Common issues include low fluids, burnt out fuses, worn tires, and old brake pads. All of these things are covered in the maintenance schedule that is found in the owner's manual and will be taken care of if You take the car in for regular tune-ups. Beyond these common maintenance issues, it is important to never ignore a check engine light. This light comes on for a number of reasons, but they are always to indicate that something is wrong, or needs looking at. If You do not know what the light is coming on for then You can take the car to a dealer. They will look at the trouble code using an OBD scanner, which will give You more info. As long as You do these things then there should not be any major issues that come in with the car, and what problems do arise can be found and fixed early.

There are not any specific issues with the 2014 mercedes gl550, however due to the age of the vehicle it is likely there will be issues with the engine or transmission. Rust or damaged metal could have set in over time. Likewise the brake lines and other fluid lines should be checked for dry rot and leaks. Brake pads will likely need to be replaced and tires should be checked for age and rot. The oil and oil pump should be checked for rot on the lines, and cracks in the pan. There may also be dead or damaged wires and blown fuse causing electrical problems throughout the vehicle.
