2016 Mercedes Benz CLA250 other reported problems

UNKNOWN OR OTHER

I believe that my vehicle is subject to Recall Campaign # 21V197000. The vehicle is a 2016 Mercedes-Benz CLA250. I've had to have this part ( Front Stationary Roof panel) adhered 5 times in the last 10 months. Mercedes refuses to acknowledge the above campaign #. Not only is this a safety risk to my self and other drivers, there is risk of water damage any electrical components. When this issue was brought to their attention I was told this was VIN specific and no recalls were attached to this vehicle. The photos are from 2 separate incidents. There are no warning lights. My vehicle has had at least 2 unbiased inspections and available upon requet.

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.

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.

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

There is a service recall campaign for my model car but dealer/mercedes usa doesn't have the recall linking my car to it from my VIN. Campaign number is P-RC-2021070010. It is to replace the front stationary sunroof panel because it may not have been bonded correctly and could fly off and hit someone. My vehicle did have this same part rattle in 2017 during a cross-country trip.

Inside the car smells gas either idle or running. Dashboard lights flactuate and sometimes the gas gage doesn't show how much fuel you have left. Command system shuts off after 3 mins even the engine is on. But mainly, the gas smell in the car. Have trouble breathing at times and I don't haveany underlying condition.

P052E: Positive Crankcase Ventilation Regulator Valve Performance. It is available for inspection upon request. It was a problem that was confirmed by two independent service centers. It first appeared at around 30k miles, then the engine light disappeared. At around 40k, it starts to intermittently appears and disappears, most of the time the engine light was off, my mechanics checked at it, said it was not uncommon to see this problem with Mercedes and said it won't affect driving. At around 50k it starts to appear more often, still intermittently. I got a second opinion with another mechanics, was told again that he saw this happening commonly with Mercedes. Crankcase alone cannot be replaced, I'll need to replace the whole thing which part cost 750+, with 1200+ labor at an independent service center, and the local mercedes dealer quote double the price.

I was driving on the street and lost power, I looked down and saw a red transmission message and noticed that my vehicle was in neutral. I hurried, and stepped on the break and put my car in drive. I drove 5 minutes to my destination. A few hours later, as I was leaving my destination, my car did the same thing. I lost power, the red transmission light popped up and my car was in neutral. I noticed it once a few months ago and thought it was minor. As I reflect, I have had a few instances where I was driving and my acceleration was off. I took the streets to the mechanic today and they stated that they could not find anything wrong with the car.

The panoramic sunroof failed to close after it was opened. I attempted to close the sunroof after use and it stayed open. This is concerning as debris could have flown into the car and impaired operation. Another concern is the short-circuiting/fire risk of the internal wiring and components in the event of rain. We took the car to the dealership where an associate told us that this is a common problem with CLA class cars. This was the only inspection of the car thus far. There were no messages or warnings prior to the failure.

My radio completely turned off & the whole colonization system is shut down. I cannot control anything like changing the time or lights in my car & I have no working screen. The screen is completely black & nothing turns on or works. It randomly turned off one day & hasn’t come back on. I took it to the dealership & they want me to pay $2,500 to get it fixed. I did not cause this issue, the car itself caused this. I do not think I should have to pay for something I did not cause.

I PURCHASED THE VEHICLE JANUARY 2019, THE VEHICLE WAS RUNNING SMOOTH FOR A COUPLE MONTHS. NOW IT IS JANUARY 2020 AND BETWEEN THE MONTHS OF SEPTEMBER AND NOW I HAVE BEEN TO MERCEDES ABOUT 4 TIMES. THE CAR DOESN'T REVERSE SOMETIMES WHILE I AM DRIVING. THE WORDS 'CAR CANNOT REVERSE' COMES UP ON THE DASHBOARD. I COULDN'T USE THE HEAT IN NOVEMBER DUE TO A GAS SMELL COMING IN THE CAR. SOMETIMES I WILL BE IN GEAR 3 AND THE CAR WILL CHANGE TO GEAR 5 ON ITS OWN. AS OF RIGHT NOW THERE IS A BURNING SMELL SURROUNDING THE VEHICLE WHEN YOU ARE DONE DRIVING IT.

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 SUNROOF SPONTANEOUSLY EXPLODED WITH A LARGE NOISE RAINING GLASS DOWN ON US. THERE WERE NO CARS AROUND, NO OBJECTS HIT THE SUNROOF. WE WERE DRIVING AT NORMAL SPEED ON THE HIGHWAY. THIS ISSUE IS VERY DANGEROUS BECAUSE IT WAS STARTLING LIKE AN EXPLOSION AND COULD HAVE CAUSED LOSS OF CONTROL. THE CAR HAD VERY LOW MILEAGE WAS PRACTICALLY BRAND NEW IN PERFECT CONDITION.

*** I DON'T OWN THIS CAR. *** MERCEDES SENT THE REMOTE ACCESS CREDENTIALS TO AN UNVERIFIED EMAIL ACCOUNT. THE REMOTE ACCESS APP SHOWS VEHICLE LOCATION, ALLOWING UNLOCK AND VEHICLE START WHICH COULD ALLOW THE VEHICLE TO BE EASILY STOLEN. ALSO I FEAR THAT BY NOT SECURELY SENDING REMOTE ACCESS CREDENTIALS THE REMOTE START FEATURE OF THE APP COULD BE USED TO START THE VEHICLE WHEN IT IS PARKED IN AN ATTACHED GARAGE WHICH COULD INUNDATE THE HOUSE WITH CARBON MONOXIDE. MERCEDES NEEDS TO VERIFY OWNER EMAIL PRIOR TO SENDING VEHICLE ACCESS CREDENTIALS. ADDITIONALLY STEPS SHOULD BE TAKEN TO ENSURE THAT REMOTE START FEATURES CANNOT CAUSE HARM TO OWNERS IN CASE ONLINE ACCOUNTS ARE HACKED SUCH AS THE RECENT YAHOO EMAIL FIASCO: * LIMIT THE AMOUNT OF TIME A VEHICLE CAN BE LEFT RUNNING. * LIMIT THE NUMBER OF TIMES A VEHICLE CAN BE REMOTE STARTED IN A ROW. * ADD A CARBON MONOXIDE DETECTOR TO THE VEHICLE SO IT WILL SHUT ITSELF DOWN IF RUNNING IN AN ENCLOSED SPACE. * REQUIRE 2 FACTOR AUTHENTICATION WHEN LOGGING INTO REMOTE APPS, PERHAPS ONLY THE FIRST TIME?
