10 of the Auto Industry’s Most Unreliable Vehicles

Consumer Reports’ annual auto issue finds poor reliability in a multitude of used vehicle models. Here are some of the worst offenders.
  • Car buyers have myriad reasons for selecting one model over another, but for many consumers, reliability is paramount. No matter how powerful a car’s engine or how beautiful its styling, breakdowns are unacceptable.

    That’s why, every year, Consumer Reports combs through more than a half-million owner surveys to help characterize the reliability of virtually every major vehicle. Arguably, they’re the best at it, largely because their massive data sets come from the users themselves. Moreover, the information is broken down to cover all major sub-systems, such as engines, transmissions, suspensions, electrical and electronics, among others.

    In years past, Consumer Reports engineers have repeatedly told us that glitzy new technologies are one of the biggest causes of unreliable vehicle performance. “The manufacturers that do better are more conservative in their approach to rolling out new technology,” Jake Fisher, director of auto testing for Consumers Union, told Design News last year. “They systematically introduce their technologies bit-by-bit, rather than making big, across-the-board shifts.”

    The underlying message is that the “yawners” – vehicles that draw less attention from car buff magazines – tend to exhibit better reliability. Why? Because they more often employ proven, bullet-proofed technologies.

    Here, we offer a peek at some of the cars that haven’t fared well in Consumer Reports’ studies of used vehicles. We’ll leave it to you to decide why. From Chevys and Cadillacs to Fords and Chryslers, following are snapshots of some of the auto industry’s biggest offenders.    

  • The Fiat 500 has been a repeat offender, receiving “much worse than average” reliability ratings from Consumer Reports in multiple years. Problem areas for the 500 include transmission, drive system, suspension, brakes, noise, paint, trim and power equipment. (Image source: Fiat Chrysler Automobiles)

  • In the 2014, 2015, and 2016 model years, the Chevy Suburban received an overall rating of “much worse than average.” Its most problematic areas were in-car electronics, power equipment, body hardware and noise/leaks, according to Consumer Reports. (Image source: Chevrolet)

  • Many vehicles don’t exhibit problems in their first year, but the Tesla Model X has had reliability issues from the get-go. In-car electronics, power equipment, body hardware and climate controls were the big culprits in its only year of data. Consumer Reports’ prediction for 2017: much worse than average.

  • The Dodge Durango sport utility vehicle received an overall owner reliability rating of “much worse than average” in 2012, 2013, and 2015. Engine cooling, drive system, suspension, power equipment and in-car electronics were its biggest problems, said Consumer Reports. (Image source: Fiat Chrysler Automobiles)

  • In the four model years from 2011 to 2014, more than 3% of Ford Fiesta owners complained of major and minor transmission problems. Other problem areas included drive system and suspension. The Fiesta received an overall Consumer Reports “much worse than average” rating in four of the five model years between 2011 and 2015. (Image source: Ford Motor Co.)

  • The Ram 2500 full-size pickup exhibited numerous problems between 2012 and 2015, including fuel system, suspension, brakes, exhaust, paint/trim, and power equipment. It received “much worse than average” overall ratings in 2012, 2014, and 2015 – the only years when it was rated by Consumer Reports. (Image source: Fiat Chrysler Automobiles)

  • Going all the way back to 2009, used Volkswagen Jettas have exhibited a multitude of problems, the most prominent being the fuel system. Other problem areas include climate system, noise/leaks and power equipment. Consumer Reports has assigned the Jetta a “much worse than average” rating in four of the last eight model years.

  • The Cadillac ATS received poor owner reliability ratings in 2013 and 2015, largely on the basis its climate system, in-car electronics and power equipment. Consumer Reports also gave it a “much worse than average” new car prediction for 2017. (Image source: Cadillac)

  • The popular Jeep Grand Cherokee keeps getting dinged by Consumer Reports year after year, with little change. It received the lowest overall reliability ratings in four of the last seven years it was evaluated, dating back to 2009. Problem areas are all over the board, from transmission and fuel system to electrical, suspension, power equipment and in-car electronics. (Image source: Fiat Chrysler Automobiles)

  • GM’s highly-publicized Chevy Volt earned average reliability ratings in its first few years, then dropped sharply during the past two. Problem areas include its drive system and in-car electronics. The bigger issue, though, is that Consumer Reports gives a “much worse than average” new car prediction to the Volt for 2017.

OK, thanks for the ad-blocker tip. Unfortunately, it seems our company internet proxy server has a built-in ad-blocker which I have no influence over. IT control that. So I can't read the articles from the deisgn news website any more.. It's the only site I have problems with.
