Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The rear glass window is lifting on the bottom left corner. My husband just noticed it one day. A service bulletin was released by GM in november, 2019 regarding this issue. My insurance won't cover it as it was not caused by an outside force. Safety hazard: if I drive with my windows open and top up, I'm afraid the pressure will cause the window to detach, which would injure any vehicle behind me. This should be a GM recall. The glass can not be replaced without replacing the entire soft top.”
NHTSA complaint #11339734, filed 2020-07, 36,000 miles“My convertible top is not lining up with the windows. When it rain water on the floor . U don’t see where it’s coming from . I just see large amount of water”
NHTSA complaint #11580207, filed 2024-03“My back window glass on convertible too is coming unsealed from the convertible top, if I pay to replace the top this has been reported 6 times already, and will happen again. Pointless to pay $3,000 dollars to have my top replaced. The glass is going to end up coming completely unsealed and fly off and hit someone’s car and cause an accident. My car has low milage and is financed under a reputable Buick dealership. This needs to be recalled immediately! The pictures I submitted are from a week ago, and the glass is now even more separated from the fabric.”
NHTSA complaint #11450750, filed 2022-02“The back window is coming away from the fabric top. Had been getting worse for months. I have complained to GM. I was told to take my car to dealership I did that months ago, when I still had warranty. Nothing was done. I have taken it again to dealership because the window is coming out more. I now have to get it fixed and I have to pay a portion of the cost of a new top, since the window cannot be put back properly. I am mad that the dealership would not help when it first started and that mow. I have to pay some now that I am out of warranty.”
NHTSA complaint #11378152, filed 2020-12“The back window on the convertible top has separated from the fabric. Buick dealership said it was not a covered item under the extended warranty. We tried to glue it back down but it keeps separating all around. Dangerous situation because it could separate completely during travel and cause an accident/injury to others. Should be a recall item since it is being reported by several other Cascada owners.”
