When attempting to rise/lower the automatic suspension, the compressor cooling notification pops up, followed by a malfunction. After this occurs, the vehicle is incredibly bumpy, to the point of it being unsafe to drive. The vehicle has been repaired twice already by the dealership under extended warranty and the condition has occurred a third time in less than three weeks. This is our family vehicle, and we cannot drive it due to the risk of shaken baby syndrome for our infant because of how much it bumps. Videos are available to show just how bad it is.

I TOOK THE CAR TO THE SERVICE 3 TIMES IN 4 MONTHS. THERE ARE MANY PROBLEMS WITH THE CAR. THE FIRST PROBLEM WAS THAT THE LEFT REAR SHOCK WAS LEAKING WHICH MADE A SQUEAKING NOISE WHEN DRIVING. THERE WAS ALSO AN ODOR PROBLEM WITH THE CAR THAT WAS COMING FROM THE VENTILATIONS. THESE TWO PROBLEMS WERE FIXED. I TOOK THE CAR ANOTHER TIME. THERE WAS ANOTHER PROBLEM WITH THE ECO START/STOP FUNCTION AND A PROBLEM WITH THE CAR TRUNK ONLY CLOSING HALFWAY. THE ECO START/STOP FUNCTION WAS FIXED BUT THEY SAID THAT THEY DIDN'T DETECT A PROBLEM WITH THE TRUNK. THE THIRD TIME I TOOK IT TO THE SERVICE I PROVIDED A VIDEO FOR THE TRUNK ONLY CLOSING HALFWAY AND I ALSO HAD ANOTHER PROBLEM WITH THE BLINDSPOT DETECTOR. MY WIFE WAS ALMOST GONG TO GET INTO AN ACCIDENT AS A RESULT OF THE BLIND SPOT NOT SHOWING UP WHEN SHE WAS MOVING TO THE LEFT LANE. I TOOK A VIDEO OF THE BLIND SPOT DETECTOR NOT WORKING PROPERLY. THEY WERE ABLE TO FIX THE CAR TRUNK AND SAID THAT THE BLIND SPOT DETECTOR WAS FIXED, BUT I HAVE NO FAITH IN THE COMPANY BECAUSE I HAVE HAD MANY PROBLEMS WITH THE CAR. THIS IS A NEW CAR THAT WAS MADE IN 2018, AND IT ALREADY HAS HAD MANY PROBLEMS WITH IT IN THE PAST MONTHS. WE CALLED THE MERCEDES MANUFACTURER IN THE US ABOUT THESE PROBLEMS. THEY SAID THAT THEY WILL GET BACK TO ME BUT HAVE NOT SAID ANYTHING. I TRIED CALLING THEM BACK BUT THEY WOULDN'T ANSWER ME. WE TOOK THE CAR FROM A MERCEDES CAR DEALERSHIP. THE ATTACHMENTS ARE COPIES OF THE SUMMARY OF THE THREE SERVICES THAT I WENT TO. THIS IS A NEW CAR AND IT ALREADY HAS THIS MANY PROBLEMS.
