Audi’s reliability in industry rankings and consumer reports

When assessing a car’s reliability, there are few better sources than industry rankings and consumer reports.

So, how does Audi stack up in these assessments?

Let’s take a closer look!

Industry reliability rankings

First, let’s check Audi’s industry rankings.

Below is an overview of Audi’s reliability rankings from well-known industry ranking reports. We’ve also compared Audi’s scores with those of BMW and Mercedes:

RankingAudi reliability scoreBMW reliability scoreMercedes reliability score
J.D. Power232 (problems per 100 vehicles)187 (problems per 100 vehicles)195 (problems per 100 vehicles)
Sources: J.D. Power, RepairPal, iSeeCars, WarrantyWise

Tip: Are you interested in the reliability of Mercedes and BMW too? If so, we did a deep dive into the reliability of the Mercedes C-Class in this article and the overall reliability of BMW here!

Let’s take a closer look at this data:

J.D. Power recorded 232 problems per 100 Audi vehicles, significantly more than 187 and 195 problems per 100 vehicles for BMW and Mercedes, respectively. In fact, Audi was ranked in 26th place out of the 33 car brands in the reliability ranking.

Audi reliability compared to other car brands: are Audi reliable?

RepairPal has a similar ranking, with an Audi reliability score of 3/5. This reliability puts Audi at 28th out of the 32 car brands in the study.

Next up, we have iSeeCars, which gives Audi a 7.8/10 score for reliability. For reference, Honda, a brand generally seen as very reliable, gets a score of 8.1/10.

Lastly, WarrantyWise’s reliability ranking gives Audi a 74/100. This ranks Audi 28th out of 36 for all car brands.

So, what conclusion can we make from this data?

According to industry rankings, Audis are not very reliable. Audi is not the least reliable car brand, but also definitely not the most reliable. Regarding reliability, Audi generally ranks in the lower quartile compared to other popular car brands.

Keep in mind that these rankings are compiled based on research of analytics companies.

So, what if we look at reports based on direct feedback from Audi owners?

Let’s check them out!

Consumer reports

In this section, we will assess Audi’s reliability based on trusted publications that conduct surveys of Audi owners.

Here is an overview of what Audi owners have reported about their Audi’s reliability:

ReportAudi reliability scoreBMW reliability scoreMercedes reliability score
Consumer Reports60/10065/10026/100
CarComplaints.com1,011 complaints987 complaints1,140 complaints
Sources: Consumer Reports,

Of these two reports, the one from Consumer Reports contains the most input data and can therefore be considered the most accurate.

Here is an infographic of the results:

Audi reliability compared to the most and least reliable cars

We see that Audi scores 60 out of 100 for reliability. This is actually a great score, as Audi ranks 6th out of the 24 car brands here!

Fun fact: WarrantyWise also did a 750-people survey on the most reliable manufacturers, and Audi, BMW, and Mercedes were all placed in the top ten most reliable car brands.

From the results of consumer surveys, we can conclude that the perceived reliability of Audis is better than average. Consumer reports show that Audi owners don’t experience the reliability to be as bad as some industry rankings say.

What are common reliability issues for Audis?

When it comes to cars, reliability is critical.

After all, nobody wants to drive a car that will break down after driving it off the lot.

So, how has the reliability of Audi models fared over the years?

It turns out Audi has had its share of ups and downs regarding reliability.

In the past, the German automaker has struggled with several issues, including electrical problems and issues with the engine.

Here are the most common reliability issues for Audis:

  • Oil leaks
  • Failing spark plugs
  • Electrical problems
  • Oil sludge problems
  • Failing timing chains
  • Carbon build up

But, as they say, every cloud has a silver lining.

Audi has used these past challenges to their advantage, so you generally won’t experience these issues on the newest models.

However, if you’re thinking of getting a used Audi, these are still essential to know, so let’s take a closer look at them:

Oil leaks

First up, let’s talk about the dreaded oil leaks.

Many Audi owners have reported issues with oil leaks, particularly in older models.

Common oil leak points Audi

This can be a frustrating and potentially expensive issue, as oil leaks are simple to see, but very hard to find out the exact location where it’s leaking.

So, it’s essential to watch for any signs of a leak and address the issue promptly if you notice one!

Failing spark plugs

Another common issue with Audis is failing spark plugs.

These small but critical components ignite the fuel in your engine’s cylinders, which powers your car.

Over time, spark plugs can become worn or fouled, leading to misfires, reduced fuel efficiency, and even engine damage.

However, they seem to fail faster than usual on some Audis.

Here is an Audi owner that even found a spark plug that had its porcelain part broken:

So, if you’re experiencing rough idling or poor acceleration, it might be time to check your spark plugs and swap them out for new ones.

Electrical problems

Owners of older Audis are likely to be familiar with electrical problems.

From faulty sensors to malfunctioning dashboard displays, Audis have been known to have failing electrical systems:

Note: If the fan in your Audi stays on while the engine is off, it may seem like a problem. However, it is generally nothing to worry about.

Oil sludge problems

A typical Audi problem is oil sludge buildup in a turbocharged engine.

Just Google something like ‘Audi oil sludge problem,’ and you will find hundreds of results!

Over time, moisture, heat, and other factors can cause oil to break down and form sludge, clogging the engine’s oil passages and leading to reduced performance or even engine failure.

Here’s how it looks on an Audi TT that hasn’t had its oil changed for 84k miles:

So, how do you prevent it?

The answer is simple: perform oil changes every 10 to 15k miles and use approved high-quality engine oil!

Failing timing chains

Failed timing chains are another common issue that can plague Audis.

The timing chain is a crucial component of your car’s engine, ensuring that the valves and pistons are synchronized.

Audi’s EA888 2.0-liter engine was notorious for failed timing chains. The issue was caused by tensioner problems, and it resulted in complete engine failures in multiple instances.

But don’t blame Audi too much for this issue. Other German manufacturers were struggling with designing reliable timing chains too. For example, there were a few BMW 1 Series with timing chain issues too!

Carbon build up

Finally, let’s talk about carbon build up.

This is a common issue on many Audi models, particularly those with direct injection engines.

Sometimes, Audi uses Volkswagen engines (or even Lamborghini engines) since the Volkswagen Group owns Audi.

Over time, carbon deposits can accumulate on the intake valves, leading to poor performance, reduced fuel economy, and even engine damage.

As an example, here is an Audi 2.0-liter engine with only 28k miles:

This problem is caused by a combination of factors, including the engine’s design and the fuel used.

To prevent the problem, it’s important to perform regular maintenance and get premium gas for your Audi.

Your Audi might suffer from carbon build-up if you notice sluggish performance or decreased fuel economy. In that case, it’s recommended to get the intake valves cleaned.

3 Factors affecting the reliability of an Audi

Even though Audi doesn’t get the best reputation in terms of reliability, we’re convinced that if you treat it well, it will treat you well in return.

Here are some of the factors that will help to maintain your Audi’s reliability:

1. Maintenance

First up is maintenance. Who would’ve guessed?

As with any car, how you care for your Audi can greatly impact its overall reliability.

Regular oil changes, tire rotations, and other routine maintenance tasks are essential to keep your car running smoothly.

You should check if it’s worth getting the Audi Care package to ensure your Audi gets the best possible maintenance.

Also, if you notice any strange noises, unusual vibrations, or warning lights on your dashboard, it’s important to get your car checked out by a professional as soon as possible.

Catching potential issues early can help prevent more serious and expensive problems.

And when performing repairs, make sure to use high-quality parts.

Lower-quality parts may save you money in the short term, but it could cost you more in the long run if they cause further damage to your vehicle.

In addition to regular maintenance and paying attention to warning signs, it’s also important to take care of your Audi’s exterior and interior.

Keeping your car clean and well-maintained can help prevent rust and other issues affecting your car’s reliability.

A great brand to look at if you would like to get some car care products for your Audi is Chemical Guys:

Chemical Guys homepage

Their website offers a variety of high-quality, proven car cleaning products for both your exterior and interior.

Neglect any of these tasks, and you could set yourself up for a host of issues down the road!

2. Age

Another factor that can affect Audi’s reliability is age.

Like any other machine, cars inevitably break down over time.

While Audi’s are built to last, older models may experience more frequent issues related to worn parts, brittle plastics, or even rust.

3. Usage

Usage is another critical factor to consider.

If you’re someone who puts a lot of miles on their car, you may find that your Audi starts to experience more issues over time.

Also, driving in extreme weather conditions or rough terrain can take a toll on your car, potentially causing damage that could impact its reliability.

Of course, if you’re someone who only drives their car occasionally, you may get away with less maintenance and upkeep.
