The vehicle transmission gets stuck and doesn't always shift from first to second gear. This results in being unable to accelerate past 20-30 mph upon takeoff which is scary and dangerous on the highway. My mechanic shop has informed me that the automatic transmission control module (tcm) needs replacing. On 10/14/2016 there was a recall notice for the tcm on several vehicles including the 2010-2013 Chevrolet Equinox. Gm's recall numbers for this are 50490 and 50491.
