| Description of the problem | The car ran out of brake fluid - there was an indicator and when taken to service we were told the reservoir was empty. What is alarming is that the car is serviced very frequently and one set of brakes was recently replaced (about 6 months). Moreover the dealer stated there was no leak. They stated that they do not replenish the brake fluid when replacing pads, in essence, because the fluid system is so fragile and they are afraid they will do more harm than good. It seems like a straightforward proposition that if the brakes are checked and pads replaced frequently, and there is no leak, there should be no possible way for the fluid to go empty absent a defect in the car (excess fluid consumption for some reason besides a leak) or faulty maintenance procedures. I believe the practice of not replenishing brake fluid - described to me as the normal practice at mercedes service, not a 1-time mistake - is negligent. Contributing factors include (1) mercedes brakes are known to wear very quickly (roughly annual brake pad change); (2) the 2014 model adaptive cruise system tends to apply the brakes very often, i. E. Unintelligent algorithm that uses brakes continually while cruising at 70 mph on freeway, not something a human would ever do |
