The contact owns a 2006 Mercedes-Benz ML350. The contact received notification of NHTSA Campaign Number: 22V315000 (Service Brakes, Hydraulic) however, the recall repair was not performed by the dealer. The contact stated that while driving at an undisclosed speed, the vehicle intermittently experienced phantom braking with the ABS warning light illuminated. Additionally, the brake pedal went to the floorboard while depressed and made an abnormal sound; however, the brakes failed to stop the vehicle immediately. The vehicle was taken to an independent mechanic who diagnosed that the ABS sensor was faulty. The vehicle was then towed to the dealer, where it was diagnosed that the ABS sensor needed to be reset. The dealer reset the ABS sensor and informed the contact that the brake system housing was corroded and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 151,831.

Hello, There is a safety recall from the manufacturer and they have advised not to drive the vehicle. The vehicle does take a little more press on the breaks for it to function so we are assuming that we are affected by this recall. I have writen emails and called the Mercedez hotline on June 1st 2022 and they assured me over the phone that the dealership will be able to help. When i called the dealerships in St Louis, namely Plaza motors and St Louis Mercedez they declined to inspect the vehicle and advised that i can keep driving untill they inspect the vehicle. The recall from mercedez clearly states that the vehicle should not be driven. When i told them about it they changed the story and told me they dont know when they can do the inspection. Upon calling Mercedes back, they told me that they are sorry about the misinformation ad that I can rent a vehicle for reembursement but when asked about the process of getting the money back, they could not provide an answer. We did not feel comfortable renting a vehicle before knowing the process in detail so we called Mercedes back and the next person told me that the rentals will not be reimbursed. We are really in a tough situation as the car is not safe to drive per the recall and neither Mercedes or the local dealers are willing to help even after a month of the recall notice. We are hoping that either they can inspect the vehicle, give us a loaner vehicle or reimburse us for a rental vehicle. We have a small family with a 3 year old and want to make sure that we are all safe. Thank you

Since my significant others and I purchased this 2006 Mercedes Benz SUV - ML-350, over three months ago, we were wondering why the "Engine check light was always on" so we purchased (4) sensors and replaced the sensors of where OBD tests pointed out for the engine, deleted the Engine Check Light several times but it will go back on after we driven it for another 50 to 100 miles away to normal highways and freeways driving to relearn the computer system and the Check Engine Light On again and again but not blinking? We called our friendly mechanics and he said it maybe faults recalled that part of the electronics or maybe the computer is giving that "engine check" light on because it has some safety components is malfunctioning, the braking is also hard and sometimes it is too soft when I push it with my right foot to stop the car and also the car is using too much gas. So, we kept postponement of bringing this car to the dealership for repairs because we cannot afford the repairs. Then today, I check to my email and I see the Recall email from NHTSA about MB - ML-350 / recall number 2022050015 / NHTSA # 22V315, since we cannot smog check it because of the "Engine Check On" it is always on we were puzzled why this light and this car cost too much to use and sometimes hard and sometimes soft to push on it's braking power? Please let us know on what to do next? Shall we call the MB-Dealerships to tow this car to their shop because we have stop using this car about over (3) months ago since we bought it ? Braking System is sometimes is too hard and sometimes too soft and using too much gas and the "Engine Check is always On " even we have replaced the (4) electronic sensors that the OBD machine pointed out but is still doing the same thing. Please advise us of what to do to resolve these operational safety of our 2006 - ML-350 Mercedes Benz, it is stored in our car garage. The rear reverse camera also stops working and it is saying braking lights are not functioning?

Crash reported

While trying to slow in to a corner, the brakes did not work, pushing harder on the brakes caused pulling and vibration. The vehicle left the road causing damage to right fender, bumper, wheel, tire and door. The vehicle has been inspected, brake pads and brakes seemed fine. This continues to happen on a rare occasion, maybe once every 30 times vehicle is driven. This is very scarry to have brake failure, so the vehicle is rarely driven now because no remedy has been offered.

MY ML350 HAS HAD A PROBLEM WITH THE PRIMARY BRAKE LIGHTS BURNING OUT. AUTOMATICALLY THE VEHICLE IS SWITCHING TO THE SUBSTITUTE BRAKE LIGHTS. THIS IS THE SECOND SET OF BRAKE LIGHTS ON THE VEHICLE IN LESS THAN 1-MONTH. I JUST REPLACED THEM 2-DAYS AGO WITH A NEW SET OF SYLVANIA BULBS PURCHASED FROM ADVANCED AUTO AS PER THE VEHICLE MAKE, MODEL AND YEAR. I AM CONCERNED THAT THE PROBLEM COULD ORIGINATE FROM A POSSIBLE SHORT IN THE ELECTRICAL SYSTEM AND/OR POOR GROUNDING. *TR
