   My vehicle began jerking, shaking and kept shutting off in a highway intersection. I looked on the ground after coasting into a gas station to find oil leaking from under my vehicle. I've never had an oil leak and it caused my starter to go and I've had to replace the camshaft sensors all within the same week. It appears the rear seal went after the cold streak we had. I need my vehicle to take my mother to treatments, etc. Is there any recalls on this?

The engines run rough and stall out WHILE DRIVING. GMC refuses to recall all of the vehicles with this problem and that includes my 2015 model year GMC…
