Moreover, the rear wheels may lock, resulting in a loss of vehicle control and/or transmission oil may leak or vehicle parts may fall onto the road, endangering other road users.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateIn some vehicles, the front cardan shaft can collide with the clamping body and damage it, which could lead to a sudden loss of vehicle…In some vehicles, the front cardan shaft can collide with the clamping body and damage it, which could lead to a sudden loss of vehicle propulsion, locking of the automatic transmission and wheels, increasing the risk of an accident.

EU Safety GateDepending on the tolerances of the latch and lock trap, the rear doors may not be fully closed, although they appear to be closed.As a result, certain driving manoeuvres and road conditions could cause the rear doors to open unexpectedly while driving, increasing the risk of accident. Additionally, if the child safety lock is activated on the rear doors and excessive force is used on the inner door handle to attempt to open them from inside the vehicle, the closing lever of the lock mechanism may become deformed and prevent the rear doors from being opened from the inside, increasing the risk of injury in the event of an accident.

EU Safety GateThe elastomer material of the oil feed line for the exhaust-gas turbocharger may not comply with the specification, allowing oil to leak…The elastomer material of the oil feed line for the exhaust-gas turbocharger may not comply with the specification, allowing oil to leak out.Consequently, the leaking oil could come into contact with hot components, increasing the risk of fire.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateAn incorrectly embossed lock symbol for the child safety locks may lead to misinterpretations.This could result in the rear doors being opened from inside despite apparently being locked, increasing the risk of an accident.

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…
Windshield cracked on its own with no motive
This is the second windshield that has cracked from a very minor FOD. Most times if a windshield gets a rock chip it's small repairable damage. Both times this windshield has been stuck by a rock it has cracked from top to bottom...no signs of an actual chip from a rock. After searching the internet I came across several situations with the very similar results. The windshield is a concern at the moment and the safety of it is sub standard.

To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
