J.D. Power announced the results of its 2018 Initial Quality Study (IQS), stating that new-vehicle quality has improved for the fourth consecutive year—by 4% from 2017—and has reached its best level ever. Initial quality is measured by the number of problems experienced per 100 vehicles (PP100) during the first 90 days of ownership, with a lower score reflecting higher quality.
The Porsche 911 was named the best-performing model in the industry, with the lowest overall problem level (48 PP100) of any model this year. With an impressive 48 PPH, a 23-point improvement relative to 2017, this is the lowest level recorded in this generation of the study (2013-2018). 
"There’s no question that most automakers are doing a great job of listening to consumers and are producing vehicle quality of the highest caliber,” said Dave Sargent, Vice President of Global Automotive at J.D. Power.
