DETROIT -- How do the quality ratings for the 2017 Tesla Model S and Model X compare to competitors?
They don't, based off J.D. Power's 2017 U.S. Initial Quality Study that was released Wednesday. That's not because Tesla Inc. doesn't make quality vehicles, but because it doesn't allow J.D. Power access to its customer registration data for the survey.
"I don't know that they're hiding anything. They just don't want to participate," Dave Sargent, vice president, global automotive at J.D. Power, said when releasing the annual survey results here at an Automotive Press Association meeting. "It's not like their cars are falling apart."
For the annual study -- which started 30 years ago -- J.D. Power collects customer registration data from each state. It uses that information to send surveys to consumers who have leased or purchased a new vehicle for that given model year to report any problems they may have experienced in the first 90 days of ownership.
But some states, including Tesla's home of California, require automakers to grant state officials permission to release the data.
All automakers aside from Tesla have granted such access, according to Sargent. J.D. Power, he said, receives about 30 percent of Tesla's customer data. That amount is not enough for the company to place the automaker in its Initial Quality Study, which is viewed as an industry benchmark for quality
