Hey guys, I have a 2015 CLS63 AMG and I have noticed a grinding, squeaky sound coming from the front of the car during low speeds. It happens a lot in stop and go traffic. Also, whenever I accelerate from a stop sign you can hear that grinding sound. The sound only occurs when you press the gas pedal to accelerate. It never happens while pressing the brakes. This only happens when the car is full warmed up. The sound only happens between 0-10 mph during slow acceleration or at low speeds. After about 10 mph, the sound goes away when you hit higher speeds. I thought the grinding sound gets worse when the A/C is on but you hear the grinding, squeaky sound when the A/C is both off and on. I searched around but couldn't really find anything. I've also heard some E63 AMG guys are having the same problem. Any help would be great! Thanks guys!
