Good Afternoon, the status of my vehicle is simply UNKNOWN. I purchased my vehicle on the 26th last year of January. That same day I drove it back home my car was jerking. So I went back the following day to see if I could get into another vehicle because this one was malfunctioning they didn’t want to do anything for me. I tried so many different options to get out of this car I had a few scares driving this car the week of ownership. About sis times my car cut off completely during traffic and I have some recorded videos. Theirs a leakage somewhere I can fill up my gas tank to full and drive maybe two blocks away from my house and the gas meter is say that I have half a tank. Now my car is overheating, it’s not cranking it just tells me on the dashboard that 4MATIC is unavailable.

there is a known issue with the mercedes benz GLA 250 rear differential. it is defective and need to be replaced many times during the life of the vehicle. i have not had an accident that i can relate to this defect but i feel it need to be reported and investigated by your office. the cost of the repair is over $6000. you can read more about this issue in this forum [XXX] i started reporting the issue before the warranty expired, the dealer was never able to find the problem, after the warranty expires they "discovered" what the issue is, the rear differential need to be replaced. of course they deny any wrongdoing but this is a well documented manufacturing defect that should be addressed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Rear differential has failed/malfunctioned. The vehicle is available upon request. It is a road safety issue as it will stall/ hesitate when accelerating and has a jerking effect.

Car randomly shifts to neutral, displays message : "reverse not available" or "transmission malfunction". Car rapidly slows down causing cars behind to make avoidance maneuvers. Scanned fault codes: P079200 (transmission rpm sensor 1 malfunction) P274600 (transmission rpm sensor 2 malfunction)

The car had only 71,000 miles on it when it it had a crank no start situation that immobilized it and had to be towed. After diagnostics at two repair shops, it was determined that the exhaust camshaft was the cause. This model year car has a recall (Mercedes campaign 2015100009 and NHTSA campaign 15V662000) for the camshaft but not for the car's VIN. This failure should not occur in a car with this mileage. Had it suddenly stalled while driving, it could have resulted in a potential accident.

Upon start, got a "reverse not possible" warning. Tried to drive home, but shifting was very erratic and car slowed dramatically between shifts. On several occasions, cars behind me had to swerve to avoid me. And, if I would have had to reverse out of danger, I would have been in serious trouble. After too many close calls, I stopped to arrange a tow. When I returned to the car to move it, the problem went away. I am afraid to put my family in this car.

THE VEHICLE SLIPS INTO NEUTRAL AND SAYS 4 MATIC NOT AVAILABLE. I HAVE TO COAST TO A STOP AND THEN SHUTOFF THE VEHICLE, TURN IT OFF AND THEN RESTART IT. ALSO THE FORWARD COLLISION WARNING ALERTS WHEN I PASS UNDERNEATH A LARGE METAL FREEWAY SIGNAGE.

IT APPEARS THAT WHEN THE TURBOCHARGER IS ENGAGED, COOLANT LEAVING THE TURBOCHARGER IS SPRAYING FROM WHERE A PRESUMABLY NOW MISSING CLAMP WOULD OTHERWISE FORM A TIGHT FIT AROUND THE TUBING, WHICH IS NORMALLY HOUSED BENEATH HEAT SHIELDING. THE HEAT SHIELDING HAS BEEN DISPLACED BY THE HIGH PRESSURE PRODUCED BY THE HOT LIQUID. THE LIQUID IS SO HOT LEAVING THE TURBOCHARGER THAT AS IT SPRAYS OUT ONTO THE SURROUNDING AREAS IT HAS MELTED THE AIR INTAKE SYSTEM.

I HAD TWO MVA ACCIDENTS (FEBRUARY 1 AND MARCH 16, 2016) IN THIS VEHICLE WITHIN~ 3 MONTHS OF OWNERSHIP. THE ACCIDENTS OCCURRED WHEN I SLOWED DOWN THIS VEHICLE UNDER 10-15MPH. UPON PURCHASE, I NOTICED UNLIKE OTHER CARS I HAVE OWNED, AT A STOP THIS MBGLA 250 VEHICLE ENGINE WOULD CUT OFF COMPLETELY AND START BACK WHEN THE GAS PEDAL WAS PRESSED. I WAS TOLD BY THE DEALERSHIP THIS WAS NORMAL. HOWEVER, I NOTICED WHEN I RECEIVED THE CAR BACK FROM PARK PLACE BODYWERKS IN MARCH, 2016, (AFTER ~ 5 WEEK REPAIR PERIOD FROM THE FIRST ACCIDENT THAT OCCURRED IN FEBRUARY 2016) THE ENGINE GEARS WOULD JUMP FROM 1ST TO 4TH AFTER SLOWING DOWN ON THE BRAKE FOLLOWED BY STEPPING ON THE GAS PEDAL, IT FELT LIKE THE CAR WAS JUMPING BETWEEN GEARS, I WAS NOT ABLE TO CONTROL THIS. THE CURRENT CAR ACCIDENT HAPPENED ON MARCH 16, 2016, WITHIN 1 WEEK POST REPAIR FROM PARK PLACE BODYWERKS, AFTER I STOPPED AT A STOPPED LIGHT I HIT THE LIGHT POLE, RESULTING IN FRONT END DAMAGE AND NO AIRBAG DEPLOYMENT. DURING THIS CONTINUOUS ADDITIONAL 3 MONTH REPAIR PERIOD, I WAS NOTIFIED IN MAY, 2016 BY MY GEICO ADJUSTER THAT THE TRANSMISSION HAD THE WRONG FLUID IN IT AND THE CLAIM WOULD BE ESCALATED. IN THE DAYS THAT FOLLOW, I WAS CONTACTED BY A PARK PLACE BODYWERKS AGENT AND ASKED "DID YOU CHANGE THE FLUIDS IN THE TRANSMISSION.." I WAS EXTREMELY OFFENDED AND INFORMED HIM "I DIDN'T KNOW HOW TO OPEN THE HOOD..." AS OF TODAY, 6/13/16, GEICO HAS PAID PARK PLACE BODYWERKS ON BEHALF OF MY POLICY $28,831.30 FOR A VEHICLE I HAVE ONLY OWNED SINCE NOVEMBER 2015, DRIVEN LESS THAN 2 MONTHS, BOUGHT CERTIFIED PRE-OWNED FROM PARK PLACE BODYWERKS WITH LESS THAN 8000 MILES, CONTAINED THE WRONG TRANSMISSION FLUID FROM THE DEALERSHIP, HAD TWO LOW SPEED ACCIDENTS EACH WITH NO AIR BAG DEPLOYMENT, A HOSPITALIZATION FOR THE OWNER AND NEVER HAD A DRIVING HISTORY LIKE THIS OF MULTIPLE ACCIDENTS.

TRANSMISSION VIOLENTLY ENGAGE IN REVERSE: SO FAR I HAVE ONLY EXPERIENCED THIS (TWICE) DURING COLD-STARTS. STARTED THE ENGINE, SHIFT CAR IN TO REVERSE GEAR, DISENGAGE PARKING BREAK. IN NORMAL SITUATION, THE CAR WOULD REVERSE SLOWLY WITHOUT APPLYING THROTTLE. IN THE TWO TIMES I EXPERINCED THE PROBLEM, THE CAR WOULD STILL BE IDLE, EVEN AFTER GENTLY APPLYING THROTTLE. AFTER ABOUT 5 SECONDS OR SO, THE CAR WOULD VIOLENTLY JERK AND THE TRANSMISSION FINALLY ENGAGED IN REVERSE. THE LOCAL MB SERVICE CENTER WAS NOT ABLE TO DIAGNOSE THE ISSUE. SOME GLA OWNERS ALSO EXPERINCED THE SAME ISSUE, WHICH CAN BE FOUND IN THIS DISCUSSION: HTTP://WWW.GLAOWNERS.COM/FORUM/ENGINE-TECHNICAL-DISCUSSION/8297-TRANSMISSION-WOES.HTML HERE IS THE VIDEO THAT ILLUSTRATES MY EXPERIENCE, FROM ANOTHER GLA OWNER: HTTPS://YOUTU.BE/GLN7KPGXYB4
