"Owners report that Ford has been unable to fix the problem, even after repeated visits," it stated.
In 2014, Ford announced it was dropping Microsoft as the platform supplier for SYNC and moving to one based on Blackberry QNX for its SYNC 3 IVI -- a friendlier platform for mobile app developers.
This reporter reviewed SYNC 3 and found it an improvement on the previous version but also that the system was not as smartphone friendly as it was purported to be. At the time of its launch, iPhones owners still had to plug into their vehicle via a USB port to use mobile apps on Ford's AppLink system. Bluetooth wireless connectivity for mobile apps only worked with Android smartphones.
Last year, Ford rolled out a software upgrade to its SYNC infotainment system that lets iPhone users wirelessly access Siri Eyes-Free capabilities over Bluetooth.
While the upgrade enables users to make phone calls to contacts in their address book, ask for weather updates, select music to play, send and receive text messages via voice and get directions through Apple Maps, the system has glitches.
For example, when using it to look up phone numbers for points of interest, such as a restaurant, the system will find the phone number but fails to dial it on command.
The class-action lawsuit is expected to go to court sometime in 2017.
