Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 640i xDrive.
The 2014 BMW 640i xDrive is a passenger car paired with an eight-speed automatic (S8) and EPA-rated at 20/29/23 mpg, while its oil service calls for 6.8 quarts of 0W-30, 0W-40, or 5W-30. Reliability records for this model year are comparatively light: only seven owner complaints have been logged, with structure cited as the top area, and no recalls issued. That combination of minimal complaints and zero recalls places the 2014 640i xDrive among the calmer chapters in the model's reliability history, meaning it does not stand out as a trouble-prone year.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
In 2014 the BMW 640i xDrive recorded 7 complaints, 0 recalls, 1 investigation and 308 technical service bulletins. The following year, 2015, saw complaints drop to 4, recalls rise to 1, investigations remain at 1 and tsbs fall to 253. Complaint areas for 2014 were led by Structure (2), Engine (1), Unknown Or Other (1) and Air Bags (1), with 2 crash‑related complaints and no fire complaints. The trend shows declining complaint volume but an increase in recalls from 2014 to 2015, while investigations stayed constant and tsbs decreased. Because the 2014 model has more complaints than the 2015 model and the data does not specify a root cause for those issues, it is less favorable as a purchase unless a thorough pre‑buy inspection is performed.
All 7 complaints on record, top 6 components.
