Fuel/propulsion system
4 reports
“The fuel tank was leaking a substantial amount of fuel. Yes it is. Our safety was put at risk due to the fuel leak. Any small spark, overheating or if somebody threw a cigarette butt out of their window could have ignited our car. BMW informed me to immediately cease driving the car and bring to the dealership right away. Problem was confirmed by dealership as stated on the attached invoice. No, no warning or indicator lights were present.”
