Visibility:power Window Devices And Controls 2016-11-21 · campaign 16V844000 · 4 vehicles
Defect: 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 Moto
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.
Fix: 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.
