Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

August of 2021. It was raining out and I drove through a puddle and my electric steering shut down. This has been a known defect for at least 10 years with Audi and NHTSA has done NOTHING about it.

NHTSA ID 11442785 · filed Dec 6, 2021

2013 Audi A4 with a 2.0 turbo engine approximately 62.5K miles and up to date with all services. I was driving on the highway at highway speeds when the engine suddenly started to misfire with a partial loss of power making the car difficult to steer. At that time the check engine light was not illuminated. I was able to get off the highway and drive home about 2 miles away from when the misfires first occurred. The police did not get involved as I was able to return home. The following week the car was towed to my mechanic where it was diagnosed that cylinder 3 had a problem. At that time the check engine light illuminated. He recommended that I tow my car to the Audi dealership as they have better availability of parts. The dealer took apart the engine and diagnosed a broken piston ring which destroyed many other parts of the engine. The engine had to be replaced with a new one from the factory. Audi should be held accountable for catastrophic engine failures that may result in injury to others due to poor engine design.

After run collant pump caught fire and damaged the engine wiring harness. I reported it to progressive insurance and they came and inspected it at a body shop. They concluded it was due to an open recall on the vehicle so insurance refuses to cover it. Had car towed to Audi dealership and they reported it to Audi USA. They came back and told me that because of the mileage and year of the vehicle that they wouldn't cover it.

Coolent migration from the coolant valve through the wire into the connection to ecu. This caused corrosion which in turn caused an unsafe driving condition by shutting the throttle pedal control to the engine off. This has been recalled on many other models and is quite prevalent in the a4 with manual transmission as mine is.

report

From owner reports, verbatim

Two of my four kids were in the rear seat. My 7 year old panicked because her seatbelt came unbuckled and she couldn’t get it back. My initial reaction was to hit the breaks and slow down. My daughter was ejected from her seat into the passenger seat head first and then landed on the floor with her booster seat on top of her. I pulled over and checked the seat belt and it would not latch. I had to drive her home unrestrained!! A few days later, different child experienced a similar situation with the middle seat. This is a concern because if the seatbelts failed during a car accident, my children’s lives were at risk. Repeated risk of the lives of children by ignoring this common issue. How many lives will it take to be protected? Minus the fear of being unable to afford repairs, or to get the vehicle in to the repair shop? As this has happened to 2/5 buckles in a matter of days, how do I know all of the buckles are not defective? Why are we repeatedly waiting for the tally marks on lives lost before we protect our children? When is it worth a single life EVEN HARMED because the life saving device has failed to keep us safe? Our family is so strict about seatbelt safety, how can this even be a gamble that anyone is willing to take? Furthermore, how do I explain to my children that this “very important” seatbelt that I check every time they kids get into a vehicle.. how am I supposed to explain that this very important piece of equipment may or may not be there when you need it and they still must wear it?I have read hundreds of forums reporting the same failures in both Audi and VW. I have contacted Audi Denver and am waiting on a quote. I am a nurse and my husband is unemployed due to the economy downturn. We are financially stretched to our absolute limits, raising children and we will not have the means to fix the failed seat belt buckles. Any safety failure like this or with airbags should be 100% under manufacturers warranty for the LIFE of the vehicle.
