There are 1 owner-reported fuel system complaints for the 2018 MINI Countrymanin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Fuel sensor failed and due to tank pressure that would not release properly, according to repair shop. Among other safety issues, this caused me to not be able to open the gas tank to refill the gas tank. This has been ongoing. At first the gas flap was repaired (2x) and ultimately the fuel sensor was entirely replaced at my cost. All repairs were done at New Country Mini in Hartford, CT. The repair shop should provide history of repairs over the several years as Mini is denying the seriousness of the defect. I’ve notified mini.
