2019 Audi S4 problems
The Audi S4 is the high performance variant of Audi's compact executive car A4. The original Audi S4, built from 1991 until 1994, was a performance-oriented version of Audi's 100 saloon/sedan. All subsequent S4s since 1997 have been based on the Audi A4; and as the A4 has evolved from one generation to the next, so has the S4.
Like its regular A4 counterpart, all S4 variants have had longitudinally oriented, front-mounted engines. All versions of the S4 have their transmission mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a transaxle, and like all Audi "S" cars, are only available as standard with Audi's quattro all-wheel drive (AWD) system, using a Torsen-based centre differential system. A more powerful internal combustion engine, larger upgraded brakes, firmer suspension, larger wheels, and distinctive sheetmetal, styling clues and badging have always been amongst the many upgrades the S4 receives over its mainstream 100 and A4 siblings. In markets where the even higher-performance Audi RS 4 is not offered, the S4 is the top-of-the-line trim of the A4 family.
A single turbocharged 2.2-litre inline five-cylinder powered the original C4 version, and a 2.7-litre twin turbocharged V6 engine was found in the B5 generation. The B6 and B7 versions shared a common 4.2-litre V8 engine, the first time that a V8 engine was placed in a compact executive car, placing it in direct competition with the BMW M3 (3.2 L inline 6) and Mercedes-Benz C32 AMG (3.2-litre supercharged V6). The B8 generation uses a supercharged 3.0-litre V6 TFSI engine and competed with the BMW 335i, BMW 335i/340i xDrive, and Mercedes-Benz C350. The current B9 generation is powered by a turbocharged 3.0-litre V6 TFSI engine, with rivals including the BMW M340i xDrive and Mercedes-Benz C450 AMG/Mercedes-AMG C43 4MATIC.
All versions of the S4 have been manufactured at Audi's plant in Ingolstadt, Germany; they are, or have been available as a four-door five-seat saloon and a five-door five-seat Avant (Audi's name for an estate car/station wagon) body styles since the model's inception in 1991. A two-door four-seat Cabriolet (convertible) S4 variant was introduced as part of the B6 and B7 generation A4 lineups. The B8 Cabriolet has now been built off the A5 coupe body style and the "S" variant is marketed under the Audi S5 nameplate.

I recently purchased the S4 after researching many similar vehicles, including BMW and MB. I previously owned a 2011 Infinite G37X, which I loved, but the Audi is simply the best vehicle I have ever driven. I highly recommend the Napa leather package and the S Sport package, as they make a huge difference. The car handles amazingly, and it feels like there is someone sitting behind me steering my rear wheels while taking turns or curves at a higher speed. The six piston brakes are also awesome. I cannot find anything to nitpick about the steering, suspension, brakes, transmission, or anything else on this car. This car is solid all the way around, and I look forward to getting into it every day. Lastly, for you audio enthusiasts, the Bang & Olufsen stereo is also amazing. The louder you play it, the better it gets. I hope this review helps you when you are trying to make your decision.

This car is amazing! When you put it in Sport mode, it feels like a rocket. Even as a daily commuter, it still gets decent mpg. I find the car to be incredibly comfortable, especially with the upgraded nappa leather seats that have a massaging function. The lumbar and side bolsters are also fully adjustable, making it easy to find the perfect position. The technology inside the car is top-notch, with features like virtual cockpit and available google earth and live traffic. The only downside is that the screen isn't a touchscreen, but that's a minor issue. The road noise at high speeds could be better, but with the B&O 3-D sound system, you won't even notice it. Overall, this is an excellent sports sedan that I would definitely consider getting again.

It sounds like you did a lot of research before making your decision, which is always a good idea. It's great to hear that you're happy with your choice and that the car is meeting your needs. Thanks for sharing your experience with me!

I recently passed 60,000 miles on my 2018 Audi S4 and decided to write a new review. This car is a replacement for our 2010 Audi S4 Prestige and we compared it to the Mercedes C43 AMG and BMW 340i xDrive. For those seeking a highly competent daily driver, this car is nearly perfect. It's quick enough for the street (0-60 in 4.3 seconds), has strong brakes that aren't grabby, and good handling thanks to the torque-vectoring diff that provides a bit of rotation without feeling artificial or unpredictable. The suspension is supple and allows just enough body roll to give a nice sense of loads, and the car has high limits (0.99 g). The steering is accurate, if a bit numb, and has good on-center feel. The cabin is outstanding, and I much prefer it to the latest generation of Audis and BMWs. The seats are adjustable, supportive, and comfortable for long trips. The Bang and Olufsen sound system is very good, though not exceptional. Compared to my 2010 S4, the new B9 car has far better suspension compliance and less grabby brakes. The ZF 8-speed in the B9 is not as engaging as the DCT in the B8, but it's more reliable and provides peace of mind. Overall, I highly recommend this car to anyone looking for a reliable and competent daily driver.Our car has been a reliable companion, having followed the factory maintenance schedule for over 60,000 miles without any mechanical problems. With mostly highway driving, we have achieved a lifetime average fuel consumption of 29 mpg. While it is possible to achieve consumption in the teens if you drive aggressively, we recommend driving responsibly. We have noticed that the car can be slow to respond to strong throttle inputs in any mode other than Dynamic, which can be a concern in certain traffic conditions. However, we have found that switching to Dynamic mode by giving the shift lever a second tug from D solves this issue. The backup camera image quality could be better, but the overhead view compensates for it. We have made some non-OEM changes, such as fitting Michelin Pilot Sport 4S summer tires and getting aftermarket 18

As a BMW fan, I was initially hesitant to switch to the S4, but I took a chance and I'm so glad I did! This car is truly amazing. I recently drove it from New Jersey to San Diego and it was a breeze. The Quattro handled everything from downpours to sharp turns with ease, and the 3-way massaging seats kept me comfortable throughout the journey. The S4's driving dynamics are top-notch - it accelerates like a rocket and handles like a dream at any speed. The different driving modes are a game-changer, especially when road conditions change. The tech features are also impressive - the adjustable color heads up display with Navigation and speed sign recognition worked flawlessly. The lane keeping assist took some getting used to, but it ended up being a helpful feature during long drives. The Navigation on dual screens is also a nice touch and highly customizable. The only downside was that the Audi Connect's download speeds were a bit slow when searching for weather or traffic updates, but that's a minor issue considering all the other amazing features of this car.Overall, this car is fantastic and I'm looking forward to enjoying it for many years to come.

Are you having problems with your 2019 Audi S4?
Westley Welch 2024-09-23
If you're considering buying a sport model from Audi and you're a bit of an Audi enthusiast, it's important to do your research. I personally own a brand new S4 2018 model, and after just one year, in 2019, all four tires had completely worn out and split. As a lady driver who drives carefully, this was a real shock and made me feel quite nervous about driving. What's more, I was never told upfront that S Sport models require a special alignment that costs double due to a camera sensor, which can also cause tires to have a shorter lifespan. When I brought my S4 in for a second recall service, I was told that my tires were split and worn, and that this was common for most S models. They even suggested that I consider getting a regular A model instead. It's frustrating to hear these things, and I've recently heard a lot of bad news about Audi and disappointments from their clients. One person said their engine light came on just three days after buying their car, while another said they started hearing strange noises after just a week. And after the 50,000 mile warranty, the cost of parts and services can be substantial. So, it's worth considering alternatives like BMW, Mercedes, or Porsche. Do your research and make an informed decision.

I really enjoy how Audis perform on the track, but I have noticed that the S4 can be a bit too heavy, which can lead to some wear and tear on the tires and brakes. Additionally, I have had some trouble finding good service at Audi dealers in the DC/MD area without feeling like I'm being taken advantage of.
Bernardo Ullrich 2024-03-07
I strongly advise against purchasing the 2019 Audi S4 prestige due to my personal experience with major issues such as a broken sunroof and fuel injector problems at 2k and 4k miles respectively, and now at 6k miles, the fuel injector is acting up again with significant lag and poor gearing.
