Nah. Google an engineering principle called the bath tub curve. It's a graph of the failure rate of items over a period of time. Essentially, for a batch of the same products, those that are lemons will fail early on in the products life cycle, resulting in a high failure rate intially. Thereafter the failure rate drops markedly and for a period of time the rate is low and flat. However, after a few years pass, the rate of failure picks up rapidly as items age and simple mechanical failure due to stress and fatigue kicks in.
Thus, one can expect failure rate to increase after an item becomes "old" - not decrease. of course, if you buy in the period when the graph is "flat" then you should have missed most of the lemons - but you are closer to reaching the time when simple age starts causing failures.
