2014 GMC Sierra. Consumer writes in regards to vehicle electrical panel froze while driving. Also, the power steering locked up, the headlights did not work properly and the alarm sometimes sounded after the was removed from the ignition. Also, the engine light illuminated. The vehicle was taken to the dealer twice. However, the problem was still not resolved. There was a hesitation/lurch coming from the transmission, and an issue with the tire pressure monitoring system. The instrument panel malfunctioned on the way back from the dealer. The check engine light, illuminated sporadically. Updated 07/10/14 the consumer stated there was a steering issue, as well. The dealer was unable to replicate the problems. Updated 08/06/14.

I had my truck's ecm reprogrammed last Friday (1/17) due to recall #14v007, and earlier this evening (1/24) the check engine light came in and the dic showed an "engine power is reduced" message. The engine ran very sluggish and I parked it as gm recommended to do in their recall letter. This is the second time this has happened now. I thought that the new software was supposed to correct that issue?.
