I have had 2 experiences so far that the hood latch pops for no apparent reason, however I wasn't sure the first time that I hadn't accidentally pulled the hood release somehow. This started me to routinely check to make sure the hood was securely latched before driving. The time that I am reporting was an occasion where, after having driven 2 hours on the interstate at 70 mph, I pulled into the driveway and discovered that the hood latch had again released sometime during the drive. Thankfully the secondary latch held!
