Does anyone else have an issue of noisy door check straps? For those who don't know what I'm talking about, it's the black bar attached between the door and body of the car within the door jamb that limits how far the door can extend. Since owning this car brand new, I have followed the instructions down pat found in the user manual of periodically lubricating the door jambs with the required lubricant officially from GM. Well, after long rain storms and humid weather, they become loud and squeaky again! I even had to replace the drivers side front doors check strap because of it making a very loud popping noise each time it reached a detent which holds the door in place. The squeaking usually occurs when each detent is about to be engaged or during engagement. I'm afraid all doors will eventually be making loud popping noises and these things will have to be replaced as "regular maintenance". Absolutely pathetic! What is wrong with these? Anyone please give some advice. Thank you.
