Iam just reporting several known issues. First, with code P2138, which I got today at Oreilly after my car started throwing warnings. I used my parking brake briefly and afterwards got the following warnings on my car: aœSteering Assist is Reduced, Drive with carea, aœEngine power reduceda , aœPropulsion Power is reduceda , aœService Parking Brakea. Iave never even had one of these warnings. Iave only gotten aœshift to parka which is another known & common issue. With this P2138 code, it can affect acceleration and essentially loss of control over it, but seems I suddenly have several issues. Recently the infotainment system is possessed, touch screen stops working, it calls people by itself, beeps and scrolls by itself and is essentially useless. Might as well be driving at 1997 something or other, at least I could play a tape or CD. This is Denali trim at 87K miles. Primarily though Iam concerned with this code, if itas legit, it is very dangerous. How unreliable and unsafe to not know.
