Has anyone had problems with their drivers side seat belt not staying buckled? Even though I tug on the belt it feels latched. But 5 - 10 min later, the belt is unlatched. Any thoughts?

It stays if I plug it into the passenger side latch.

 

I can't say i have. I did ck for TSB's and there are none. You may need to replace the buckle assy. You may want to call the dealer and find out if there can still get them. For your safety i would buy the buckle assy thru mopar and no one else.

 

Two thoughts (opinions) - (1) worn mechanism or (2) dirty mechanism.

Using the passenger buckle was a good diagnositic check - works there so the driver's seat belt (tongue ?) should be good, leaving the buckle itself suspect.

Does the driver's release button function the same [force required to depress for release? With no belt installed, do both buttons release the same (snap back) way?].

If the driver's behaves differently than the passengers (front or all), some dirt may have gotten into the driver's mechanism. If you would try to clean it, make sure it does function correctly afterwards.

If it is worn, make sure you get a good OEM replacement. Let us know the outcome.
