NHTSA Complaint #11578084 — 2017 CHEVROLET EQUINOX

I was driving when my car started knocking. I pulled over on the highway and noticed oil all over the undercarriage of the vehicle. I immediately drove to the dealership and had the mechanics take a look. They came back and said, "The rear main seal was leaking due to a plugged PCV port that froze because of the cold weather. This caused high crankcase pressure to build, which blew out the rear main seal." Looking online, I found that this appears to be a common problem. The dealership said they could fix it by drilling the hole in the PCV port bigger, but there is currently no recall on this issue. Just to replace the seal, they are charging $2500, with an additional few hundred dollars to enlarge the PCV port. Thankfully, I was able to pull over and get it to the dealership. I can only imagine how bad things could have been if I hadn't been in a relatively safe spot.
