Chevrolet Spark

Issue: 
Over time, corrosion could cause the secondary hood latch to stick in the open position. If this happens and the primary hood latch doesn't engage or is released, the hood can open suddenly while driving. 
Note: This recall replaces 14456 (Transport Canada recall 2014-422). Vehicles repaired under that recall also require this repair. 

Safety Risk: 
A hood that opens suddenly while driving can block the driver's view and increase the risk of a crash. 

Corrective Actions: 
General Motors will notify owners by mail and instruct you to take your vehicle to a dealership to replace the hood striker assembly and hood latch assembly.

On certain vehicles, the sensing and diagnostic module (SDM), which controls airbag and pretensioner deployment, contains a software defect which may prevent the deployment of frontal airbags and pretensioners in certain circumstances. Failure of frontal airbags and seatbelt pretensioners to deploy in a crash (when warranted) could increase the risk of injury. Correction: Dealers will reflash the SDM with new software. In vehicles with any previous deployment events recorded in the SDM, the dealers will replace the existing SDM with a new SDM containing the latest software. Note: This recall affects 2014-2017 model year Sierra LD/Silverado LD models and 2015-2016 model year Sierra HD/Silverado HD model vehicles.
