Germany
From the German perspective a product should never break down. It should be 100% reliable. Not only the German engineer thinks this, but also the German consumer. Germans are perfectionists. A reliable product, like a reliable person, delivers on it promise.
United States
For Americans a reliable product functions well under adverse conditions. If it has problems, the supplier reacts promptly with good service, at minimum additional cost via the warranty, and at minimum inconvenience by offering a replacement product.
