Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Cooper Countryman.
The 2018 Mini Cooper Countryman sits on Mini’s compact crossover platform and is powered by a gasoline engine that uses 4.5 qt of 0W‑20 oil, mated to an S6 automatic transmission, delivering an EPA‑rated 24 mpg city, 32 mpg highway and 27 mpg combined fuel economy. Its modest mechanical layout is complemented by a clean record of zero recalls and only six owner complaints, the bulk of which involve the electrical system rather than powertrain durability. Compared with the broader model line’s complaint history—peaking at 118 reports in 2012 and falling to a low of 18 in 2016—this 2018 iteration benefits from the trend toward greater reliability, positioning it as one of the more dependable years in the Countryman’s lifecycle.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The first-generation Countryman (2011–2016) showed a clear arc: complaints peaked in 2012 at 118, then recalls and investigations spiked in 2014–2015 (7 recalls, 2 investigations) before settling to just 18 complaints and 1 recall in the final 2016 model year. The 2018 model belongs to the second generation, and the provided federal data for that year is limited to top complaint areas, showing only 2 electrical, 1 engine, 1 service brake, and 1 air bag/structure issue, with 3 crash complaints and no fires. This low complaint volume suggests the 2018 Countryman avoided the early-generation troubles seen in the 2011–2016 run, though direct comparison is constrained because total complaint counts, recalls, and TSBs for 2018 are not given. Based on the available data, the 2018 model year appears to be a relatively clean choice with minimal reported problems, making it a potentially good buy.
