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.

After purchasing the vehicle on 8/2/25, I discovered it had outstanding safety recalls that were neither addressed nor disclosed by the dealership at the time of sale. I have since taken steps to fix these safety issues, but the dealer’s failure to inform me or resolve the recalls before the sale put me at unnecessary risk. I urge the NHTSA to review the dealership’s records from 8/2/25 to hold them accountable for selling a vehicle with unresolved safety defects that compromised my safety. It is not allowing me to add case card with report, only case card available as of today.

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

My complaint is that Audi USA refuses to cover my damages and repair cost for the failed AC Evaporator that is covered under their warranty extension # AWA-21-01. Audi has a known issue for A/C Evaporator. The vehicle AC issue was immediately diagnosed by an independent mechanic who only diagnosed the issue and recharged the system until the Audi dealership had availability to inspect and perform the repair. Jim Ellis Audi was told of the issue and how using a sniffer tool the leak was found inside the cabin. Jim Ellis Audi said they would have to run their own diagnostic and if they found the leak that Audi would cover it. They did not find the leak and did not use the sniffer tool and claimed they detected the wrong refrigerant and would recharge it with the correct refrigerant. I had no recourse at this point only knowing my issue was not fixed. I was told that if it happen again to bring it back and they will credit the repair and perform further diagnostics. I felt ignored and opted for a different Audi dealership (Audi Marietta) Almost 6 week later the refrigerant has leaked again and I took the car to Audi Mariette with the same AC issue. The Audi Mariette dealership confirmed the Evaporator failure and performed the repair. I contacted Audi USA requesting a refund for the cost for Eurofed chargers ($298.26) and Jim Ellis Audi charges ($419.84)and was denied claiming the the failure was a result of the wrong refrigerant. I challenge Jim Eillis Audi at the time for the failure to properly diagnose the issue and only performing a band-aid repair of recharging and allowing refrigerant gas to leak into he cabin for a second time. When I asked what was the wrong refrigerant they detected, they could not tell me. I think Jim Ellis dealership is trying to cover their mistake and poor workmanship. Audi USA refuses to escalate my complaint. The fact remains that the evaporator initially failed all cost should be cover by Audi.

Piston 3 imploded causing damage to the long block. Complete engine failure at 65K miles conformed by Audi dealership. You may view the car if you wish. The warning lights appeared the same day the car started malfunctioning. No advanced warning. There are several class action suits in the U.S. with the same issue of complete engine failure on low miles for several Audi models from 2012 - 2017. These cars are meant to run for 150k-200k miles, not completely fail at 65k miles. Cost to repair is $10k - $17k. I would like this to be reviewed for recall. My car is a 2014 Audi A5 2.0 Turbo VIN# WAURFAFR0EA054821

I have experienced several failures and 3 recalls with my vehicle since I purchased it brand new. I have paid out thousands of dollars over the years for repairs that I feel were faulty being that I am on the only owner of the vehicle. I have approximately a little under 75k miles on my vehicle although I purchased in 2012 (2013 vehicle) only to take it to dealerships and pay for this and that but most recently my major complaint is my car has stopped on me 4 times and I paid originally for what the dealership stated was the problem only to take it back 3 times and now they state the FUEL PUMP is the problem and there is no recalls. Audi is known to have recalls on FUEL PUMPs but at this time do not reflect on my vehicle. However, my car has not been in an accident, I am the only owner, the mileage is under 100k and there is no explanation as to why the fuel pump needs replacing. Please look into this. Thank you.

NHTSA complaint #11498640 — an unverified report by a vehicle owner.
Audi claims to have fixed their 2.0t engine piston defect which can cause safety issues and accidents caused by the car seizing or loosing power at any time due to their faulty pistons which class action act filed on 2014 indicates that 2012-2017 2.0t engine are susceptible to the same default. The company tried to hide this and failed to fix the issues on vehicles pass 2011. Please I have kids and this is our main vehicle I am being told by the dealer that I need a new piston rings based on the same issues they have encountered but is not eligible for that recall. There are law suit filed against this this a safety hazard for anyone in the road and Audi offers no assistance other than requiring more money for tests that ultimately will lead to what he say was needing a new piston.
