Recall 19V78700024,226 vehicles

Problem: Mercedes-Benz USA, LLC.

Risk: An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.

Power train
Motor suddenly stopped on highway. This was extremely dangerous. Vehicle transported to Mercedes Benz, they have indicated the electric drive motor has failed. This is the second drive motor in this car that has failed in only 48K miles. We have two of these cars, same year and model. The motor has also failed in the other vehicle. There is an entire Facebook group talking about failures of the drive units in these cars. PLEASE FORCE MERCEDES TO DO SOMETHING!

Electrical system
TL* THE CONTACT OWN A 2014 MERCEDES BENZ B-CLASS ELECTRIC. THE CONTACT STATED WHILE HIS WIFE WAS DRIVING 55 MPH, AN UNKNOWN YELLOW WARNING LIGHT ILLUMINATED INDICATING ASSISTANCE REQUIRED. THE DRIVER CONTINUED TO DRIVE THE VEHICLE AND SHORTLY AFTER, WHILE ATTEMPTING TO PARK ON THE SIDE OF THE ROAD, ANOTHER RED WARNING LIGHT WAS ILLUMINATED AND THE VEHICLE STALLED. THE VEHICLE WAS NOT DRIVABLE. THE VEHICLE WAS TOWED TO THE LOCAL DEALER MERCEDES-BENZ OF ALEXANDRIA (200 S PICKETT ST, ALEXANDRIA, VA 22304, (703) 341-2100) WHERE IT WAS DIAGNOSED WITH NEEDING THE DRIVETRAIN TO BE REPLACED.

Service brakes
THIS IS AN ELECTRIC VEHICLE. IN NORMAL OPERATION, WHEN THE CAR IS SLOWING, AND ALMOST AT A STOP, IT COMES OUT OF REGENERATIVE BRAKING MODE, AND ENTERS THRUST MODE, SO THAT IF THE BRAKE IS RELEASED WHEN STOPPED, THE CAR WILL BEGIN TO ROLL. IN THIS VEHICLE, SOMETIMES THE CAR EXITS REGENERATIVE BRAKING MODE AND ENTERS THRUST MODE WHEN SLOWING AT HIGH SPEED, SUCH AS WHEN EXITING A HIGHWAY RAMP. THIS IS EXTREMELY DANGEROUS, AS BRAKING IS MOMENTARILY AND UNEXPECTEDLY LOST WHEN IT IS NEEDED MOST. I TOOK THE CAR INTO THE DEALERSHIP, AND THEY WERE UNABLE TO FIND ANY ISSUES OR FAULT CODES. AS THE ISSUE IS INTERMITTENT, I AM STUCK. *TR

Power train
WHEN ATTEMPTING TO REVERSE OUT OF PARKING STALL VEHICLE WOULD NOT MOVE, ALMOST AS IF EMERGENCY BRAKE WAS BEING APPLIED EVEN THOUGH EBRAKE WAS OFF. TURNING ON AND OFF IGNITION DID NOTHING. REPLACE 12 V BATTERY DID NOTHING. WARRANTY WORK ON CONTROL UNIT PERFORMED MULTIPLE TIMES IN 2017/2018/2019 EVEN THOUGH THE SOFTWARE 'FIXED' THE ISSUE RELATED TO THE RECALL NHTSA CAMPAIGN ID: 15V655000 IN 2015. DEALER STATES MUST REPLACE ENTIRE POWER TRAIN AT A COST OF $11,500. VEHICLE HAS 72K MILES AND LOAN BALANCE IS OVER $12K. THE POWER TRAIN PROVIDED BY TESLA WAS REPLACED IN TESLA'S OWN VEHICLES AS WELL AS IN TOYOTA RAV4 MODELS FROM THE SAME YEAR.

VEHICLE BATTERY WARNING LIGHT CAME ON INSTRUCTING TO STOP DRIVING VEHICLE IMMEDIATELY. LIKE SO MANY OTHER OWNERS WHO HAVE FILED COMPLAINTS, MERCEDES DEALER-MECHANIC SAID THAT COOLANT HAD GOTTEN INTO BATTERY AND DRIVE UNIT NEEDS TO BE REPLACED. ESTIMATED COST $12,000 - RENDERING CAR TOTALLED. INDEPENDENT EV SPECIALIST HAS PRESSURE TESTED COOLING SYSTEM AND FINDS NO LEAKS. FORTUNATELY, I WAS IN A SAFE PLACE AT THE TIME I NEEDED TO STOP THE CAR. IF I HAD BEEN OUT ON THE FREEWAY DURING HEAVY TRAFFIC OR AT NIGHT, THIS WOULD HAVE BEEN UNSAFE. IF THERE ARE PROBLEMS WITH THE COOLANT AND DRIVE UNIT, IT LEADS ME TO BELIEVE THAT PROBLEM COULD LEAD TO FIRE, IF NOT POTENTIAL CRASH IF DRIVER LOSES POWER…

Pedestrian alert soundsClosedLed to recall 22V063000
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review…

Desiccated Air Bag Inflator RuptureOpen
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled…
