2014 Mercedes-Benz CLA 250 complaints

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.

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

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 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).

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).

WHAT IS THE PROBLEM-PRE SAFE MALFUNCTION ERROR WHEN DOES IT HAPPEN-WHILE DRIVING IS IT PREDICTABLE-NO IS IT SAFE-NO WHY-THE CAR SUDDENLY LOSES ACCELERATION ,WHEN THE PRE-SAFE ERROR COMES ON. SCENARIO-DRIVING A CLA 250 AT 60 MPH ON A MOTORWAY ON A QUIET ROAD IN FRONT OF A TRUCK.... PRE-SAFE MALFUNCTION KICKS IN THE CAR SLOWS DOWN AND LOSES ACCLN. THE TRUCK DRIVER CANNOT PREDICT THIS BEHAVIOR A THIS IS NOT A NORMAL PATTERN TO SLOW DOWN SUDDENLY FROM 60MPH ON A QUIET FREEWAY. VERY VERY DANGEROUS.

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.

TL* THE CONTACT OWNS A 2014 MERCEDES BENZ CLA250. WHILE DRIVING AT APPROXIMATELY 65 MPH, THE VEHICLE STALLED AND THE ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT WAS ABLE TO RESTART THE VEHICLE ON THE FIRST ATTEMPT. THE FAILURE RECURRED INTERMITTENTLY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 25,000.

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.

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.

I WAS DRIVING ON I-85 AT 70 MILES PER HOUR. THE CAR STOP ACCELERATING AND ON THE DASH BOARD A MESSAGE OF INOPERATIVE, SEE MANUAL. I WAS ALMOST HIT BY MANY CARS. I COASTED TO THE SIDE OF THE INTERSTATE. I ALMOST FREAKED OUT. I CALLED THE MERCEDES DEALER AND I WAS TOLD TO CUT THE CAR OFF AND TURN IT BACK ON. THAT DIDN'T WORK. I HAD THE CAR TOWED TO THE DEALER. THE DEALER TOLD ME THEY DID SOME UPDATES AND FIXED THE CAR. THE CAR DID THE SAME THING 2 OTHER TIMES. I COULD HAVE BEEN KILLED IN THE TRAFFIC. THIS TIME I TOOK THAT DEATH TRAP BACK TO THE MERCEDES DEALER AND LEFT IT AND INFORMED THE DEALERSHIP TO GIVE ME ANOTHER CAR OR GIVE ME MY CASH MONEY BACK THAT I PAID FOR THE CAR. I AM NOT TAKING THE CAR BACK. I AM AFRAID I WILL BE KILLED IN THE CAR. THIS IS THE MOST SCARY EXPERIENCE. THE DEALERSHIP TOLD ME THAT THERE IS KNOW FIX FOR THIS PROBLEM THE CAR NEEDS TO BE GROUNDED BEFORE SOMEONE GET KILLED.

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.

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.

THE FACTORY TIRES ON THE MERCEDES BENZ CLA 250 ARE DEFECTIVE. ALL 4 TIRES GOT BUBBLES IN THEM WHICH IS A DANGER TO ANYONE DRIVING AS THE TIRES COULD BLOW AT ANY TIME. THESE BUBBLES ARE NOT OBVIOUS SO I DIDN'T KNOW ABOUT THEM UNTIL I BROUGHT IN FOR SERVICE. LESS THAN A YEAR ALL 4 TIRES HAD ISSUES AND AFTER DOING RESEARCH I HAVE SEEN MULTIPLE POSTS ABOUT THESE TIRES AND BUBBLE ISSUES. GOODYEAR F1RUN FLATS.

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

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

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

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

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

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

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

WAS DRIVING DOWN THE ROAD, THE CAR STARTED HESITATING, AND LURCHING REPEATEDLY. I WAS JUST ABLE TO PULL INTO A PARKING LOT OFF OF THE BUSY STREET THAT I HAD BEEN DRIVING ON. ONCE IN THE PARKING LOT THE ENGINE TOTALLY DIED AND A MESSAGE OF "INOPERABLE" APPEARED ON THE MESSAGE SCREEN. THIS REQUIRED TOWING OF THE CAR TO THE DEALERSHIP. IT WAS DETERMINED THAT THE INTAKE MANIFOLD PRESSURE SENSOR WAS FAULTY AS WELL AS THE CRANKSHAFT POSITION SENSOR WAS FAULTY. ELECTRICAL INVESTIGATION REVEALED THAT A GROUND STUD ON THE CHASSIS WAS PAINTED OVER AND NOT MAKING CONTACT. UPDATE OF SOFTWARE, CLEANING OF CONTACTS, AND REPLACEMENT OF SENSORS RESULTED IN SMOOTH RUNNING ENGINE. *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

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

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

I AM APPROXIMATE ON THE DATE WITHOUT GOING BACK TO SERVICE FILES. THE CAR WAS NEW TO ME AT THE END OF JANUARY 2014. THEN IN MID-MARCH, A COUPLE OF THING WERE HAPPENING. THE CRASH AVOIDANCE ALARM WOULD GO OFF FOR NO APPARENT REASON. THEN, INSIDE OF A COUPLE OF WEEKS THE CAR LOST ALL ABILITY TO ACCELERATE. FIRST TIME I WAS IN THE MIDDLE OF AN INTERSECTION. THE OTHER TWO TIMES, OPEN ROAD, IN EARLY MORNING SO LUCKILY LITTLE TRAFFIC. IN ALL 3 CASES OF THE ACCELERATION LOSS, I WAS ABLE TO COAST TO THE SHOULDER. IT IS NOT AS IF IS A DRIVE TRAIN ISSUE...IF YOU PRESS ON THE GAS AS YOU ARE COASTING, THE ENGINE IS JUST IDLE. DOES NOT REV. ONCE STOPPED COMPLETELY AND RESTARTED, EVERYTHING WAS FINE. THE DASH WARNINGS THAT CAME UP WERE "INOPERATIVE. SEE OWNER'S MANUAL" (NO LIE?!) AND THEN "PRESAFE FUNCTIONS LIMITED. SEE OWNERS MANUAL." CONDITIONS WERE CLEAR IN ALL CASES. SPEED AT THE TIME OF INCIDENTS, ONCE 15 MPH, TWICE AROUND 40 MPH. I TOOK THE CAR TO THE DEALERSHIP. THEY HAD FOR 2+ WEEKS AND THE ISSUE WOULD NOT REPLICATE ITSELF. WHEN I PICKED UP, I WAS TOLD THERE WAS AN "UPDATE" THAT WAS DONE AND MAYBE THAT WOULD PREVENT IT FROM HAPPENING AGAIN. IT DID . . .UNTIL TWO WEEKS AGO. FAST FORWARD TO JANUARY 2015. THE SAME THING HAS OCCURRED 3 TIMES IN TWO WEEKS. TWO TIMES INSIDE OF 15 MINUTES IN ONE CASE. ONCE IN A VERY RISKY MERGING TRAFFIC SITUATION. I AM WRITING THIS ON THE DAY THAT THE LAST TWO INCIDENTS TOOK PLACE. TAKING THE CAR IN TONIGHT. I REALLY DON'T WANT THE CAR BACK UNTIL I KNOW

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

THE ACCELERATOR FAILED TO RESPOND. THE CONTACT HAD TO MANEUVER TO THE SIDE OF THE ROAD AND AFTER APPROXIMATELY 10 MINUTES THE VEHICLE RESTARTED NORMALLY. THE VEHICLE WAS TAKEN TO THE DEALER.

THE APPROXIMATE FAILURE MILEAGE WAS 13,334.

PURCHASE MY 2014 CLA 250 IN JANUARY 2014 FOR MY DAUGHTER. IN MAY MY DAUGHTER CALL AND SAID THE CAR JUST STOPPED RUNNING WHILE SHE WAS DRIVING IT. DIDN'T REALLY THINK ANYTHING OF IT BECAUSE SHE WAS A NEW DRIVER. ABOUT 3 WEEKS LATER SHE SAID IT DID THE SAME THING. AGAIN IN OCTOBER 2014 I WAS DRIVING THE CAR. DRIVING ABOUT 40MPH AND THE CAR JUST STOP MOVING. A MESSAGE OF INOPERATIVE CAME THE SCREEN. I WAS ABLE TO PULL TO THE SIDE OF THE ROAD. THE STEERING WAS VERY HARD TO TURN AND NOTHING WOULD WORK EXCEPT FOR THE BRAKES. IF YOU TURN THE CAR OFF AND START IT AGAIN THE CAR WILL START WORKING AGAIN. PUT THE CAR INTO THE SHOP. THEY SAID IT WAS A COMPUTER UPDATE. MERCEDES DEALER UPDATED THE SYSTEM. AS THEY WERE DRIVING THE CAR BACK TO ME THE SAME THING HAPPENED. SO THEY TOOK IT BACK TO THE DEALER KEPT IF A WEEK AND SAID THEY FIXED THE PROBLEM. THREE MONTHS LATER EXACTLY 1 YEAR HAVING THE CAR. MY DAUGHTER WAS DRIVING TO SCHOOL AND IT STOP RUNNING AGAIN AND THIS TIME THE TIRE LIGHTS CAME ON. SO I PICKED THE CAR UP FROM SCHOOL AND ON THE WAY HOME THE CAR STOP RUNNING AGAIN RECEIVED THE SAME MESSAGE AS ALWAYS THE CAR IS INOPERATIVE. THIS HAS HAPPENED IN ONE YEAR OF OWNING THE CAR 6 TIMES. THIS IS VERY DANGEROUS. I DO NOT ADVISE ANYONE TO PURCHASE THIS CAR. *TR

RECEIVED THE CAR NEW IN NOVEMBER 2013 AND IMMEDIATELY REPORTED THAT THE DRIVERS SIDE VIEW MIRROR WOULD NOT ADJUST TO THE LEFT ENOUGH TO ADEQUATELY SEE VEHICLES IN THE LEFT LANE. THE BLIND SPOT WAS THE LARGEST I HAVE EVER SEEN ON ANY VEHICLE THAT I HAVE DRIVEN. IT WOULD ADJUST TO THE RIGHT FAR ENOUGH TO SEE THE FRONT SEATS INSIDE THE CAR BUT WOULD NOT ADJUST ENOUGH TO THE LEFT TO ADEQUATELY SEE THE LEFT LANE NEXT TO THE CAR. THE VIEW WAS OF THE SIDE OF MY CAR AND A LITTLE OF THE LEFT LANE. IN THE FIRST TWO WEEKS OF DRIVING I ALMOST HAD TWO ACCIDENTS WHEN CHANGING LANES ON A HIGHWAY. I NOW HAVE TO COMPLETELY TURN MY HEAD AND LOOK OUT THE BACK SEAT SIDE WINDOW TO SEE IF THERE IS ANOTHER VEHICLE THERE BEFORE CHANGING LANES. THE DEALERSHIP HAS WORKED WITH MERCEDES AND CHANGED THE MIRROR AND THE MIRROR MOTOR TO TRY TO CORRECT THIS BUT IT HAS NOT. THEY TOLD ME IN JUNE THAT MERCEDES WAS ADDRESSING THE ISSUE FOR THE 2015 MODEL AND THAT I WOULD GET A NEW 2015 MIRROR WHEN AVAILABLE. THEY INSTALLED THE NEW 2015 MIRROR IN DECEMBER BUT IT IS EXACTLY THE SAME AS THE 2014 MIRROR. THIS IS A BIG SAFETY ISSUE IN THAT THE VIEW FROM THE SIDE VIEW MIRROR IS NOT MUCH BETTER THEN THE REAR VIEW MIRROR. THERE ARE MANY COMPLAINTS ABOUT THIS ON THE MERCEDES BENZ BLOG. *TR

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

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

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

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

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
