Top 10 Models in the 2015 Initial Quality Study

Top 10 Models in the 2015 Initial Quality Study

By Philly Murtha, June 29, 2015

The J.D. Power Initial Quality StudySM (IQS) measures the quality of new vehicles after 90 days. Both defects/malfunctions and design-related problems are measured, categorized, and analyzed. Good news this year is that new-vehicle quality rises by 3% from 2014, principally due to improvements in the quality of non-premium models and enhanced new-vehicle quality from Korean brands.

However, even with these quality improvements, entertainment and connectivity remain the most problem-prone areas for new car owners for a third consecutive year. "Smartphones have set high consumer expectations of how well technology should work, and automakers are struggling to match that success in their new vehicles," said Renee Stephens, vice president of U.S. automotive quality at J.D. Power. Yet, all 10 of the most problem-free new car, truck, SUV, and van models are offered with infotainment systems and in-vehicle connectivity.

In the gallery that follows, the 10 models with the fewest problems per 100 vehicles (PP100) as measured in the 2015 IQS are listed in order from the highest to lowest number of problems. Note: A lower PP100 score reflects higher quality. In the case of a tie, models are listed in alphabetical order.


10) 2015 Kia Cadenza (78 PP100)
The Kia Cadenza, introduced for the 2014 model year as the automaker's top-of-the-line sedan, is a large car that offers comfort and lots of features, including voice-controlled UVO eServices infotainment and Bluetooth connectivity. Considered by some to be an unpretentious front-wheel-drive (FWD) sedan, the initial quality of the Kia Cadenza outpaces higher-volume models in its segment, including the Chevrolet Impala and Toyota Avalon. Its overall score in the 2015 IQS improves by 3 PP100, compared with last year.


9) 2015 Kia Soul (77 PP100)
This boxy multi-purpose vehicle (MPV) earns an initial quality award in the Compact MPV segment for a fourth straight year and is among the 10 models with the lowest PP100 scores in the 2015 IQS. Additionally, the Soul improved by a significant 20 PP100 from 2014. Redesigned for the 2014 model year, the 2015 Soul is equipped with a telematics package that allows the owner to monitor vehicle activity when another driver is at the wheel.


7) 2015 BMW 5 Series (tie at 76 PP100)
