There was no immediate response from Sony to an email from CNBC regarding the glitches in the new PS4.
In a report about the PS4 in the Huffington Post, a Sony representative was quoted as saying: "We are closely monitoring for additional reports, but we think these are isolated incidents and represent a very small percentage of total units shipped to consumers to date."
Sony is expected to release the PS4 in Europe and Latin America this Friday and in Japan next February.
