2016 Mercedes-Benz CLA 250 Problems

The contact owns a 2016 Mercedes-Benz CLA250. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed with a failed thermostat. The contact was informed that the thermostat needed to be replaced. The vehicle was not repaired. The vehicle was driven to the residence. The contact performed an inspection on the vehicle and determined there was a melted hole in the air intake valve. The contact stated that the dealer had not provided information of the condition of the melted air intake valve. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 116,000.

Check engine light with error code P052E. From my research, this is a very common issue with this engine and one that either has been recalled or is planning to be recalled. According to some online forums for Mercedes Benz, Mercedes is being sued over this problem and has issued an extended warranty on certain models because of how common this problem has become. The list of models needs to be expanded to include other models experiencing the same problem.

My mechanic said that he believes there is a recall on a recalled part this was previously repaired per Mercedes notice of safety recall dated April 2018. The recall remedy provided by the manufacturer has failed to permanently fix the safety defect, and the vehicle remains unsafe to drive. "On certain Model Year (“MY”) 2014-2017 B-Class electric, MY 2012-2018 C-Class, MY 2012-2017 E-Class, MY 2014-2018 CLA, MY 2015-2018 GLA, MY 2016-2018 GLC, and MY 2013-2015 GLK-Class vehicles, an electrostatic discharge, when combined with a broken steering column module clock spring and an insufficient grounding of the steering components, could lead to an inadvertent deployment of the driver airbag. An inadvertent driver airbag deployment may cause a risk of injury to the driver and might increase the risk of a crash." Currently my airbag and horn do not work as a result of this defect and Mercedes said there is no current safety recalls, however this is the exact issue that was replaced and fixed before I purchased it. They want to charge me a $300 diagnostic fee, (when my mechanic has already looked at it), I am not wanting to pay the dealership for an issue that is clearly related to the recall issue that was not properly fixed. My car is a safety issue to myself and anyone if I drive it, my horn does not work, so that makes it hard to prevent accidents and my airbag, upon reading further online, could potentially deploy and CAUSE and accident.

My 2016 CLA 250 having multiple electrical and driving issues that are not recalled. I’ve researched online and found most of these issues are common. 1. Dashboard screen and radio console lights turn off completely. USB connection triggers electrical symptoms. Front and Back seat window control (driver) triggers electrical symptoms and sometimes corrects the problems. Trunk opens by itself while parked and/or stopped at red lights. The instrument cluster has times multiple warning lights turn on and stay on. At times the fuel needle drops completely down as if I have no fuel in the car. The instrument cluster lights stay on after I have turned the car off and locked it as if the system is confused. I have more issues but those are a few to name. I also have video and pictures to prove these things happen randomly then the vehicle can go back to operating normally. I’ve taken it to service and all they have done is reset the warnings.

My vehicle is exhibiting the same problem as MB Recall Campaign #2021070010 but my MB Vin is not included in the recall even though my make/model of car is on the list. This MB recall campaign is to replace the front stationary sunroof panel. According to recall,"The panoramic sunroof may not have been bonded correctly to the vehicle. The adhesion of the front panel might partially or fully detach from the vehicle increasing the risk/injury to other road users." This campaign which was updated 9/3/2021 should include ALL vehicles on the recall list that exhibit this issue. I contacted an authorized MB dealer show quoted me $2225.41 for a repair that we know is known DEFECT. PLEASE HELP!

Factory window tint of the back window & the driver/passenger side(s) windows are bubbling and peeling causing visual impairment while operating motor vehicle. Examples of impairment are backing the vehicle and changing lanes & these affected areas are blurry. Panaramic Sunroof does not seal properly when closed. Factory vehicle paint bubbling and peeling causing depreciation of the vehicle.

Blow-by gases are mixed with oil mist and other contaminants that can harm an engine's internal components and contaminate the environment. How does the crankshaft ventilation work- When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft) that pulls gases out of the crankcase. To prevent too much vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. The breather is often located in the oil cap the engine misfires, you may have trouble getting your vehicle up to speed. Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on acc

Got a check engine light at 72,047 miles. Looked up the code at autozone and it is a P052E. After googling this code, discovered this is an EXTREMELY common issue with 2015 & 2016 c and cla class mercedes. (see here https://mbworld.org/forums/c-class-w205/739851-check-engine-code-p052e-2.html). This is a ventilation issue with the Positive Crankcase Ventilation Regulator Valve Performance. This is a VERY expensive fix despite seemingly being a VERY common issue at this mileage for these cars. This seems to be a defective part that Mercedes installed at the factory as no one ever gets this message after having their original valve replaced. Without the fix, this will cause oil to become sludgy and perhaps cause engine to seize or smoke.

Factory window tint of the back window & the driver/passenger side(s) windows are bubbling and peeling causing visual impairment while operating motor vehicle. Examples of impairment are backing the vehicle and changing lanes & these affected areas are blurry. Panaramic Sunroof does not seal properly when closed. Factory vehicle paint bubbling and peeling causing depreciation of the vehicle.

The contact owns a 2016 Mercedes-Benz CLA250. The contact stated that while driving at approximately 55 MPH, there was a loud explosion coming from the vehicle. The contact later pulled over, and upon inspection, discovered that the sunroof glass had shattered. The contact stated that there was no impact to the sunroof that could have caused the sunroof glass to shatter. The vehicle was taken to an auto glass retailer, who installed a plastic cover over the sunroof; however, the sunroof glass was not replaced. The manufacturer was made aware of the failure. The failure mileage was approximately 125,000.

AUTOMATIC ENGAGING OF EMERGENCY BREAK WHILE DRIVING OR STATIONARY TOGETHER WITH SIGNALS OF COLLISION PREVENTION ASSISTANT PLUS INOPERATIVE AND TWO OTHER ERRORS (IN PICTURES). CAR WAS BOUGHT RECENTLY BOUGHT AND DELIVERED TO ME ON JANUARY 1ST , 2020. IT HAS BEEN TAKEN BACK TO DEALER TWICE FOR SAME ERRORS. IT WAS REPLACED THE BATTERY TWICE AS DEALER INDICATED IT HAD TO DO WITH AUXILIARY BATTERY MALFUNCTIONING WHICH WAS ALSO ANOTHER ERROR SHOWING IN THE PANEL.

WHILE MERGING ONTO THE FREEWAY ON 1/22/2021 THE CAR'S DASHBOARD DISPLAYED "COLLISION PREVENTION ASSIST PLUS INOPERATIVE " AND THE CHECK ENGINE LIGHT COME ON. WHEN THIS HAPPENED, IT PREVENTED ME FROM ACCELERATING THE CAR BY PUSHING ONTO THE GAS PEDAL. THIS CAUSED THE CAR FROM BEHIND TO ALMOST REAR ENDED BY CAR. I WAS ABLE TO DRIVE ONTO THE SHOULDER OF THE FREEWAY AND EXIT THE FREEWAY. I HAVE TAKEN THIS CAR TO THE MERCEDES DEALERSHIP FOR REPAIR BUT IT IS AN ONGOING ISSUE EVEN AFTER VARIOUS PARTS HAVE BEEN REPLACED.

I LEASED THIS VEHICLE END OF SEPTEMBER 2016 BUT HAVE REPLACED TIRES 6 TIMES WITHIN LAST TWO YEARS DUE TO BUBBLE IN SIDE OF THE TIRES. I DON'T THINK IT IS ISSUE WITH TIRES SINCE I HAVE 2016 BMW WITH SAME TIRES WITHOUT ANY ISSUES. IT COULD THE RIM SIZE OR THE SUSPENSION ON THIS VEHICLE CAUSE TIRES TO BUBBLE UP. I HAVE BEEN LEASING CARS FOR 30 YEARS AND NEVER HAD ISSUES LIKE THIS. NUMEROUS TIME I HAVE ASKED THE DEALER TO FIND OUT THE ROOT CAUSE FOR IT BUT NO LUCK SO FAR. THE ISSUE HERE IS IT PUTTING MYSELF AND MY FAMILY DANGER OF OUR LIFE BECAUSE IT IS HAPPENING WITHOUT EVEN GOING THRU A POT HOLE.EACH TIME WHEN IT HAPPENED, IT IS CAUSING ME TO SPEND 350 TO REPLACE EACH TIRE. THE TRANSMISSION ALSO FAILED LAST WEEK WHILE I WAS DRIVING ON A HIGHWAY BUT LUCKY I WAS ABLE TO PULL TO A SIDE WITHOUT GETTING HIT BY ANOTHER CAR.THE TRANSMISSION SHOULD NOT FAIL WHEN THE CAR ONLY HAVE 37,000.00 MILES. I AM NOT SURE IF ANY OTHER COMPLAINS WAS FILES REGARDING THE SAME ISSUES. I WANT BENZ TO REPLACE THESE TIRES AT FREE OF COST TILL THEY FIND OUT THE ISSUE AND FIX IT.

THE TIRES BLEW OUT ON THE NJ TURNPIKE WHILE DRIVING APPROXIMATELY 67 MILES PER HOUR. THEY ARE PIRELLI CINTURATO P7 RUN FLAT 225 40R18. ONE OF THE OTHER TIRES HAS A BUBBLE IN IT. THE VEHICLES LOST CONTROL AND WAS SWERVING SEVERELY RIGHT AND LEFT ALMOST DOING A FULL 180 DEGREE TURN IN THE MIDDLE OF THE HIGHWAY WHICH NEARLY HIT OTHER VEHICLES DRIVING OVER 65 MILES PER HOUR. VEHICLE IS 2 YEARS OLD AND HAD TIRE ISSUES AT LEAST 4 TIMES PRIOR TO THIS INCIDENT. TIRE HAD PRESSURE ISSUE AND WAS TAKEN FOR SERVICE TO MERCEDES OF CHERRY HILL NJ APPROXIMATELY A MONTH BEFORE THIS BLOW OUT.

There appears to have been a malfunction with the seat warmer that resulted in a fire.

The right passenger seat belt is faulty.
