I received my 4452 for Christmas last year (2018) and use it almost every day with no issues until recently. I was 3/4 through a project and it simply froze. I cannot move the hand wheel at all! I took it to JoAnn Fabric where it was purchased and was told that it was the motor. This is the first time I have had a Singer die on me when the machine is just under a year old. I was told the motor was under warranty for the motor but not the labor. Very frustrating for a machine that claims to be capable of handling home projects. The last Singer I had stopped picking up stitches and the gentleman repairing it said to replace the machine due to the plastic parts that Singer now uses. I will take the machine to a authorized repair center, which is an hours drive, and get an estimate. I don't think I will purchase another Singer in the future when I have had two (2) break within the last 3 years!
