2011 Ford Flex problems: engine and transmission complaints and recalls
37% of relevant owner complaints on the 2011 Ford Flex are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.
Better than 58% of the 1,790 model years we track (2010–2023).
Does the 2011 Ford Flex have engine problems?
More than most. The pattern is elevated rather than severe. 51 of 144 relevant complaints filed with NHTSA about the 2011 Ford Flex concern the engine, transmission or fuel system (37%), and the largest group is filed under engine (25). For comparison, the 2010 scores 44% and the 2012 scores 27%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
