Also, the accompanying press release says:
"The Audio/Communication/Entertainment/Navigation (ACEN) category continues to be the most problematic area, accounting for 22% of all problems reported—up from 20% last year.
For a third consecutive year, the problems most reported by owners are Bluetooth pairing/connectivity and built-in voice recognition misinterpreting commands."
... so yeah, many problems reported are probably not even related to the primary function of the vehicle (and dare I say, some may even be due to user error on the part of those who are less tech savvy).
