  PUTTING THIS CAR INTO PARK WILL NORMALLY AUTOMATICALLY SET THE PARKING BRAKE. EARLIER THAT DAY, IT DID NOT SET THE BRAKE. I ASSUMED I MUST HAVE HIT SOME BUTTON OR SOMETHING ON MY DASH TO CAUSE THAT. BUT THEN ON THE FREEWAY, THE CAR (FOR WANT OF A BETTER TERM) STARTED WIGGLING AND I FOUND IT HARD TO CONTROL IT WITH THE STEERING WHEEL. IT STOPPED DOING THAT FOR A FEW SECONDS, AND THEN IMMEDIATELY HAPPENED AGAIN. AS I STARTED TO CHANGE LANES TO MOVE TOWARD THE RIGHT SIDE OF THE FREEWAY, IT DID IT A THIRD TIME BUT IT WAS WORSE AND I HAD NO CONTROL AT ALL. IT WAS MOVING TOWARD THE RIGHT BUT OUT OF CONTROL AND WENT UP ON AN EMBANKMENT AND THEN BACK DOWN AGAIN. WHEN I LOOKED INTO IT, I REALIZED IT…

  I BOUGHT A NEW 2016 MODEL (FEB. 2016), AROUND NOV 2016, THE ROTORS STARTED MAKING SQUEAKING NOISE WHEN BACKING UP, SO I TOOK TO DEALER TO DIAGNOSE. AT FIRST, THEY COULDN'T FIND THE ISSUE BUT AFTER READING ON THE MERC FORUM, I TOOK THE CAR BACK TO DEALER (JAN. 2017), ASKED TO CHECK THE ROTORS (NOT JUST THE BREAKS), FOUND THE ISSUE AND I PAID FOR THIS REPAIR. FAST FORWARD, JAN 2018, BROUGHT THE CAR BACK BECAUSE THE SAME SQUEAKING SOUND CAME BACK. I CALLED MERC CUSTOMER SERVICE, S/W "IRENE", AND SHE SAID THEY ARE AWARE OF THE ISSUE AND SHE WILL WORK WITH DEALER TO SEE IF THEY CAN FIX W/O FEE. SO LONG STORY SHORT, NEITHER THE DEALER NOR MERC ARE WILLING TO ADMIT THAT THIS IS A KNOWN ISSUE AND…

  I GOT MY BRAND NEW MERCEDES BENZ GLC 300 TWO WEEKS AGO. AFTER DRIVING FOR 6 DAYS & LESS THAN 300 MILES IN TOTAL THE SUV STOPPED RESPONDING ABRUPTLY IN THE MIDDLE OF HIGHWAY CRUISING AT A SPEED OF 70 MPH WITH A TRANSMISSION MALFUNCTION ERROR FLASHING. WITH NO POWER IN THE CAR, I WAS LUCKY ENOUGH TO PULL IT FROM THE LEFT MOST LANE TO THE RIGHT CURB BUT IT WAS EXTREMELY SCARY TO EXPERIENCE THE SITUATION OF AN IRRESPONSIVE CAR IN THE MIDDLE OF HIGHWAY WHILE THE CAR IS MOVING. ALL THE LIGHTS ON THE DIAL WERE LIT UP WITH A TRANSMISSION MALFUNCTION ERROR IN RED. TRIED TO SHUT OFF THE CAR USING THE ON/OFF PUSH BUTTON BUT IT DID NOT RESPOND. AFTER OPENING & CLOSING THE DRIVER SIDE DOOR, TRIED TO…

• 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…
