There are 4 owner-reported brakes complaints for the 2016 Mercedes-Benz GLE-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When driving, the vehicle suddenly slows down and then the brakes stop working. Vehicle then slows down to a complete stop. Happens randomly. This put me and other drivers at risk as cars behind me would suddenly have to slow down or stop without warning and I would have to steer out of the road to avoid a collision as the car is slowing down. At the same time, a message would appear saying "Collision Prevention Assist Plus Inoperative." I took the vehicle to a mercedes-benz dealer and they confirmed that this problem is due to a fault in the ABS system.
On September 26th, 2021 I was reversing out a parking space, the rear camera was engaged and the R indication in place. While halfway out of the parking space the vehicle accelerated hitting another vehicle. The brakes would not engage to slow or stop the vehicle, I had to slip the gear into park to have the vehicle come to a completed stop. the accident was report to the insurance company and information was exchanged due to the location. Six months prior, while my daughter was reversing off the drive, similar behavior occurred, where she did not feel comfortable driving the car and parked it onto the driveway. I do not know if there's a recall or any other additional reports. please advise of the next steps in filing a complaint or opening a case.
MASTER CYLINDER LEAKED BRAKE FLUID CAUSING BRAKE PEDAL TO BE SOFT AND HIT THE FLOOR.
SINCE THE TIME I PURCHASED THIS CAR, THE BRAKES HAVE REPEATEDLY MADE LOUD SQUEALING NOISES. MERCEDES HAS REPEATEDLY EXAMINED THE CAR AND TOLD US IT IS FINE AND NOT DANGEROUS. THEY HAVE NEVER FIXED THE NOISE. HOWEVER, MORE RECENTLY IN DECEMBER 2019, THE CAR DEVELOPED A STRONG FUEL ORDER IN BOTH THE CABIN AND OUTSIDE THE VEHICLE. WE BROUGHT IT TO A MECHANIC WHO SAID IT WAS A PROBLEM WITH THE CLAMP AND THE FUEL LINE. HE CALLED THE LOCAL MERCEDES DEALER WHO TOLD HIM TO ADJUST THE CLAMP. THAT HAS NOT FIXED THE PROBLEM. THE SMELL IS VERY STRONG, AND I AM SCARED TO DRIVE THIS VEHICLE. FROM ONLINE SEARCHES, I HAVE FOUND OTHER PEOPLE SEEM TO BE EXPERIENCING THE SAME TYPE OF PROBLEM WITH MERCEDES CARS.
