What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Mercedes-Benz AMG GT53, 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
Was traveling to Ft. Worth to babysit my grandchildren and when I was on the freeway in afternoon traffic my car was not accelerating and I kept stepping on the gas and the car started to get slower and then all of a sudden it completely stopped in the middle of traffic(I didn't pull over to the side like Mercedes stated, it stopped in the middle lane of the freeway, the engine light was on) and I had to locate the hazard lights so no one would run into the back of my car. When it stopped, I had to put it in park and restart the car. I thank God that my grandchildren weren't with me or that someone didn't hit the back of the car. I ask Siri to find the nearest dealership and it was Mercedes-Benz of Grapevine, proceeded to go there first. They called me the next morning and told me it was the Fuel Pump. Then on Jan. 16, 2026, I took my car in for routine maintenance and they found a leak on the Front Differential and they practically removed the whole engine to fix the leak. Had this fix on Jan 20, 2026 This car just turn 2 years old on Dec. 23. Contacted the corporate office as I was directed by the Service Director, Richey Barnes and was told that before they could do anything it had to break down again or anything major. I told them that I have my young grandchildren with me since I often have to babysit them and he told me that there was nothing he could do.

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.
