My 1993 Lexus SC400 had the easy exit feature, which actuated the steering wheel, seat and folded the side mirrors. There was never a problem.
My son is driving that car now some 24 years later and 350K miles. None of those systems have failed. His driver window regulator did fail once however. But that was not associated with the easy exit feature.
A word of caution, if you are in the north where ICE can form on the car you may want to disable the folding side mirror option on the S. A friend of mine stripped his mirror gears on his S due to a heavy ice buildup.
