2018 Audi A6 problems
The Audi A6 is an executive car made by the German company Audi since 1994. Now in its fifth generation, the successor to the Audi 100 is manufactured in Neckarsulm, Germany, and is available in saloon and estate configurations, the latter marketed by Audi as the Avant. Audi's internal numbering treats the A6 as a continuation of the Audi 100 lineage, with the initial A6 designated as a member of the C4-series, followed by the C5, C6, C7, and the C8. The related Audi A7 is essentially a Sportback (liftback) version of the C7-series and C8-series A6 but is marketed under its own separate identity and model designation.
All generations of the A6 have offered either front-wheel-drive or Torsen-based four-wheel-drive, marketed by Audi as their quattro system. The A6 has also been used as the basis for the company's Allroad models since 1999.
Both petrol and diesel versions of the A6 are offered. The wide range of engines available have power outputs ranging from 150 to 333 PS (110 to 245 kW). These are inline four-cylinder turbocharged engines and more powerful 3-litre units in a V6 configuration with a mechanical compressor.

Congratulations on your new-to-you Audi A6! It's great to hear that you're enjoying your purchase and that the car was in perfect condition when you bought it. Overall, you seem to be very happy with your new luxury sports sedan. I understand that you have a couple of minor complaints, such as the interior compartment and storage space being a bit small and the inconvenience of having to connect your phone via USB cable when using Android Auto. However, these are only minor issues and do not detract from the overall enjoyment of the car. Thank you for sharing your positive experience and recommendation with others!

The rear view camera (360) could use some improvement as the low pixels make it difficult to see in low light. It's disappointing that such an important safety feature was not given more attention in a luxury auto.

I took a look at the 2016 BMW 5 series and the latest Mercedes E class (4 cylinder model). I decided against the new 5 series due to concerns about reliability in the first year of production, and the 6 cylinder E class was just too expensive. However, I absolutely loved the ride and handling of the A6. It strikes the perfect balance between sport and luxury, and it's the only German midsize car that offers REAR side airbags, as well as outstanding crash testing. The ride and handling are truly exceptional. While some formal car magazine reviews have stated that the steering is numb or light, I personally did not have that impression. The V6 engine provides ample power whenever you need it. I opted for a factory order Premium Plus with 19

Expensive car but really fabulous to drive in. Looks classy with an understated prestige that grabs attention. In a recent trip to Vermont, it handled superbly up 4500 feet mountains during a snow blitz with 3-5 inches of the fluffy stuff on the ground with temps around 22F. It was the only car that was climbing up the mountains at night!!

This Audi has proven to be a reliable car, with everything still working and maintaining its original performance and comfort even after 40,000 miles. Although there have been some issues with oil consumption, it is still within specifications and the engine is an excellent performer. The quality of materials used is evident, as the car still looks fresh and shows very little wear. Overall, this Audi is a solid and dependable vehicle that is worth keeping for a long time.The car had some issues upon delivery, such as warped brake rotors, vacuum leak, and paint and rust problems on the roof's welded seam. The radio also had a problem of turning on by itself, which the dealer could not fix. Although the seats were adjustable, they were not very comfortable on long drives. However, the engine performance was excellent, and the car has been reliable. The brake feel was mushy and uncertain, but the ride and safety features have improved compared to the previous model. The OE tires (Goodyears) started making noise at about 20k miles and needed to be replaced at 36k. The car has an over-abundance of electronic features, which can be annoying.

Are you having problems with your 2018 Audi A6?
Braden Thompson 2024-10-09
I wish I had known beforehand that the radio in this car turns on automatically every time you get in. Even if it was off when you last drove the car, it will come back on about twenty seconds later once the MMI is fully operational. You have to turn it off twice, which is unbelievably annoying. Both the dealer and corporate Audi have stated that this is how the car is designed to function. I am writing this review to warn others so they can make an informed decision. Unfortunately, this radio situation has completely soured my appreciation for the car. Additionally, it has had buzzes and rattles since nearly new, brakes that squeal loudly even after repeated trips to the service department, and the steering feel and feedback is very artificial. The voice activation is all but useless, and the automatic cruise control cuts out frequently for no apparent reason, such as bad weather conditions. Overall, I am very dissatisfied with this car.

I also took a look at the 2019 Audi A6. I used to love the 2013 A6 before I switched to the 2016 Q5. However, I was disappointed to find out that the newest A6 doesn't have Apple play. The new A6 is similar to the one from 3 years ago, except that now you can only get a 3.0 gas burning racing engine with all-wheel drive. As a young retiree, I don't need 0 to 60 in 5 seconds or to waste fuel, even if it's inexpensive. My 2013 A6 FWD had all the zip I needed and got 32 mpg on the road. Unfortunately, the 2016 Q5 AWD lost 4 to 6 mpg. The 2019 A6 only offers a 3.0 engine with poor mpg, but racing performance. I wonder who the German market is for? In the end, I happily found the Lincoln MKZ Hybrid with unbelievable bells and whistles. I get 38 mpg on a 2.0-liter gas plus electric engines. I have Apple CarPlay and multiple safety, comfort features, all at $10,000 less MSRP than an Audi A6!
