The turbocharger wastegate actuator failed suddenly at highway speeds, causing loss of engine power and making it extremely difficult to maintain highway speeds. The warnings that suddenly appeared caused the cruise control to cease working as well. The dealership (Audi Miami South by The Collection) inspected the vehicle and confirmed the wastegate actuator seized, requiring a complete replacement of the turbocharger. The vehicle has 53,000 miles.

The MMI component randomly stops working. Over the past four years of driving this Audi the MMI would suddenly reboot itself only once or twice a year. Now for the past three months it tries to reboot itself once or twice a day! It's quite startling for the music to go silent and the screen goes black, the first few times this happened I thought the engine died too (that's scary). It even happens when I'm backing out of my garage, luckily there is never anybody behind me but what if I'm in the mall parking lot. When the MMI reboots itself about half of the time it is similar to a conventional starting procedure, which isn't to bad but just annoying. Other times it wants you to log on as a "guest driver" or "registered driver hasn't been in the vehicle" or it even wants you to punch in a pin number on the key pad which I don't know. All this requires your concentration on the MMI and not on the road. I wish some one could inspect this and confirm my problems before I brought it to the dealer. If I brought my car to the dealer they would charge me for diagnostics and then say they "there is nothing wrong" or worse try to upsell me a whole new unit for mega dollars. I only drive about ten to fifteen miles a day so my time on the road is minimal but it only takes a moment of distraction to have an accident. While there haven't been any warning lamps or messages about the MMI problem there was another symptom to this problem. The control button on the center console and the thumb scroll wheel on the steering wheel had a very distinct delayed reaction. The volume would change 2-3 seconds after I used the knobs and even turn off 2-3 seconds after I hit the button on the console. I think this symptom started to occur before the MMI reboots. One more quirk, after the MMI reboots, the music from my USB drive will start to play not from when the MMI cut out but from when I started the car that morning. It starts to repeat the same songs. Thank You.

Engine oil consumption, timing chain. This is a massive problem among Audi vehicles across the board. Engine oil consumption is abnormal and if unnoticed leads to engine dying in the middle of the road which is dangerous and I’ve personally had this happen to me on multiple occasions. The engines timing chain goes bad and causes the entire engine to need to be replaced which consumers have to pay for out of pocket. Damage from timing chain, rough idle, sluggish engine performance, rattling, engine failure. There are large amounts of consumers experiencing the exact same issues. Something needs to be done it’s not safe at all and Audi should be held responsible and liable to fix these issues. The engines are deteriorating at an abnormal and accelerated rate.

2017 A4 B9 premium plus model, AWD, 2.0T. I have had an Audi dealership service my car for all major service intervals outside of oil change, not only at recommended intervals but even early. 3 years ago I had my 40K mile service done at 35K miles. Spark plugs were replaced by Audi Hawthorne in Westchester county, NY. One week ago, at 49K miles (well before the 6 years or 60K miles Audi says their spark plugs will last) my engine seized while driving and was misfiring. This caused an engine shut down WHILE THE CAR WAS IN MOTION on the highway. I was able to restart and make it off the highway where the car seized again. I had to then be towed 30 miles back home. Took it to my locally well known body shop that I have used for years for them to say: 1. My spark plugs were loose and installed incorrectly and 2. The electrode at the top of the plug had broken off TWO SEPERATE SPARK PLUGS and fallen into the engine, causing scoring to the engine and #4 piston as well as blow-by during combustion. They said this had to be caused by a manufacturing defect PLUS incorrect install. they fixed what they could and recommended I take it to Audi. Audi is now saying I need a whole new engine because of damage to piston 4, and not saying they will cover the replacement cost of $21,500.Â

Water Pump prematurely failed. Upon self inspection, I noticed the coolant reservoir was below the minimum requirements. I asked the dealer to inspect, and they determined the cause was a faulty water pump. At around 50,000 miles, this water pump should not have failed under normal use. I am fortunate I self inspected, as continued use may cause premature engine failure due to overheating. Overheating would cause spontaneous vehicle operation failure during normal driving conditions, stalling the vehicle on a road or highway, putting myself and others at risk for impact.

I have a 2013 Audi A4 2.0. I was driving home at night close to my home and the car started puttering and wouldn’t go and I found out that the timing chain had “jumped” and caused sudden engine failure. I later found out that same issue is the subject of class action lawsuits for the second time around because Audi didn’t properly take action after the first suit and repair the issue, which is apparently a major problem with my model and other class vehicles and instead continue to let people unknowingly buy and drive these cars.

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.
