Regarding 2018 CLA 45 AMG: On 9-21-21, while I was driving approximately 45 MPH on a 4 lane road, suddenly the car completely shut down. A message simultaneously popped up that the car was disabled and instructed me to look up in manual. Immediately I turned right into the first driveway where the car came to a stop. I was able to restart car and drive home. At that point, the car's total mileage was 17,189. 10-7-21: Deeming the car unsafe to drive, I had the car towed to Mercedes-Benz of Raleigh for a pre-arranged appointment on 10-8-21with service advisor Christopher Moore. After the tech ran numerous tests, he found the ME control unit was faulty and replaced it at no charge. Since I drove it back home, I haven't driven it since.

Manufacturer has not fixed the outstanding software safety recall in a timely fashion. I have contacted them over 10 times and no one has any idea when the software update will be sent and there is no one they can escalate the issue to. I use the car for work, but I am not allowed to use a car with an outstanding safety recall.
WE WERE ADVISED MERCEDES-BENZ IS ISSUING A RECALL DUE TO MOLD EXISTING IN THE FACTORY HVAC SYSTEM FROM A LAW FIRM MAILER. WHEN CONTACTING MERCEDES-BENZ, THEY STATED THEY ARE OF THE PROBLEM AND TOLD US A RECALL WOULD BE TAKING PLACE AROUND JANUARY 2021. WE BOUGHT THIS VEHICLE NEW IN OCTOBER 2018 AND INGEST POSSIBLE MOLD SPORES DAILY WHILE ENDURING A HORRIBLE MUSTY SMELL. WE ATTEMPTED TO TRADE IN OUR VEHICLE FOR A NEWER MODEL AND WERE INSULTED WITH THE SALES MANAGER'S RESULTS AT ZT MOTORS, FORT WALTON BEACH, FL. SO, NOW WE ARE STUCK WITH A $70,000 VEHICLE, PAYING MONTHLY PAYMENTS, AND NOT BEING INFORMED DIRECTLY BY MERCEDES WHEN THIS CORRECTION WILL TAKE PLACE. I HAVE AN AUTOIMMUNE DISORDER AND BEING AROUND MOLD IS EXTREMELY DANGEROUS FOR ME. VERY DISGUSTED BY MERCEDES-BENZ AND WILL NEVER PURCHASE ANOTHER AS THEY DO NOT TAKE CARE OF THEIR LOYAL CUSTOMERS.
