I have 55,000 miles on my '14 Impala. It started separating at the seam in the drivers seat bottom. It's separating where the seat itself meets up with the little protrusion at the front of the seat. Anyone else had trouble with the seats separating at the seams? Of course it's not under Warranty, but I dont think a seat should be coming apart at this time. This is just another problem in a big list Ive had with this car. The seat heater has also gone out in the same seat. I don;t think I'll be looking for another Chevy after this one.
