9 complaints about the 2018 Audi A5
Newest first, as filed with NHTSA by owners.
Without warning or alerts from vehicle, car became disabled while partially into a left turn at a four way intersection. Car engine would rev, but not move. Gear selector worked, but wheels would not turn. Front wheels were completely locked and vehicle had to be dragged onto a flatbed truck. Police had to be dispatched to ensure safely of other drivers passing through the intersection until my vehicle was removed. Had a [[redacted]] child in the car with me that had to be received by my spouse. After towing car to...

an ASE certified independent repair shop, a full transmission replacement was recommended. Car has approximately 38,900 miles and is 8 years old. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
2018 Audi A5 Sportback has 16,500 miles only on it. Used for city driving only; never off road. Recently went in for annual inspection and was told that my right rear coil spring had snapped in two and vehicle was unsafe to drive. Took vehicle to local Audi dealer and they confirmed broken coil spring; they wanted $3000 to repair the vehicle. I took the vehicle instead to a local mechanic who did the repair--replacement of both broken right rear spring and one on left side--for ~$1000. Mechanic noted that he has seen and repaired many Audis with similar snapped rear coil springs.
My 2018 Audi A5 Sportback previously received Audi Safety Recall 74E3 on January 27, 2023. The recall repair documentation indicates a seat POD (Passenger Occupant Detection System) update was performed. Several years later, the vehicle developed another passenger airbag fault. The vehicle displays a message indicating the front passenger airbag is OFF even when an occupant is seated in the front passenger seat. Audi diagnosed fault code B12251B, "Passive Occupant Detection System Mat Resistance Too High," and...

determined that the seat POD occupancy mat and wiring are defective and require replacement. Audi has refused to cover the repair because more than 12 months and 12,000 miles have passed since the recall repair. I am concerned that the passenger occupant detection system involved in the previous safety recall has failed again, resulting in the passenger airbag being disabled while the seat is occupied. I am requesting that NHTSA review whether the recall remedy adequately corrected this safety issue.
The MMI ( main screen) system randomly reboots every 5 minutes, even when using CarPlay, which is unsafe. Please check it out. Thank you!
I turned on my car and several malfunctions came on the dash,and would not start and went in limp mode. A local mechanic stated it's the electrical component of the coolant pump causing malfunction. He also stated that could lead the car catching fire if overheats since the 5V is dipping below due to the faulty coolant /water pump. Ultimately forcing the car in limp mode for safety precautions. The problem is I purchase my car at 87,000 miles from the Audi dealership, and the extended warranty that covers the car is 80,000 miles
I own a 2018 Audi A5. Many critical cooling system parts - including the thermostat housing, water pump housing, radiator end tanks, breather tubes, and quick-connect hoses - are made of plastic and sit in constant exposure to coolant temperatures over 200°F. Over time, these components become brittle, crack, and fail prematurely. Recently, the plastic breather/return hose between the coolant reservoir and the radiator broke apart during routine service due to brittleness. When these parts fail, coolant leaks...

quickly, which can cause sudden overheating, engine damage, and potential vehicle disablement while driving. Based on owner reports and my own experience, this appears to be a widespread issue across Audi/VW vehicles of this generation. I request that NHTSA investigate whether the use of plastic in these high-heat, high-pressure components represents a design defect that creates a safety hazard.
The water pump failed on my vehicle. Initially reported 2/2025 at Authorized Audi Service Center. They claimed it was normal for coolant to dip. Audi USA Confirmed I have a settlement class vehicle in 03/2025. Mentioned an 80K Mileage limit. (Car only had 69K miles at the time) When the issue persisted I reached out for repair in accordance to Water Pump Settlement. McKenna Audi Service center initially stated the extended warranty expired 05/2025, and mentioned an 8 Year Limit (8/80K whichever comes first) ...

9/3 Reached out to Audi USA again and they initially provided an approval. Instructed to take to authorized service center for official diagnosis. 9/5 Audi USA recanted approval 2 days later. Instructed to Call Settlement Administrator. SA stated this is fully Audi responsibly warranty does not expire until 9/2025 unable to assist. Spoke to supervisor at Audi USA who stated extended warranty did not expire until 09/26/2025 09/08 Audi Beverly Hills confirmed water pump malfunction. Sent invoice to supervisor at Audi USA. $2338.25 Supervisor informed me later that warranty is expired after all. Stated a regional manager would look at it but no guarantees. At this point I have spent $350 for a diagnosis I did not need to satisfy the demands of the Audi warranty that is now being denied.
The vehicle has 36000 miles on it and the oil cooler has failed. The car is meticulously maintained. This failure compromises the ability for the engine to cool properly. Because of the failure, coolant is then forced into the engine oil potentially destroying the engine. Engine replacements are 10,000 for these types of cars. Audi is aware of this issue and should repair all vehicles with this known issue
Engine shuts off occasionally whilst cornering at very low speed. No warning. Been happening for several years.
