While driving on the freeway at approximately 65–70 mph, the engine suddenly stopped responding to all accelerator pedal inputs. The vehicle experienced an immediate, dangerous loss of motive power in active traffic. The dashboard displayed an amber check engine light alongside the central master warning light (an amber triangle with an exclamation point inside). I was forced to coast across active lanes of highway traffic to reach the right-hand shoulder. A State Trooper was on the shoulder and approached me, but there was no formal report. After turning the vehicle completely off and waiting, the system temporarily reset, and throttle response returned. The following day, the exact same sudden loss of accelerator response occurred while driving in local traffic, again creating a severe risk of a rear-end collision. The vehicle has been taken to an authorized Audi dealership for a diagnostic evaluation. No diagnostic trouble codes (DTCs) have been provided by the dealer yet. There was no crash or injury, but the sudden, repetitive loss of propulsion on a high-speed roadway constitutes an extreme safety hazard. I am the original owner and have maintained all scheduled maintenance intervals.
NHTSA complaint #11754375 — an unverified report by a vehicle owner.
The contact owns a 2019 Audi A7. The contact stated the engine had been overheating, and the contact had to pull over to add coolant to the coolant reservoir before continuing to drive. The failure became more persistent within the last 2 months. The vehicle was taken to the dealer, and it was determined that there was coolant leaking into the engine from the water pump, vacuum lines, and the cooling system was inoperable. The part was ordered to repair the vehicle. The contact researched online and discovered that there was a Class Action Lawsuit associated with the failure. The manufacturer was not made aware of the failure. The approximate failure mileage was 50,000.

The first time, while driving at 50-55mph, the engine decelerated suddenly. After about 10-15 seconds struggles with the gas pedal and brake pedal, the car accelerated normally. I pulled safely to side of the road to shut off the engine and start again. Things seemed to work like normal. The control panels did not show any warning signs. The second and third times (couple weeks later), while driving around 40-45mph, the engine decelerated suddenly again. After some struggles like I did the first time, the engine accelerated like normal. Like the first time, the control panels did not display any warning signs. I took the car to the Audi dealer garage and they couldn't identify the problems. They performed two "engine software updates" and said hopefully it should address the engine decelerate issue. I was charged $299 for the diagnostic tests. I am worried what would happen if I was driving on a busy and highspeed Freeway!

Received an electrical malfunction - please call service warning icon on dash display. In less than one mile, I received cascading sequential warnings - including transmission and steering warnings - please pull over now. I attempted to exit the freeway on the next ramp, on the I10 Freeway in Claremont, CA on the Monte Vista Exit - but the car completely lost all power and electric (dash and all screens were dark) blocking a traffic lane. Was stranded there for over 45 Minutes until AAA/Highway Patrol were able to obtain a tow truck. Car was towed to dealer and found out it is a known issue with the 48V Alternator System in 2019 Model Year Audis. Found out alternator is unavailable due to supply chain issues and car will be out of service for at least 4 weeks! Per research on Audi Forms, this is a known issue and Audi should be recalling these vehicles and performing the KNOWN software update (TSB Software Update 27-22-45 - Version 527) on all 2019-2020 Audi vehicles with this system. I was in fear of being rear-ended and injured - and to find out this should not have happened is very disappointing. Please require Audi to recall these vehicles and update the software so others are NOT put in this same life threatening situation - and then forced to wait until the vehicle can be fixed - currently at least 4 weeks! It has happened to MANY others - just check the Audi Owner Forums on the internet. Thank you for your consideration.

I am reaching out to update complaint number 11503265. Back in October of 2022, my vehicle turned off on me one time at the gas station and would not start until I waited 5 minutes. The vehicle did the same thing about 15 minutes later after I arrived at a friends' house. Following that incident later on that night it happened again. I have also had some issues with the vehicle not accelerating.

Oil system. A quart of oil has to be added every day. Dealership says its crank case breather. Which the supercharge cause the oil to burn more. Also the antifreeze is burning more because the engine is so hot from the oil burning rapidly. Audi is aware and fails to do anything about this known issue.

Around 36k miles the vehicle had some dried coolant residue and required coolant topups every 2-3k miles. Two different dealerships performed comprehensive inspections between then and now and did not notify me of any problems. The residue was explained away in a service bulletin stating that it was normal for the water pump to weep some coolant. Now at 44k miles, I brought the car in when I saw dried coolant residue and it seemed to require coolant more frequently. Dealer notified me that the engine water pump has failed and requires replacement.

WHILE DRIVING MY 2012 AUDI A7 ON THE HIGHWAY, RECEIVED NUMEROUS ERROR MESSAGES WITHOUT WARNING ON THE DASHBOARD. THE CAR BEGAN TO LURCH, STALL, AND DRIVE ERRATICALLY WITH LIMITED DRIVING AND BRAKING CONTROL. SITUATION WAS VERY UNSAFE AND POTENTIALLY LIFE THREATENING. AUDI DEALERSHIP STATED THAT A COOLANT MIGRATION DEFECT OCCURRED. THE COOLANT PUMP VALVE FAILED INTERNALLY AND LEAKED COOLANT ONTO THE WIRING HARNESS. THE COOLANT TRAVELED ALONG THE HARNESS AND DAMAGED OR DESTROYED MULTIPLE ELECTRICAL COMPONENTS INCLUDING THE ECM, TRANSMISSION CONTROL UNIT, AND THE HARNESS / ELECTRICAL CONNECTIONS. AUDI HAS A HISTORY OF COOLANT PUMP DEFECTS AND HAS ACTIVE RECALLS FOR THIS EXACT ISSUE FOR OTHER MODELS. THIS MODEL, THE 2012 A7 SHOULD BE ADDED TO THAT LIST AS IT IS A KNOWN ISSUE AND TECHNICAL SERVICE BULLETINS WERE SENT TO THE DEALERS.

WHILE STATIONARY AND DRIVING, THE CHECK ENGINE LIGHT APPEARS ALONG WITH THE TRANSMISSION AND EPC LIGHT WHICH STATES, "TRANSMISSION MALFUNCTION. CAN CONTINUE TO DRIVE". DRIVES SLUGGISH AND "SPUTTERS" ABOVE 4000 RPM. MY WIFE (PREGNANT AT THE TIME) WAS DRIVING WHEN IT SPUTTERED AND HAD DIFFICULTY EXITING OUR SUBDIVISION ONTO THE HIGHWAY. I TOOK IT TO THE AUDI DEALER IN HARDEEVILLE, SC AND CONCERN WAS VERIFIED AS COOLANT IN ENGINE/TRANSMISSION HARNESS. (SEE UPLOADS) I'VE DONE EXTENSIVE RESEARCH TO SEE IF THIS WAS COMMON AND I FOUND A RECALL ON THE A8 FOR A SIMILAR PROBLEM. ADDITIONALLY, I WAS ABLE TO FIND SB-10053889-6593 WHICH OUTLINES THE EXACT ISSUE; SO AUDI IS AWARE OF THE PROBLEM.
