2018 Audi A5 problems

audi logo

The Audi A5 is a series of compact executive coupé cars produced by the German automobile manufacturer Audi since June 2007. The A5 range additionally comprises the coupe, cabriolet, and "Sportback" (a five-door liftback with a fastback roofline) version of the Audi A4 saloon and estate models.

Under Audi's internal platform numbering convention, the A5 is a member of the B-platform series of vehicles, sharing its platform designation with the A4 saloon and Avant. The first generation A5 (Type 8T) is therefore a member of the B8 family, whilst the second generation model (Type 8W6) is based on the B9. Both are derived from the Volkswagen MLB (Modular Longitudinal Matrix) architecture.

First generation (2007)

Initial release

When presented at the March 2007 Geneva Motor Show, the A5 marked Audi's return to the compact executive coupé market since the (B3/B4) Audi 80 based coupé model ended production in 1996. On May 10, 2006, Audi confirmed that the A5 would go into production. The B6/B7 A4 spawned a convertible variant but not a coupé. For the fourth-generation A4 (B8), Audi decided to spin off the cabriolet, along with a new coupé and 4-door fastback sedan, into a nameplate of its own as the A5.

The A5 was the first of the B8 family of vehicles to be released (the others being the A4 and the Q5 crossover SUV), all based on the Audi MLP platform (Modular Longitudinal Platform) which underpin the next generation A6 and A8.

The A5 is the third coupé in Audi's line up, following the second generation TT and the R8. The A5 adopted design elements of the Nuvolari quattro concept car. The A5 debuted with the 3.2 litre FSI V6 engine delivering 195 kW (265 PS; 261 hp).

Common 2018 Audi A5 problems

The 2018 Audi A5 has been reported to have several common problems by its owners. The most significant issues are related to miscellaneous problems, accessories - interior, and engine problems.

  • Excessive Oil Consumption and Turbo Failure: One of the most serious problems reported is excessive oil consumption, which can lead to the destruction of the turbocharger. This issue has affected numerous 2018 Audi A5 owners, with an average cost to fix of $20,000 and typically occurring around 24,000 miles.
  • Sun Visor Problems: Another common issue with the 2018 Audi A5 is the sun visor. Some owners have reported that the sun visor falls off, while others have experienced broken sun visors. These problems typically occur around 14,000 miles and 13,000 miles, respectively, and there is no reported average cost to fix for these issues.
  • Infotainment System Issues: The infotainment system in the 2018 Audi A5 has also been reported to have several problems. These issues include the MMI screen going blank or freezing, the system failing to power on or off, and difficulties recognizing CDs or DVDs. The 2010 A5 model has the highest reported problems in this category, but it's essential to note that these issues can affect all Audi A5 models.
  • Multitronic Gearbox Problems: Early Audi A5 models, particularly those produced between 2007 and 2016, have had more reported instances of Multitronic gearbox problems. These issues include transmission failure, power loss or immobility, shuddering, jerking, and unusual noises during acceleration or cruising. Overheating is another problem, particularly during demanding driving conditions or towing heavy loads.
  • Airbag Issues: Airbag problems can impact all Audi A5 models. The water pump is crucial in circulating coolant throughout the engine to maintain optimal temperature. When the water pump fails, circulation is disrupted, resulting in the engine overheating and the potential for severe damage to your vehicle.
  • Carbon Build-Up: Carbon build-up issues have been reported in Audi A5 vehicles. Excessive carbon build-up can result in engine misfires, leading to poor performance and decreased fuel efficiency. It’s worth noting that this problem can impact all Audi A5 models.

In summary, the 2018 Audi A5 has several common problems that owners have reported. These issues include excessive oil consumption and turbo failure, sun visor problems, infotainment system issues, Multitronic gearbox problems, airbag issues, and carbon build-up. While these problems can affect all Audi A5 models, the 2018 model seems to have a higher prevalence of certain issues, such as excessive oil consumption and turbo failure. It is essential for potential buyers to be aware of these problems and consider the potential costs of repairs when purchasing a 2018 Audi A5.

Negative 2018 Audi A5 car reviews

  1. Blaise Torp 2025-08-08

    I previously owned the 2013 version of this car, which was fantastic. However, after upgrading to the 2018 model, I found myself asking, 'why did they do that?' Let's start with the good news: the acceleration is a little quicker than the 2013 and the convertible roof operates slightly faster. The new back window is top-notch for a convertible and the new instrument cluster is very easy to configure. The speakerphone is much better and now very nice to use. On the downside, they downgraded the transmission from the super-smooth 8-speed that came with the 2013 and replaced it with a 7-speed that, while quick, is nowhere near as smooth. The GPS now primarily uses voice commands, which can be frustrating. Resorting to manual entry is cumbersome as Audi, for some reason, made this much more difficult. I would not recommend paying extra for the navigation system. They also moved the cup holders much further forward, making them nearly out of reach. And they are tucked under the dashboard slightly so that tall water bottles, for example, no longer fit. The gas tank fills very slowly and shuts off the auto-fill at most pumps. The roof rattles where it meets the driver side window, which is a bit disappointing. The driver side window sometimes stays open a little when you shut the door, but it's easy to raise it all the way with the switch. The glove box has gotten even smaller, and the settings for the heated/cooled seats are less intuitive. The door pockets are smaller too. Overall, the 2018 model has some great features, but there are also some downsides to consider. If you're looking to upgrade, it's worth weighing the pros and cons to decide if it's the right choice for you.This car has some odd restrictions. Unfortunately, the accident avoidance system has false triggers that are annoying and more frequent than expected. Be prepared for sudden braking when backing out of your driveway if there is a car crossing behind you. Additionally, the gear shifter is confusing. Why push it forward to go in reverse and pull it back to go forward? To put it in park, you have to press a small button. However, this is still a nice car. Although, after a couple of years, the car constantly displays warnings to replace the brake pads, even though it has fewer than 20k miles and the most recent service at the dealer showed that they are still like new. Overall, this is easily the most frustrating vehicle I have owned.

    It's been over 2 years and 35k miles since I got Rhi Rhi, and I'm happy to say that she's still a thrill to drive and looks as good as ever. I've taken good care of her with regular maintenance and new tires, but she hasn't had any major issues with the transmission, engine, brakes, or overheating. The paint still looks fantastic with no fading or major scratches, and the interior is holding up well too. Even my Australian Cattle dog hasn't caused any damage to the rear seats, which still look new thanks to the dog hammock I use. The ride and performance are still great, and I even upgraded to better Continental tires which improved road noise and comfort. The sporback is not only good-looking, but also practical with its spacious hatch that can fit even large items like a 65 gallon aquarium. I've noticed several newer ones in the workplace parking lot, and even my BMW-loving colleague traded in his year-old 3 series for one that looks just like mine. He raves about it often, and I have no regrets about my purchase. Despite my dealership's attempts to get me to upgrade to newer models like the S5, RS 5, or S7, I'm perfectly happy with Rhi Rhi as she is.I had a great experience with my Audi A5 Sportback! My personal mechanic, who specializes in German vehicles, told me that this car is a sweet spot that even Audi didn't realize they had created. The ride and performance are still great, and I even noticed an improvement in road noise and comfort after switching to Continental tires. The Sportback is a good-looking vehicle, and the hatch is a huge plus when it comes to loading items from places like home improvement stores. I've even loaded a 65-gallon aquarium in it! Since I've had mine, I've noticed several newer ones in my company's parking lot, and three people have asked me about mine. One of them even traded in his BMW for one that looks just like mine! As far as car purchases go, this is tied for my favorite out of the 13 I've owned. I've had no regrets or buyer's remorse. However, I did experience some issues with the engine at 61k miles, and unfortunately, the warranty had expired. Despite this, I still had a great experience with my Audi A5 Sportback and would recommend it to others.I hope you are doing well. Take care!

    This car is a blast to drive in the summer! The acceleration is phenomenal and the ride is incredibly comfortable. You might even find yourself going 100 without even realizing it! The aerodynamic styling is also very sharp and eye-catching. On the downside, the cup holders in front are in a bit of a bad location as they block some of the controls. Additionally, the glove box has lost some space from previous years and can no longer fit the owner's manual. The small storage box to the left of the steering wheel is also too small for the manual. Lastly, the pockets on the door can be a bit awkward to get items in and out of. Overall, though, this car is a joy to drive in the summer (I have yet to own it during a winter season).

Positive 2018 Audi A5 car reviews

  1. Davonte Stamm 2025-08-16

    Great car! The Virtual Cockpit makes viewing map guidance a breeze, and the Bank & Olufsen radio rocks. I found the MMI navigation to be intuitive to learn, and it only took me a day or two to get the hang of the system. I considered an A-4, but ultimately decided on the A5 hatchback because of the increased versatility and giant cargo space compared to the sedan. In my opinion, the extra cost of an A5 over an A4 is well worth it.

  2. Ben Doyle 2025-08-14

    Great design and incredible lines define this car. The Sportback has incredible cargo capacity while still maintaining the look and feel of a midsize performance sedan. Although the technology took a bit of time to get used to, after several days of driving it became second nature and things I didn’t necessarily value at the time of purchase became highly prized - like MMI, for example. I strongly recommend it.

  3. Blaze Steuber 2025-08-13

    The car has covered 24,500 miles so far. The tires wore out a bit faster than expected, and I will need to replace all four of them soon, which will cost me at least $1000. However, the car's performance is excellent for a 4cyl, especially when accelerating off the line. The interior is immaculate, and the car is very quiet on decent roads. Although it's not ideal for carrying more than two people for long distances, the storage room is exceptional for a car of this size. The Quattro system gives me a lot of confidence on the road, and I love the car's look both inside and out. The base safety systems that come with this car are also very nice to have. There are a few minor frustrations, such as the gas tank being a bit too small for city driving, and the cup holders being poorly designed. However, the Apple CarPlay issues I had early on seem to have been fixed through iOS updates, and the virtual cockpit, large on-dash screen, and user-friendly MMI system make up for any minor inconveniences. Overall, I am very happy with my purchase.

  4. Markus Fahey 2025-08-03

    The 2018 A5 Cab from Audi is a grand slam! It's super fun to drive and the exterior and interior design are minimalist and logical. The steering is crisp and the acceleration is great. The storage space is exceptional and the backseat is roomy enough for both kids and adults to enjoy the ride. The interior materials are exceptional and the nighttime lighting configuration is beautiful. If you're buying this car, I highly recommend getting the upgraded Bang and Olufsen sound system and ventilated seats. The upgraded sound is a $900 upgrade, but it's worth every penny when you're on the highway with the top down. The upgraded seats are the most comfortable I've ever experienced. Thanks to the extra stiff body and the 3 layers of soundproofing in the top, you won't lose performance due to the soft top or even feel like you're in a convertible with the top up. The only issue I've had is that the software that powers the MMI is slightly buggy. If you're considering the A5, definitely go for the Cab. You won't regret it!

  5. Warren Shields 2025-07-28

    This is my second Audi A5 Coupe and sixth Audi overall. I must say, they just keep getting better! The re-design is classy, sleek, and the engine performance, sound, and acceleration are way better. I absolutely love it and this could be the keeper! The B & O sound system is beyond awesome. While the materials aren't quite as high quality as earlier models, I still think it's a great car. The controls for the sound system aren't as user-friendly as previous models, which were more straightforward. I really dislike the new cup holder location in the front, under the dash, as it doesn't accommodate average height bottles. I hope they put them back in the center. Thank you for considering my feedback!
