while driving on the highway/freeway system in the Portland Oregon area on several occasions one of which i initiated myself activated the cruise control immediately after initiating the vehicle began to increase its speed to the continuing to speeds well beyond the 100 mile per hour mark I was not able to deactivate the cruise control in the usual ways pressing the brake pedal did not work cruise control knob has a cancel that was not responsive either on two other times this happened when I while driving the same thing happened but i was un aware i had touched the cruise control knob one of which a friend of mine was driving and i failed to notify the individual to be extremely careful not to use cruise control he had initiated by accident since it was so close to the blinker control switch He had more strength than i did and managed to bring it to a full stop burning through brake pads leaving it smelling as though there was a fire that had taken place in the vehicle, I recently read that another company that made similar vehicles as the Mercedes Benz slk model was having similar problemns

* Brake system has failed by brakes applying randomly; research indicates due to faulty YAW sensor and Lateral Movement sensor per mechanic who retrieved the codes. Per Mercedes Benz, these sensors are no longer available and they're no longer making them. There are no aftermarket parts available. * Brakes have applied randomly at various speeds and causes a loss of control of the vehicle. This has been happening over the last few months and poses a very deadly situation. * Independent MB Specialist Master Mechanic pulled codes and confirmed problem. He advised there are no parts available. * No lamps indicated problem was imminent.

ON THREE OCCASIONS THE BRAKES WERE APPLIED BY THE STABILITY CONTROL SYSTEM WITHOUT DRIVER INTERVENTION. IN THE MOST RECENT OCCURRENCE THIS ACTION PLACED THE DRIVER AND OTHER MOTORIST IN THE VICINITY OF THE CAR IN EXTREME DANGER. TRAVELING EAST BOUND ON HIGHWAY 80 THROUGH FAIRFIELD CALIFORNIA IN THE LEFT LANE AT APPROXIMATELY 75 MPH, THE BRAKES WERE ABRUPTLY ACTIVATED BY THE STABILITY SYSTEM CAUSING THE CAR TO YAW TO THE RIGHT AND THEN SUDDENLY TO THE LEFT. FORTUNATELY THERE WAS ENOUGH DISTANCE BETWEEN OTHER MOTORIST THAT THERE WAS NOT A COLLISION. THE CAR DID HOWEVER ALMOST COLLIDE WITH THE CENTER BARRIER. THIS WAS AN EXTREMELY DANGEROUS SITUATION.

I DO NOT KNOW WHAT THIS IS INVOLVING, BUT FROM WHAT I HAVE READ IT MAY BE A SENSOR AND EVERYBODY THAT HAS HAD THIS PROBLEM COULD NOT EASILY GET A MECHANIC THAT UNDERSTOOD WHAT TO DO. THIS IS A VERY DANGEROUS ISSUE. THIS HAS HAPPENED NOW THREE TIMES AND I CANNOT DRIVE THE CAR NOW. I HAVE LOW MILEAGE ON THIS CAR. I WAS DRIVING ABOUT 55 MILES AND HOUR AND SUDDENLY MY CAR BRAKED, MADE A SCRAPING NOISE & SWERVED TO THE RIGHT. THIS LASTED 20 SECONDS. IT SCARED ME SINCE SOMEONE WAS BEHIND ME AND ABOUT RAN INTO MY REAR END, NOT TO MENTION OTHER CARS AROUND ME. MY MECHANIC CHECKED MY CAR WITH THE BENZ COMPUTER SYSTEM AND DID NOT FIND ANYTHING AND TOLD ME SOMETIMES THIS HAPPENS AND IT NEVER HAPPENS AGAIN. TONIGHT IT HAPPENED TWO MORE TIMES ON THE FREEWAY AND WHILE DRIVING OVER THE CANYON WHERE MANY CARS GO OFF THE CANYON ROAD OVER CLIFFS. IT LASTED A GOOD 20 SECONDS DOING THE SAME THING AND IT WAS A CROWDED FREEWAY. THIS TIME I FOUND THAT MY BAS/ESP LIGHT CAME ON. AFTER RESEARCHING THIS ISSUE I FIND THAT YOUR COMPANY DROPPED THE RECALL ISSUE ON THIS CAR WHEN THIS IS AN EXTREMELY SERIOUS PROBLEM. MOST MECHANICS CANNOT FIX THIS PROBLEM AND I SEE THAT MERCEDES KNOWS ABOUT THIS & THAT THERE WAS A POTENTIAL RECALL ISSUE. DOES SOMEBODY NEED TO DIE TO FIX THIS WITH A RECALL? VERY FRIGHTENING THAT THIS ISSUE HAS NOT BEEN TAKEN CARE. AS SAID MANY MECHANICS DON'T KNOW WHAT IT IS AND CARS STILL HAVE THE SAME SERIOUS PROBLEM. HOW CAN THIS ISSUE BE TAKEN LIGHTLY??

VEHICLE APPLIED BRAKES ON IT'S OWN AT HIGHWAY SPEED AND NO DRIVER APPLICATION. THE BAS/ESP ALARM LIGHTS CAME ON AND THE VEHICLE SEEMED TO BE OK UNTIL IT WAS TURNED OFF. THE ALARM CLEARED WHEN RESTARTED BUT THE VEHICLE APPLIED BRAKES AGAIN ON IT'S OWN AND THE INDICATORS CAME BACK ON. THE REPAIR SHOP COULD NOT GET A CODE BECAUSE IT WAS NOT ON WHEN THEY CHECKED IT. THIS HAS HAPPENED AT LEAST 10-12 TIMES BUT ONLY DURING HOURS WHEN THE BUSINESS IS CLOSED. I LET MY LOCAL MECHANIC DRIVE IT FOR A WEEK AND IT NEVER HAPPENED WITH HIM. THIS IS VERY SPORADIC BUT DANGEROUS SITUATION. I'VE SEEN NUMEROUS ENTRIES ON SLK FORUMS WITH OWNERS HAVING THE SAME PROBLEM WITH THIS VEHICLE.

MERCEDES SHOULD FIX THESE CONTINUAL PROBLEMS THAT CONTINUE TO COST US BIG BUCKS TO FIX $600.00 EACH TIME BECOMES TO MUCH, LAST MERCEDES FOR ME OR FRIENDS AND FAMILY. MERCEDES STAND BEHIND YOUR PRODUCT IT'S A SHAME WE HAVE TO CONTINUE TO FIGHT WITH A BIG COMPANY LIKE MERCEDES, I HOPE SOMEONE DOES SOMETHING TO CORRECT THESE ON GOING PROBLEMS WITH THESE EXPENSIVE CARS.

MY BRAKE LIGHTS ARE DEFECTIVE; THEY HAVE BEEN REPAIRED SEVERAL TIMES BUT AFTER A FEW MONTHS, THEY STOP WORKING. I HAVE THIS CAR SINCE 2006 AND HAVE BEEN TOLD THIS WAS A RECALL ISSUE. BUT WHEN I WENT TO AUTOBAHN MOTORS IN BELMONT, CA, THEY REFUSED TO REPAIR THEM. I WAS TOLD BY ANOTHER MB DEALER THAT THE RECALL WAS FINISHED AND BY ANOTHER THAT THEY HAD BEEN REPAIRED AT SOME POINT (?); I UNDERSTAND THAT IT IS NOT THE BRAKE LIGHTS THEMSELVES BUT SOME MECHANISM THAT WAS FAULTY AND THAT HAS TO BE REPLACED. I CANNOT AFFORD TO HAVE THEM REPAIRED EVERY 3 OR 4 MONTHS AND FEEL MB SHOULD DO IT SINCE IT WAS A RECALL AND THE LIGHTING MECHANISM SHOULD STAY FIXED.
