I purchased a T300 on black Friday last year from Amazon. Received it on Dec. 4, set it up on my rig with the T3PA pro pedals and the 599 Alcantera wheel. Since then I have logged 26 hours on PCars and 12 hours on Assetto Corsa. Two days ago I started up the PS4 with AC and the wheel would not calibrate. It litteraly was frozen. None of the wheel buttons functioned either. The motor became hot and the fan would kick on. Tried PC and had the same result. I am shipping it back to Amazon who are shipping me a new T300 base. After seeing so many faulty units discussed on this forum, and now having that experience myself I really have to question the QC at Thrustmaster. I am willing to give them the benefit of the doubt with the second unit but I am becoming skeptical. I spoke with Thrustmaster and they requested a video and photo of the serial number of the unit which leads me to believe there may have been a run of faulty units.
