    One of the main reasons people buy a brand-new car is the promise of a no-hassle ownership experience, free from the drip, drip, drip of service problems that set in as cars age. Nonetheless, CR’s exclusive Annual Auto Surveys tell us that some buyers will be taking their brand-new car back to the dealer’s service department sooner and more often than other car buyers will.

    The models featured here are the 10 least reliable vehicles. (For more details, check out our Guide to Car Reliability.)

    Our surveys take a deep dive into the numerous things that can go wrong with a vehicle. We study 17 trouble areas, from nuisances—such as squeaky brakes and broken interior trim—to major bummers, such as out-of-warranty transmission repairs and trouble with four-wheel-drive systems.

    More on Car Reliability

    We weigh the severity of each type of problem to create a predicted reliability score for each vehicle. To be considered for this list, we must have at least two model years of data in calculating the predicted reliability score.

    Based on that analysis, these models are the least reliable. They’re presented in rank order, counting down to the least reliable model. Each is shown with its reliability score on a scale of 1 to 100.
