2014 Mercedes-Benz CLA 250 Driver assistance Problems

Apparently the TPS (Throttle Position Sensor) which is built into the gas pedal on this 2014 MB CLA250 only lasts so long before it becomes defective under highway conditions and causes the vehicle to go into LIMP MODE. When full acceleration is necessary, the unit will work for perhaps a few months or less, and then continue to fail worse and more frequently with each attempt at full acceleration. At highway speeds, this is an essential feature in a 4-cylinder vehicle such as this one and without the necessary acceleration capability, can expose the driver to serious risk of collision with other on-coming vehicles traveling at highway speeds. This "Limp Mode" features is extremely dangerous and hazardous to not only the driver of their vehicle, but to other drivers around them since they are left in a devastating position of being unable to accelerate normally and as necessary and as one would expect in any vehicle, let alone a Mercedes Benz. Never before have I driven a car that falls out of full acceleration mode only to subject the driver to serious collision circumstances. Whoever the imbecile is at MB engineering who incorporated this Limp Mode Feature should be fired!!! To make matters worse, this cheaply built TPS, which is the cause of the problem in my vehicle specifically, was only warrantied twice by the dealer and now they will not replace it under warranty which is a two-year period. I've only had the part 5 months before it failed again due to poor manufacturing and I had to pay all over again for a new one despite my warranty validity. There have been many other MB owners who have the same complaint for Limp Mode, which tells me that it's definitely not me, but rather the poorly built or engineered vehicle, as a matter of fact. MB has denied having these complaints to me, which of course, is a lie. That's misleading and deceptive business practices in my State and MB needs to live up to its warranty provisions and respect its customers.

WHEN ACCELERATING HARD TO OVERTAKE, THE ENGINE LURCHES, AND THE CAR FAILS TO ACCELERATE FURTHER AND SLOWS DOWN. THE ENGINE FAULT LIGHT THEN ILLUMINATES WHICH SWITCHED OFF BY ITSELF AFTER SWITCHING THE ENGINE OFF TWICE. IT SEEMS I AM NOT THE ONLY PERSON TO HAVE THIS PROBLEM AS YOU CAN SEE IN THE COMMENTS TO THIS VIDEO DESCRIBING THE PROBLEM AND CLAIMING THE PROBLEM IS A FAULTY HIGH PRESSURE FUEL PUMP: HTTPS://YOUTU.BE/-SBR28ZBOFS THIS SEEMINGLY COMMON ISSUE IS CLEARLY DANGEROUS AS DRIVERS LOSE THE POWER WHEN THEY ARE MOST DEPENDING ON IT AND IT SEEMS TO BE OCCURRING IN CARS THAT ARE NOT PARTICULARLY OLD.

INOPERATIVE PRE SAFE FUCNTIONS LIMITED. VEHICLE LOSES POWER AND BECOMES INOPERATIVE WITHOUT ANY ISSUE. THIS HAS HAPPENED MULTIPLE TIMES WHEN THE VEHICLE WAS IN MOTION. IT IS A POTENTIAL ACCIDENT RISK OF GETTING REAR ENDED. THE VEHICLE LOSES POWER AS SOON AS THE MESSAGE APPEARS AND DOES NOT GIVE ENOUGH TIME TO PULL OVER ESPECIALLY WHEN GOING ON HIGHWAY WITH LOTS OF CARS AND HARDLY ANY GAP TO PULL OVER SHOULDER. THIS HAS HAPPENED ON A CLEAR STRAIGHT ROAD AND ON HIGHWAYS AT 55-60 MILES AN HOUR. I AM SUBMITTING THE DATE OF LATEST OCCURRENCE OF THE INCIDENT IN THIS REPORT.

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.

YESTERDAY I WAS TRAVELLING BACK HOME FROM OFFICE IN THE EVENING ON HIGHWAY, AND SUDDENLY MY CLA250 STARTED SHOWING MESSAGE ON CONSOLE SAYING "PRE SAFE FEATURES LIMITED - SEE OPERATORS MANUAL' AND "VEHICLE INOPERATIVE - SEE OPERATORS MANUAL" AND LOST ITS THROTTLE, I WAS UNABLE TO ACCELERATE, FROM 50MPH I CAME DOWN TO 20MPH WITHIN SECONDS AND IT WAS VERY SCARY AS THERE WERE VEHICLES BEHIND ME THINKING WHAT I WAS UPTO. I IMMEDIATELY SWITCHED ON FLASHERS AND TRIED MY BEST TO PULL IT BACK TO SMALL SPACE BETWEEN DIVIDER AND EXIT, THERE WAS NO PROPER SHOULDER SPACE SO GOT SOME SCRATCHES ON MY CAR. I HAD PURCHASED THIS CAR FROM DEALER AS CERTIFIED PREOWNED VEHICLE JUST TWO MONTHS AGO, AND THIS WAS FIRST TIME I WAS IN SUCH PATHETIC SITUATION. I CALLED ROADSIDE ASSISTANT AND THEY WERE READY TO SEND TOWING TRUCK, MEANWHILE I TURNED OFF THE ENGINE AND RESTARTED IT AND ALL THE MESSAGES DISAPPEARED AND EVERYTHING LOOKED OKAY. I MADE A DECISION TO GO BACK HOME, AS IF MY CAR WERE TO BE TOWED LATE IN THE EVENING , I WOULDN'T GET CAR BACK THE SAME DAY,AND SERVICE CENTER IS LIKE 30 MILES AWAY AND THERE IS NOBODY TO DROP ME BACK HOME. SO I DECIDED TO TAKE IT HOME AND CANCEL TOWING TRUCK CALL. CAR MOVED FINE FROM THEN ON. TODAY I CAME TO OFFICE IN CAR FEARING WHEN IT WOULD STOP AGAIN. I CALLED THE DEALERSHIP AND WHAT THEY SAID WAS "OH DON'T WORRY, THAT MUST BE SOME SOFTWARE GLITCH ON PRE SAFE CONDITION, IF IT HAPPENS AGAIN BRING IT TO DEALERSHIP!!" . SO LITERALLY I NEED TO PUT MY LIFE AND OTHER DRIVERS LIFE AT RISK TO WAIT AND SEE IF IT HAPPENS AGAIN. I LIKE MY CAR, BUT DEFINITELY I DON'T WANT TO DIE IN IT, NEITHER I WANT TO HURT SOMEONE ELSE DUE TO THIS SO CALLED SOFTWARE GLITCH

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.

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.

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).
