My 2017 G550 misfired on a highway and I had total failure with kids in the backseat creating an immediate life-safety hazard. This issue was caused by the M176 engine, which is known to create misfires. Mercedes tried to blame it on me not changing my spark plus, but I showed proof they were changed with a certified Mercedes mechanic. G wagons with that engine should 100% be recalled. They make the vehicle extremely unsafe to drive as it can happen at anytime with ZERO warning. Mercedes still has my vehicle 1 month later and it's not safe to drive.
