Hi Ktrasher, do you work with that law firm? The rear main seal on my 2016 Equinox blew out on Dec 10, 2019. Ilive in Minnesota, and the temperature was -6 that day, so I strongly suspect the PCV valve froze. I'm going to give them a call on MondayPosting for others that might be having the same issue. If you have had any problems with oil consumption, timing chain, pistons, or PCV valve issues please call the class action office at 310-474-9111. There has already been a settlement for a variety of Chevy and GMC models but mine (a 2014 GMC Terrain) is not included. Feel free to private message me if you have any questions. The more that call the more they have a case. There has already been a settlement for several other GM vehicles so it may not be that hard to get additional vehicles covered.
