• The N63 V8 in F10 cars, mainly up to 2013, burns oil through worn valve-stem seals and also suffers broken chain guides, faulty injectors and coolant loss.2010–2013
• On the 2010–2017 F10, inspectors flag springs, dampers and drive shafts more often than average once cars pass eight years, and both generations fail the emissions test too often.2010–2017
