On a recent road trip, after an hour of driving, the “hood open” light came on and beeped continuously for about an hour. Pressing “clear” stopped it for a short time. We stopped to check the hood and it was not open. We opened it and shut it again. the light and beeping kept up for a while then finally ended as suddenly as it started. Three or four days later the same thing happened although not for as long. It has now been two weeks and it hasn’t happened again. Any ideas what’s causing this?
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.
