The GLE is the same as the ML, they only changed the letters and a few typical slight improvements seen every new model year change. The new chassis will likely come out for 2019 at the end of this product life cycle.
Serta, I'm sorry to hear about your troubles. It does not seem normal to go through such unreliability. Hopefully things work out for you.
