Audis are great cars, known for their sleek style and durable mechanics. When this German-manufactured car made its way to the United States, it took the industry by storm and only got better yearly. 

Like all manufacturers, some years were more robust than others, raising questions about whether it’s worth buying. Are Audis reliable, and should you consider the brand for your next vehicle purchase? We’ll answer that and more below. 

Are Audis Reliable?

When checking out the Reliability Index, the brand falls way down the list. Out of the 40 spots in one report, they fall as low as number 24, beaten by Japanese manufacturers like Toyota, Nissan, and Honda. When digging a little deeper into the issues, the lower rating was accompanied by thousands of owners that admitted the car needed numerous repairs throughout its lifespan. 

Still, some hope was shed on the brand when owners took to consumer reports to brag about their vehicle. Though there are issues here and there, many owners claimed that they enjoyed their car and were reliable for the long haul.

Common Audi Problems

Audi has a solid lineup of several different kinds of cars, all with different setups and builds. Some Audi owners took to forums to discuss common issues with their Audi. In addition, reports gathered what owners were saying and made a list of the most common problems with Audi. 

Air conditioning, braking, and transmission were among the parts and systems with the lowest rating. There were many reports of oil leaks and coolant leaks, though there didn’t seem to be a correlation or an impressive number to make it a significant issue. These are on the higher end regarding repairs, which could send you running in the other direction. But, before you do, consider the reasons why. 

First, Audi is a luxury brand competing with other top contenders. In addition, though these are the most reported issues, many were reported on vehicles with high mileage. Over time, systems that function on electrical currents wear down and have to be repaired, which is why warranties start to go out too.

To break it all down, here are some of the most common issues you’ll likely encounter as an Audi owner:

  • Electrical issues: Many frustrated Audi owners complained about their vehicle’s electrical system. Many Audi models struggle with electrical problems, from faulty tail lights to battery issues to malfunctioning power windows.
  • Oil problems: Under the hood, several Audi vehicles have been reported to have issues with oil leaks. Oil leaks may be due to degraded gaskets and unchanged oil filters. With an external leak, you should notice a puddle of oil underneath your car. If internal, you’ll likely notice the strong fumes from your vehicle.
  • Timing belt issues: Audi vehicles will eventually give way to wear and tear despite regular maintenance. Audi’s timing belts are susceptible to wear and may ultimately fail. You’ll encounter symptoms like exhaust issues, ticking noises, and strange RPMs if not addressed. This is why mechanics recommend changing the timing belt every 60,000 to 100,000 miles.
  • Faulty spark plugs: Several Audi models also received complaints regarding faulty spark plugs. According to the reports, the Audi would experience symptoms like engine misfires, rough idling, decreased performance, and poor fuel economy.
  • Oil sludge: The Audi 1.8T engine, found in many Audi cars, often runs into a problem where the engine oil turns into a thick, sticky substance known as oil sludge. This sludge can really slow down how well the engine works and, if it gets bad enough, can even cause the engine to break down completely. The problem usually starts when the engine oil isn’t changed often enough, if low-quality oil is used, or if the engine doesn’t stay cool as it should.
  • Timing chain guide troubles: Many owners have shared their unfortunate experience with the Audi 4.2 timing chain guide used by various models like the B7 S4 Avant. According to reports, the vehicles suffered catastrophic engine failure due to timing component failure, resulting in bent and broken valves, a cracked piston, and a scored cylinder. Please be advised of this issue when considering the purchase of an Audi with the 4.2 engine, especially models like the B6 and B7 S4.
  • Carbon buildup: Audi cars, particularly those with Gasoline Direct Injection (GDI) engines, often face the issue of carbon buildup. This problem, similar to plaque in arteries, gradually reduces engine performance and efficiency over time. It’s primarily due to oil and fuel vapors from the Positive Crankcase Ventilation (PCV) system, which deposit on the engine’s intake ports and valves, turning into carbon as they accumulate.

Costs of Audi Repairs

Apart from considering whether or not the Audi needs repairs, it’s good to take a look at the cost too. Though the most expensive repairs are for vehicles like the Maserati and Ferrari, the Audi comes with a much higher cost than others in its category. To put things in perspective, reports show that repair costs can go from around $150 to over $1,100. 

While many other cars of its type have average repair costs of around $300, the Audi came with average repair costs of over $500. The higher repair costs could be due to the warranty, as it doesn’t last as long as the competition. 


So you’re in the market for a used vehicle?  We’ve gone ahead and prepped some essential questions to ask when buying a used car.

Most Reliable Audis

Among the long list of Audis, a few knock the others out of the water in terms of reliability. Not only are these sharp-looking cars, but they also drive smoothly and provide drivers with years of reliability, making them a good choice for your Audi.

The Audi Quattro

This model dates back to the 80s, known for its sleek style and innovative all-wheel drive. Though it’s not one of the fastest Audi cars, it comes without worrying about issues with the transmission, thanks to the powerful and proven 2.0L 5-cylinder engine. 

Audi RS6

For an Audi that has a little pep in its step, the RS6 is it. It packs 450 horsepower and can get up to 60 mph in just over 3 seconds. Though it can get up there in terms of speed, it doesn’t have a track record for giving out and is said to last. 

Audi R8 Supercar

The R8 Supercar has a robust 6-speed manual transmission that packs 420 horsepower. Though it packs a punch under the hood and can get up there regarding speed, this model has little to no reports about the transmission or other electrical systems. 

Least Reliable Audis

Just like some models are said to be the most reliable, some are less reliable. A few models that ranked low when it came to reliability include:

  • The Audi A8
  • The Audi Q5 
  • The Audi Q7

These three are still good cars, but the reason why they score low on the list has to do with the fact that these three models have had issues with things like oil leaks, transmission issues, and oven issues with the braking system. Among reports from drivers, some of the problems with these makes started when the vehicle had more miles on them, though they were more serious the more miles were on them. 

While this doesn’t mean that buyers should avoid these makes, they should keep a close eye out for issues before they begin and keep their Audi maintained and in good shape so that it can last longer than anticipated.

So, Are Audis Reliable? 

So, after all of that, are Audis reliable? First, as we pointed out, it depends on the model. There aren’t too many car manufacturers with a perfect lineup, with some of their models known for more issues than others. When shopping for an Audi, look for reliable models and also check for the presence of extended warranties if you want to keep your Audi for a long time. 

Another option is to trade your Audi in or go for leasing options, which will often keep you cruising in new models. That’s something you want so that you can enjoy the car without all of the other issues that can come along once the miles get up there.
