2019 Mercedes-Benz G 550

The driver-side door latch on my 2019 Mercedes-Benz G550 is malfunctioning. The door fails to securely close or stay latched, even when shut firmly. This poses a serious safety hazard while driving, as the door may open unexpectedly during motion or remain partially ajar. I have not been involved in any accidents, and the vehicle is well maintained. The issue seems mechanical in nature and affects the structural integrity of the door and its latching mechanism. I contacted an authorized Mercedes-Benz service center and was informed there is no recall. I also contacted Mercedes-Benz USA and am awaiting further response. This is a high-end, relatively new vehicle, and a door latch failure of this kind could lead to injury or worse. I am submitting this complaint to ensure this matter is officially recorded and to urge NHTSA to investigate whether this is a wider defect.

MY 2019 G550 HAS BEEN TO MERCEDES DEALERS TWICE FOR A "FRONT/REAR DIFFERENTIAL LOCK SYSTEM MALFUNCTION" ERROR APPEARING ON THE DISPLAY SCREEN. ALONG WITH THIS IT SHOWS THE ABS AND ESP ARE BE INACTIVE. EACH TIME AT A MERCEDES DEALER THEY REPLACE PARTS AND SAY IT IS FIXED. IT IS NOT FIXED. THIS WEEK I BECAME STRANDED WHEN I PICKED MY DOG UP FROM THE VET AND THIS ERROR MESSAGE APPEARED, ALONG WITH 'ACTIVE DISTANCE ASSIST INOPERATIVE', 'ACTIVE BRAKE ASSIST FUNCTIONS LIMITED', 'BLIND SPOT ASSIST INOPERATIVE', 'STEERING MALFUNCTION INCREASED PHYSICAL EFFORT' ERROR MESSAGES. THE CAR COULD NOT BE STEERED. I TRIED TO TRADE IT IN AT A MERCEDES DEALER AND THEY TOLD ME THERE IS A RECALL FOR THIS THAT THERE IS NO REMEDY AVAILABLE FOR, SO THEY CAN'T EVEN TAKE THE CAR IN TRADE. THE RECALL # IS 2020020019. NHTSA RECALL # 20V090. THE MANUFACTURER HAS NO FIX FOR THIS PROBLEM. MERCEDES OF NORTH ORLANDO OFFERED TO LOOK AT IT FOR A THIRD TIME BUT THEY ALSO SAID THERE IS NO FIX FOR THIS RECALL, AND WERE UNABLE TO OFFER ME ANY SOLUTIONS. THE ERROR MESSAGES COME ON AT DIFFERENT TIMES. USUALLY WHEN THE CAR IS STARTED. THIS LAST TIME THE STEERING WAS INACTIVE, I TRIED TO BACK OUT OF MY PARKING SPACE AND COULD NOT TURN THE STEERING WHEEL. IT CAN HAPPEN WHEN THE CAR IS IN MOTION OR STATIONARY. THE DEALERS HAVE REPLACED PARTS FOR THE DIFFERENTIAL BUT IT MAKES NO DIFFERENCE.

Complaint Consistently reproducible erroneous parktronic warnings from front with every key cycle. Cause The parking sensors are detecting the front brush guard. Remedy Complaint must be consistently reproducible and can occur multiple times a key cycle without obvious cause. NOTE: The parking system serves solely as an aid. Please review both the system function and system limitations as shown in the Operator's Manual. Certain environmental factors can affect system functionality such as hot exhaust gases or extreme heat, sensor interference, or other outside influences or aftermarket modifications. If after verifying the complaint is consistently reproducible: 1. Determine if the complaint is reproducible only in high ambient temperatures. If complaint does not occur in cooler ambient temperatures, it is due to system limitations. You may proceed with the below work but the vehicle may be released afterwards as it is due to system limitations. 2. Remove the brush guard and verify the park distance sensors function as expected. 3. Reinstall brush guard and adjust so that it is as far away from the park sensors as possible. This typically means moving the bar further away at the bottom and closer at the top. 4. Check function. If the concern is still consistently reproducible, please apply clear matte film to the locations as shown below at a minimum, although the clear matte film may be applied to the whole brush guard. Picture: Above shown is the 465 brush guard variant. Although similar to the 463, there are some key differences such as the 465 being fitted with a front camera.

Dear Mercedes-Benz Owner: In our continuing efforts to ensure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA is extending the warranty coverage for the Diagnostic Module for Tank Leakage Detection ("DMTL") on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years/150,000 miles (whichever occurs first).

On certain Model Year 2018 - 2024 A / C / CLA / CLS / E / G / GLA / GLB / GLC / GLE / GLS / GT / S / SL Mercedes-Benz vehicles, under certain circumstances, the DMTL may trigger erroneous Diagnostic Trouble Code ("DTC") entries that may result in the illumination of the Check Engine Malfunction Indicator Lamp ("MIL"). Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. • If your preferred authorized Mercedes-Benz dealership performs a diagnosis and confirms that your vehicle has the issue, the repair will be covered under this extended warranty and performed at no cost to you. • This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.

Complaint Clanking noise from the area of the speakers in the doors. Cause Under analysis.
