Issue: 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.

Complaints are self-reported and skew toward problems people find alarming, so read this as where to look rather than as a defect rate.
The contact owns a 2016 Buick Cascada. The contact stated that while driving at an undisclosed speed, the vehicle made an abnormal squealing sound. The vehicle was subsequently taken to the dealer, where it was diagnosed with a PCV valve failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 19,000.
Buick Cascada back window on the convertible tops coming apart, causing flooding inside the car, also there's a danger the window will come out driving down the road. Buick refuses to do anything.
The rear window of the convertible top starts to pull away from the top itself. Could separate and displace entirely causing damage or injury behind.
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.
See attached document for complaint.
The contact owns a 2016 Buick Cascada. The contact stated that when his wife entered the vehicle, the rear passenger’s side window automatically rolled down when the vehicle was started. The contact was unable to confirm if any warning lights were illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 16V844000 (Visibility). The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The failure mileage was approximately 80,000.
The motor is out of the seat belt presenter on the driver's side. It does not present and makes a horrible sound. This part was ordered in July, 2024. I've contacted the dealer and Buick directly to find out when I can expect the part to be replaced. They've told me that the back is on an extended back order. I asked if the part could be replaced with a used part. They told me that because it's a safety-sensitive part, it has to be replaced with a new part. But this part has been on back order for months with no delivery in sight, and they expect me to drive my car like this with this "safety" issue compromised.
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?
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
The contact owns a 2016 Buick Cascada. The contact stated that the rear windshield glass had begun to separate from the convertible top headliner. The contact attempted to repair the failure by using epoxy glue, but the failure returned over time. The contact took the vehicle to a dealer where she was provided a quote to replace the top. Upon investigation, the contact discovered a service bulletin Manufacturer Communication Number: 17NA216 which she linked to the failure. The manufacturer was notified of the failure but provided no assistance. The vehicle was not repaired. The failure mileage was approximately 80,000.
My rear window of my car is becoming unglued from the top. I talked to the GM dealership nearby, and they told me I needed a new top. There was a memo put out in 2019 stating that this was happening due to not having enough primer from the manufacturer. This is a safety hazard. If my window falls out, it can create a crash and harm any vehicle behind me. If GM knew this part was bad because of a manufacturer, they should be liable to fix the problem.
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.
