2014 Mercedes-Benz CLA-Class Complaint Log

PRE SAFE FUNCTIONS LIMITED LIGHT AND INOPERATIVE TRACTION CONTROL LIGHT COMES ON CAR IMMEDIATELY LOSES 50 PERCENT POWER AND WILL NOT ACCELARATE. 15 TIMES IN A 1YR PERIOD. DEALER DOESN'T SEE A PROBLEM..TODAY FOR THE 5TH TIME I WAS NEARLY HIT BY AN ONCOMING VEHICLE. TWO WEEKS AGO PROBLEM OCCURED WHILE I WAS IN A FUNERAL PROCESSION GOING THROUGH AN INTERSECTION THE VEHICLE BEHIND ME HAD TO SWERVE TO AVOID A REAR END COLLISION..I DO NOT FEEL SAFE DRIVING A CAR I PAID 50,000 FOR.. *TR

VEHICLE BECAME INOPERATIVE WHILE DRIVING ON A HIGHWAY. HAPPENED TWICE TODAY ON SPEEDS OF 60+ MPH IN HEAVY TRAFFIC. VEHICLE DECELERATED QUICKLY AND LOST SPEED, I WAS LUCKY TO AVOID COLLISIONS. THE CONSOLE POPPED UP FLASHING MESSAGE 'PRE-SAFE FUNCTIONS LIMITED' ON THE CONSOLE. THE VEHICLE DID NOT RESPOND TO ACCELERATOR. AFTER SWITCHING THE IGNITION OFF AND ON AGAIN, THE PROBLEM TEMPORARY DISAPPEARED, BUT THEN HAPPENED AGAIN. THE VEHICLE IS DULY SERVICED AND IS STILL ON WARRANTY, THERE WAS NO ACCIDENTS OR MECHANICAL FAULTS PRIOR TO DATE. SCARY AND VERY DANGEROUS. COULD HAVE EASILY INJURED MYSELF OR SOMEONE ELSE WHO WOULD HAVE HIT THE VEHICLE WHICH SUDDENLY BECOMES INOPERATIVE.

I AM WRITING TO RAISE SERIOUS CONCERNS ABOUT THE RUN-FLAT TIRES INSTALLED ON MY 2014 CLA 250. AFTER 12,830 MILES, I EXPERIENCED MY FIRST FLAT TIRE. AFTER CONSULTING THE OWNER'S MANUAL, I LEARNED THAT I HAD RUN-FLAT (MOEXTENDED) TIRES AND COULD PROCEED (HAVING THE ABILITY TO DRIVE 50 MILES ON THE FLAT, ACCORDING TO MY MANUAL). I WAS SHOCKED TO LEARN THAT THIS TIRE, COULD NOT BE REPAIRED AND THAT MY ONLY OPTION WAS TO PURCHASE A NEW TIRE. ON 8/29/16, I WAS TRAVELING SOUTH ON HIGHWAY 101 IN A VERY RURAL PART OF HUMBOLDT COUNTY IN NORTHERN CALIFORNIA, AND EXPERIENCED ANOTHER FLAT TIRE (AGAIN WITH ONE OF THE FACTORY INSTALLED TIRES). FROM A DESERTED GAS STATION IN A PLACE CALLED WEOTT, I TRIED TO CALL MERCEDES-BENZ ROADSIDE ASSISTANCE BUT AFTER BEING PUT ON HOLD AND TRYING TO NAVIGATE THE MENU, I GAVE UP. I KNEW THAT THERE WERE ONLY SMALL TOWNS FOR APPROXIMATELY 75 MILES SOUTH OF ME, SO I CHOSE TO RETURN TO FORTUNA (WHERE MY SISTER LIVED), APPROXIMATELY 20 MILES TO THE NORTH). THE MILEAGE AT THE TIME OF THIS FLAT WAS 22, 684. JUST A FEW MILES AWAY FROM MY DESTINATION, I PULLED OVER BECAUSE THE VIBRATION IN THE CAR HAD TURNED TO SHAKING AND I WAS FINDING IT VERY DIFFICULT TO CONTROL MY VEHICLE. I BECAME FRIGHTENED THAT I MIGHT LOSE CONTROL. I MUST REITERATE THAT AT THIS POINT I WAS EXTREMELY FRIGHTENED FOR MY SAFETY AND PULLED OVER ON THE SIDE OF HIGHWAY 101 AND CALLED FOR A TOW TRUCK. I HAD DRIVEN CAUTIOUSLY FOR ONLY 25 MILES ON THE FLAT TIRE, NOTHING NEAR THE 50 MILES PROMISED IN MY AUTO MANUAL. AT THE TIRE CENTER, I OPTED TO PURCHASE TWO NON RUN FLAT TIRES. 1) IS THERE A QUALITY ISSUE THAT NEEDS TO BE INVESTIGATED REGARDING THE FACTORY INSTALLED MOEXTENDED TIRES? 2) CLEARLY THE MOEXTENDED TIRES ARE NOT DESIGNED TO BE RUN WHEN FLAT FOR 50 MILES, AND THAT NEEDS TO BE CHANGED IN THE AUTO MANUAL. *TR

MY CAR WAS PURCHASED 8/2014 FROM MERCEDES BENZ OF HENDERSON NV. THIS CAR HAS HAD PROBLEMS THE1ST DAY OF OWNING IT. THIS CAR HAS BEEN IN AND OUT OF THE SHOP SO MANY TIMES THAT I HAVE LOST COUNT. I HAVE A FOLDER AS THICK AS MY BIBLE. MERCEDES WON'T CLAIM IT AS A LEMON AND THIS CAR HAS BEEN IN THE SHOP FOR THE SAME PROBLEMS WITH ADDITIONAL PROBLEMS EVERY TIME IT IS TAKEN IN. THE DEALERSHIP WILL NOT EXCHANGE IT FOR A EQUAL CAR WITHOUT THE OPTION OF RENEWING ANOTHER LEASE AND INCREASING THE PAYMENT. I HAVE EXPERIENCED HAZARD LIGHTS ON THE FIRST 30MILES. THE ELECTRICAL WENT OUT/WARNING FLASHERS/MALFUNCTIONING/INOPERABLE THE CAR HAS DIED DRIVING WHICH PUT MINE AND OTHERS LIVES IN DANGER. ALL I'M TOLD IS I AM SORRY. I AM DRAINED WITH DEALING WITH THE DEALERSHIP AND GOING THROUGH ALL OF THEIR TURNOVERS WITH MNGMNT. PABLO RODRIGUEZ WAS A GEM ALONG WITH BUTCH WHO DID NOTHING!!EVERY CODE THAT WAS DCMNTD WAS DELETED FROM THE MEMORY. MY CAR WAS RECENTLY IN AGAIN WITH INOPERABLE/MALFUNCTIONING DISPLAY/ACCELERATION/PRE SAFE SYSTEM ERROR IN WHICH THEY SAID THEY FIXED BUT LESS THE 24HRS THE SAME PROBLEM OCCURRED. THE DEALERSHIP HAD MY CAR FROM JUNE 24TH TO JULY 10TH AND SAME ISSUES BUT NEW ERROR MESSAGES. I HAVE BEEN WITHOUT A CAR SINCE I PICKED IT UP AND THE DEALERSHIP WILL NOT DO ANYTHING ABOUT GETTING IT IN SOONER THEN THE 25TH. THEY DON'T CARE AT THIS DEALERSHIP NOR DOES MERCEDES CORP. HRS & HRS OF WASTED TIME TALKING TO PEOPLE WHO CAN DO NOTHING.NO CALLS FROM ANYONE, I RECEIVED SURVEYS IN THE BEGINNING THAT WERE NEVER ADDRESSED I KNOW THAT BECAUSE OF MY FEEDBACK. IVE NEVER EXPERIENCED ANYTHING LIKE THIS BEFORE AND IT IS SO DISAPPOINTING. OVERALL IT HAS A BEEN THE VERY WORST EXPERIENCE THAT IVE EVER HAD OWNING A CAR!!! OR MERCEDES THAT IS.

I HAVE HAD THE SAME ISSUE AS MANY OTHERS. I WAS DRIVING MY CAR DOWN THE HIGHWAY IN THE LEFT LANE AT 65 MPH. ALL OF A SUDDEN THE SPEEDOMETER DROPPED TO 0 AND I COULD NOT ACCELERATE. I HAD TO PULL OVER TO THE SIDE OF THE ROAD AND TURN OFF THE CAR. THIS FIRST HAPPENED TO ME TWICE IN DECEMBER 2013. I TOOK IT INTO THE DEALERSHIP AND THEY DID SEVERAL THINGS TO TRY AND FIX IT. THEY TOLD ME THEY UPDATED THE SOFTWARE. I WAS SCARED TO CONTINUE DRIVING THE CAR, BUT THEY ASSURED ME IT WOULDN'T HAPPEN AGAIN. BUT, THE SAME ISSUE JUST HAPPENED TO ME AGAIN (JUNE 2016). WHY HASN'T MERCEDES DONE ANYTHING TO FIX THIS? I DON'T WAN TO DRIVE A CAR THAT LOSES SPEED WHILE I'M ON A BUSY HIGHWAY, IT'S NOT SAFE.

THE VEHICLE WILL STOP ACCELERATION WHILE DRIVING. THE MESSAGE STATES "PRE-SAFE FUNCTIONS LIMITED". WHEN THE CAR SHUTS OFF FOR NO APPARENT REASON WHEN DRIVING AT 70 MPH ON A HIGHWAY IS REALLY UNSAFE. I HAVE TO COAST TO THE SIDE OF THE ROAD TO SAFETY. I HAVE TURN THE VEHICLE OFF AND THEN I WILL BE ABLE TO RESTART THE ENGINE. I HAVE NOT TAKEN THIS INTO MY MERCEDES DEALERSHIP YET.

TL* THE CONTACT OWNS A 2014 MERCEDES-BENZ CLA250. WHILE DRIVING AT VARIOUS SPEEDS, THE INOPERABLE PRE-SAFE WARNING LIGHT ILLUMINATED AND THE VEHICLE BEGAN TO STALL. THE FAILURE WAS PERSISTENT. WHILE THE ACCELERATOR PEDAL WAS DEPRESSED, THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS ABLE TO RESTART. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE PINS FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS APPROXIMATELY 24,000. THE VIN WAS NOT AVAILABLE.

TL* THE CONTACT OWNS A 2014 MERCEDES-BENZ CLA250. WHILE DRIVING 25 MPH, THE VEHICLE LOST POWER. THE ACCELERATOR PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO ACCELERATE. THE BRAKE, ESC, AND MULTIPLE WARNING LIGHTS ILLUMINATED. THE VEHICLE WAS TAKEN TO A DEALER, BUT THE CONTACT WAS UNSURE ABOUT WHAT PART WAS REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHO WAS UNABLE TO DIAGNOSE OR REPAIR THE VEHICLE. THE FAILURE PERSISTED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 40,000.

MULTIPLE EPISODES OF "PRE-SAFE FUNCTIONS LIMITED" OCCURRING. WHEN THIS MESSAGE APPEARS THE CAR SUDDENLY LOSES ACCELERATION AND YOU ARE NOT ABLE TO GO ABOVE 30 MPH DESPITE PRESSING ON THE GAS PEDAL. THIS HAS OCCURRED ON NORMAL 35-45 MPH STREETS BUT HAS HAPPENED MULTIPLE TIMES ON THE HIGHWAY WHEN THE CAR IS GOING 65 MPH. LUCKILY, NO MOTOR VEHICLE ACCIDENTS HAVE OCCURRED BECAUSE OF THIS ISSUE. THE CAR IS ABLE TO ACCELERATE AND FUNCTION NORMALLY AFTER TURNING THE ENGINE OFF AND ON AGAIN. HAVE GONE TO MERCEDES DEALER MULTIPLE TIMES TO FIX ISSUE. THE FIRST TIME IT OCCURRED, MERCEDES UPDATED SYSTEM SOFTWARE. NEXT THEY REPLACED VEHICLE SENSORS. MOST RECENTLY THEY CLAIMED THE ISSUE WAS DUE TO OIL PUMP FAILURE. THEY REPLACED AN OIL CONTROL VALVE AND OIL PAN. FOUR DAYS AFTER THE REPAIR I RECEIVED THE SAME "PRE-SAFE FUNCTIONS LIMITED MESSAGE, MY CAR STALLED WHILE I WAS GOING 40 MPH. I HAVE RETURNED THE CAR TO THE DEALER ONCE AGAIN TO RUN DIAGNOSTICS. THIS HAS OCCURRED MANY TIMES IN THE TWO AND A HALF YEARS THAT I'VE OWNED THE VEHICLE. IT IS CURRENTLY AT 49,200 MILES AND HAS BEEN PROPERLY SERVICED. EACH TIME I BRING THE CAR IN FOR THIS ERROR MESSAGE MERCEDES REPLACES A NEW PART BUT IT DOES NOT SOLVE THE PROBLEM.

ON MULTIPLE OCCASIONS, THE VEHICLE WILL SHUT OFF WHILE DRIVING. THE MESSAGE STATES "PRE-SAFE FUNCTIONS LIMITED". WHEN THE CAR SHUTS OFF FOR NO APPARENT REASON, I HAVE TO COAST TO THE SIDE OF THE ROAD TO SAFETY. I HAVE TURN THE VEHICLE OFF AND THEN I WILL BE ABLE TO RESTART THE ENGINE. I'VE ALREADY TAKEN THIS INTO MY MERCEDES DEALERSHIP AND THEY DID NOT FIX THE ISSUE. I'M AFRAID THIS IS GOING TO CAUSE A FATAL ACCIDENT AND I HAVE TWO SMALL CHILDREN. PLEASE MAKE THIS A HIGH PRIORITY

I HAVE HAD THE SAME ISSUE OF THE CAR, BEING IN PARK FOR OVER 5-10 MINUTES, SUDDENLY LUNGING FORWARD. IT IS QUIET STARTLING TO HAVE IT HAPPEN. I WORRY THAT WHEN I EXIT THE CAR WITH THE ENGINE RUNNING ( DUE TO PASSENGERS STILL IN THE CAR) SOMETHING WILL HAPPEN. THIS HAS HAPPEN SEVERAL TIMES WITH ME.

WHILE DRIVING AT HIGHWAY SPEED THE ACCELERATOR PEDAL SUDDENLY FAILED. THE ENGINE WOULD NOT RESPOND TO ANY INPUT OF THE GAS PEDAL. I PUMPED THE PEDAL, FLOORED THE PEDAL ALL WITH NO RESPONSE. THE ENGINE WOULD NOT REV PAST IDLE AND THE CAR LOST SPEED MAKING CHANGING LANES DIFFICULT AND DANGEROUS. THE ERROR MESSAGES SHOWN IN THE PHOTOS APPEARED IN THE DASHBOARD. THIS HAS HAPPENED TWICE (11/30/15 AND 12/6/15).

BOUGHT BRAND NEW CLA250 A YEAR AGO AND DRIVING LAST WEEK ON THE HIGH WAY AND "INOPERATIVE MODE" WENT ON AND YOU LOSE ALL ACCELERATION POWER. AFTER I PULLED OVER FINALLY RESTARTING THE CAR A FEW TIMES I REGAINED ACCELERATION. CURRENTLY AT DEALER BEING ASSESSED

WHILE TRAVELING AT 50MPH DOWN A BUSY STREET DURING MY MORNING RUSH HOUR COMMUTE, THE VEHICLE CUT OFF ALL POWER AND WENT INTO "PRE-SAFE MODE" WHICH IS COMMONLY KNOWN AS "LIMP HOME MODE." WHEN THIS HAPPENS, THE DRIVER HAS NO ABILITY TO ACCELERATE AND IF THE DRIVER IS UNABLE TO PULL OVER IN A SAFE AREA, PUTS THEM AT EXTREMELY HIGH RISK OF SERIOUS ACCIDENT. THIS IS A COMMON PROBLEM WITH MANY MERCEDES BENZ VEHICLES THAT ARE EQUIPPED WITH ESP (TRACTION CONTROL). A SIMPLE GOOGLE SEARCH OF THIS ISSUE WILL VALIDATE THIS AS A WIDESPREAD MAJOR DESIGN FLAW IN MERCEDES BENZ PRODUCTS. PLEASE TAKE THE TIME TO LOOK INTO THIS EXTREMELY DANGEROUS PROBLEM, AS MANY OTHER MERCEDES OWNERS HAVE EXPERIENCE THIS IN MORE DANGEROUS CIRCUMSTANCES (ON THE HIGHWAY).

BOUGHT THE CLA 250 BRAND NEW IN 2014, VEHICLE HAS NOW TWICE GONE IN TO PRE-SAFE MODE AND INOPERATIVE MODE WHILE DRIVING. THE CAR SWITCHES TO NEUTRAL AS I AM DRIVING AND THEN REFUSES TO SHIFT IN TO DRIVE OR REVERSE LEAVING ME STRANDED IN THE STREETS ON TWO OCCASION WHICH COULD HAVE CAUSED TWO VERY SERIOUS ACCIDENTS. THE CAR ON THE SECOND TIME HAD TO BE TOWED TO DEALERSHIP WHO COULD'NT FIND ANYTHING WRONG WITH THE CAR. THERE SOLUTION WAS MORE OF A GUESS ABOUT A CPU NEEDING TO BE REPLACED.

MY CAR SUDDENLY SLOWED AND I LOST POWER WHILE DRIVING ON 95 AT APPROXIMATELY 20-30 MPH IN SLOW HEAVY TRAFFIC TO WORK THIS MORNING. I COULD HARDLY ACCELERATE AND ONLY SLOWLY... I HAD MESSAGES THAT SAID "PRE-SAFE FUNCTIONS INOPERATIVE. SEE OPERATOR'S MANUAL", AND THE ESC LIGHT CAME ON. DRIVERS BEHIND ME STARTED PASSING ME DESPITE ME ALREADY GOING SLOWLY DUE TO ALL THE TRAFFIC--I HAD NO WHERE TO PULL OVER AND CRAWLED INTO THE PARKING RAMP AT WORK. I COULD HAVE BEEN REAR-ENDED THIS MORNING. I HAVE NO IDEA WHAT WILL HAPPEN WHEN I RESTART THE CAR TODAY. THIS NEEDS TO BE TAKEN CARE OF BY MERCEDES--DO A RECALL AND FIX THIS ISSUE!

MAKING NOISES LIKE RATTLING OR VIBRATION DURING DRIVING.

BROUGHT CLA250 6/2015 AFTER THREE MONTHS LOSS POWER, ENGINE LIGHT CAME ON CAR DECELERATED. TOOK VEHICLE TO THE DEALERSHIP AFTER 3 DIFFERENT INCIDENTS, TO BE TOLD THERE WAS A SERVICE BULLETIN ON MY CAR. WILL KEEP YOU POSTED AFTER PICK UP. CAR WAS AT THE STOP LIGHT AND THE VEHICLE DECELERATION WENT DOWN.

CAR HAS NOW TWICE GONE INTO PRE-SAFE FUNCTIONS LIMITED AND INOPERATIVE MODE (SIMULTANEOUSLY) WHILE DRIVING WITH NO NOTICE, EFFECTIVELY REMOVING ALL ABILITY TO ACCELERATE AND CREATING NEAR MAJOR ACCIDENTS BOTH TIMES. THE FIRST TIME OCCURRED ON THE FREEWAY DRIVING IN THE SECOND TO THE LEFT LANE AT APPROX 75 MPH. CARS NARROWLY AVOIDED CRASHING INTO ME WHILE I COASTED THROUGH HIGH SPEED TRAFFIC TO THE SHOULDER. THE SECOND TIME WAS IN TOWN AND WITHOUT WARNING SAME THING OCCURRED LEAVING ME COASTING IN THE LEFT LANE WITH A TRUCK NARROWLY AVOIDING A COLLISION AND THE TRUCK HAVING TO GO INTO ONCOMING TRAFFIC AND BACK TO AVOID ME. AS THERE WAS NO SHOULDER I HAD TO NAVIGATE AND COME TO A STOP IN THE RIGHT LANE OF TRAFFIC.

PURCHASED MY NEW CLA250 IN SEPTEMBER 2014. IN AUGUST OF 2015 MY CAR SUDDENLY STOPPED ACCELERATING WHILE DRIVING 65MPH ON THE NJ GARDEN STATE PARKWAY!. THE PRE-SAFE WARNING WAS PRESENT ON MY DASHBOARD. LUCKILY I WAS ABLE TO PULL TO THE SHOULDER WITHOUT CAUSING AN ACCIDENT. THIS COULD HAVE CAUSED A MAJOR CATASTROPHE KILLING ME AND OTHERS. I RESTARTED THE ENGINE AND DROVE TO MY DESTINATION MAKING SURE I STAYED IN THE RIGHT LANE ON THE PARKWAY. IT FAILED 2 MORE TIMES WHILE NOT ON THE HIGHWAY BUT STILL A VERY DANGEROUS SITUATION. TOOK THE CAR (WHICH HAD 16,000 MILES) TO A MERCEDES DEALERSHIP WHEN I RETURNED AND THEY PERFORMED A SERIES OF TESTS. THEY FOUND A PRODUCT TECHNICAL SUPPORT SYSTEM UPDATE WHICH INVOLVED UPDATING THE SOFTWARE. THE FAILURE DID NOT OCCUR AGAIN UNTIL NOV. 2017. I ALMOST GOT HIT BY A BUS IN PHILADELPHIA WHEN MY CAR DECIDED TO STOP ACCELERATING. FINALLY, DRIVING TO THE AIRPORT DOING 70MPH THE CAR AGAIN DISPLAYED THE PRE-SAFE WARNING AND RAPIDLY SLOWED DOWN ALMOST CAUSING A CRASH ON I-78 IN NJ. TOOK THE CAR TO A MERCEDES DEALERSHIP NEAR ME AND THEY SAID SINCE THE CAR IS 2,000 MILES BEYOND THE 50,000 MILE WARRANTY IT'S NOT COVERED. THEY ARE REPLACING A SERIES OF PARTS THAT WILL COST ME OVER $4,000 TO REPAIR! THERE IS NO GUARANTEE THIS WILL EVEN FIX THE PROBLEM. IS MERCEDES WAITING FOR SOMEONE TO DIE BEFORE THEY ACKNOWLEDGE THIS CAR HAS A VERY SERIOUS PROBLEM? I HAVE TO WONDER IF THERE HAS BEEN ANY CRASHES INVOLVING THIS CAR AND NOBODY SURVIVED TO DETAIL WHAT WAS HAPPENING! THE 2014 CLA IS NOT SAFE AND MERCEDES DOESN'T APPEAR TO BE CONCERNED.

WHILE DRIVING ON THE HIGHWAY, I HEARD A SUDDEN LOUD EXPLOSION, THE PANORAMA SUNROOF SHATTERED AND GLASS RAINED DOWN ON ME AND EVERYWHERE WITHIN THE CAR. THERE WAS NO EVIDENCE OF ANYTHING HITTING THE CAR OR THE SUNROOF, IT JUST SPONTANEOUSLY EXPLODED.

I WAS DRIVING SOUTH ON US 41 IN LAKE FOREST IL WHEN THE SUNROOF SUDDENLY EXPLODED. THE FABRIC SUNSCREEN WAS ON AND PREVENTED THE GLASS FROM HITTING THE DRIVER OR PASSENGERS.THERE WERE NO BRIDGES IN THE AREA. NOTHING HIT OUR WINDSHIELD EITHER. PHOTOS OF THE DAMAGE SHOWED NO EVIDENCE OF ROCKS OR OTHER OBJECTS MIXED IN WITH THE GLASS FRAGMENTS.COPIES OF THE PHOTOS ARE AVAILABLE BY REQUEST. WE ARE CONCERNED THE SUNROOF WAS DEFECTIVE AND IS A SAFETY HAZARD...UPDATED 10/27/15 *BF UPDATED 11/22/2017*CN

TL* THE CONTACT OWNS A 2014 MERCEDES BENZ CLA250. WHILE ATTEMPTING TO REVERSE, THE STEERING WHEEL SEIZED. IN ADDITION, THE POWER STEERING MALFUNCTION, SEE MANUAL WAS DISPLAYED ACROSS THE MESSAGE BOARD. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 11,000. THE VIN WAS UNAVAILABLE.

WHILE DRIVING MY CLA THAT I HAVE ONLY HAD 4 MONTHS THE CAR TURNED OFF AND SAID IT'S INOPERABLE! I WAS ALMOST HIT MULTIPLE TIMES, WHEN DROPPED IT OF AT DEALER THEY WOULDN'T EVEN GIVE ME A LOAN. I BOUGHT THIS CAR BRAND NEW! *TR

RECENTLY, EVERY TIME I MA DRIVING IN THE RAIN, NO MATTER HOW LIGHT THE RAIN IS, THE TRACTION CONTROL LIGHT COMES ON AND A MESSAGE STATING"PRE SAFE, FUNCTIONS LIMITED, INOPERATIVE" SHOWS UP. THE VEHICLE HAS LOOSES ACCELERATION. THIS HAPPENED TO ME ON THE FREEWAY TODAY. THIS IS POTENTIALLY DANGEROUS AS IT COULD CAUSE A SERIOUS ACCIDENT. THIS SEEMS TO BE A RECURRENT PROBLEM BASED ON A SIMPLE ONLINE SEARCH. *TR

INOPERATIVE - PRE-SAFE FUNCTIONS LIMITED - I'VE HAD THIS ERROR COME UP 3X SO FAR, IT HAPPENED 2X JUST LAST NIGHT ON A 10 MINUTE DRIVE. FIRST TIME WAS ON THE FREEWAY, HAD TO PULL OVER TO THE SHOULDER AND RESTARTED THE CAR. THE 2X OTHER TIMES HAPPENED LAST NIGHT, DRIVING 10MINS IN THE EVENING, BOTH HAD TO PULL OVER AND RESTART. THE SECOND TIME, MY CHECK ENGINE LIGHT CAME UP. I HOPE THIS IS ADDRESSED QUICKLY AS I CAN SEE THAT THE COMPLAINTS ARE PILING UP ON HERE. *TR

INOPERABLE MESSAGE FLASHED ON THE DASH AS I LOST ALL ACCELERATION POWER. WAS ALMOST REAR ENDED BY A SEMI, BUT WAS ABLE TO PULL OVER TO THE SIDE OF THE INTERSTATE. LUCKILY I WAS NOT IN HEAVY TRAFFIC AT THE TIME AND DIDN'T GET HIT. THIS HAS HAPPENED 3 TIMES NOW AND I AM STILL WAITING FOR MB TO GET BACK TO ME. *TR

I WAS DRIVING AND ALL OF A SUDDEN THE PRE SAFE MODE POPPED UP SAYING "INOPERATIVE" AND "SEE OWNERS MANUAL". THE CHECK ENGINE LIGHT CAME ON AS WELL AS SOME SORT OF TRACTION CONTROL LIGHT. I WAS NEARLY IN A ACCIDENT BECAUSE THE CAR WOULDN'T ACCELERATE. WHEN GETTING STOPPED AT A RED LIGHT THE CAR WOULD NOT ACCELERATE AFTER PUSHING THE PEDAL. THEN IT WOULD ACCELERATE REAL FAST. LUCKILY I WAS ONLY 20 MINUTES FROM MY LOCAL MERCEDES DEALER SO I CALLED THEM AND TOLD THEM I WAS BRINGING THE CAR DIRECTLY TO THEM. THIS IS VERY SCARY AND FROM SEEING OTHER COMPLAINTS THERE MUST BE SOMETHING THAT NEEDS TO BE ADDRESSED. *TR

VEHICLE SUDDENLY LOST POWER WHILE DRIVING AT APPROXIMATELY 30 MPH. ONLY ABLE TO ACCELERATE VERY SLOWLY. MESSAGES "INOPERATIVE SEE OPERATOR'S MANUAL" AND "PRE-SAFE FUNCTIONS LIMITED" DISPLAYED. IT IS UNSAFE THAT CAR SUDDENLY DECELERATES WITHOUT WARNING TO SURROUNDING DRIVERS. THIS HAS HAPPENED ON TWO SEPARATE OCCASIONS A FEW DAYS APART. *TR

ACCELERATING FROM AN INTERSECTION AFTER THE LIGHT TURNED GREEN, THE ENGINE BEGAN CHUGGING AND THUMPING. THE CHECK ENGINE LIGHT CAME ON IMMEDIATELY AND THE ECO LIGHT STARTED FLASHING . THE ENGINE STALLED SEVERAL TIMES. WE DROVE STRAIGHT TO THE DEALERSHIP WITH THE CAR. AT EVERY INTERSECTION WITH A RED LIGHT, IT SEEMED AS THOUGH THE CAR WOULD STALL AGAIN. WE DID MAKE IT TO THE DEALERSHIP. THEY KEPT IT FOR THREE DAYS, AND DETERMINED THAT IT WAS A DEFECTIVE MANIFOLD PRESSURE SENSOR. THIS IS THE SECOND TIME THE MANIFOLD PRESSURE SENSOR HAS HAD TO BE REPLACED. IN THE FIRST EPISODE ON OCTOBER 9TH, 2014, THE CAR DIED COMPLETELY AND THE MESSAGE "INOPERABLE" APPEARED IN THE MESSAGE SCREEN. THE CAR HAD TO BE TOWED IN THAT TIME. BOTH INSTANCES REQUIRED REPLACEMENT OF THE SAME SENSOR AND AN UPDATE TO THE SOFTWARE. *TR

CAR INABILITY TO,ACCELERATE PRE SAFE LIGHTS COME ON AND CHECK ENGINE LIGHT COME ON. *TR

TL*THE CONTACT OWNS A 2014 MERCEDES BENZ CLA250. THE CONTACT STATED THAT WHILE DRIVING AT 70 MPH, THE ENGINE STALLED AND THE CHECK EMERGENCY WARNING LIGHT ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED.THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 4,800.

I LEASE A 2014 MERCEDES BENZ CLA250. WHILE DRIVING AT 70 MPH, THE ENGINE STALLED AS THE MESSAGE BOARD DISPLAYED INOPERATIVE PRE SAFE FUNCTIONS LIMITED SEE OWNERS MANUAL. ADDITIONALLY, THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS DIAGNOSED AND REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 1600. *TR

THE CAR SHOWED "PRE-SAFE UNAVAILABLE" AND SHOWED THAT THE STABILITY CONTROL OFF LIGHT ON THE DASH. IT WENT INTO "LIMP" MODE JUST BEFORE A DANGEROUS Y SHAPED INTERSECTION WHERE I WAS TURNING TO THE LEFT LEG OF THE Y AND THE ONCOMING TRAFFIC WAS FROM THE RIGHT SIDE OF THE Y. THE CAR WAS ALMOST TOTALLY UNRESPONSIVE TO THROTTLE INPUTS, AND AS I HAD TO SLOW DOWN TO SEE DOWN THE HILL TO THE RIGHT SIDE OF THE Y, ACCELERATION ACROSS THE INTERSECTION WAS LESS THAN NORMAL WALKING SPEED. LUCKILY, THERE WAS NO TRAFFIC COMING TO THE RIGHT OR BEHIND ME. DEALER WAS UNABLE TO FIND THE CAUSE. I TRADED THE CAR IN FOR THE NEXT YEAR MODEL DUE TO FEELING UNSAFE DRIVING IT. *TR

CAR HAD NO ACCELERATION WHILE DRIVING IN TRAFFIC ON A MAJOR PARKWAY. VEHICLE INOPERABLE PRE SAFETY FEATURES DISABLED FLASHED ON THE MESSAGE CENTER. ENGINE LIGHT ALSO CAME ON. VEHICLE TAKEN TO BE SERVICED AND THE ACCELERATOR MODULE REPLACED. MY CAR SEEMED OKAY UNTIL IT HAPPENED 4 MORE TIMES AGAIN WHILE DRIVING ON A PARKWAY. THIS OCCURRED APPROXIMATELY 5 WEEKS AFTER THE CAR WAS "FIXED". SAME EXACT PROBLEM AND MESSAGE. IS MB WAITING FOR SOMEONE TO GET KILLED? SO MANY PEOPLE HAVING THE SAME PROBLEM. I DON'T NEED TO GET IN AN ACCIDENT. I THOUGHT I WAS BUYING A SAFE DEPENDABLE VEHICLE WITH EXCEPTIONAL SERVICE. I SHOULD HAVE KEPT MY SONATA. I'M REALLY AFRAID TO DRIVE THIS CAR AGAIN ONCE I GET IT BACK. *TR

I WAS DRIVING ON A BUSY SURFACE STREET IN LOS ANGELES WHEN MY CAR LOST ALL ACCELERATION AND THE MESSAGE POPPED UP, "INOPERABLE, SEE MANUAL". I TRIED TO PUSH THE GAS PEDAL TO QUICKLY MOVE OVER TO THE RIGHT LANE WHERE I COULD PUT ON MY HAZARD LIGHTS BUT I COULD NOT ACCELERATE. I TURNED OFF THE CAR QUICKLY AND STARTED IT AGAIN AND IT WENT BACK TO WORKING FOR NOW. I AM TERRIFIED FOR THIS TO HAPPEN AGAIN, ESPECIALLY BECAUSE IF IT HAPPENED ON A LOS ANGELES FREEWAY, I COULD EASILY BE KILLED. I AM 8 MONTHS PREGNANT AND FEAR FOR MY SAFETY AND THE SAFETY OF MY CHILD. *TR

CAR HAS BEEN LUNGING FORWARD WHEN IN PARKED FOR MORE THAN 5 TO 10 MIN SINCE I HAVE OWNED THE CAR. THIS CAR WAS BOUGHT ON FEBRUARY 20, 2015. SINCE THEN, I HAVE BROUGHT IT BACK TO THE DEALERSHIP 3 TIMES FOR THE SAME PROBLEM. THE THIRD TIME THAT I BROUGHT IT TO THEM, THEY FOLLOWED UP WITH SAYING THAT IT IS THE MAKE OF THE CAR AND EVERY CLA DOES THAT. THIS IS A HUGE SAFETY PROBLEM AND IT NEEDS TO BE FIXED.

WHILE DRIVING ON THE HIGHWAY WITHOUT NOTICE MY CAR COMPLETELY SHUT OFF. SEVERAL NOTIFICATIONS APPEAR ON THE DASH SCREEN "INOPERABLE SEE OWNERS MANUAL" THIS IS THE 2ND TIME IN TWO DAYS WHERE THIS SAME DANGEROUS LIFE THREATENING ISSUE OCCURRED. *TR

SINCE I BOUGHT THIS CAR BRAND NEW IN DECEMBER 2014, I HAVE HAD TO REPLACE ALL 4 TIRES AT LEAST TWICE EACH. THEY CONSTANTLY GET BUBBLES ON THE SIDEWALLS. I HAVE THE SPORTS EDITION, SO I HAVE THE GOODYEAR RUNSFLATS WHICH COST OVER $350 EACH.

SUMMARY: PRE-SAFE FUNCTION LIMITED MESSAGE AND ESP LIGHTS APPEARED ON THE DASH AND MY CAR STOPPED IN THE MIDDLE OF THE HIGHWAY. ALMOST GOT TAKEN OUT BY AN 18 WHEELER. I TRIED HARD TO MOVE OVER TO THE SHOULDER. I TURNED OFF THE CAR AND TURNED IT BACK ON. IT WORKED AFTER THAT. THEN IT HAPPENED 40 MINUTES LATER. VERY BIG SAFETY ISSUES WITH THIS CAR. THIS HAPPENED 5 TIMES IN 5 DAYS. *TR

PRE-SAFE FUNCTION MESSAGE AND ESP LIGHTS APPEARED AND THE CAR STOPPED ALLOWING ME TO ACCELERATE IN THE MIDDLE OF TRAFFIC. I HAD TO TRY TO MOVE OVER TO THE SIDE OF THE RODE. AFTER MOVING TO THE SIDE, I TURNED OFF THE CAR AND TURNED IT BACK ON. IT WORKED AFTER THAT. *TR

THE PRE SAFE MODE HAS HAPPENED 5 TIMES ON MY CLA 250 SINCE I BOUGHT THE CAR LAST JANUARY. I THINK THE PRE SAFE MODE IS NOT SAFE AT ALL. ALL OF A SUDDEN, THE CAR JUST LOST POWER, NO ANY FEEDBACK WHEN I STEPPED THE GAS PEDAL, THE BEST THING IS THE BRAKE STILL WORKED. AFTER RESTARTING THE CAR, THE CAR WENT WELL BUT THE ENGINE LIGHT WAS ON. HOWEVER, AFTER TWO DAYS, THE ENGINE LIGHT WAS OFF SO I DIDN'T EVEN HAVE A CHANCE TO SHOW TO THE DEALER. IT'S VERY DANGEROUS TO DRIVE THIS CAR ON HIGH WAY, ESPECIALLY IN TRAFFIC JAM. *TR

TIRES LOSE AIR ALL DURING THESE 3 YRS THAT I HAD THIS CAR LEASE, ALWAYS AT THE DEALER, I'M AFRAID FOR MY SAFETY DUE TO THE IMBALANCED TIRE PRESSURE. CAN'T MAKE PLANS TO DRIVE IT FAR, AFRAID TIRES MIGHT CAUSE ME TO LOSE CONTROL AND CREATE AN ACCIDENT!! MANY TIMES I CAN'T GO RIGHT AWAY, BECAUSE IT TAKES TIME OUT OF MY LIFE.... I WORK 12 HOUR DAYS, I BOUGHT THIS LUXURY CAR FOR ITS NAME AND ITS RELIABLE , ACTUALLY IT'S THE OPPOSITE BECAUSE THEY ARE NOT ABLE TO FIX IT!!! FRUSTRATED!!

VEHICLE'S TRANSMISSION & THROTTLE RESPONSE IS JERKY & UNPREDICTABLE. ROTORS WENT BAD AT 5,000 MILES, BEGINNING TO GO BAD AGAIN AT 12,000. NUMEROUS UNKNOWN INTERIOR RATTLES.WINDSHIELD WIPER COMPLETELY FLEW OFF VEHICLE WHILE DRIVING IN HEAVY RAIN - VISIBILITY INSTANTLY REDUCED TO NEAR-ZERO. ON TWO OCCASIONS, THE CAR DISPLAYED "PRE-SAFE FUNCTIONS LIMITED/ESP INOP" MESSAGE FOLLOWED BY ENGINE IMMEDIATELY LOSING POWER ON FREEWAY, WHICH COULD HAVE ENDED VERY BADLY. NOT ONLY IS THIS VEHICLE OF POOR QUALITY, IT IS BECOMING INCREASINGLY DANGEROUS TO DRIVE. SERIOUSLY CONSIDERING PURSUING STATE LEMON LAW. *TR

VEHICLE LOST ACCELERATION TWICE WITHIN A QUARTER MILE DISTANCE ON FREEWAY AFTER APPROXIMATELY 10 MINUTES OF DRIVING TIME. THIS IS A SECOND OCCURRENCE OF SAME PROBLEM. VEHICLE DISPLAYED PRE-SAFE INOPERATIVE ERROR MESSAGE. AFTER PULLING OVER AND RESTARTING THE ENGINE, THE ISSUE WAS RESOLVED FOR A SHORT DISTANCE. THE VEHICLE WAS TOWED TO THE DEALERSHIP WHERE THE ENTIRE ACCELERATOR PEDAL ASSEMBLY WAS REPLACED. MY FAMILY IS VERY SKEPTICAL OF THIS CARS RELIABILITY AND IS SEEKING OPTIONS WITH ATTORNEY UNDER STATE LEMON LAWS. *TR

TL* THE CONTACT OWNS A 2014 MERCEDES BENZ CLA250. THE CONTACT STATED THAT WHILE DRIVING AT APPROXIMATELY 40 MPH, THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE SENSOR SOFTWARE FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 20,000.

PULLING OUT INTO A BUSY TWO LANE HIGHWAY THE3 CAR WENT INTO "PRE-SAFE MODE." THE CAR STOPPED ACCELERATING LEAVING ME STRANDED IN FRONT OF ONCOMING TRAFFIC. THE DRIVE OF THE OTHER CAR THANKFULLY WAS PAYING ATTENTION AND HIT HIS BRAKES. THIS COULD HAVE BEEN A VERY PAINFUL INCIDENT. TOOK THE VEHICLE IN FOR SERVICE ONLY TO FIND OUT THAT MERCEDES HAS NO ANSWER TO WHY IT IS HAPPENING. ONLY A MATTER OF TIME UNTIL A CLA 250 OWNER GETS KILLED. NO LONGER WILL LET MY WIFE DRIVE THE VEHICLE AND HAVE DEMANDED THAT MERCEDES TAKE IT BACK. VERY DISAPOINTED WITH MERCEDES. *TR
