What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Mercedes-Benz G500, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
I WAS DRIVING ON HIGHWAY ABOUT 50MPH WHEN VEHICLE SUDDENLY WOULD NOT SHIFT GEARS AND WOULD NOT ACCELERATE; ONLY THE ENGINE INCREASED RPMS. I TRIED TO MANUALLY SHIFT GEARS AND NUMBER ON THE INSTRUMENT CHANGES BUT THE TRANSMISSION WOULD NOT RESPOND. I WAS ABLE TO COAST OVER THE THE SHOULDER PLACED THE CAR IN PARK, SHUT OFF THE IGNITION AND RESTARTED THE CAR.NOW ALL WAS NORMAL. THEN A FEW WEEKS LATER THE SAME THING HAPPENED CAR WAS UNRESPONSIVE IN CHANGING GEARS IN AUTO MODE OR MANUAL MODE. AGAIN STOPPING AND RESTARTING CAR IT ACED NORMAL. FINALLY THIS PAST DAY IT HAPPENED WHEN MAKING A RIGHT TURN I COMPLETELY LOST THE ABILITY TO MOVE THE VEHICLE IN AN INTERSECTION AND WAS ALMOST REAR ENDED. I HAVE MAINTAINED THIS UNIT ACCORDING TO THE MANUFACTURER SERVICE SCHEDULE AND IT WAS LOOKED AT BY THE DEALER IN SEPTEMBER OF 2014. THIS ISSUES OCCURS WITHOUT WARNING AND WITH NO ALERTS FROM THE VEHICLE THAT IT IS OCCURRING. THIS IS A VERY DANGEROUS FLAW WITH THIS MERCEDES BENZ 722.9 GEAR BOX. A QUICK SEARCH OF THE INTERNET REVEALS THAT OTHERS IN THE USA AND AROUND THE WORLD HAVE EXPIRENCED SIMILAR UNSAFE OPERATION OF THIS GEARBOX AND MERCEDES HAS DONE NOTHING ABOUT IT. I AM WORRIED THAT I COULD LOOSE POWER SUDDENLY AGAIN WHEN NEED IT MOST AND POTENTIALLY INJURE MYSELF, MY PASSENGERS OR OTHERS ON THE ROAD.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
