   After owning for a year, it started idling very rough. Took it to a shop and there was a GM Service Bulletin issued on these cars N192291620 that expired on 6/2026. 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.

   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.

8. Filed Dec 11, 2024Failure Jul 31, 2024Canyon, TXSeat belts

   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?

12. Filed Mar 9, 2022Failure Feb 21, 2022Janesville, WIUnknown or other

    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.

    I PURCHASED MY 2016 BUICK CASCADA IN 2017, IN THE SUMMER OF 2018 I NOTICED THE PAINT CHIPPING OFF ALL 4 OF MY RIMS. THEN IN DECEMBER OF 2020 I NOTICED THE BACK WINDOW STARTED TO BECOME UNATTACHED FROM THE CONVERTIBLE TOP. THE VEHICLE IS NOW OUT OF WARRANTY AND THE DEALERSHIP TELLS ME I NEED TO REPLACE THE ENTIRE TOP, WHICH IS ABSOLUTELY RIDICULOUS. I PAID $38,000 FOR A VEHICLE THAT IS FALLING APART. I DON'T UNDERSTAND WHY GENERAL MOTORS IT'S NOT HELD RESPONSIBLE FOR THIS?

    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.

    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.
