The shifter randomly stops working so I could have the car in reverse and not be able to put it in drive and be stuck in traffic or vice versa. I can have the car and drive and not be able to put it in reverse. I'd be stuck in traffic very dangerous.

2016 Mercedes Benz CLA250 Greenville, SC

ELECTRICAL SYSTEM

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.

ELECTRICAL SYSTEM

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.

2014 Mercedes Benz CLA250 Winsted, CT

ELECTRICAL SYSTEM

As I was driving yesterday afternoon, I heard a noise and normally we don't hear any type of noise or air coming into the car. I decided to open the sunroof to see if there was something wrong with it like if it was stuck open or if something was stuck in it, and the whole sunroof almost flew off the car. I had to pull over as fast as I could into the break down lane and it took me a while to close it and it still seems to be open, I didn't see anything stuck in the guide rails or in the area when closing it. I was very scared for the safety of my children and myself and for the other drivers on the highway. I have made an appointment so the shop and check the car out and run some diagnostics. There are no warning lights or messages prior to the sunroof almost flying off the car.

My sister was driving across town and came across some uneven payment near a construction zone. She hit a small-medium sized pothole and it somehow triggered both the front and rear passenger airbags to deploy. There was no damage significant impact when it happened and no damage to the exterior of the car (tire, wheel, fender). It happened today (Saturday) so it was taken to a local independent repair facility. Will know more Monday. Parts available for inspection upon request, of course.

ELECTRICAL SYSTEM

WHILE DRIVING THE OTHER DAY I OPENED THE SUNROOF WHEN IT SUDDENLY MADE A STRANGE SOUND AND STOPPED. WHEN I TRIED TO CLOSE IT I NOTICED THAT THE LEFT SIDE WAS RAISED BUT THE RIGHT SIDE WAS DOWN. IT MADE A WHIRRING SOUND AND MOVED A LITTLE BUT REFUSED TO CLOSE. WHEN I GOT HOME AND LOOKED AT IT IT LOOKS LIKE THE WINDSCREEN HAS COME LOOSE AND LOOKS LIKE IT WAS PUSHED FORWARD AND BROKEN BY THE LINKAGE THAT MAKES THE ROOF GO UP. IT LOOKS LIKE THE LINKAGE IS BENDING FORWARD WHEN I SUSPECT IT SHOULD BEND BACKWARDS. THIS HAS BEEN HAPPENING SINCE I BOUGHT THE CAR IN 2016. SOMETIMES IT OPENED AND WHILE DRIVING I'M AFRAID IT MIGHT BLOW OUT INTO THE HIGH WAY. CAUSING AN ACCIDENT
