Intermittent Alarm or Hood Ajar Message
Diagnose and fix an Intermittent Alarm or Hood Ajar Message on Chevrolet Equinox and GMC Terrain
A faulty hood latch may be the cause of an Intermittent Alarm or Hood Ajar Message on 2013 Chevrolet Equinox and 2013 GMC Terrain vehicles built before 9/5/2012 GM has issued a service bulletin #PIT5176B to address this issue.
The problem may show up as an Intermittent “Hood Open” message displayed on the Driver Information Center (DIC). Or, the vehicle’s alarm system may activate intermittently, sounding the horn. Or, the remote start may activate.
If you cycle the IGN key to off and then back to RUN, the Hood Open message may disappear. Adjusting the hood latch may work for a short period but will NOT solve the problem permanently.
The Intermittent Alarm or Hood Ajar Message is caused by moisture in the hood latch switch
GM has redesigned the hood latch with a more durable and water resistant hood latch switch. Obtain the new parts and install to correct the problem.
