TL* THE CONTACT OWNS A 2014 MERCEDES CLA250. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 5 MPH, THE VEHICLE HESITATED TO ACCELERATE. THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 11,000.
DRIVING VEHICLE HOME ON I-95 SOUTHBOUND AT NIGHT. THE "ECO" DRIVE BLANKS OUT, A MESSAGE "RESCUE" APPEARS, THE SPEED DECREASES UNTIL STOPS, EVEN THOUGH THE MOTOR IS RUNNING. IF YOU TURN THE ENGINE OFF, WAIT A MINUTE AND THEN RE-START, YOU CAN DRIVE IT AGAIN. IT HAPPENED EIGHT TIMES TO ME BETWEEN FORT LAUDERDALE AND MIAMI. *TR
PULLING OFF FROM A COLD START, THE CAR SLAMS INTO 2ND GEAR. THIS HAS HAPPENED 4 TIMES, EACH TIME FROM A COLD START. A LOUD BANG IS HEARD INSIDE THE ENGINE. THIS SEEMS VERY DAMAGING TO THE CAR. I TOOK IT TOO THE DEALER THE 2ND TIME IT HAPPENED AND THEY WERE UNABLE TO REPLICATE. *TR
DRIVING ON INTERSTATE AT 70-75 MPH ENGINE LOST POWER WITHOUT WARNING AND SPEED REDUCED TO 30 MPH WITH NO RESPONSE FROM GAS PEDAL. A SEMI RAN UP BEHIND ME AND SWERVED TO THE FIRE LANE. THIS IS THE THIRD INCIDENT IN ONE MONTH. THE OTHER TWO WERE AT 45 MPH. EACH TIME I WAS ABLE TO PULL OVER AND STOP THE CAR. ONCE IT IS STARTED IT RUNS AT FULL POWER, UNTIL IT DECIDES TO STALL AGAIN. I HAD THE CAR TOWED TO DEALERSHIP AND WILL NOT DRIVE AGAIN. I COULD HAVE EASILY BEEN IN A SERIOUS ACCIDENT. I AM IN DISCUSSION WITH GM AT DEALERSHIP TO WORK SOMETHING OUT. I WILL BE UNABLE TO SELL THIS CAR LATER IN MY OPINION BASED UPON THE COMMONALITY OF THE PROBLEM, YET THE DEALER ACTED LIKE THEY HAD NEVER HEARD OF IT. I SHOULD HAVE GOOGLED IT FIRST AND THEN REMINDED THEM OF THE ISSUE. THIS IS UNACCEPTABLE. *TR
THIS IS ACTUALLY THE THIRD TIME THAT THIS HAPPENS TO MY CAR BUT THIS TIME I WAS DRIVING ON THE FREEWAY AND IT WAS A PRETTY SCARY EXPERIENCE. I WAS DRIVING ON THE FREEWAY AT ABOUT 60 MPH. ALL OF THE SUDDEN, MY CAR LOST SPEED AND POWER. A WARNING MESSAGE SHOWED ON MY DASHBOARD READING "PRE-SAFE FUNCTIONS LIMITED SEE OPERATOR'S MANUAL" AT THIS POINT MY CAR WAS STILL RUNNING BUT AT A LOW SPEED AND I COULD NOT ACCELERATE. I WAS DRIVING ON THE FAST LANE OF THE FREEWAY. I PUT MY EMERGENCY LIGHTS ON AND LIKELY THE CAR BEHIND ME NOTICED THAT I WAS HAVING ISSUES WITH MY CAR. I TURNED OFF THE CAR, WAITED ABOUT A MINUTE AND TURNED THE CAR BACK ON AS I HAD DONE THIS THE OTHER TWO TIMES THAT THIS HAD HAPPENED. ONCE I TURNED THE CAR BACK ON, I WAS ABLE TO DRIVE HOME. HOWEVER THIS WAS A VERY SCARY EXPERIENCE AS THE CAR LOST SPEED AND THE CAR BEHIND ME COULD HAVE REAR ENDED ME. ANOTHER ISSUE WITH THIS CAR IS THAT THE ENGINE LIGHT HAS COME ON ABOUT 3 TIMES IN THE LAST MONTH AFTER RECEIVING A WARNING MESSAGE "INOPERATIVE". ANOTHER ISSUE "HAZARD WARNING FLASHERS MALFUNCTIONING" I HAVE LEFT A MESSAGE TO TAKE MY CAR FOR SERVICE. I AM WAITING FOR A CALL BACK. *TR
ON OCTOBER 17, 2014, VEHICLE 'PRE SAFE FUNCTIONS LIMITED, INOPERATIVE' LIGHT CAME ON THE VEHICLE WHILE DRIVING ON INTERSTATE AT APPROXIMATELY 50-60 MPH. VEHICLE WOULD NOT ACCELERATE SO COASTED TO SIDE OF INTERSTATE AND CAME TO A STOP. TRIED TO ACCELERATE FROM A STOP, CAR WOULD ONLY MOVE AT A FEW MPH AND THE TRANSMISSION FELT LIKE IT WAS STUCK IN THE HIGHEST GEAR. TURNED CAR OFF AND BACK ON. PROBLEM SEEMED TO RESET AND WAS ABLE TO DRIVE HOME. DID NOT TAKE TO DEALERSHIP FOR THIS INCIDENT DUE TO READING ABOUT OTHERS' EXPERIENCE AND THAT DEALERSHIPS ARE UNABLE TO REPLICATE. *TR
ON SEPTEMBER 10, 2014 AND SEPTEMBER 21, 2014, VEHICLE 'PRE SAFE FUNCTIONS LIMITED, INOPERATIVE' LIGHT COMES ON THE VEHICLE AND THE VEHICLE LOSES POWER. BOTH TIMES DRIVING APPROXIMATELY 50-60 MPH. FIRST TIME DRIVING ON STREET AND WAS ABLE TO COAST HOME. SECOND TIME I WAS ON MAJOR HIGHWAY....VERY DANGEROUS! UNABLE TO ACCELERATE BOTH TIMES. TOOK VEHICLE INTO LOCAL DEALERSHIP ON SEPTEMBER 11TH, THEY WERE UNABLE TO REPLICATE ISSUE AND RETURNED CAR. DID NOT DRIVE VEHICLE FOR 1 WEEK DUE TO TRAVEL, RETURNED AND WITHIN 2 DAYS OF DRIVING THE CAR, ERROR MESSAGE RETURNED AND I WAS UNABLE TO ACCELERATE CAR. TO GET THE CAR TO FUNCTION, MUST TURN THE VEHICLE OFF AND BACK ON AND THEN IT DRIVE-ABLE. VEHICLE IS CURRENTLY BACK AT THE DEALERSHIP FOR REPAIR. THIS ISSUE ACTUALLY OCCURRED SEVERAL WEEKS PRIOR BUT I DID NOT REPORT TO THE DEALERSHIP BECAUSE THE LIGHT CAME ON AND QUICKLY WENT BACK OFF. ALSO EXPERIENCED SLOW ACCELERATION ISSUES WHEN MOVING FROM A COMPLETE STOP. *TR
AS I WAS DRIVING ON THE HIGHWAY AROUND 65 MILES PER HOUR, THE VEHICLE'S CHECK ENGINE CAME UP AND SAID " INOPERATIVE, PRE SAFE INACTIVE" I FREAKED OUT. I WAS AT HIGHWAYS SPEEDS AND IT WAS INOPERATIVE. I NOTICED THAT THE POWER STEERING WAS AFFECTED AND THE VEHICLE WAS UNRESPONSIVE WHEN I ACCELERATED. THE ABS SYSTEM WAS DISABLED, I WAS SCARED EVEN TO BRAKE BECAUSE I KNOW THAT WHEN THE ABS SYSTEM IS DISABLED THE BRAKES CAN LOCK UP AND CAUSE AN ACCIDENT, INJURIES AND EVEN DEATH. I HAVE NOTICED THAT MANY CLA250 OWNERS HAVE THE SAME PROBLEM. *TR
I WAS DRIVING ON A MAIN ROAD WHEN SUDDENLY THE CAR SHUTS OFF COMPLETELY. I COULD NOT GET IT TO START, NOR PUT IT ON NEUTRAL GEAR, TO AT LEAST PUSH IT AWAY. A MESSAGE IN RED POPS UP ON THE SCREEN THAT SAYS "SERVICE REQUIRED, DO NOT SHIFT GEARS, VISIT DEALER". I COULD NOT PUSH THE CAR AT ALL, BECAUSE THE GEAR SHIFTED AUTOMATICALLY TO PARKING AND IT WON'T MOVE TO NEUTRAL. I WAS STUCK ON THE MAIN ROAD FOR 15 MINUTES. I WAS LUCKY NOT TO GET HIT OR RUN OVER BY THE INCOMING TRAFFIC. I CAUSED A PANIC ON THE STREET BECAUSE I WAS BLOCKING IT. FORTUNATELY, A POLICE CAR SHOWED UP, AND THE OFFICER HELPED ME BY DIVERTING THE TRAFFIC AWAY FROM ME. I HAD THE CAR CHECKED TWO MONTHS PRIOR TO THIS INCIDENT AT THE DEALER, AND THEY TOLD ME THAT THERE IS NOTHING WRONG WITH THE CAR, AND THAT THEY HAVE UPDATED ITS SOFTWARE TO THE LATEST VERSION. I HAD THE CAR TOWED BACK TO MERCEDES-BENZ NOW, AND WILL WAIT THE RESULTS. *TR
TRAVELING APPROXIMATELY 15MPH AND SLOWLY ACCELERATING, VEHICLE BECAME COMPLETELY UNRESPONSIVE TO THROTTLE INPUT, AND ENGINE REMAINED AT IDLE SPEED. DISPLAYED SHOWED THE MESSAGES "PRE-SAFE INOPERABLE" AND "SEE OWNER'S MANUAL." AFTER THE ENGINE WAS SHUT OFF AND RESTARTED, THE CAR DROVE NORMALLY. IT WAS TAKEN INTO THE DEALER FOR INSPECTION AND REPAIR, AND WAS RETURNED TO ME AFTER THE SERVICE ADVISER ADVISED ME THAT THEY COULD "FIND NO CODES." THE VERY SAME ERROR OCCURRED A FEW DAYS LATER. THIS TIME THE SERVICE ADVISER SAID THAT ERROR CODES WERE FOUND, THAT THERE WAS A "CONFLICT IN THE PROGRAMMING", THAT ALL OF THE HARDWARE CHECKED OUT, AND THAT "REPROGRAMMING THE MODULE" WILL FIX IT. 36 HOURS LATER IT OCCURRED AGAIN. THIS TIME THE ADVISER SAID THAT A MERCEDES BENZ SERVICE DATABASE INDICATED THAT THE PROBLEM WAS WITH A WIRING HARNESS IN THE THROTTLE, AND THAT REPLACING THAT HARNESS WILL FIX THE PROBLEM. *TR
DRIVER LEFT SIDE MIRROR DOES NOT GIVE ADEQUATE VIEW OF TRAFFIC ON HIGHWAY TO LEFT OF DRIVER. IT CANNOT BE ADJUSTED FAR ENOUGH SO THERE IS AN EXCESSIVE BLIND SPOT. I DARE NOT CHANGE LANES TO LEFT WITHOUT TURNING MY HEAD EXCESSIVELY, AND THIS PRESENTS A RISK WHEN DRIVING AT HIGHWAY SPEED. THIS IS NOT THE CASE WITH THE RIGHT SIDE MIRROR. ALSO, WE HAVE A 2012 MERCEDES C250 AND THIS DOES NOT HAVE THE PROBLEM. *TR
I WAS TURNING ON TO A BUSY 3-LANE ROAD DURING RUSH HOUR, SPEED LIMIT 45 MPH WITH MOST CARS TRAVELING AT 50 MPH. WHILE ACCELERATING AFTER MAKING A RIGHT TURN ON TO THE STREET, MY CAR SUDDENLY RECEIVED A "PRE-SAFE" ERROR TO THE DASHBOARD AND STOPPED ACCELERATING WHILE HEADING APPROXIMATELY 40 MPH. AS I HAD JUST SHORTLY MADE THE TURN, I HAD NOT CAUGHT UP TO THE SPEED OF TRAFFIC AND THE SUDDEN STALL CAUSED THE CAR TO DECELERATE. THE ABRUPTNESS OF THE MALFUNCTION NEARLY CAUSED ME TO GET INTO TWO REAR END ACCIDENTS WHILE JUST USING MOMENTUM TO REACH A SPOT ON THE ROAD WHEREBY TO SAFELY STOP THE CAR. THE CAR WOULD NOT ACCELERATE DESPITE RESTARTING AND REQUIRED A TOW. THE CAR IS 3 WEEKS OLD AND WAS BOUGHT BRAND NEW. *TR
WHILE DRIVING DOWN THE ROAD THE CAR SUDDENLY WENT INTO PARK. THE PARK BUTTON WAS NOT TOUCHED, NOTHING WAS NEAR IT, AND IT COULD NOT HAVE BEEN ACCIDENTALLY PRESSED. THE CAR SLAMMED INTO PARK ON IT'S OWN. *TR
WHILE DRIVING THE VEHICLE LOSES POWER AND BARELY HAS ANY ACCELERATIONS. THE WARNING SIGN SAID INOP SEE OWNERS MANUAL. I HAD TO PULL OVER, RESTART CAR THEN IT WAS BACK TO NORMAL. THIS HAS HAPPENED TWICE AT THE EXACT SAME ROAD. I WAS AT A STOP LIGHT, MADE A LEFT TURN, DROVE ABOUT HALF A MILE THEN THIS STARTED. THIS IS VERY DANGEROUS! *TR
WHILE DRIVING UNDER NORMAL CONDITIONS THE CAR STALLED WITH NO WARNING. A NUMBER OF DASHBOARD WARNING LIGHTS CAME ON INCLUDING THE PARKING BRAKE, TRACTION CONTROL, ABS, ENGINE, TIRES, AIRBAG, ETC... THERE WAS A RED MESSAGE IN THE INFORMATION DISPLAY THAT READ "SERVICE REQUIRED. DO NOT SHIFT GEARS. VISIT DEALER.", THAT ALTERNATED WITH A YELLOW MESSAGE THAT READ "TRACTION CONTROL INOPERATIVE. SEE OPERATOR'S MANUAL." I WAS ABLE TO COAST CLOSE TO THE CURB TO MOVE OUT OF THE TRAFFIC LANE BUT THE CAR WOULD NOT TURN OVER. A FLAT BED WAS CALLED TO TAKE IT TO THE MERCEDES DEALERSHIP. *TR
I JUST PICKED UP MY CAR FROM MERCEDES SERVICE TODAY, 7/10/2014 FOR THE ISSUE DESCRIBED BELOW. IT HAD BEEN IN SERVICE SINCE 7/1/2014. THE SERVICE REPRESENTATIVE SAID THAT IT WAS AN ELECTRICAL ISSUE. ONE PART THEY NEEDED WAS BACK-ORDERED AND UNAVAILABLE FROM MERCEDES SO THE MECHANIC REBUILT THE CONNECTION. THAT STILL DID NOT STOP THE FAULT CODE SO IN CONSULTATION WITH MERCEDES THE SERVICE DEPARTMENT REPLACED ADDITIONAL ELECTRICAL COMPONENTS AND BELIEVED THEY RESOLVED THE ISSUE. THE EXACT SAME INCIDENT OCCURRED TODAY, APPROXIMATELY 30 MINUTES AFTER PICKING THE CAR UP. WHILE DRIVING UNDER NORMAL CONDITIONS THE CAR STALLED WITH NO WARNING. A NUMBER OF DASHBOARD WARNING LIGHTS CAME ON INCLUDING THE PARKING BRAKE, TRACTION CONTROL, ABS, ENGINE, TIRES, AIRBAG, ETC... THERE WAS A RED MESSAGE IN THE INFORMATION DISPLAY THAT READ "SERVICE REQUIRED. DO NOT SHIFT GEARS. VISIT DEALER.", THAT ALTERNATED WITH A YELLOW MESSAGE THAT READ "TRACTION CONTROL INOPERATIVE. SEE OPERATOR'S MANUAL." I WAS ABLE TO COAST CLOSE TO THE CURB TO MOVE OUT OF THE TRAFFIC LANE BUT THE CAR WOULD NOT TURN OVER. A FLAT BED WAS CALLED TO TAKE IT TO THE MERCEDES DEALERSHIP. *TR
TL* THE CONTACT OWNS A 2014 MERCEDES BENZ CLA250. WHILE MAKING A LEFT TURN AT AN UNKNOWN SPEED, THE VEHICLE STALLED IN THE MIDDLE OF AN INTERSECTION. THE INOPERABLE POWER WARNING INDICATOR ILLUMINATED DURING THE FAILURE. THE FAILURE OCCURRED SEVERAL TIMES. AFTER EACH FAILURE, THE CONTACT WAS ABLE TO RESTART THE ENGINE AND RESUME NORMAL FUNCTION. THE VEHICLE WAS TAKEN TO THE DEALER MULTIPLE TIMES, BUT THEY COULD NOT DUPLICATE THE FAILURE. THE DEALER CONCLUDED THAT NOTHING WAS WRONG WITH THE VEHICLE. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 5,800.
DRIVING ON HIGHWAY AT 70 MPH WHEN I NEARLY CAUSED A COLLISION BECAUSE I ENCROACHED ON ANOTHER CAR'S SPACE IN THE NEXT LANE TO MY LEFT. I BELIEVE THIS WAS DUE TO THE FACT THAT THE CLA250 DRIVER SIDE MIRROR DOES NOT ADEQUATELY COVER THE BLIND SPOT AND DOES NOT PROVIDE SAFE AND EFFECTIVE VIEW OF THE LEFT LANE. THE MIRROR IS ADJUSTED ALL THE WAY OUT BUT CAN ONLY SEE THE QUARTER PANEL OF THE CLA250. DURING MY NEAR-COLLISION, I DID PHYSICALLY TURN MY HEAD AND SHOULDERS TO VIEW THE TRAFFIC ON THE LEFT LANE (THREE LANE HIGHWAY). IT WAS CLEAR. AS I WAS ABOUT TO SWITCH INTO THE LANE 2 SECONDS LATER, ANOTHER CARE WAS ALREADY IN THE SPACE THAT THE CLA250 SIDE MIRROR DID NOT GIVE ME A SECOND OPPORTUNITY TO VIEW. I BELIEVE THIS IS A DEFECT IN DESIGN AND PRESENTS A HAZARDOUS CONDITION. *TR
CAR COMPLETELY SHUTOFF TONIGHT ON THE HIGHWAY AND LUCKILY I WAS ABLE TO GET PULLED OVER WITHOUT INCIDENT. I HAD NUMEROUS MESSAGES ON THE DISPLAY, INCLUDING "SERVICE REQUIRED, DO NOT SHIFT GEARS, VISIT DEALER" AND "ESP INOPERABLE, SEE OPERATOR'S MANUAL". THE CAR WOULD NOT DO ANYTHING ONCE I PULLED OVER, NOTHING HAPPENED WHEN I TURNED THE KEY, NO NOISES, NOTHING. MB ROADSIDE ASSISTANCE CAME AND TRIED TO JUMP START AND DISCONNECT THE BATTERY TO NO AVAIL. SO, OFF ON THE TOW TRUCK IT WENT. *TR
WHILE DRIVING THE VEHICLE SUDDENLY THE ACCELERATOR STARTED TO HAVE A DELAYED RESPONSE. PRESSING THE ACCELERATOR WOULD NOT DO ANYTHING FOR BETWEEN 3 TO 5 SECOND AFTER THE CAR WAS STOPPED. AFTER THE DELAY, THE CAR WOULD RESPOND AND WAS DRIVABLE, BUT AFTER EVERY SUBSEQUENT STOP, THE 3 TO 5 SECOND DELAY WOULD RETURN. THIS CONTINUED FOR THE 20 MILES THAT I DROVE TO THE DEALERSHIP TO HAVE THEM LOOK AT THE CAR AND REPAIR IT. I BELIEVE THIS UNRESPONSIVENESS OF THE ACCELERATOR TO BE A DANGEROUS CONDITION AS IT PREVENTED ME FROM BEING ABLE TO DRIVING NORMALLY AND COULD HAVE PREVENTED ME FROM MOVING MY VEHICLE IF IT WAS STOPPED AND A SITUATION REQUIRED IT TO BE MOVED QUICKLY. AT THIS TIME THIS OCCURRED THE FOLLOWING WARNING LIGHTS APPEARED ON THE DASH. THE CHECK ENGINE LIGHT CAME ON. THE ESP WARNING LIGHT CAME ON, THE ESP SYSTEM "OFF" LIGHT CAME ON, AND A MESSAGE STATING THAT "PRESAFE FUNCTIONS WERE UNAVAILABLE" APPEARED ON THE DASH BOARD COMPUTER SCREEN. THIS WAS THE SECOND TIME THIS HAPPENED TO ME. THE FIRST TIME WAS AT THE BEGINNING OF APRIL. I PULLED THE CAR OVER. RESTARTED THE CAR AND THE CONDITION FIXED ITSELF. THIS TIME, RESTARTING THE CAR DID NOT CLEAR THE CONDITION. *JS
THIS HAS HAPPENED MULTIPLE TIMES STARTING IN JAN. 2014 AND MOST RECENTLY APRIL 15, 2014: COME TO A STOP AT RED LIGHT (OR STOP SIGN) AND WHEN I STEP ON GAS TO GO WHEN LIGHT TURNS GREEN, ETC., NO POWER OR, AT MOST, CAR BARELY COASTS TO SHOULDER OF ROAD. IT DOES NOT SOUND LIKE THE ENGINE ENGAGES. I TURN THE IGNITION OFF AND THEN ON AGAIN AND THE CAR RUNS. THIS HAPPENS WHEN ECO STOP/START FUNCTION IS ON AND ALSO HAPPENS WHEN IT IS OFF. I AM AFRAID TO DRIVE THE CAR BECAUSE THIS HAPPENS WITHOUT WARNING. I COULD BE DRIVING THE CAR FOR A WEEK WITH NO PROBLEM AND THEN IT HAPPENS.
I HAVE PARTIAL VIDEO IF THIS INCIDENT. INCIDENT OCCURRED AT 991 ODOMETER MILES. AFTER DRIVING APPROX. ~300 MOSTLY CONTIGUOUS, FLAT, RURAL HIGHWAY MILES IN-BETWEEN LINCOLN, NE AND ST. LOUIS, MO (HEADING TO ATLANTA, GA) IN APPROX. 30 WEATHER ON DRY PAVEMENT, THE ENGINE STOPPED PRODUCING ENOUGH ENGINE POWER TO PROPEL THE VEHICLE AT THE 70-75 MPH THAT I WAS TRAVELING. AT APPROX. 60-65 MPH, I APPLIED ADDITIONAL PRESSURE TO THE GAS PEDAL WHICH WAS NOT EFFECTIVE. PUSHING THE GAS PEDAL TO THE FLOOR DID NOTHING EXCEPT, OCCASIONALLY, THE TRANSMISSION WOULD SWITCH QUICKLY IN-BETWEEN THE SAME TWO GEARS, WHICH REGISTERED SLIGHTLY ON THE TACHOMETER BUT DID NOTHING TO ACCELERATE THE VEHICLE OR MAINTAIN SPEED. IT ALMOST FELT AS IF THE TRACTION CONTROL WAS ACTIVATING (BUT MALFUNCTIONING) DESPITE THE GROUND BEING TOTALLY DRY. BY APPROX. 50 MPH I WAS BEING FLANKED AND TAILGATED BY TWO CLEARLY DISGRUNTLED SEMI-TRUCKS AS I TRIED TO PULL OVER TO THE RIGHT. THE VEHICLE SEEMINGLY WOULD MAINTAIN A MAX. OF 35 MPH. UPON RESTARTING THE CAR (NORMAL START), LETTING IT IDLE (NORMAL IDLE), AND THEN ATTEMPTING TO DRIVE TO A SAFER LOCATION, ITS ACCELERATION FELT RESTRICTED AT LOWER RPMS, BUT IT DID BACK UP TO HIGHWAY SPEED AND THE RESTRICTED FEELING ENDED UP BEING TEMPORARY. THE NEAREST DEALER WAS MB OF MARION, IL., APPROX. ANOTHER 200-300 MILES AWAY. ON THE WAY TO THIS DEALERSHIP, THE SAME MALFUNCTION OCCURRED AGAIN ABOUT 50-75 MILES LATER. I WENT THROUGH THE SAME PROCESS AND RESTARTED THE VEHICLE. AT THE MA
I PURCHASED A NEW NEW NEW MERCEDES CLA-250C AUTOMOBILE LATE SEPTEMBER 2013. IN MID-OCTOBER I EXPERIENCED UN-COMMANDED ACCELERATION TO ABOVE 5500 RPM. THIS CEASED JUST AS I WAS ABOUT TO APPLY BRAKING. THE CAR THEN BEHAVED NORMALLY. *TR ON CHRISTMAS NIGHT I EXPERIENCED UN-COMMANDED BRAKING WHENEVER I BACKED OFF THE ACCELERATOR PEDAL, THE FORCE OF BRAKING BEING PROPORTIONAL TO THE DEGREE OF LIFT-OFF FROM THE ACCELERATOR. I WAS ABLE TO BRING THE CAR TO A COMPLETE STOP WITHOUT TOUCHING THE BRAKE PEDAL. AT THAT POINT I GROUNDED THE CAR. ON JANUARY 7, 2014 I INFORMED MERCEDES-BENZ ABOUT THE ABOVE. I AM PREPARED TO PROVIDE FURTHER INFORMATION REGARDING THE ABOVE EVENTS AND MY CORRESPONDENCE WITH MERCEDES-BENZ USA SHOULD YOU DESIRE. *TR
TL* THE CONTACT OWNS A 2014 MERCEDES BENZ CLA250. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 40 MPH, THERE WAS A REDUCTION IN ACCELERATION POWER AS THE 'PRE-SAFE FUNCTIONS NOT OPERABLE' WARNING MESSAGE ILLUMINATED. THE VEHICLE REGAINED NORMAL OPERATION ONCE IT WAS SHUT OFF AND RESTARTED. THIS FAILURE RECURRED FOUR TIMES OVER A TWO MONTH PERIOD. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER, WHO RESET THE SOFTWARE BUT TO NO AVAIL. THE MANUFACTURER WAS NOT NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 3,500.
TL* THE CONTACT OWNS A 2014 MERCEDES-BENZ CLA250. THE CONTACT STATED THAT WHILE DRIVING 65 MPH, THE VEHICLE FAILED TO ACCELERATE. THE CONTACT STATED THAT THE PRE-SAFE FUNCTIONS LIMITED INOPERATIVE, THE ELECTRONIC STABILITY CONTROL, THE ANTI-LOCK BRAKING SYSTEM, AND THE ELECTRONIC STABILITY PROGRAM WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGE WAS 2,500. THE VIN WAS NOT AVAILABLE.
1ST- ON FEB 11TH & 12TH MY 2014 CLA WHICH WAS PURCHASED AT THE MB OF PEMBROKE PINES HAD BEEN TOWED TO THE MB OF POMPANO, FL DEALERSHIP BECAUSE OF THE EPS LIGHTS, "INOPERATIVE" WARNING MESSAGES THAT WERE COMING UP AS WELL AS THE STALLING AND DELAYED ACCELERATION, WHICH I TOOK PHOTOS OF. IT WAS TOWED TO POMPANO FORM MY JOB, MY CAR WAS KEPT AT THE DEALERSHIP FOR 4 DAYS (AS OPPOSED TO THE FEW HRS I WAS TOLD THAT IT WOULD TAKE TO FIX THE COMPUTER ISSUES). NOT ONLY WAS MY CAR IN THE SHOP FOR 3 DAYS, BUT A PART THAT HAD BEEN ORDERED,WHICH MEANS SOMETHING OBVIOUSLY WASN?T FUNCTIONING PROPERLY SO IT HAD TO BE REPLACED. 2ND - I PICKED UP MY VEHICLE ON SAT FEB 15TH FROM THE POMPANO, AFTER GETTING ONTO THE I95 AND DRIVING 2 MINS, THE SAME WARNING SIGNS CAME BACK UP. I EXITED DRIVING 15MPH AND TRYING TO KEEP THE VEHICLE STABLE. MR. MIKE RODRIGUEZ WAS INSTRUCTED TO TEST DRIVE THE VEHICLE, HOWEVER, WHEN HE DID SO THE WARNING SIGNALS WERE GONE. WHY? BECAUSE A SERVICE GUY RESTARTED THE VEHICLE AND DROVE IT INTO THE SERVICE AREA. BEING THAT THE SIGNAL WAS NO LONGER VISIBLE, THE GM SUGGESTED THAT IF THERE WAS EVER A SIGNAL SENT TO THE VEHICLE IT WOULD SHOW UP IN SOME SORT OF READING THEY WERE ABLE TO DO ON THE VEHICLE. WHEN THEY RETURNED, BOTH THE GM AND MR. RODRIGUEZ INFORMED US THAT THE VEHICLE SHOWED THEM THERE WAS NO SIGNAL THAT WAS SENT TO THE VEHICLE ALL DAY. I LITTERALLY JUST SAW IT NOT 30 MINS AGO. WE LEFT & ABOUT 2 MINS FROM MY HOME IN BOCA RATON, THE SIGNAL WAS BACK WITH VENGEANCE! AT
TODAY I WAS DRIVING IN A PARKING LOT AND APPROACHED THE LIGHT TO EXIT AND MY DASHBOARD LIT UP WITH A PRESAFE SYSTEM FAILURE, SYSTEM IS INOPERATIVE AND MY CAR SLOWED DOWN CONSIDERABLY WHEN I TRIED TO ACCELERATE. I PULLED OVER AND TURNED THE ENGINE OFF AND THEN ON AGAIN AND THE ERROR CLEARED. THIS IS VERY DANGEROUS IF IT HAPPENS ON A HIGHWAY OR WHILE DRIVING ON A CROWDED STREET. I CALLED THE DEALER TODAY AND WAS TOLD IF THE ERROR WAS NOT CURRENTLY ON THE DASH THEY COULD NOT DO ANYTHING. I EXPLAINED THAT THIS WAS UNACCEPTABLE AND THEY NEEDED TO LOOK AT THE CAR. GOD FORBID I AM ON THE HIGHWAY AND IT DISABLED. LAST WEEK MY BROTHER-IN- LAW SAW THE SAME CAR DISABLED IN THE MIDDLE LANE OF THE HIGHWAY. I HOPE MB FIXES THIS PROBLEM FAST BEFORE SOMEONE IS SERIOUSLY HURT. *TR
TL* THE CONTACT OWNS A 2014 MERCEDES-BENZ CLA250. THE CONTACT STATED WHILE DRIVING 60 MPH AN EIGHT FOOT PIECE OF MOLDING ON THE RIGHT SIDE OF THE VEHICLE CAME APART. THE CONTACT PULLED OVER AND REMOVED THE MOLDING FROM THE VEHICLE. THE CONTACT TOOK THE VEHICLE TO A DEALER. THE CONTACT DID NOT CALL THE MANUFACTURER REGADING THE DEFECT. THE FAILURE MILEAGE WAS 630.
ON SUNDAY, OCTOBER 27, AND TUESDAY, OCTOBER 29, 2013, MY VEHICLE LISTED ABOVE HAD WARNING LIGHTS COME ON THAT STATED, "PRE SAFE, FUNCTIONS LIMITED, INOPERATIVE." IN ADDITION TO THE WORDS, THE ESP AND ABS LIGHTS ILLUMINATED. I TOOK THE VEHICLE TO PENSKE MBZ IN WEST COVINA, CA, ON WEDNESDAY, OCTOBER 30. THEY REPAIRED THE VEHICLE BY DOING A SOFTWARE UPDATE. ON SATURDAY, NOVEMBER 2, 2013, THE CODES RETURNED AND I TOOK THE VEHICLE BACK TO WHERE I BOUGHT IT, ENCINO, CA, MBZ. I WAS TOLD THEY COULD NOT REPLICATE THE CODES AND THEY FOUND NO PROBLEM. THIS IS UNACCEPTABLE! THE VEHICLE IS STILL AT ENCINO MBZ AS THEY ARE TRYING TO REPLICATE THE PROBLEM. WHEN THIS MALFUNCTION OCCURS, THE VEHICLE LOSES POWER AND HAS VERY LIMITED ACCELERATION. IT HAS OCCURRED TWICE ON CITY STREETS AND TWICE ON THE FREEWAY, BOTH IN ECO AND SPORT MODE. ON THE CITY STREETS I AM ABLE TO JUST PULL TO THE CURB. ON THE FREEWAY, IT BECOMES A POSSIBLE LIFE THREATENING EMERGENCY. THERE IS ONLY VERY GRADUAL ACCELERATION, AND AT 65MPH, LIMITED ACCELERATION IS VERY DANGEROUS. THESE FOUR OCCURRENCES HAVE TAKEN PLACE IN LESS THAN A 10 DAY PERIOD AND NO LONG TERM REPAIR HAS YET BEEN ACCOMPLISHED! *TR

What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
