Example complaints

Fuel system: “Fuel pump module failed twice. There was no warning lamps, messages or other symptoms prior to the failure. The first time I was driving the second time the car was parked and did not start. See below for details. Safety: Thankfully i was not driving 70+MPH down a busy highway when the car shut down. Given the past recall, the number of Cadillac owners experiencing the problem and that it's happened to me TWICE within three years, it's only a matter of time before serious injury or death occurs. …”

The issues began about three weeks after my lease began. Cadillac directly and the dealerships have done nothing to resolve this and have continuously kicked it down the road with no resolution. I am not comfortable driving a vehicle in which seatbelt deatures are compromised.”
