ELECTRICAL SYSTEM

2 complaints

Rear camera works, but the hatch will not close making it difficult to open and close the trunk. I have seen many vehicles in this Family Class with the rear camera in the same condition which leads me to believe that it's not a maintenance issue.

I SIGNED A LEASE AGREEMENT WITH A MERCEDES-BENZ DEALER ON A 2020 CLA 250 4MATIC CAR. HOWEVER, DUE TO A PENDING RECALL, THE DEALER CANNOT DELIVER THE CAR TO ME (AFTER A WEEK OF SIGNING THE LEASE CONTRACT) BECAUSE MERCEDES-BENZ USA INSTRUCTS THEM TO HOLD THE CAR BEFORE THE RECALL ISSUE IS FIXED. I SEARCHED ON NHTSA.GOV, THE RECALL "MBUSA CAMPAIGN NUMBER 2020010007 NHTSA RECALL NUMBER 20V045" WAS REPORTED ON JAN 27, 2020, WHILE STILL "RECALL INCOMPLETE, REMEDY NOT YET AVAILABLE" ON FEB 28, 2020. I ASK NHTSA TO ACT, AND URGE MERCEDES-BENZ USA TO EITHER RELEASE A RECALL FIX ASAP OR LET THE DEALER DELIVER THE VEHICLE TO CUSTOMER. THEN, A CUSTOMER CAN VISIT A DEALER FOR A RECALL FIX WHEN THE RECALL REMEDY IS ACTUALLY AVAILABLE.

During the manufacturing process, particles was trapped between the fuel and rail injectors, which is causing a fuel leak. A fuel leak in the presence of an ignition source, such as hot engine or exhaust components, increase the risk of a fire.

STEERING,SUSPENSION,UNKNOWN OR OTHER

1 complaint

On 4/27 I was driving home on the freeway and there were little to no cars around me. There were no large trucks or debris coming from above me and there was no harsh weather. I heard a loud pop when i was driving and I pulled over and my whole sunroof shattered. The sunroof also has not been opened that day. The problem won’t be suspension is that when going over rough roads or bumps, my car squeaks. As for the steering, when I drive above 50 MPH and I brake, the car shakes. I’ve already taken it to two car shops to get it fixed and it problem persists.

ENGINE,FUEL/PROPULSION SYSTEM

1 complaint

Approximately several weeks ago, the check engine light illuminated in my vehicle. No issues were present at that time. Shortly after, approximately a week later, the vehicle began to stutter when reversing or driving on surface streets after being on the highway. The vehicle also would stall after the check engine light flashed several times. The vehicle would need to be turned off and turned back on to accelerate correctly and not stall. This has not been inspected by the dealer yet, a service appointment has been made. Mercedes recently recalled other models due to a water intrusion issue, but this model was not included, however it is exhibiting nearly the exact same symptoms.

STEERING,AIR BAGS,FORWARD COLLISION AVOIDANCE

1 complaint

The system that appeared to malfunction is the front airbags sensors. I drove past an accident on the freeway the left by some rocks/debris in the road. I steered away from the rocks avoiding my tires, however, both of my front airbags deploy as if i collided with something. This has completely disabled my vehicle on the freeway, and shattered my windshield. I had the car towed to a repair shop for further diagnostic, and they confirmed there is no front end impact or collision on my vehicle. There is minor undercarriage scrapping, but it isn't near the airbag sensor. There were no warning lights on my vehicle prior to this, and my vehicle has been in no accidents. What caused my airbags to deploy if there was no impact?

WHEELS

1 complaint

The vehicle experienced a blowout of both tires on the drivers side while driving at high speeds on the highway. The sidewalls of both tires ruptured, causing the driver to lose control of the vehicle and wreck the suspension. This accident occured on March 26, 2022 (pending repair invoice). A similar incident in the same vehicle occured on March 20, 2021 that caused a blowout of both driver's side tires (attached repair invoice) after hitting a minor pothole. An additional two tires were replaced in July 2021 (attached repair invoice) and in January 2022. The high speed blowouts caused the driver to lose control of the vehicle at high speeds and almost caused a multi-car accident. The dealer has not acknowledged that the vehicle has any tire issues in spite of having to replace 5 tires due to blowouts and an additional tire due (done at another vendor) to a sidewall bubble within 14,000 miles of driving. There were no issues with the vehicle at the time of any accident. In fact the dealer had inspected the vehicle and tires the same week of the most recent accident (attached service invoice). It is my impression that the persistent tire issues represent a serious and dangerous problem with this vehicle.
