Subject: Complaint Regarding Failure to Repair Safety Recall – Brake Booster (STOP DRIVE ORDER) Background In August 2022, I received a “STOP DRIVE ORDER” recall notice from Mercedes-Benz, informing me that my ML350 was unsafe to drive due to a defective brake booster. Despite repeated attempts over nearly three years, the recall repair has not been completed. Attempts to Obtain Recall Repair Initial Attempts: Contacted Fletcher Jones Mercedes-Benz (Las Vegas) twice; they refused to schedule service citing workload. Henderson Dealership: Scheduled inspection with Mercedes-Benz of Henderson. Technician inspected my ML350 at my home, confirmed the brake booster issue, and arranged for towing. Improper Repair Demands: After holding my vehicle two weeks, Henderson dealership issued an $8,200 estimate for unrelated repairs (tires, control arms, starter). I refused, as these were unnecessary and unrelated to the recall. The service manager demanded I remove the vehicle from the lot immediately or he would have it towed to impound. Recall Parts Unavailable When I contacted Mercedes-Benz USA, I was told parts for the brake booster recall were not available, contradicting the dealership’s prior statements. My vehicle was returned unrepaired. Vehicle Mishandling •Tow company returned the vehicle at the wrong time, left it on the street with a window down, and failed to return the key. •Despite repeated requests, the key has never been returned. •The ML350 sat exposed for months, registration expired, and I had to hire another tow company to move it to my driveway. Lack of Resolution •Vehicle has been unusable for nearly 3 years. •My written correspondence and calls to Mercedes-Benz USA have gone unanswered or been mishandled (frequent transfers/dropped calls). •I have suffered financial costs, inconvenience, and loss of vehicle value. I respectfully request that 1.Immediate replacement of the defective brake booster at no cost. 2.Retrieval of my original vehicle key o

In mid February/early March the brakes failed while the vehicle was moving in a parking lot. After exiting the vehicle with the emergency brake on, I found a pool of brake fluid under the car. After towing it home, I had to make the decision to leave the car sitting as I did not have the financial resources to take it to an authorized mechanic as I had lost my job in January. In May learned of the recall and called the number, only to be told that I have to wait for a letter in the mail and to do nothing until I receive a letter. After roughly 2 months we received that letter, and the only instructions were to set up a service appointment, which I did at their earliest date available, which was 20 days later. As the car sat undriveable for months on end the lines clearly corroded further and further, and the battery was also damaged by sitting uncharted for that period of time. So when they received the car, they would not repair the car until the battery was replaced, which they would not cover even though they are clearly the cause of that as well. Then, four days after receiving the car, they have decided that the brake failure was caused by excessive corrosion (which was not there until the car sat for as many months as it did) and they would not cover the repair nor finish the safety recall, and as I type this, have not confirmed if they are even going to cover the tow back to my home(over an hour away) so that I can perform the brake line repairs myself. I find all of this extremely hard to believe as we purchased the car less than two years before the incident and the steel lines were inspected before we picked it up. I understand corrosion can cause failure like this in extreme situations over long periods of time, but I do not believe that it was not caused by their neglect. I am desperate for help at this moment.

LOSS OF ALL BRAKES DIAGNOSE CORRODED/RUSTED BRAKE PIPE AT CENTER LEFT OF VEHICLE

MY REAR BRAKE LINES HAVE CORRODED TO THE POINT THAT I LOST MY BRAKES. THE FLUID HAS LEAKED OUT. THE CAR IS NOT RUSTING OR SHOWING SIGNS OF RUST OR CORROSION. ONLY THE ACTUAL BRAKE LINES HAVE RUSTED. IT APPEARS TO BE A DEFECT IN MANUFACTURING. THE LINES SHOULD HAVE HAD A PROTECTIVE COATING OR BEEN COVERED IN THE EXPOSED AREA TO PREVENT EXCESSIVE CORROSION TO THE POINT THE BRAKE LINES RUSTED THRU AND THE VEHICLE LOST IT'S BRAKING ABILITY. THIS HAPPENED WHILE WAS IN STOP AND GO TRAFFIC SO LUCKILY NOBODY GOT HURT BUT IF I WAS AT A HIGH RATE OF SPEED I WOULD HAVE LOST MY BRAKING ABILITY AND IT COULD HAVE BEEN MUCH WORSE.

WHEEL SPEED SENSOR (L/F) FAILED ON HIGHWAY AT 50MPH. ALL BRAKES LOCKED UP AND CAR SKIDDED TO A HALT! LUCKILY NO TRAFFIC OR SOMEONE COULD HAVE BEEN KILLED! CAR HAD TO BE TOWED TO A LOCAL MB DEALER. MERCEDES IS AWARE OF THIS ISSUE ... THEY HAVE UPDATED THESE SENSORS BUT ARE NOT REPLACING THEM UNDER WARRANTY (AND OF COURSE THEY ARE GETTING ABOUT $450 PER SENSOR)! MAJOR SAFETY ISSUE! MERCEDES SHOULD RECALL AND REPLACE THESE SENSORS!
