‘Named and Shamed’ List of Cars to Avoid

It’s always nice to know if there are cars that should be on your cars to avoid list if you’re shopping for a new or used car. This list of cars brought to us by Car Wow is a great compilation of the most unreliable cars of the last decade. For the past 10 years, these models have given owners the most problems and had the highest cost to repair.

In the video below, you’ll see 15 car and SUV models. They make up the least reliable vehicles for the past 10 years. So we’ve taken all of the cars of that list to give you this condensed list. These are the most unreliable cars of the last decade, ‘named and shamed.’

Collecting the data

In order to get this data on the most unreliable cars of the last decade, Car Wow got in tough with Warrant Wise. They took the probability of something going wrong with a particular model and multiplied it by the average cost per claim to come up with this list of cars to avoid. In addition, the highest claim filed within the last 10 years also adds to the data that gives a car a spot on this dreaded ‘named and shamed’ list. Each cost is listed in pounds due to the fact that Car Wow is British. So each of these prices is even higher if they’re projected in U.S. dollar amounts.
