When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2018 Mercedes Benz AMG CLA45
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.

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.
