Consumer Reports’ 10 Most Unreliable Cars of 2016

It’s not always easy pinning down exactly what makes an automobile unreliable, because between harsh environments, poor driving habits, and the occasional lemon or two, a lot can go wrong without there ever being a recall on the automaker’s end. Every year we look forward to hearing what Consumer Reports has found to be the least reliable cars on the market, because for as high-tech and well-made as automobiles are these days, there are more things that can go wrong with them than ever before.

By obtaining reliability data from an annual questionnaire that it sends out to subscribers on and via Consumer Reports magazine, the buyer watchdog was able to garner responses regarding over half a million vehicles from the Consumer Reports National Research Center in the spring of 2016. The questionnaire asked subscribers to note any problems that had occurred within the past 12 months of ownership, and then requested the identification of any issues that may be considered serious due to cost, failure severity, safety concerns, or downtime.

They then asked subscribers to include problems that were covered by warranties, excluding anything resulting from accident damage or issues stemming from recalls. This gave respondents the ability to check off problems from a list of troublesome areas, as everything from the engine and transmission, to the car’s climate controls, brakes, electrical system, and power accessories were placed under scrutiny.

All of the following vehicles have their merits in one form or another, but Consumer Reports has never been known for overlooking issues either. Trusting an investigative write-up is a great way to figure out what could go wrong with a particular chassis prior to purchase. Here are 10 of the least reliable cars of 2016 according to Consumer Reports, many of which are prone to all manner of mechanical and technological malady.

1. Chevrolet Tahoe/GMC Yukon

Being practically the same vehicle means that both the Tahoe and Yukon suffer from the same maladies. For as capable, tow-ready, roomy, and tech-filled as they may be, Consumer Reports found these SUVs to be prone to premature problems with steering vibrations, power equipment, and in-car electronics. We suggest looking toward Buick as a GM alternative, which scored stellar reviews with Consumer Reports this year, beating out many European and Asian competitors for quality and reliability.

2. Ram 2500

Despite its clever, auto-leveling air suspension, potent Cummins diesel engine, and notable towing capabilities, for whatever reason the Ram 2500 gets slapped with all sorts of reliability complaints while both the 1500 and 3500 series go relatively untouched. Issues with the Ram 2500 range anywhere from strange steering vibrations and problems with emissions controls and sensors, to faulty 4WD components and power equipment that is prone to premature failure.

3. Ford Fiesta

This hot little subcompact has all kinds of trouble spots, as even the sensational ST model gets dinged for problems with clutch replacements, rough-shifting or slipping transmissions, excessive noises and leaks, and power equipment complaints. Manufactured in Mexico, and utilizing parts sourced from around the world, the Fiesta continues to earn rave reviews with critics, but bottoms out with buyers due to reliability woes.

4. Fiat 500L

Consumer Reports rips into the Fiat 500L, accosting it for earning a “dismal road-test score, thanks in part to a stiff ride, flat seats, and an odd driving position.” Owner satisfaction also remains low, meaning a strong percentage of buyers wish they had purchased something else, and with the 500L retaining the title for having one of the worst reliability scores today, you can see why few people find it to be the perfect hatchback. It also landed a “Poor” rating from the Insurance Institute for Highway Safety (IIHS) for small-overlap frontal crashes, and is notorious for having complaints pertaining to its transmission that is prone to slipping and locking-up, as well as power equipment headaches, drive system issues, and in-car electronics glitches.

5. Tesla Model X

It may look like it’s straight out of the future, but the Model X from Tesla is a disaster when it comes to reliability and practicality. Those massive, Falcon-wing rear doors may look cool as they swing up and out of the way, but they also are slow as hell when it comes to opening and closing times, and unlike every other multi-rowed car on the market today, the rear seat back doesn’t fold, thus removing the word “utility” from the vehicle’s Sport Utility Vehicle classification. Consumer Reports finds that buyers have also run into trouble spots with the SUV’s locks and latches, power equipment, on-board electronics, and climate system.
