helps save your motor in this event from being destroyed, when it malfunctions like this. the fuel pump design seems like it could be highly dangerous. with fuel be spewed out at high pressure is unsafe. it sounds like the fuel line breaking because of this design is a pretty common problem. i believe the 2018 cadillac has a recall on this exact same thing that happened to my 2013 but the 2013 has no recall on it?? when my vehicle fuel line broke i was driving in normal conditions in motion on city streets. i'm sure there was turning and braking in the midst of the fuel line breaking. the specific part that broke was fuel line part number 12627125 and high side fuel pump part number 12658486.
My vehicle always missing or act like it going to turn off or some time it turn off. it vibrates when you take off. then it stops but when you come to a stop again it does the same thing everytime. and everytime i take it to the shop they always tell me something different to cost me more money. this car is a lemon!!!!!!!!!!! major problems it stays in the shop. i can fax you or give you the dealership number so you can get all the times it been in the shop and all the problems.
