The auto industry has learned to handle recalls in a straightforward, professional manner. It has not figured out how to handle the faults that are more apparent than real.
Audi is bringing nearly one million cars back to fix two airbag problems in a flawless recall. Once that event would be considered a terrible public smear, like garbage dumped on a new suit. Today, Audi is only brushing a bit of dust off its trousers.
The secret is honesty and speed in addressing the problem. The Japanese government is fining Fuji Heavy Industries for delaying a recall of Subaru cars there. Fuji tried downplaying a problem.
The difficulty with the Audi 'unintended acceleration' issue in the USA 10 years ago was that it wasn't real. It was a ghost problem. Audi tried to explain it to the public, but the public didn't listen. Experience shows that is difficult to teach people.
Mercedes may have a ghost problem with its A-class roll-over.
Whether a vehicle is top-heavy and liable to roll over is a matter of physics. Trucks have high centers of gravity, and their drivers must take that into account when cornering. Cars generally cannot be rolled over on a flat surface. They lose their grip and skid first, and hot rod journalists know this.
It is possible that the A-class only rolls over when stunt drivers or journalists go to extremes that no car is designed for, and it is possible that the design has truck-like, unstable elements.
Mercedes is trying a new approach to the public concern. The quick response of changing tires and adding electronic traction devices is likely to please customers. At the same time, the company maintains that the A-class is not an unsafe design. Time will tell if Mercedes has the right answer.
