Horrible quality, no more Audi for me

If you are on the market for an Audi, pay attention, these issues are common for many models.... When I bought my 2015 A8L year and a half ago, I was so happy with the purchase. I always loved Audi brand and owned a 2005 A6 many years ago, without much problems, just regular maintenance. My new A8 had just over 40k miles, and with every factory recommended maintenance record, I didn’t anticipate any problems from it either. Boy, was I wrong... After later than a year I was doing 55k maintenance and my mechanic pointed out that the water pump is going to go very soon. He also said that it’s normal for these cars to have the water pump replaced at around 60-80k miles. I did not believe him, of course, I mean, come on, how can a water pump go at such miles on a $100k Audi, right??? Even on cheap old Chevies these things last for many years and at least twice as many miles... Unfortunately, my car wasn’t a cheap Chevy. In approximately 6-8 month a Check Coolant message went on, and I found that the car is leaking antifreeze. I went to another mechanic who showed me that it’s leaking from a thin pipe that connects the coolant reservoir with the engine. I replaced it, but in a week I figured that the car is still dripping antifreeze. They looked again, and it was leaking from underneath the thermostat housing. This time it was much more painful because the supercharger had to come off which took some labor $$$. Well, after all said and done, they pressure-test the system to make sure there is no air, and guess what.... the water pump leaks!!! If I didn’t see all three leaks with my own eye, I wouldn’t believe it - my beautiful and well-maintained Audi A8 is nothing less than a leaky bucket - it was leaking antifreeze from three separate locations, TREE, Karl!!!! So much for the famous German quality.... I hope this issue is resolved, and here is another one that I’ll have to resolve soon. I started noticing a slight steering wheel vibration when I touch break pedal on the highway. Obviously, the front rotors are going bad, and I’ll need to replace them when the breaks are due. Around $300 per rotor for this particular model. One again, we are talking about a flagship Audi sedan with just over 60k miles of it. Its currently wearing its second set of breaks ever, and the rotors are starting to get bent? Isn’t this too early for this type of car, Audi? Anyways, I wanted to love this car, and I thought it was a great alternative to the 7-series or S-Class. Unfortunately, it’s not. I’ll probably stick to it for now, purely because I just spent so much money, but when I get rid of it in a year, I’ll never buy another Audi again. Ever!

For the price, it is the best premium executive sedan you can buy. It is comfortable, quiet, handles great, come standard with AWD, the standard BOSE surround sound system is good, and it gets great gas mileage.The S class Mercedes is also a great car, but costs more, does not use the Quatro system in their AWD, does not have an all aluminum chassis (no rust), does not handle as well, and does not get as good gas mileage. I have put 50000 trouble free miles on this car. Replaced tires and brakes.

Best in Class

2015 Audi A8 4.0T quattro 4dr Sedan AWD (4.0L 8cyl Turbo 8A)

Audi's flagship sets a high mark in the luxury sedan category. I enjoy that it is less common than the other marks, but outperforms them in many aspects. Even after three years, the model remains a head-turner and a true joy to drive on my daily 20-mile commute. Performance of the A8 4.0L T is robust, yet the look is understated. My only concerns relate to the inability of local dealerships to keep up with the service capacity demands as more Audis are sold. Also, the unexpected service charge of more than $650 to align the adaptive cruise control should be covered in the pre-purchased Audi Care package. On the whole, I am quite satisfied with what is my fifth A8.
