The Most Complained About Luxury Cars

When it comes to buying a luxury car, consumers go into it knowing they’ll be spending more money. Owner complaints are a valuable way of learning more about various models. We’ve made a comprehensive list of the most complained about luxury cars according to CarComplaints.

Whether you are buying a new or used luxury car, you want to know what you’re getting yourself into. When it comes to your care, surprises aren’t typically a good thing. Surprise! Flat tire. Surprise! Your power steering just went out in the grocery store parking lot. You get the picture.

Sometimes, it can help to see what owners have dealt with in models we are considering for purchase. That way we can hope to avoid some of those unpleasant surprises. Is one of your favorites on this list? Rest assured.

Just because these models have the most complaints doesn’t necessarily mean that they are the worst. In fact, it’s often because they are the most popular or longest-running models. That said, it can still prove extremely helpful learning about the most complained about luxury cars from the insights their owners share on platforms like CarComplaints.

The Audi A4

The Audi A4 is one of the most complained about luxury cars according to owner reports on CarComplaints. There are 219 total complaints for the Audi A4. It’s definitely one of the brand’s most popular cars.

However, it has dealt with engine problems. In fact, all three of the worst problems listed for the Audi A4 have to do with engine problems. That said, 2019 complaints really isn’t astronomical. Additionally, the most complaints are filed for older models like the 2009 and 2011 model years. U.S. News and World Report ranks the Audi A4 sedan No. 3 in its class.

The Cadillac CTS

The Cadillac CTS is next up on our list of the most complained about luxury cars. While it’s seen popularity, the Cadillac CTS didn’t survive past the 2019 model year. The outgoing CT5 and CT6 took over the market space for Cadillac’s discontinued CTS.

On CarComplaints, owners have made 277 total complaints about the Cadillac CTS. This is another used luxury car that could have engine problems. Especially problematic years seem to be anything from 2006-2009, and 2014. However, U.S. News and World Report still gives the 2019 model year the stamp of approval as a good used luxury car. That said, the publication also warns buyers about its low reliability ratings and ranked it only No. 9 in its respective class.

The Buick Regal is the most complained about luxury car

Apart from the Buick LeSabre, which hasn’t been in production since the 2005 model year, the Buick Regal is the most complained about luxury car. Owners have filed a total of 286 complaints about the Buick Regal. Without a shadow of a doubt, the 2011 model year has the most complaints, but the 2012 Regal is considered the most problematic.

This is one more the books when it comes to used luxury cars with engine problems. However, the “worst problem” for the Buick Regal is actually to do with its brakes. The 2012 model year apparently had issues with the brakes failing to engage. The problem costs upwards of $10,000 to repair.

The Buick Regal was discontinued after the 2020 model year. Still, in 2020 it had good reliability ratings and U.S. News and World Report notes its spacious cargo and smooth ride. If you love the Buick Regal, we recommend the 2015 model year or newer based on these findings.
