Each component in detail
What the reports in each category say, in the owners' own words
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
The timing chain and tensioner in my 2014 Audi A4 Quattro (VIN: [XXX] ) failed without warning, causing the engine to suddenly stall and become inoperable while in motion. This presented a serious safety hazard. Although my vehicle is slightly outside the settlement mileage and time limit, timing chains are considered a lifetime component and are not a maintenance item, meaning they are not expected to fail and are not listed as requiring inspection or replacement under any Audi maintenance schedule. This failure was sudden, catastrophic, and safety-related. Audi and Volkswagen have already acknowledged this timing chain defect in federal class-action litigation (Opheim et al. v. Volkswagen Group of America), and my VIN is included in the affected vehicle list. Audi’s own dealership technician confirmed that the timing chain is stretched, the tensioner is fully extended, and the intake camshaft timing is off by a tooth—clearly matching the known defect. The vehicle stalled suddenly while arriving at a repair facility, and it would not restart. Had this occurred on a highway, a collision could have easily resulted. This is a known safety defect, affecting engine timing, power loss, and stall risk. The manufacturer denies responsibility despite known defects, safety implications, and VIN eligibility. I am requesting NHTSA to investigate Audi’s refusal to address a known and documented safety-related defect involving a critical non-maintenance engine component that is expected to last the life of the vehicle.

Hi My name is [XXX] and I have an 2014 Audi A4 that has been consuming to much oil ever since I bought it . I see the vehicles contained defective pistons that caused excessive oil consumption. Can you please help with this ? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
Car is feeling jerky and shaky at the steering wheel when driving or sitting still. Very common problem on these cars. Will probably need new steering rack. This issue needs to become a recall. Very frustrating.
Steering wheel doesn’t want stay center. Kicks left or right, in a kind of ‘notchy’ way. Almost feels like it wants to click from side to side and won’t stay centered. Vehicle was recently aligned and utilizes all OEM parts.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
The contact owns a 2014 Audi A4. The contact stated while at a stop sign and attempting to proceed, the vehicle stalled and failed to return to normal operation. The contact and her boyfriend shifted into neutral and pushed the vehicle to the side of the road for a while until the vehicle eventually restarted. The Electronic power control (EPC) warning light was illuminated. The vehicle was driven back to the residence where the boyfriend used a diagnostic scanner to diagnose the vehicle. The contact was informed that the fuel pump sensor needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was scanned a second time and it was determined that the fuel pump module needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The diagnostic scan tool was used again to diagnose the vehicle and it was determined that the fuel pressure regulator needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.
Driving on a two lane busy road, car started to jerk and shut down. Lost steering capability immediately, car veered toward ditch, stopped. Called 911 immediately because the road was busy and cars could not safely get around my stalled vehicle. I told 911 that I was exiting the vehicle for my safety. I could not restart the vehicle. There were no warning lamps or messages or symptoms alerting me to a problem UNTIL after the occurrence. I had no idea what was happening, and it was frightening. Never had this situation with any of my Audi's and I only have approximately 41,000 miles on it. After about 15 minutes a person stopped and was able to restart my vehicle (911) never got to me and I cautiously drove home. Called the dealer and had it serviced immediately. Diagnostics performed on it. It required a replacement of the fuel pump and fuel rail sensor. It found fuel pump control module to be shorting out. It seems that this type of issue should not be occurring on the vehicle with such low mileage.

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
This is my second time contacting you in reg. this vehicle, it was previously in the shop for the same repairs the engine was replaced and the coolant system was fixed, now it has been about two mo and again it is having issues with the coolant system and now transmission issues, I also just found out that this vehicle was in a accident in 2014, in which I was told t had not been, so I am currently reaching out to the Audi dealership trying to receive previous service history done to vehicle Oasis report. I feel this vehicle is a safety hazard, I am a single mom and grandmother and I do not feel safe in this vehicle and wish I was informed of previous accident. In the time I have had the vehicle it has spent over 30 days in the shop and now its back in there.
WHILE DRIVING THE VEHICLE, I GET AN 'ALTERNATOR FAILURE - BATTERY MIGHT NOT BE CHARGING' WARMING, FEW SECONDS LATER THE CAR ALMOST COMPLETELY SHUT DOWN, THE STEERING WHEEL BECOMES SUPER STIFF, CAN'T ACCELERATE, I ALMOST HIT A CAR NEXT TO ME WHILE TRYING TO GET OUT OF THE ROAD AND PARK IN A SAFE PLACE! LUCKILY WAS A 35 MPH ZONE, IN THE HIGHWAY WOULD HAVE BEEN REALLY DANGEROUS! I TOWED TO A SHOP AND YES, IS THE ALTERNATOR. THE CAR SHOULD GIVE AN EARLIER WARNING AND DEFINITELY NOT SHUT DOWN WHILE DRIVING!

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
The TCM doesn't properly communicate with sensors in the transmission of my Audi A4 such as one of the speed sensors and this issue is inspectable by most certified technicians. The equipment failure can result in the transmission not being able to engage the gears into a "forward" motion causing the vehicle to seemingly stall in traffic. It can also cause it to shift roughly, which could further damage equipment and pose higher safety risks to not only to me, but other drivers on the roads as well, both of which issues I mentioned have occurred to me on multiple occasions. I've recently had this issue diagnosed by an Audi technician. A "transmission malfunction" message also is present on the dashboard as a result of the aforementioned issues.

Suspension
Reports naming suspension components — springs, struts, shocks, control arms and related hardware.
From owner reports, verbatim
I BOUGHT THIS 2014 AUDI A4 USED IN 1/2019. THE CAR SEEMS TO HAVE MAJOR STEERING AND SUSPENSION ISSUES. ALTHOUGH I'VE HAD IT CHECKED BY PROFESSIONALS MULTIPLE TIMES,?ALIGNED MULTIPLE TIMES, AND TIRES REBALANCED MULTIPLE, NO ONE CAN DETERMINE THE PROBLEM. IT'S HARD TO CONTROL THE CAR ON FREEWAYS. SOMETIMES IT SEEMS IMPOSSIBLE TO KEEP THE CAR IN A STRAIGHT LINE. THE CAR WANDERS ALL OVER THE FREEWAY. IT'S VERY DANGEROUS. UNFORTUNATELY I'M UNABLE TO SUE USING THE LEMON LAW BECAUSE I BOUGHT IT USED.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The parking break malfunction light keeps coming on and off for the past few months. Last year the malfunction light came on and I was unable to release the parking break. My car had to be towed to mechanic for reviews. The light is now back; on and off for several months. I fear using my parking brakes.

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
The third brake light intermittently stops working. Being that it is intermittent, it tells me the led and circuitry are working. Also, a warning alert will illuminate on my dash instrument cluster and not when the light is working again. Upon further searching on-line, there is an issue with a solder joint cracking. I believe this is the case because when i jiggle the connector, the light will illuminate. Since this light is required by law, this is a very important safety issue. And a rather expensive one since the replacement part alone is $150-$200.

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
THE FRONT WHEEL BEARINGS WERE MAKING NOISE @ 76,756 MILES, WHILE DRIVING ON THE OPEN ROAD, SO BOTH WERE CHANGED OUT. UPON CHECKING THE INTERNET I FOUND TSB NO. 401548 REFERRING TO THE PROBLEM IN MANY AUDI MODELS FROM 2009-2016. WITH THIS EXTENSIVE PROBLEM, A RECALL SHOULD BE ENFORCED. A MONTH LATER @ 78998 MILES THE ELECTRONIC RACK AND PINION STEERING STARTED TO MAKE A RUBBING NOISE WHEN TURNED, SITTING OR TRAVELING AND AN ON BOARD RED NOTICE CAME UP INDICATING STEERING PROBLEM SEEK PROFESSIONAL HELP. THE UNIT WAS ELECTRICALLY DIAGNOSED WITH A FAILED AIR BAG CLOCKSPRING AND AN ELECTRONIC STEERING GEAR ASSEMBLY. THE CODES WERE ENTERED AND THE RACK AND CLOCKSPRING WERE REPROGRAMMED TO THE VEHICLE ONCE INSTALLED, SOLVING THE PROBLEM. THIS ALSO SEEMS TO BE AN INHERENT PROBLEM IN THIS VEHICLE, SINCE THE MECHANIC HAD KNOW OF TWO OTHER ALREADY THIS YEAR. THE CAR DID DRIVE FINE WITH THE OLD RACK AND PINION IN IT.
