GL450 Reliability
We owned one of the first GL450 and it was a great road vehicle. The repair issues were something else, mainly replacing 6 air springs. Would like to know if this has been resolved and any other problems. looking to trade for a 2015 GL450. Thanks for any input.

You are still going to have airbags that fail. If that's the only issues you had with your GL, that's not bad at all.
Check the X166 forum for the 2013+ models.

I owned a 2013 GL-450, absolutely No problems. Bought it new in December 2012. Traded it in Nov 6 2014. Bought a new GL-350 diesel with all the options I wanted. Blind spot detectors, adaptive cruse control, 360 degree cameras, rear entertainment system. 20" wheels, most of the options you can get. Leather, I really like the LED xenon headlight system. Very Quiet, great ride. The new GL-350 rides a little better than the 2013. The new one is not as fast off the line as the GL-450.
