What is PainRank™?

PainRank™ is a scoring system by CarComplaints.com that uses relative complaint analysis to determine which vehicles suffer the most defects. It's more than just complaint volume as the score also considers the average cost of repairs, the mileage at failure, the age of the vehicle, among other factors.

Bottom line: the higher the score, the more painful it is to own.

Tell Us What's Wrong With Your Buick

The best way to find out what's wrong with a vehicle is from the people who drive them. Not only do owner complaints help us rank vehicles by reliability, but they're often used to spark class-action lawsuits and warranty extensions. Plus, they're a great way to vent.
