According to Au7o's analysis of 0+ owner reports, the 2013 BMW M6 has 2 documented known issues, with 1 rated critical. The most serious is Rod Bearing Premature Wear (S65/S63 Engines) ($3,000-$6,000 repair). Across all issues, repair costs range from $3,000 to $7,000. DIY maintenance guides at au7o.io.
All 2 Known Issues
On the 2005-2019 BMW M6, both the S65 V8 (E63 M6) and S63 twin-turbo V8 (F06/F12/F13 M6) suffer from premature rod bearing wear. The S65 is particularly notorious — the OEM rod bearings use a copper-lead composition that wears rapidly, especially with frequent cold starts and short trips. The S63 has improved bearings but can still experience wear at higher mileages. Failure to catch worn bearings leads to spun bearings and catastrophic engine failure.
Common Symptoms
- Metallic ticking or knocking from engine at idle
- Copper or bronze particles visible in oil filter
- Oil analysis showing elevated copper and lead levels
- Roughness felt through drivetrain at low RPM
- Engine knock under load
How to Fix
Perform a preventive rod bearing replacement between 60,000-80,000 miles on S65 engines, and inspect by 80,000-100,000 miles on S63 engines. Use upgraded ACL or King XP bearings with coated surfaces. Cut and send used oil filter for analysis — bearing material particles indicate wear progression. The job requires engine-out on the S65 (approximately 20 hours labor) or can be done in-car on the S63 with the oil pan dropped.

On the 2013-2018 BMW M6 S63, the S63 4.4L twin-turbo V8 engine in the F06/F12/F13 M6 (2013-2018) has rod bearing concerns similar to but less catastrophic than the S85 V10. While the S63 bearing clearances are better than the notoriously tight S85, bearings can still wear prematurely under hard driving or track use, especially at high mileage. Bearing wear is accelerated by BMW's recommended 10,000-mile oil change intervals (too long for this engine). Preventive rod bearing replacement is recommended at 60,000-80,000 miles for peace of mind, particularly for cars that see track days or spirited driving. Oil changes every 5,000-7,500 miles are mandatory to extend bearing life. ACL Race Rod Bearings 8B1578HX-STD ($150-250) or King Bearings SV Series are the community-recommended upgrades over OEM. WPC-treated bearings from Lang Racing offer the best durability for track use.
Common Symptoms
- Faint ticking or knocking noise from bottom end (early wear)
- Elevated copper/lead levels in oil analysis
- Oil pressure drop at idle when engine is hot
- Metal particles on magnetic drain plug
- Engine knocking under load (advanced wear)
- Catastrophic engine failure (if bearings spin)
How to Fix
Preventive rod bearing replacement at 60,000-80,000 miles using ACL Race Rod Bearings 8B1578HX-STD ($150-250), King Bearings SV Series, or WPC-treated bearings from Lang Racing. Cost: $4,000-7,000 for preventive replacement. Oil changes every 5,000-7,500 miles mandatory (ignore BMW's 10,000-mile recommendation). Use Blackstone Labs oil analysis ($30/test) every 5,000 miles to monitor bearing wear metals. Preventive replacement recommended for peace of mind, especially on cars used for track days or spirited driving.
