Owner report 11517691 · 2023-04-18 (April 18, 2023)
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 hit with window or avoid being hit.

Owner report 11692340 · 2025-10-09 (October 9, 2025)
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. 15 years 150,000 miles. However, my vin and year w…
