Engine And Engine Cooling Problems of Audi A5 - part 1

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.

After fueling, mpg was 370 and dropped to 325 within one minute. Same night, vehicle began to jerk back and forth and cluster stated "drive system: malfunction! please contact service. " took to dealership next morning and service stated fuel pump codes popped up. The vehicle is just leased and only has 1,000 miles.

Water pump leaking.

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.

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.

While I was driving, my car started to slow down and eventually stopped in the middle of the road. There were no warning sensors or indicators on the car. Ii then started to see smoke coming from my hood and decided to turn off the car and get out to inspect. On the right front side, I saw a fire under the car. The fire department was called and they put out the fire. They suspected an electrical issue, however it has yet to be confirmed. I contacted the dealership and they said they do not handle repairs of that sort. Insurance sent out an estimator for the damage. The car will be sent to a mechanic to diagnose the issue.

2014 Audi A5. Consumer writes in regards to after run coolant pump safety recall. The consumer stated the recall repair exceeded a reasonable amount of time.

Safety recall 19n4 (NHTSA 18v229) was issued in June 2018. Attached notice indicates that vehicle should be parked outdoors as a precaution, to avoid a fire caused by a short circuit within the electric coolant pump. Recall repairs are not anticipated until late 2018. I do not want to wait 4 months to get a repair since this is an obvious safety issue. I talked to my local service person at Audi danvers, MA who confirmed the recall repair is not yet available. I also emailed Audi USA but have not received a response. What can I do to get this rectified?.

Audi safety recall 19n4 continues to not be available. Received first notice for recall in June 2018. States there is a safety issue with after run coolant pump. States that this defect may cause a fire even if car is not turned on and recommends to park the vehicle outside as a precaution. This sounds very dangerous. Today, September 4, 2018, the dealer informed me that the fix for the defect is still not available and there is no date. I am concerned about driving this car and parking it in or near the house.

I purchased this vechiled 10 months ago. At 800 miles, the engine light came on. The crankshaft, throttle body and cam adjuster were all reported to Audi USA and repaired or replaced. I was informed by the dealer they wanted to replace the engine. Audi USA is saying it was only a bracket. The car still pauses and jerks when accelerating, and has an annoyingly loud vibration. I am not confident in the Audi brand anymore, and after 10 previously owned Audi - I am moving on to their german competitor.
