Are Audis reliable cars?

Before you drive down to your local Audi dealership and sign that dotted line, it’s important to consider whether you’re buying something reliable.

So, in an earlier article, we’ve studied industry reliability rankings, consumer reports, and complaints, all to find how reliable Audis actually are!

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:

Is Audi more reliable than BMW?

Audi vs. BMW is an age-old rivalry, like the Batman vs. Superman of the automotive world.

But when it comes to reliability, the results are mixed.

RepairPal, iSeeCars, and WarrantyWise give the reliability crown to Audi, while J.D. Power, Consumer Reports, and Carcomplaints hand it to BMW.

So, which is more reliable?

4 Factors to consider when purchasing an Audi

As we’re nearing the end of the article, we would like to tell you some essential factors to consider when purchasing a reliable Audi.

1. Age

First, remember that age is not always the best indicator of a car’s reliability.

A well-maintained older model may be more reliable than a poorly maintained newer one.

This is why many car buyers seek out vehicle history reports for extra reassurance.

For example, if you’re looking to buy a used Audi, purchasing a vehicle history report from carVertical is an absolute must.

CarVertical is easy to use and provides accurate information on the vehicle’s history, such as accident history, service records, and odometer readings!

If you’re interested, enter your vehicle’s registration below:

2. Maintenance records

Next, consider the importance of maintenance records.

These documents can provide valuable information about a car’s reliability and how well it was cared for by the previous owner.

They may not be the most exciting thing to read, but they can reveal critical details about the car’s past!

3. Options and features

When it comes to options and features, more is not always better.

While choosing a Prestige trim Audi with all the latest gadgets is tempting, remember that more features can lead to more potential issues.

4. Extended warranty

Finally, think about the value of an extended warranty.

An extended warranty can provide peace of mind by covering unexpected repair costs, but it’s essential to understand the specifics of the warranty and whether it’s worth the additional expense.

You may also be able to get Audi Care, a prepaid maintenance plan designed to cover all the scheduled services to maintain your Audi’s performance, safety, and reliability!
