Owners have filed 22 complaints with NHTSA about the 2016 Cascada. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2016 Cascada over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
General Motors LLC (GM) is recalling certain model year 2016 Buick Cascada vehicles manufactured December 1, 2015, to February 24, 2016. The affected vehicles may have had the original convertible roof control module (CRCM) replaced with an incorrect CRCM, that allows the windows to close automatically when the roof is closed and can allow the windows to be closed remotely from distances beyond 11 meters using the key fob. As such, these vehicles no longer meet the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 118, "Power-Operated Window Systems."
Risk: If the windows close automatically or can be closed remotely in ways that do not meet all the requirements of FMVSS 118, the unexpected closure can increase the risk of injury to the passengers.
Remedy: GM will notify owners, and dealers will replace the CRCM with correct module, free of charge. The recall began on December 1, 2016. Owners may contact Buick customer service at 1-800-521-7300. GM's number for this recall is 16126.
Carmakers sent NHTSA 985 service bulletins and notices that cover the 2016 Cascada, the latest on Sep 26, 2026. They tell dealers how to fix known issues.
The parts they mention most: equipment (426), electrical system (197), engine and engine cooling (101), engine (88), power train (73).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
