The company found a gap between the slate's screen and casing that left it susceptible to water damage, Reuters reports.
A spokesperson for the electronics giant told the news agency that a "manufacturing flaw" at the Chinese factory where the product is made is responsible for the fault.
Sony has already distributed around 100,000 Xperia S tablets so far in Europe, the US and Japan, but has given no indication about when the device could return to the market.
Customers who have already purchased the product are able to return it to Sony for a full check-up, during which any faults will be corrected.
The Sony Xperia Tablet S retailed in the UK from £329, with the price tag climbing for models with higher memory.
