2012 GMC Terrain Available Features: Cons
Year	Comment
	The GMC Terrain gains some desirable features for 2013, including a well-featured, easy-to-use "Intellilink" infotainment system. Pairing a phone doesn't get quicker or more painless, and Pandora is seamlessly and thoroughly integrated. New safety features (all standard on the Denali) include forward collision alert (useful), blind sport warning (useful), rear cross-traffic detection (useful), and lane departure warning (not; most people, annoyed by frequent unneeded beeps, will likely turn it off). The problem is, the Terrain Denali lacks many features buyers might expect at its price (more on this later). * xenon headlamps * steering-linked headlamps * rain-sensing wipers * adaptive cruise control * keyless ignition * power steering column adjustments * heated steering wheel * dual-zone climate control * rear seat air vents * auto-up for at least the driver’s window * cooled front seats * heated rear seat see full GMC Terrain review
