The best BMW 7 Series years are 2019 through 2022. These models feature the reliable B58 inline-six engine and updated electronics. We recommend avoiding 2002 through 2005 and 2009 through 2012 due to severe V8 engine failures and costly electrical defects.
Rankings are comparative, and no luxury flagship is flawless. High maintenance costs are expected across all generations. A thorough pre-purchase inspection and complete service history are essential before buying any used 7 Series.
Reliability varies significantly by engine configuration. The inline-six models are generally much more dependable than the twin-turbo V8s. Hybrid variants also introduce complex high-voltage systems that require specialized diagnostic equipment.

How We Evaluated the BMW 7 Series Model Years
Our analysis reviews official NHTSA recalls, manufacturer service campaigns, and technical service bulletins. We also examine consumer complaint patterns and long-term ownership data to identify recurring defects.
Complaints are not confirmed failure rates, and a recall does not automatically make a vehicle unreliable. We separate powertrain configurations, as the inline-six and V8 engines have vastly different reliability profiles.
Recent model years have limited road exposure, making long-term conclusions difficult. Our verdicts highlight comparatively stronger years rather than guaranteeing a flawless ownership experience.
Best BMW 7 Series Years
2019-2022: Best Choice
The 2019 through 2022 models represent the pinnacle of the G11 generation. The 740i features the B58 turbocharged inline-six, which is widely regarded as one of the most reliable modern BMW engines.
These later years benefit from updated infotainment systems and resolved early-production cooling system concerns. While the 750i V8 is improved, the inline-six remains the smartest choice for long-term dependability.
2013-2015: Good With Inspection
The final years of the F01 generation received the updated N63TU V8 engine. This revision addressed some of the most severe oil consumption and timing chain issues found in earlier models.
Buyers must verify that major preventative maintenance was performed. Inspect the vehicle for battery drain issues and ensure the valve stem seals are not leaking oil into the combustion chambers.
Best BMW 7 Series Year by Buyer Type
Best Overall: 2021 BMW 740i
The 2021 740i pairs the proven B58 inline-six with mature G11 chassis electronics. It offers modern luxury without the extreme financial risk associated with the twin-turbo V8 configurations.
Best Budget Option: 2008 BMW 750Li
The 2008 model benefits from late-generation E65 updates. It is a viable budget choice only if the coolant transfer pipe and timing chain guides have been proactively replaced.
Years to Approach Carefully
2016-2018: Approach Carefully
The initial G11 production years introduced a new platform with complex air suspension and cooling systems. Early models experienced water pump failures and expansion tank cracks.
These issues are generally manageable but require immediate attention to prevent engine overheating. Verify that the cooling system components have been updated or replaced under warranty.
2006-2008: Approach Carefully
While better than the disastrous 2002 launch, these E65 models still carry the N62 V8. The plastic coolant transfer pipes inside the engine valley are prone to sudden, catastrophic cracking.
Electrical gremlins and aging air suspension components also remain prevalent. Only consider these years if comprehensive service records prove the major V8 flaws were addressed.
Worst BMW 7 Series Years
2009-2012: Avoid
The early F01 generation introduced the N63 twin-turbo V8, which suffers from severe internal defects. Timing chain guides deteriorate prematurely, sending plastic debris into the oil pan and destroying the engine.
These models also experience extreme oil consumption and rod bearing failures. Repair costs frequently exceed the vehicle’s actual market value, making them a massive financial liability.
2002-2005: Avoid
The inaugural E65 years are notorious for the original iDrive system crashes and complex electrical network failures. The early N62 V8 engines suffer from valve stem seal degradation and timing chain guide wear.
Diagnosing electrical faults requires specialized dealership equipment. The sheer volume of potential failures makes these early flagship models strictly off-limits for most used car buyers.
BMW 7 Series Reliability by Generation
Fourth Generation (E65/E66: 2002-2008)
This generation introduced radical styling and the controversial iDrive interface. While the 2006 refresh improved software stability, the underlying V8 engines remain highly complex and expensive to maintain.
Fifth Generation (F01/F02: 2009-2015)
The F01 chassis improved driving dynamics but introduced the deeply flawed early N63 V8. The 2013 refresh brought necessary engine revisions, making late-production examples significantly safer purchases.
Sixth Generation (G11/G12: 2016-2022)
Carbon-core construction and advanced driver aids define this era. The introduction of the B58 inline-six in the 740i dramatically improved the lineup’s overall reliability reputation compared to previous V8-heavy generations.
Seventh Generation (G70: 2023-Present)
The current generation features massive screens and advanced electrification. Long-term durability data for the new powertrains and complex interior electronics remains unavailable at this time.
Common BMW 7 Series Problems
V8 Timing Chain Failures
The N62 and early N63 V8 engines use plastic timing chain guides that become brittle and break. Debris clogs the oil pickup screen, leading to sudden oil starvation and complete engine seizure.
Coolant Transfer Pipe Leaks
Early V8 models feature a plastic coolant pipe buried deep in the engine valley. When it cracks, coolant leaks directly onto the engine and transmission, requiring engine removal for a proper repair.
Air Suspension Failures
Most 7 Series models use adaptive air suspension to maintain ride quality. The air struts and compressors frequently fail as the vehicles age, resulting in a sagging corner and expensive replacement bills.
What to Check Before Buying a Used BMW 7 Series
- Verify the VIN for any open NHTSA recalls or unresolved manufacturer service campaigns.
- Inspect the engine valley for crusty coolant residue indicating a failing transfer pipe or gasket.
- Review service records for premature timing chain guide replacements on all V8 configurations.
- Test the air suspension by raising and lowering the vehicle to listen for weak compressors.
- Scan the vehicle for hidden electronic control module fault codes using a BMW-specific diagnostic tool.
- Check the battery health and registration history to prevent parasitic drain issues.
- Arrange an independent pre-purchase inspection with a technician experienced in German luxury vehicles.

Are BMW 7 Series expensive to maintain?
Yes. As a flagship luxury vehicle, the 7 Series requires premium parts, specialized diagnostic tools, and frequent preventative maintenance, resulting in high annual ownership costs.
Which 7 Series years have timing chain issues?
The 2002-2008 N62 V8 and the 2009-2012 N63 V8 engines are notorious for premature timing chain guide failures that can destroy the engine.
Is the BMW 740i better than the 750i?
For used buyers, the 740i is generally the better choice. Its inline-six engine avoids the severe oil consumption and timing chain issues that plague the twin-turbo V8 750i models.
Do all 7 Series models have air suspension?
Most modern 7 Series vehicles feature standard or optional adaptive air suspension. The air struts and compressors are wear items that typically require replacement after 80,000 miles.
Should I buy a used BMW 7 Series with a V8?
Only buy a used V8 model if it has extensive service records proving major preventative maintenance was completed. Otherwise, the inline-six configurations are much safer financial decisions.
Which BMW 7 Series Year Should You Buy?
The 2019 through 2022 models represent the strongest choices for used buyers. The 740i inline-six configuration provides modern flagship luxury without the extreme mechanical liabilities of the V8 engines.
Buyers must strictly avoid the 2002-2005 and 2009-2012 model years due to catastrophic engine design flaws. Always verify the VIN for open recalls and secure an independent inspection before purchasing.
