2020 Mercedes Benz GLE 350 other reported problems

UNKNOWN OR OTHER

The a/c unit failed and is available for inspection upon request. Being in an over-heated car can cause dehydration, heat exhaustion and/or heat stroke. I was nauseous and dizzy while driving, putting myself and my passengers at risk. Upon taking my car to a independent service dealer, it was revealed that their is a leak and the evaporator must be replaced. It has not been inspected by a Mercedes dealer yet. No warning messages.

I am submitting a safety complaint regarding my 2020 Mercedes-Benz GLE 350 due to what appears to be a significant air conditioning refrigerant leak. The vehicle rapidly loses refrigerant shortly after being recharged. When the system is operating, a loud seeping/hissing sound can be heard from the HVAC system area, followed by complete loss of cold air within a very short period of time. This issue appears to indicate a major refrigerant system failure and raises concerns about potential defects in the evaporator, condenser, hoses, or related AC components. The leak rate is excessive and ongoing. I am concerned this may be a broader manufacturing defect impacting other Mercedes GLE vehicles. The vehicle has been properly maintained, and the failure occurred under normal operating conditions. Given the frequency of similar complaints online involving Mercedes HVAC refrigerant leaks and evaporator failures, I believe this issue warrants investigation for a potential recall or manufacturer accountability. The failure impacts driver and passenger comfort and visibility in humid or high-temperature conditions due to inability to properly defog windows. I respectfully request that NHTSA investigate this issue for potential safety and defect trends affecting the 2020 Mercedes-Benz GLE platform.

My car shook while idling the last two weeks of June 2025. It felt like it was going to shut off at light/stop sign which it did on two occasions. On July 2, 2025, it stalled abruptly during a drive after which I took it to Mercedes for service. I never received a warning signal or fault message even after it stalled. Mercedes service indicated the engine cylinder head valves were burnt and not sealing properly - estimated cost of repair $10,023.00. I am the original owner of the car, had routine maintenance and only had it performed at Mercedes. My car stopped without warning- but luckily on a local road. Others who are driving with this defective engine may not be so lucky. It appears this is a known issue to Mercedes USA but they have not done anything to fix it. The engine is M264. Even if valves are replaced, this problem may continue to occur as the Mercedes serviceman does not know what caused the burnt cylinders - just that they needed to be replaced and that it was not wear and tear. Not sure if this is related, but there was a 2022 recall on this engine (my car was not part of batch that was recalled) regarding turbo charger oil feed and return lines. The issues included engine vibration at idle and loss of power.

The air conditioner is constantly leaking refrigerant due to a potential damaged hose which is a known issue for Mercedez-Benz SUVs. I contacted the dealership who advised this is not an issue currently being addressed by the manufacturer and would be at the cost of the vehicle owner.

Hear a clicking sound when I drive the vehicle - like a metronome. It happens randomly and I am not able to recreate it when I take the car in for service. I recorded a video of it when it happened and showed it to the dealership service department - They said they hear the sound but cannot do anything about it unless they can hear it when they take it for a test drive. This has been happening for atleast two years now from when the car had 25000 miles to even now when it has 61,000 miles. It does not matter what speed I am driving it. Once it starts it continues till I stop the car and turn it off .
