Hello everybody, pretty new member here. My car is a 2017 srt 392 m6. Got it on the 3rd of July (2017). It has over 6k miles already . I have two problems and I am wondering if anybody can help/relate. My drivers seat is squeeking so bad. Like bad bad. Like every crease, crevis, undulation on the road the seat squeeks. I accelarate it squeeks. I take my foot of the clutch it squeeks. Squeeky squeeky squeeky!!. Its crazy bad. Bad to the point I got so dissapointed that I said ?I should of never got this car!!? I felt sad... Because I love my car. Im crazy about it. In addition I cant drive between 40-55mph. Why? Because the rear end or what ever whines like literally a supercharger. Its annoying because I like those speeds lol. I never realized I drove in between those speeds so often until the sound just made its way into my life. Is it the diff? Tranmission?? I have no idea. The car has no mods. Tires are stock and I never took it to the strip. Anybody else have or has had these issues? Maybe I should change out the transmission and diff fluid? Any help is appriciated guys.
