What Problems Does the 2015 Audi S6 Have?
Frequently reported problems for the 2015 Audi S6 can include oil consumption issues, which seem to be more prevalent in earlier production models of this engine. Some owners have reported needing to top off the oil more frequently than expected. Carbon buildup on the intake valves is another potential issue with direct-injection engines like the S6's V8, which can lead to decreased performance and fuel economy over time. Electronic glitches, particularly affecting the MMI infotainment system, have also been reported, although not universally. While the 2015 S6 generally enjoys decent reliability for a performance sedan, potential buyers should be aware of these concerns and factor them into their purchasing decision.
Recalls are searchable via the NHTSA website (nhtsa.gov) using the VIN, so check there for specifics related to any particular car. Long-term reliability hinges on preventative maintenance, including regular oil changes with high-quality synthetic oil, and addressing any warning signs promptly. Addressing carbon buildup issues when they arise is also critical to long-term performance.
