door ajar alarm and door locks go on and off while driving

Spray some WD40 with straw into each door latch worked for me.

I will definitely try it. My mechanic said it was the battery. I bought a new battery, it stopped for about a month.And mine goes off in the morning also. I'm driving to work and lights are flashing, and brake indicator flashes on then off.Looking to trade about middle of January..
