Deferred Failure Risk
Vehicle-specific risks from this model-year's complaint record, known defects, and service milestones
One failed component has created stress on connected systems. Repair costs compound quickly — a $500 fix can become $3,000+ if cascade damage is ignored.
Owners of the 2015 AUDI S8 report engine/powertrain issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.

Water Pump and thermostat has a faulty design that causes coolant to leak either around the O Ring and/or the elbow. I am in my third water pump and thermostat with only 69,000 miles on the vehicle. Issue appears to be common on the EA824 (4.0 twin turbo) engine with hundreds of reports from the complete range of EA824 equipped vehicles (S8, RS7, S6, S7, A8 etc). Average mileage of those reported are 65k miles or so. Hundreds of similar issues are reported via various Audi forums and social media groups. Poses a fire risk since coolant leaks all over the front of the engine. Poses another safety risk if the engine seizes due to overheating while in motion. Either would be catastrophic
The contact owns a 2015 Audi S8. The contact stated he was unable to start the vehicle. The contact stated that the Electronic Power Control (EPC) warning light was illuminated. The contact was able to start the vehicle, but the vehicle was shaking while driving. The contact also stated the vehicle had stalled. The contact took the vehicle to an independent mechanic and was informed that the oxygen sensor and oil pressure switch needed to be replaced. The vehicle was repaired but continued to experience the failure. The contact took the vehicle back to an independent mechanic and was referred to a local dealer. The contact called the local dealer and made them aware of the failure. The vehicle was not diagnosed or repaired. The VIN was associated with NHTSA Campaign Number: 22V178000 (Engine and Engine Cooling). The manufacturer had been informed of the failure. The failure mileage was approximately 116,000.
Turbo failure and positive crankcase ventilation (PCV) failure. Whining noise from PCV and smoke out the tail pipes with no power. Had to pay out of pocket to remedy issues.
WAS DRIVING ON A SATURDAY AFTERNOON DOWN A BUSY STREET WHEN MY CAR STARTED SPUTTERING AND HAD VERY REDUCED POWER. I WAS ABLE TO EVENTUALLY GET TO THE SIDE OF THE ROAD AND SHUT THE CAR OFF. TRIED STARTING THE CAR AFTER A RESTING PERIOD AND CAR WOULD NOT START. LET IT SIT LONGER AND FINALLY GOT IT TO START BUT CAR HAD VERY LITTLE POWER WHEN PRESSING ON THE GAS , BUT I WAS ABLE TO GET TO MY LOCAL AUDI DEALER FOR A DIAGNOSIS. ($190.00 + TAX). I INFORMED THE TECHNICIAN OF THE ISSUES I SAW AND ALSO THAT I HEARD A WHINING NOISE COMING FROM THE ENGINE. DIAGNOSIS WAS THAT BOTH TURBOS HAD SIGNIFICANT "PLAY" IN THEM AND THEY NEEDED TO BE REPLACED. THE TECH SAID THAT THIS IS CAUSED BY AN OIL SCREEN DEEP INSIDE THE ENGINE, WHICH IS A KNOWN CAUSE OF THIS ISSUE. PRICE TO REPAIR WOULD BE $11,500.00!!!! IF THIS IS A KNOWN ISSUE AS AUDI STATES, WHY ISN'T THIS A RECALL ISSUE, ESPECIALLY WITH THE COST INCURRED BY CONSUMERS?
ONLY 43,750 MILES AND THE ENGINE IS BEING COMPLETELY REBUILT. NEW CAM ADJUSTERS, NEW TIMING CHAIN TENSIONERS, NEW TIMING CHAIN GUIDES... THIS SHOULDN'T HAPPEN ON A CAR WITH SUCH FEW MILES.
I WAS DRIVING AT HIGHWAY SPEED WHEN THE ENGINE SUDDENLY STARTED TO SHUDDER AND LOSE POWER. THE CHECK ENGINE LIGHT IMMEDIATELY STARTED TO FLASH AND THE ENGINE STALLED. I WAS STOPPED IN A BUSY HIGHWAY DURING RUSH HOUR. I EVENTUALLY GOT THE CAR TO A SAFE LOCATION AND PULLED THE TURBO AIR INTAKE TO INSPECT THE TURBO WITH A BORESCOPE. THE BANK 1 TURBO HAD DAMAGED ITSELF. THIS SHOULD NOT HAPPEN ON A CAR WITH ONLY 50,000 MILES.
Component Failure Cascade Risk
Known patterns where one defect leads to more severe downstream failures
▸ Valve and piston damage — timing chain/belt failure causes immediate catastrophic engine damage at any speed
▸ Engine stalling at speed — fuel delivery failure can cause sudden loss of power in traffic or on highways
