NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2018 MINI Cooper. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
My 2018 Mini Convertible has 47,000 miles on it. Recently the convertible top stopped retracting and now doesn't fit snuggly when closed. I brought my car into the dealer and they said that a cable broke and gave me a repair quote of $4600-. I sent a msg to Mini USA and they called me and said they would cover the repair if it breakage wasn't due to something I did improperly. About a week later they called back and stated that they would not cover the repair because the warranty had expired. They definitely mislead me on the initial call. My car no longer operates as a convertible, and I have excessive wind noise in the car. I feel like a car with 47,000 miles on it should not be experiencing such expensive repairs. I shared my experience on social media and apparently many others are having similar experiences. I am considering trading my car in for a different model as Mini Cooper does not stand behind their products.
Tire size 205/45 r17 pirelli ginturato We were driving from an appt and the low tire air light came on. We got to car x and found the side wall and tread belt on the inside of the tire had came off. Car x didn't have a replacement tire and they switched the bad tire to the back so we would have xontrol of the steering in a blow out they said to go across the street to Goodyear but be careful. Goodyear had to good get a tire because the car was considered unsafe and a road hazard to drive on the road or highway. We were over an hour from home. The other 3 tires are doing the same thing.we don't have the tire but we do have pictures. Our car could have cause a big accident if we hadn't thought quick enough and the mechanic hadn't found the problem I'm not sure if others have had this issue but the other 3 of our tires are doing the same thing. The car is inoperable until we can afford 3 more new tires. The vehicle was inspected by 3 mechanic... car x, Goodyear, and my husband.they appeared the same day. There was no symptoms except at the last minute the low tire air light coming on.

Driving at low speed piercing loud noises came from speakers, buzzing and whining. Noise stayed on with ignition on or off and radio on or off. This occurred two more times on way home. Am waiting for dealer appointment. Have not driven vehicle since.
Took car into mini dealer for clunking noise problem. Dealer indicated motor mounts were cracked and needed to be replaced. Another customer at dealer was also having motor mounts replaced. His car was also 4 yrs old with 32K miles on it. Mount replacement was not covered under warranty as the car was 4 yrs and 3 months since warranty was activated and coverage ended at 4 yrs.
