The 2018MINICOOPER carries 10 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 5 crashes, 0 fires, 6 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2018 COOPER is air bags with 2 filings, followed by unknown or other (2) and electrical system (2). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 6 investigation files overlapping the 2018 COOPER. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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.

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 appea

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.
