About maybe 2 months ago my tailgate open light comes on. When the exterior light is left on when I get in the car. .. it will go out but the tailgate light open will come on while driving and you will a ding then the light comes on while drive ng. As a result the car alarm.gs.off several times. I have checked the tailgate and it is closed I have taken it in but they can’t find the reason why this happening. I have been on other forums and this appears to have been a problem.with.other Acura 2008 MDX,s.
