POWER TRAIN
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

ENGINE AND ENGINE COOLING
The contact owns a 2014 Audi S8. The contact stated while driving 65 MPH, the low oil warning light illuminated on the instrument panel. Upon visual inspection of the engine compartment, the contact observed that the engine oil level was abnormally low, prompting him to add oil to the engine. However, afterwards the contact stated that the low oil warning light illuminated again, after which there was a burning odor inside the vehicle, and the vehicle lost significant motive power. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 58,000.

VISIBILITY/WIPER, VISIBILITY:SUN/MOON ROOF ASSEMBLY
While driving on the highway my sunroof glass detached from the frame and flipped over to the back. It was still being held by about 5in of glue on the rear part of the frame and luckily it didn't depart the car which would have caused damage to cars behind me. This issue seems the same as NHTSA Recall No. / MFR Recall No. : 16V-415 / 60C3, however my VIN is not part of it. I'm reporting this because there might be other cars out there affected by this recall, which is a road hazard to other people and vehicles that are traveling behind this car.

VISIBILITY/WIPER
During our recent rains i discovered water dripping on me from the center overhead console at the top of the windshield. This totally distracted me while driving as I was shocked by it's sudden occurrence. The next day, I suspected sunroof drains and proceeded to chase a flexible line thru them in the front drains and tested with water, it drained fine and no evidence of dripping inside. Went out driving in the rain and discovered the leaking occurring again along the top of headliner/windshield junction at the passenger pillar and again in the center overhead console. Once again distracted to catch the leaks. A Safety concern! I heard wind-noise which changed in tone as I pressed against the windshield. I'm assessing the windshield has lost its bond to the weatherstrip components. I'm shocked to find this in a $127K luxury car and it's hard to not be distracted during inclement weather.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
When started up on 11/17/22, multiple warning lights came on in rapid sequence advising of an electrical system & battery malfunction. Warning was to not drive the vehicle and contact service. I shut off the vehicle and re-started it. The same warnings were displayed. I was about 0.8 mile from the dealer so I attempted to drive it to their location. On the way, the warnings continued to show. After about 0.6 miles, the transmission fully disengaged from the engine. I coasted to the side of the street, shut off the vehicle, re-started it (same warnings showed) but the transmission was reset and worked. I drove to the dealership where my Audi mechanic knew exactly what the issue is--there is a huge problem with a Continental-supplied 48V belt starter/generator that needs to be replaced. However, none are available and won't be available until sometime in Q1 2023 or later. The replacement part is backordered with every Audi dealership experiencing this issue with multiple models in the MY's of 2018 through 2023. Had this issue occurred on an Interstate highway (complete loss of transmission), I could have been rear-ended by a vehicle following me. In a multi-lane situation, coasting to the either side of the highway may not have been possible....again, creating a very hazardous situation for me and other vehicles. I tried to attach the Audi Technical Service Bulletin showing the extent of the issue within Audi's model range and model years but it would not upload to your site. The TSB is 27 22 45 2058831/5 September 27, 2022. This is issue is leaving thousands of Audi vehicles unsafe and un-driveable. I urge you to act immediately to force Audi to recall these vehicles.

The windshield top gasket is not working and the glass can be easily pushed out an 1/8”. Wind can be heard while driving and when it’s raining water runs through steady stream. I was under the impression that the windshield is an integral part of the cars structure.

ENGINE
The car was running rough for a couple weeks; hesitant to accelerate, failed to start multiple times and idled rough. One day I was coming home from my hour long commute, I put the car in reverse in my driveway and the car started bucking so badly that it became un-drivable. At this point we had to get the car towed on a flatbed an hour away to the nearest dealership and this is when we discovered that the turbos had gone bad. There was no check engine light or any indication before it just failed. I am active duty in the United States Coast Guard and being without a car is not an option. Because of the shipping delay and waiting for the turbos to come from Germany, I was without my car for two weeks. I was loaned a vehicle but I had to rent a car for one day in between. We have been told by Audi dealerships for years that this was a known problem and to expect this $10,000 repair.

WHILE DRIVING ON THE MAIN HIGHWAY, MY CAR ENGINE SHUT OFF. I HAD DYSFUNCTIONAL BRAKE AND STEERING FAILURE. BRAKE WAS HARDLY WORKING AND I HAD TO USE ALL MY STRENGTH TO CONTROL STEERING. BASICALLY, WHILE DRIVING AT 50MPH, CAR ENGINE SHUT OFF WITHOUT WARNING AND I LOST STEERING AND BRAKING. I WAS ABLE TO PULL OFF THE ROAD INTO A VACANT PARKING LOT AND CAR CAME TO A STOP. FORTUNATELY, NO CARS WERE AROUND AT THE TIME. OTHERWISE, I ALONG WITH MY FAMILY WOULD HAVE BEEN INVOLVED IN A POTENTIALLY FATAL ACCIDENT. MY CAR HAD BEEN SERVICED BY AUDI SINCE PURCHASE. IT WAS JUST SERVICED WITHIN THE PAST MONTH. CAR WAS TOWED TO AN AUDI DEALER--THE TURBO CHARGER HAD FAILED. BASED ON THE DEALER DESCRIPTION, FAILER OF TURBO CAUSED THE CATASTROPHIC FAILURE OF BOTH THE STEERING AND THE BRAKES. THERE SHOULD BE A BACKUP SAFETY MECHANISM IN CASE OF TURBO FAILURE WITH AUDI 4L ENGINE--APPARENTLY, THIS DOES NOT SEEM TO EXIST. I CONTACTED AUDI AND THEY HAD NO EXPLANATION. IT WAS JUST BY GOD'S GRACE THAT HORRIBLE ACCIDENT DID NOT OCCUR. I HOPE YOU CAN PROVIDE SOME INSIGHT INTO THIS. BASED ON SOME BLOGS, THIS IS APPARENTLY COMMON WITH 4L TURBO ENGINES WITH AUDI.

ENGINE
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?

ENGINE, FUEL/PROPULSION SYSTEM
WHILE ON THE HIGHWAY, I NOTICED THAT THE CAR WAS NOT PICKING UP APPROPRIATE SPEED WHEN ACCELERATING. THERE WAS NO PRIOR NOTICE OR ENGINE LIGHTS OR ANY ABNORMALITIES WITH THE VEHICLE PRIOR TO THIS. I DECIDED TO PULL OFF THE HIGHWAY AT A REST AREA AND AS THE CAR WAS SLOWED DOWN AROUND 15-20 MPH, I LOST TOTAL POWER OF THE VEHICLE AND WAS UNABLE TO STEER OR USE THE BRAKES. LUCKILY THE CAR WAS ABLE TO COAST TO A STOP WITHOUT INJURY BUT WAS EXTREMELY FRIGHTENING WITH MY FAMILY IN THE VEHICLE. AFTER TOW TO THE AUDI DEALERSHIP I WAS INFORMED THAT THE PROBLEM WAS A CATASTROPHIC FAILURE OF THE TURBOS IN THE ENGINE. I DID EXTENSIVE REVIEW OF THIS PROBLEM AND FIND OUT THAT IT IS A KNOWN PROBLEM AND BOILS DOWN TO A DESIGN FLAW WHERE A SMALL OIL SCREEN ESSENTIALLY STARVES THE TURBOS OF OIL. SOMETIME THESE SCREENS HAVE CLOGGED BUT IN MANY CASES ARE JUST FINE BUT IN ALL CASES HAVE LEAD TO TURBO FAILURE. THIS IS NOT A MAINTENANCE ISSUE AND ALL VEHICLES I HAVE REVIEWED HAVE BEEN FACTORY MAINTAINED WITH SERVICE RECORDS AVAILABLE SUCH AS IN THE CASE OF MY VEHICLE. THIS IS NOT CURRENTLY COVERED BY AN AUDI EXTENDED WARRANTY AND REPAIRS ARE VERY COSTLY AVERAGING AROUND 12-13K FROM THE DEALERSHIPS. I CONTACTED AUDI OF AMERICA AND FILED A COMPLAINT (AS MANY PEOPLE HAVE) AND THEY DID NOT OFFER ANY ASSISTANCE. THEY ARE AWARE OF THIS DESIGN FLAW AND COSTLY REPAIR BUT HAVE NOT ISSUED ANY RECALLS. THIS IS CLEARLY A SAFETY CONCERN BECAUSE HAD I LOST POWER ON THE HIGHWAY I MOST CERTAINLY WOULD HAVE BEEN INVOLVED IN A CATASTROPHIC ACCIDENT. AUDI HAD RECENTLY ISSUED AN EXTENDED WARRANTY SERVICE ON A FAULTY ENGINE OIL PCV VALVE AND THAT REPAIR WAS AROUND 2-3K. CLEARLY THERE IS A TREND HERE WITH THESE ENGINES. I AM HOPEFUL THAT WITH THIS AND OTHER COMPLAINTS, THAT THIS MAJOR SAFETY ISSUE WILL LEAD TO WARRANTY EXTENSION AND/OR RECALL FOR REPAIR OF THIS PROBLEM. THANK YOU.
