Lionel 21" car kinematic coupler centering issue

I had this issue with my first run of cars and just switched them to Kadees.

Is anyone finding that the kinematic couplers on the new Lionel passenger cars are not centering? I push or pull the cars on straight track until the coupler is centered. When the locomotive beings to pull, the couplers go off center badly regardless of speed. When the cars come out of a curve the couplers remain uncentered. 

Of course I know that there is a "point" that the coupler centering plate must navigate and the coupler then chooses left or right, but off center looks terrible and cannot be photographed. I assumed that coming out of a curve or on straights, the coupler would recenter. My curves are all 72" and larger. 

Anyone seeing this? Any solutions?

We had the same issue with a set of freedom train cars.  Our club had a show over last weekend and they started off just as you described.   However, after a weekend of running them and switching them in and out of the yard.   The couplers seem to be working as designed now with no issues.   We didn’t even lubricate the kenematic parts.  Which I’m sure would help with this even further.   They work very nicely now.  My suggestion would be to run’em for a good bit you might be surprised how well they work in.   I also had a smililar issue with my Milwaukee road s3.   It always worked well but after logging some miles it works beautifully now.

That was my thought.  Maybe a little lube will help too.  A little.  The PRRs are on the shelf at the LHS and they really are a beautiful set of cars.  It sounds like they were sold late in the day Saturday so I won't have a chance to look at them closer. Thanks for chiming in.

Good advice from all of you. Many thanks. I appreciate the different approaches and I will now to a very light lube. The coupler mechanism does feel a bit tight. I agree that running will loosen them up.
