The Stuttgart-based sports car manufacturer announced today that 2,500 Euro-spec units of the Macan crossover are prone to brake booster failure. That shouldn't happen to a vehicle developed and built with world-class Germanic attention to detail, commanding a whopping €57,930 ($78,190) start price in its home country.
According to the informative letter outlining this quality assurance screwup, Porsche explains that following in-house QA tests, it has been discovered that brake boosters fitted to circa 2.5k Macans may have been damaged during the assembly process.

It's a widely known fact that Germans take pride in whatever work they do, so what exactly happened here? How was this error possible? Unfortunately, the carmaker hasn't offered an answer to this question, but informs customers that the "braking function nevertheless complies with legal requirements." Truth be told, it's certain that very few Porsche insiders are aware of how the stopping power glitch was able to happen.

For those of you that don't know what a brake booster is, let us explain it as simple as possible to clear things up: basically, it's a mechanically operated device attached to the brake system which multiplies the force applied by the driver's food to the brake pedal. Also dubbed as 'power brakes', the ensemble uses air, vacuum or hydraulic fluid to accomplish its purpose.

Porsche informs that the batch affected was predominantly delivered to customers in Europe. Naturally, all owners of the faulty Macan crossovers will be contacted directly by their responsible dealership service department, with inspection free of charge. If faults are identified, the ensemble will be replaced for free.

We have already tested the Porsche Macan in S guise and we found its sheer stopping power and swift responsiveness truly impressive for this type of car and the 1,854 kg (4,112 lb) weight it commands. During nasty scenarios requiring emergency braking, our demo car passed with flying colors each and every time.

We remind you that 2014 wasn't a great year in terms of quality and reliability for the manufacturer. First there was the fiery 911 GT3 (991) epidemic that forced Porsche to replace the engines of hundreds of cars. Secondly, who could forget Nick Murray's 'Nine-A-Lemon' nightmare?
