AUDI A4 Reliability by YearBest & worst years, problems & recalls — NHTSA data

I have a 2021 audi a4 that is also being affected by the instrument cluster failure/recall. My model , a4 was not included but I am experiencing the same failure and this was reported to the dealership. An online search will show just how many people have issues with the instrument cluster. The instrument cluster screen just went out while driving. I have to monitor my functions via the app on my phone. The dealer wants to charge me full price when every other model in 2021 has been recalled for the same issue. The A4 should be added to the instrument cluster recall for 2021 audi.

The main instrument cluster is not stable- it tries to start up then crashes. As a result, speedometer, rpm’s, gas tank gauge, etc are not available while driving. The screen displays blank with a red triangle, tries to start up then crashes again. This seems similar to Audi recall campaign 90VC, but for some reason the A4 was not included in the recall, but I’m having similar symptoms with my A4.

The vehicle at 13,xxx miles on the high ways, and during stop & go traffic; vehicle begins to tremble, transmission and floor shakes, rpms are higher than normal, abnormal noises coming from engine (screeching), jerking on acceleration on the first gears, rough idle, happens only on highways after 1hr of driving. Can drive over 40 min without any check engine light turning on. No codes come up, while clearly having issues. After a day of being off, car goes back to normal without those issues, just vibrations and pulsing on idle. -happens on Texas highways where vehicle begins to have trouble with acceleration and transmission shakes yet no check engine or error messages appear. -problem has been shown to one Audi dealer while happening and another Audi dealer was able to reproduce the problem. They even noted how vehicle will do all the issues noted above while not providing any error codes or messages. - vehicle has been inspected but all they do is reset software and hand back keys. While issues are still prevalent. - no warning, no over heat or any codes appear on the vehicle. Issues started at 13,xxx miles. Only on long highway or stop and go traffic does it happens

Owner of 2019 A4 recently purchased from dealership after lease expired in Feb.2023. Currently with only 36,800 miles, took vehicle to inspect on Nov.24th and nothing but a front light replacement and suggestion of new tires in inspection video. The factory warranty due to expire the following week, Dec. 2nd 2023, and I was inquiring as to cost of extending warranty, but di not purchase, was waiting until after holidays. The following weekend, Tank Malfunction light turns on, from nowhere and displays zero gas on the dashboard. The previous night we filled tank with superior gas from the same gas station we use, nothing odd.. Call dealership next business day, they state the factory warranty expired and cannot cover anything. I call AUDI USA and they suggest that Audi dealership service inspect and they do and after inspecting the car conclude that I need a new fuel tank! A brand new car needs a gas tank! Service advisor states I have a faulty tank and it is because of ibad gas? What is bad gas? I mean really? I put the same gas as always, superior. I received no warning lights. The dealership's inspection from the previous week did not detect anything either. It is a safety concern to drive not knowing how much gas one has. I suspect the gas gauge has an issue. The sensor is in the fuel tank hence the suggestion to replace the whole tank at a cost of $3880! The dealership should assume responsibility for not detecting during inspection. Even though factory warranty expired within a week of incident, they should provide a grace period. AUDI USA must investigate. I AM REGRETTING MY AUDI PURCHASE!!! This sensor is faulty and is dangerous and I am not the only owner who has this problem occur. It is unacceptable that this car not perform as expected and gas tanks usually have a 20 year life span! I believe that 46,000 cars were recalled with gas gauge issues and although this car is not in that recall does not mean it can be defective.

Vehicle was inspected at 50,000 miles by the dealer and report says that passenger side motor mount was leaking. They also said that the motor mount will deteriorate rapidly and will affect the safety of the vehicle.

Audi Presense kicked in so violently on the 280E freeway towards NYC from Northern NJ, that my 15 y/o son now has a significant cervical spine injury, necessitating medical evaluation and treatment. The brakes were so abruptly applied by Presense that we thought we had been hit by a car, but had not been in an accident. This is very dangerous, and now my son is injured, despite no accident occurring.

The front passenger airbag light goes on and off randomly whenever if there is someone sits at the front passenger seat. The problem is exactly same as described in Recall 21V874000. Audi A4 2019 is on the list of recall, but my car wasn't been recalled for no reason.

I am filing a complaint concerning my recent experience with the Audi service department located in San Rafael, California. On May 24, 2021 I brought my 2019 Audi A4 in for service due to an error message stating, "Front parking aid: malfunction! Obstacles cannot be detected". I purchased the car in December 2019 from the dealership in Burlingame, California. It was previously used as a loaner car, and to my knowledge the car was in original condition with no prior bodywork done on the vehicle. When my car was inspected by the dealership in San Rafael, they discovered the error message was the result of a faulty left center front parking aid where pinched wires were found from a previous bumper repair/ removal. I was told that this work required immediate attention, wasn't covered under warranty, and the total cost of repair was $784.29. I explained to the service advisor, Gene Frank, that the car had never been in a collision since I owned it, and Gene stated that this is a common problem with Audi cars and if he filed a claim with the company, it would be rejected. Gene argued that my car may have been hit in the front by another car on the street, and when I asked why the front of the car doesn't show damage, he explained it was due to the plastic coating on the outside of the surface. Based on the pictures taken by the service inspector and the reasoning for this damage, I argue that this damage was due to a faulty wire. The car is garage kept, has low mileage, has never been in a collision, and has never had body work performed on it. For all these reasons, I dispute the cause of this wire damage. I want Audi to take responsibility for this repair, recall this type of wiring, and refund me the total amount paid for repair.

Rear Suspension cross- member. Extensive corrosion hidden behind stone guard trapping dirt and moisture. I would not have known the rust was there if the stone guard had not come apart from the cross member I cannot trust the safety of this vehicle until it is repaired Audi requires a dealer inspection at the cost of the consumer. Audi Suspension cross member components are the same for many models. The Allroad should be included in the class action lawsuit.
