There are 8 owner-reported fuel system complaints for the 2015 MINI Cooperin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The fuel filling nozzle turns off repeatedly while trying to fill the fuel tank and spills out causing a safety and environmental hazard, regardless of the pump being used. As a result, no fuel goes into the gas tank, instead it goes all over the car and the ground.
Fuel tank causes gas pump to click off after dispensing a tenth gallon of gasoline. Gas spills from gas tank while removing pump creating a safety and environmental hazard. Fuel tank will not accept gas at pump. No warning lamps, messages, or symptoms were present prior to the failure. Mini Cooper dealership stated that service valve in tank has failed and entire fuel tank must be replaced.
When refueling, fuel is rejected after dispensing about 1/8 US gallons, about 4 oz. Of course, fuel spills are a hazard - both in possibly of fire, and to the environment - by contaminating ground water. Dealer said that there are several solenoid operated valves and replaced fuel tank and fill pipe, a cost to me of $2400.00. There are many reports of this on social media, one person suggested holding the fuel nozzle upside down which made a larger spill.
The fuel filling nozzle turns off repeatedly while filling the fuel tank, regardless of position of nozzle, pressure used, station used. In an attempt to remedy, Mini Service Technicians replaced tank vent valve but it did not correct the issue. I am unable to fill my gas tank.
I can not put gas into my car. I have had the charcoal canister replaced. I am now being told that I need a new fuel tank. I’ve also been informed that this is a reoccurring problem in 2015 mini coopers.
Fuel tank shuts off the gas pump no matter how much gas is in the tank. Faulty fuel tank vent (purge) value is causing the issue. This is a known issue on Mini's. A voluntary recall has been issued for 2016 Mini's, but this problem is also happening on 2015 Mini's. Dealership as well as another auto service store has replicated the issue. Check engine light is lit up as well.
Unable to fill gas as pump repeatedly shuts-off while trying to fill and would even over flow out of the filler neck. Tried 2 different pumps at local QT without luck.. Drove up to local Phillips 66 with exact same issue. Found several other owner with similar issue and found the following Service Bulletin posted on "NHTSA": https://static.nhtsa.gov/odi/tsbs/2015/MC-10147283-9999.pdf My vehicle build date is not covered under this Service Bulletin, however, suffering exact same issue.
Fuel tank did not allow me to input fuel. Pump clicked off immediately. MINI issued a service bulletin on the problem in 2015. I have been advised the entire fuel tank must be replaced, and have heard from other MINI owners this is a systemic problem. If I had been traveling and this problem had surfaced I would have been stranded. The repairs warrant warranty coverage on the part of MINI. See service bulletin SI M16 01 15. https://static.nhtsa.gov/odi/tsbs/2015/MC-10147283-9999.pdf
