Subject N202311160 — Drivers May Overlook Open Hood Alerts
Models 2020 Chevrolet Corvette

Release Date: September 2020

Revision: 01

Revision Description: This bulletin is being revised to add the customer letters. Please discard all previous copies of N202311160.



It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.

Vehicles involved in this recall were placed on stop delivery August 18, 2020. Once the service procedure contained in this bulletin has been performed on the vehicle, the vehicle is released from stop delivery and the vehicle can be delivered to the customer.

All involved vehicles that are in dealer inventory must be held and not delivered to customers, dealer traded, or used for demonstration purposes until the repair contained in this bulletin has been performed on the vehicle.

Involved vehicles will be repaired either through dealer repairs as described in this bulletin or through over— the— air (OTA) programming. Dealers can and should perform the procedure in this bulletin on any vehicle with an “open” status on the Investigate Vehicle History (IVH) screen in GM Global Warranty Management system. Due to the fact that vehicles will be closed in IVH through successful OTA programming, dealers should always check the status in IVH before performing any vehicle repairs.




Model Year










Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.


General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2020 model-year Chevrolet Corvette vehicles. If drivers ignore the vehicle’s visual and audible warnings that the front trunk lid is open, they can drive the vehicle in that condition at speed, which could increase the likelihood that the wind force is sufficient to inadvertently flip open the hood. If the hood is open (i.e., the primary and secondary latches are not engaged) while driving at speed, the hood could flip open and obstruct the driver’s forward view, increasing the risk of a crash.


GM will update the software in the vehicles’ Body Control Module (BCM) to limit vehicle speed to 26 mph when the hood is not completely closed and latched. The software update will also provide a DIC message indicating that the top speed is limited to 26 mph. In addition, the operation of the hood release on the key fob will be modified to reduce the likelihood of inadvertent hood release actuations. The interior door trim switch and release button located inside the front trunk compartment are also modified to require a longer press-time. Owners who have accepted applicable terms and conditions will have the opportunity to accept these software changes using wireless over-the-air (OTA) technology without having to bring their vehicle to a dealership. Alternatively, owners may schedule service at a GM dealer to receive these software updates.
