There are 4 owner-reported electrical system complaints for the 2015 Mercedes-Benz E-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Went on a 2000 miles road trip and my blind spot monitoring systems and then my turn signals stopped working.
THE COLLISION PREVENTION ASSIST MODULE WARNING LIGHT CAME ON. COLLISION ASSIST WAS INOPERATIVE. THIS CAN LEAD TO LOSS OF ACCELERATION AND BRAKING. I TOOK THE VEHICLE TO LOCAL DEALERSHIP, MERCEDES BENZ OF ARCADIA, WHO PERFORMED A SOFTWARE UPDATE AND CHARGED $205.OO. THIS IS A SAFETY ISSUE AND SHOULD BE A RECALL AND FREE OF CHARGE. WHEN THE ERROR MESSAGE CAME ON MY WIFE WAS ON THE FREEWAY. SHE PANICKED AND PULLED OVER TO THE SHOULDER. RESTARTING THE ENGINE DID NOT SOLVE THE PROBLEM. SHE DROVE HOME SLOWLY WHEREUPON WE WENT TO THE DEALERSHIP.
TAKATA RECALL #17V627, I WAS NOTIFIED OF THE RECALL BUT UNABLE TO GET THE DEFECTIVE PARTS REPLACED AS THE DEALER REPORTED THAT REPLACEMENT PARTS ARE STILL NOT AVAILABLE.
TL* THE CONTACT OWNS A 2015 MERCEDES BENZ E400. WHILE DRIVING APPROXIMATELY 40 MPH, THE VEHICLE WAS EQUIPPED WITH A DISTRONIC DEVICE THAT ALLOWED THE CONTACT TO STOP THE VEHICLE IN THE EVENT OF A CRASH. THE CONTACT STATED THAT THE DEVICE FAILED AND CAUSED THE CONTACT TO CRASH INTO THE REAR OF ANOTHER VEHICLE. THE AIR BAGS DID NOT DEPLOY. A POLICE REPORT WAS FILED. THE CONTACT AND THE PASSENGER SUSTAINED MINOR INJURIES, WHICH REQUIRED THE CONTACT TO SEEK MEDICAL ATTENTION. THE VEHICLE WAS TOWED TO A TOW LOT AND THEN TO A DEALER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 1,500.
