Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2020 G 550 is unknown or other with 1 filings, followed by engine (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 5 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 15 investigation files overlapping the 2020 G 550. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

On this vehicle the oil pump-oil control valve has malfunctioned. The vehicle has 54000 miles on it and the repair costs $8500. The part is only $300 but the transmission must be removed to repair the vehicle. The safety of people is not compromised by the part. The malfunction has been confirmed by the dealer. The malfunction has been reported to mercedes, the warranty company also. The check engine light came on and notified us there was a problem.
I HAVE A BRAND-NEW VEHICLE THAT WENT INTO A SERIOUS SAFETY RECALL IN FEBRUARY. SINCE BEING NOTIFIED IN EARLY MARCH, THE MANUFACTURER CONTINUES TO SUGGEST THERE IS NOTHING THEY CAN DO TO REMEDY THE SITUATION (NO PARTS AVAILABLE), AND IT IS NOW MAY. WHAT IS MORE CONCERNING IS I AM BEING TOLD TO CONTINUE TO DRIVE THE VEHICLE IF THERE ARE NO SIGNS OF DEFECT (AS IF I AM AN EXPERT). MBUSA KEEPS REFERRING ME BACK TO THE NEW VEHICLE WARRANTY THEY ARE 'HONORING'. UNFORTUNATELY, I DO NOT CARE WHAT IS OUTLINED IN 100 PAGES OF A LEGALLY WRITTEN WARRANTY DOCUMENT. IT IS IMPLIED WHEN A PERSON PURCHASES A NEW VEHICLE, THAT IT WILL NOT GO INTO A MAJOR SAFETY RECALL FOR TWO MONTHS. WHAT I CAN'T SEEM TO UNDERSTAND IS HOW MBUSA IS COMFORTABLE TELLING ME TO CONTINUE TO KEEP DRIVING A DEFECTIVE VEHICLE, KNOWING I HAVE A ONE YEAR OLD IN THE BACKSEAT. SHOULD I ASSUME THE RECALL IS NOT THAT SERIOUS? MBUSA NEEDS TO STEP UP AND DO THE RIGHT THING. THANK YOU, [XXX] INFORMATION REDACTED PURSUA
