Why Is My 2024 AMG GT 63 S Making a Whining Noise? A Customer’s Story

A Boca Raton AMG owner reached out to us with an unusual problem on his brand-new 2024 AMG GT 63 S E Performance. The car, which he has owned since new, emits a persistent whining sound, described as a “wooooo”, every time he presses the accelerator. The noise stops immediately when he lifts his foot.

He’s ruled out the audio system, regenerative braking settings, and driving modes, including Electric, Sport, and Sport Plus. The sound remains constant whether the engine is cold or hot.

The owner notes that the whine disappears when the car is coasting or maintaining speed without acceleration. But the moment his foot touches the pedal, the “wooooo” returns. He suspects it’s related to the electric motors, and he’s wondering if this is normal for the hybrid powertrain.

We’ve seen similar cases with high-performance hybrids where the electric motor’s inverter or gear mesh can produce a distinct whine under load. However, it’s worth checking for a potential issue with the electric drive unit or a failing bearing.

Our advice: Bring the car to Boca Auto Care for a professional diagnosis. We’ll perform a road test under controlled conditions, inspect the electric motor and transmission for unusual wear, and compare the sound to known characteristics of the AMG E Performance system. If it’s a normal operating noise, we’ll explain it.

If it’s a defect, we’ll help you get it covered under warranty. Don’t let a mysterious whine ruin your driving experience, let’s get it sorted.
