1. IT WAS ON I-15 HIGHWAY NORTH BOUND AROUND 9:44 AM, 2/1/2018. 2. THIS VEHICLE SUDDENLY LOST POWER AND APPLIED BRAKE BY ITSELF ! THAT RESULTED IN DRASTICALLY SPEED DROP IN A VERY SHORT TIME. I TRIED TO GAS IT AND I CAN FEEL ENGINE IS STILL RUNNING, BUT SPEED WAS KEPT DROPPING. 3. I ALMOST HIT BY THE CARS BEHIND ME DURING THE TIME I TRIED TO PULL OVER TO ROAD SIDE. 4. WHEN I FULLY STOPPED ON I-15 ROAD SIDE, ENGINE IS STILL RESPONSIVE (RPM CAN GO UP), BUT THE CAR CAN'T MOVE FORWARD. I TRIED TO RELEASE BRAKE WITH TRANSMISSION STILL IN "D", IT'S FUNNY THAT THIS VEHICLE STARTED TO MOVE BACKWARD (IT WAS A UPHILL SECTION). 5. FINALLY, I TURNED OFF ENGINE AND RESTARTED IT, THE CAR WAS RESTORED IN "NORMAL" STATE. JUST LIKE NOTHING HAPPENED. HOW IRONIC IT IS ! 6. THERE ARE NO WARNING/ERROR LIGHTS ON !!! 7. THIS CAR IS ALREADY IN DEALER FOR 2 WEEKS AND THEY STILL CAN'T FIND THE ROOT CAUSE. I STRONGLY BELIEVE THAT THERE COULD BE DESIGN FLAWS. THIS TIME ME AND THOSE DRIVERS BEHIND ME WERE JUST LUCKY, THERE WAS NOT A SERIOUS ACCIDENT HAPPENED. SOMETHING NEED TO BE DONE BEFORE SOMEONE IS KILLED BY THIS ISSUE. 8. I HAVE DASH CAM VIDEO STORED ON GOOGLE DRIVE. HERE IS THE LINK: HTTPS://DRIVE.GOOGLE.COM/FILE/D/1V67T9EQW3N_I2DTW_L-G7C-EXYBWDKHF/VIEW 9. SPEED UNIT ON VIDEO IS KMH, INSTEAD OF MPH. ALSO, THE TIME ZOOM OF DASH CAM IS NOT PROPERLY SET. THE TIME SHOWN ON THIS VIDEO IS ACTUALLY 16 HOURS AHEAD OF THE LOCAL TIME. BUT IT IS NOT A BIG DEAL HERE. 10. AT 42 SEC OF THIS VIDEO, YOU CAN SEE THE SPEED IS SUDDENLY DROPPED AND CAN ALSO HEAR TIRE SQUEEZING SOUND (CAR APPLIED BRAKE BY ITSELF). 11. THIS CAR CAN'T MOVE FORWARD BY THE ENGINE AT (1'52" ~ 1'55"), (2'34" ~ 2'37") AND (2'54" ~ 2'57"). 12. WITH TRANSMISSION IS STILL IN "D" AND BRAKE RELEASED, THE CAR MOVED BACKWARD BECAUSE IT WAS ON A UPHILL SECTION (2'23" ~ 2'30").

THE VEHICLE'S HEATING, VENTILATION, AND AIR CONDITIONING SYSTEMS ('HVAC SYSTEMS') HAVE A SERIOUS DESIGN DEFECT THAT CAUSES THE HVAC SYSTEM TO (A) ACCUMULATE MOLD AND MILDEW RESIDUE OR GROWTH WITHIN THE HVAC SYSTEM; (B) EMIT A MOLDY OR MILDEWY ODOR THAT PERMEATES THE VEHICLE CABIN WHEN THE HVAC SYSTEM IS ACTIVATED; AND (C) CAUSE THE VEHICLE'S PASSENGER CABIN TO BE UNBEARABLE AND THUS UNUSABLE FOR ITS INTENDED PURPOSE. IT LACKS A WAY TO PROPERLY DISPOSE OF THE WATER LEFT IN THE SYSTEM DUE TO CONDENSATION AND THIS IN TURNS CREATES A SUITABLE ENVIRONMENT FOR THE GROWTH OF BACTERIA, FUNGUS, MOLD, AND SPORES, WHICH THEN ARE BLOWN INTO THE PASSENGER CABIN WHEN THE HVAC SYSTEM IS IN USE. THIS SEEMS TO BE A KNOWN ISSUE WITH MERCEDES-BENZ CARS WHICH HAS NOT BEEN ADDRESSED BY THE MANUFACTURER. IT MAKES IT VERY UNPLEASANT TO DRIVE THE CAR WHEN YOU NEED TO TURN ON THE A/C FOR A CAR THAT IS PRACTICALLY NEW.

I WAS IN A COLLISION IN WHICH I REAR ENDED ANOTHER SUV. THE SPEED CONTROL DID NOT ENABLE AND I HIT THE OTHER VEHICLE HARD ENOUGH TO CAUSE $20,000 WORTH OF DAMAGE TO MY CAR. I BELIEVE THE CAR BRAKING RESPONSE WAS SLOW AND THE AIRBAG SHOULD HAVE DEPLOYED IN A CRASH THAT SIGNIFICANT, BUT IT DID NOT.

DIESEL FUEL LEAKS FROM A TINY CRACK FORMING ON THE OIL FILTER HOUSING. THE FILTER HAS MANUFACTURING OR DESIGN DEFECT THAT CAUSES THE BOTTOM HOUSING OF THE FILTER TO FORM SMALL CRACKS PREMATURELY. THE MERCEDES PART NUMBER OF THIS FILTER IS A 642 090 60 52 MANUFACTURED BY MANN , MADE IN THE CZECH REPUBLIC. I HAVE SEARCHED THE INTERNET AND THIS APPEARS TO BE A SYSTEMIC PROBLEM WHERE THE FILTER FORMS CRACKS AND LEAKS DIESEL FUEL. THERE SHOULD BE A RECALL ISSUED FOR THIS IMMEDIATELY BEFORE THERE ARE ANY VEHICLE FIRES AS A RESULT OF THIS DEFECT. WHEN THE FILTER LEAKS, THE FUEL STREAMS DOWN THE CENTER OF THE ENGINE BLOCK AND THROUGH A WEEP HOLE TO THE BOTTOM OF THE VEHICLE NEAR THE EXHAUST. THIS IS IN VERY CLOSE PROXIMITY TO THE EXTREMELY HOT EXHAUST PIPING THAT COULD IGNITE THE FUEL AND CAUSE A FUEL FIRE RESULTING IN SERIOUS INJURY OR FATALITIES.
