My c-max has keyless entry (pushbutton ignition). In the last 6 weeks, on the driver side, sometimes the car will not lock when you touch the black pad on the handle. On the passenger side it always works. The unlocking on the driver side works fine. Just sometimes the lock won't respond to touch.
I've replaced the battery in the fob. No change. Holding the fob close to the lock to make sure there is no interference makes no difference.
I've tried to figure out if it's weather related. It seems like maybe it does it a little more during rainy weather, but it also does in on sunny dry days.
It doesn't happen often enough that I can demonstrate it for the dealer. I can't make it happen. It just does it every now and then. But when it works, I can sit there and lock / unlock for 20+ times without a problem. Then I drive somewhere and go to lock the car and it won't lock by touch on the driver side.
When it won't lock, if the car is then locked from the passenger side or from the fob button then it starts working again. I push the button on the fob to lock. I can then unlock and lock by touching the handle with no problem.
Anyone have any similar experience or any thoughts?
