PCV Failure at 62,000 miles. GM extended warranty on 2016 models that demonstrated this problem. Appears to be a design flaw and often fails again after repair. $2000 + job to repair

While driving down the highway my vehicle decreased in power and then I heard a loud whistle or whining sound. Upon examination at the dealership, they determined that the PCV system had failed. The positive crankcase ventilation system caused my Camm to leak and created a vacuum leak which blew out the seals of my vehicle. Upon further investigation I found that GM was involved in a class action lawsuit for the 2016 models and that an extended warranty was given for 2016 -2019 Cascada models.

17-NA-216 was originally issued in in 2017 updated in 2019 to include 2018 model. Back windshield detaches from canvas/folding top. Was concerned primarily about safety of my child who drives car that windshield would completely fly off when driving. I replaced the folding top cover per bulletin. GM refused to reimburse stating not recalled since not safety issue. I disagree. Damage it could cause if flys off while driving could cause an accident for driver or other cars on the road who are h
