Looks like GM just added 14 new models for the 2010 Mobile app.

OnStar today added 14 Chevrolet, Buick, GMC and Cadillac vehicles from 2010 that allow users to download vehicle data and more to their mobile devices.

The expanded list of 2010 model year vehicles includes the Cadillac DTS, Escalade, Escalade ESV and Escalade EXT; the Buick Enclave and Lucerne; the GMC Acadia, Yukon, and Yukon XL; and Chevrolet Avalanche, Impala, Suburban, Tahoe and Traverse.

OnStar customers are increasingly using their smart phones to remotely check fuel levels and tire pressure, start their vehicles and make sure doors are locked via OnStarís mobile app, according to data released today from the company. Drivers of the Chevrolet Cruze and Silverado use the app most frequently.
