My Ascent started making a ticking noise that I assumed was valve or injector related. I took it into the dealer who found a crack in the exhaust manifold. Thankfully I bought the extended 100,000 warranty however it has been nearly three weeks and the local dealer can’t find the part. They claimed to have escalated the matter, but as of today they still have no idea on the status of part. Two questions… has anyone else had the manifold crack? And what has been your experience getting replacement parts? We all know the supply chains were terrible last year but I would have hoped things had improved by now???? I am contemplating replacing this Ascent next year but given the poor service at my local dealership, I am also considering changing brands.
