I'm experiencing fuel management system failures on my 2013 Silverado. Always use Dexos oil and my traction control light, anti skid and check engine lights come on and after taking it to get the code read it says I have o2 sensor issues. I took it to a mechanic and he said that's not the issue at all it is with the flawed engine design from the lifters not getting proper lubricant when switching over to fuel management mode. They gall and start sticking and It also causes motor Skip. It stalls and accelerates on its own. I have called and reported this to GM and Hwy safety. Is there a recall setup for these motors? The mechanic has done several of these in the past few weeks on the same type motors. This truck is way too expensive to be experiencing this. very frustrating. Any help or suggestions is appreciated!!
