On July 23, 2026, my 2023 Audi Q5 suddenly lost power while I was driving on the highway, with no prior symptoms before the incident. The vehicle began stuttering, entered limp mode, displayed multiple drive-system malfunction warnings, and developed a loud knocking sound from the engine area. The loss of power created a serious safety risk because the vehicle could no longer accelerate or operate normally in traffic. I pulled over as soon as it was safe, shut the vehicle off, and had it towed. The vehicle had approximately 74,945 miles at the time of the incident. An independent auto repair shop performed a diagnostic inspection and documented fault codes P030300 for a cylinder 3 misfire, P130A00 indicating cylinder 3 fuel injection had been disabled to protect the catalytic converter, and P013B00 involving the rear oxygen sensor. The technician reported severe connecting-rod knock from inside the engine block and found a large amount of metallic debris in the engine oil. The shop concluded that the engine had suffered catastrophic internal failure and required replacement. The symptoms and findings closely resemble the connecting-rod failure condition described in Audi recall 13i5 / the federal safety agency recall 22V753, although Audi advised that my VIN is not currently included. The vehicle is now at an authorized Audi dealership for further diagnosis. I am reporting this because the sudden loss of power and internal engine failure occurred while the vehicle was being driven and could have resulted in a crash. I request that the federal safety agency review whether my vehicle experienced the same or a substantially similar connecting-rod failure as the 2023 vehicles covered by recall 22V753, despite my VIN not currently being included.

December 17, 2024 2012 Q5 Audi Complaint- Purchased at Steve White Greenville, S.C VIN# [XXX] Dear Audi leaders, (and Michele) Thanks for replying to my request and your (brief) follow-up. I know selling cars is your main concern. I learned through years of working for tech companies such as Oracle and HP that it cost a significant more to get a new customer than to retain an old one. I expected at the very least was to lob a phone call to me, instead of pretending to- even more humiliating. The Audi Q5 was the biggest, most dangerous and worst purchase I’ve ever made. It is also the most expensive car I’ve ever maintained. I didn’t realize how many people literally got “burned” on this engine debacle that Audi created. Audi dealerships around the globe forced loyal customer who purchased this vehicle to jump through hoops to prove a very apparent engine flaw. It was like watching the Hindenburg crash, but in slow motion. Upon further research, the level of owners problems varied by engine; some were perfectly fine but most were faced with a ticking time-bomb. Audi seemed to take no blame, instead profiting on an “oil program”, expensive for the consumer and also time consuming, to solve the issue. As time has a way of flushing out the truth, a class action lawsuit quietly arose was settled in 2014. Audi shamelessly offered to cover 40% on certain cars-soon having a class action lawsuit on their hands. At that time, my Q5 had 99,000 miles on it. Because of Audi’s foot-dragging, my Q5 was too old to fix which seemed a little too well orchestrated and that is wrong. Currently, my vehicle is worth nothing and I feel 100% that it was intentionally motivated. I now have a hunk of metal that Audi refuses to fix which is not only frustrating- but is a danger to me and cars around me- It is unsafe. I was going to give it to my [XXX] daughter, but after having it looked over, it was too dangerous-at best. I was never notified by Audi when the recall was ann INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

• Excessive oil consumption • Engine knocking • Illumination of the check engine light, possibly for cylinder misfire • Engine stalling- • the pistons unexpectedly fail, drivers may also experience a sudden loss of engine power while operating their vehicles. This can pose a safety risk as it may become difficult for drivers to brake, accelerate or control the steering wheel. Drivers are believed to have experienced problems with the pistons well before they should, with some seeing engine failure before the 75,000- mile mark. Audi Vehicles Burning Too Much Oil A number of Audi drivers have posted complaints online that their Q5 vehicles are burning more oil than they should, an issue attorneys suspect could be related to a defect in the pistons. A sample of these complaints can be found below [sic throughout, emphasis ours]: My Audi Q5 2012, like all suffers from excessive mass oil consumption. A Dealer did the oil consumption test and said the piston and rings need to be replaced. I ve Already spent over $1K on crankshaft repairs etc. Will AoA to pay for new piston and rings? Its a $6K repair that I am unwilling to pay because it should not be going through this crap for such an expensive car.” This "benefit" likely won't me customers due to the age of the vehicles and they don’t seem to care. Not to mention owners will still be stuck with paying a percentage for repairs. I bought a 2012 Audi Q5 in in 2015…For the first 20,000 miles of owning this car, it was my dream car and was all I had hoped for. Then, the check engine and oil light game started. At first, adding oil meant that it would it go another 1500-2000 miles without issue. Then, around 75k, it went to 500 to 750 miles. Once it hit 95k, it dropped to every 400 to 600 miles that it needed oil. I am at 118k and desperately want to dump this lemon. Unfortunately, I have payments on this garbage car. I've spoken with a local mechanic about it and he says the fix is replacing the engine.

My 2015 Q5 is experiencing excessive oil consumption and has failed the oil consumption test. This is a known defect in older cars for which there was a successful class action suit and now it seems that this defect is also present in certain Audi cars between 2010-2017. The excessive oil consumption stems from a piston and ring defect. The defect is causing the cars' pistons and piston heads to break off into pieces. This causing a number of problems requiring costly repairs and makes the car unsafe to drive. In addition to excessive oil consumption, the car can experience a sudden loss of power while driving (which is a safety issue) and engine knocking. My mechanic has inspected the car, run the oil consumption test (which the car failed) and told me that the piston and rings need to be replaced. He also stated that he has seen this in Audi's and that it is a known problem. Currently, my low oil light is coming on every 800 miles (normal would be 5000+miles). You are welcome to inspect my car at any time.
