The front passenger door handle doesn’t open then occasionally does! Any body experienced similar? Francis
What year car? If a couple of years old or older, Microswitch broken or out of adjustment or intermittent microswitch wire.
Door handle problems are common but easy to fix.
The likely cause is a faulty microswitch as "hammer" noted. I has the same problem and it was replaced under warranty.
Pressure sensors is faulty. If you are out of warranty, it should run you about $250 to get fixed.
