Visibility/Wiper	14.5% ODI 11582433 The rear window on the Cascada is known to separate from the convertible top material, likely due to an insufficient amount of primer used during the assembly process, which creates stress points allowing the material to separate from the glass. Once this bond has started to fail, it is eventually going to lead to the glass completely falling off the car. It is likely that the glass separating could render the rear defrost inoperable, too, decreasing visibility. NHTSA bulletin 17-NA-216 describes this problem; why was no recall ever issued?

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.

Look up ODI 11718797 at NHTSA ↗ ODI 11718833 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. Look up ODI 11718833 at NHTSA ↗

They would not reimburse me as it expired and car was repaired by a third party. We had only put 500 miles on it since purchasing. It was the Valve Cover Gasket. As we are on a fixed income with a car under 50k miles, this was a big hit for us. Look up ODI 11765093 at NHTSA ↗

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
