2012 BMW 7 Series: Buy or Avoid?
The 2012 BMW 7 Series, particularly the 750i with its N63 V8 engine, represents a significant reliability gamble for the unprepared buyer. While offering unparalleled luxury and driving dynamics, its complex engineering and well-documented engine and electronic issues mean a deep financial commitment is absolutely required to keep it running properly. This is not a purchase for the faint of heart or the budget-conscious owner.
Unless you are an experienced BMW enthusiast with a substantial repair budget, access to a specialized independent mechanic, and a clear understanding of its common faults, the 2012 BMW 7 Series is simply too high-risk for the average buyer. Its pervasive engine and electrical issues make it an ownership liability,…
Best Model Years
For the F01/F02 generation, the later 2014-2015 models (especially 740i with N55, or 750i with N63TU engine) are marginally better, but the 2012 is squarely in the problematic zone.
Years to Avoid
Absolutely avoid 2009-2013 750i/Li models (N63 engine) unless specific, verified engine remediation has been performed.
Biggest Strengths
- Exceptional ride quality and comfort
- Robust driving dynamics for a large sedan
- Luxurious, high-quality interior materials

Prepare for substantial repairs. Air suspension components are likely to fail, and critical N63 engine issues like severe oil consumption or timing chain stretch become more prevalent. Transmission fluid service is crucial if not done al…
High Risk - Major Overhaul Likely
