Toyota Motor Corp. said Wednesday that some customer information, such as names and addresses, from the Asia and Oceania regions may have been leaked due to incorrect cloud computing settings, with the total number of affected customers still under investigation.

The announcement comes after the Japanese carmaker said earlier this month that the vehicle information of about 2.15 million customers was publicly accessible due to a similar mistake.

The customer data that may have been leaked this time also included phone numbers, email addresses and vehicle identification numbers. Such information was publicly viewable from October 2016 until May, Toyota said.

Toyota also said the data of about 260,000 Lexus customers in Japan, who used its map distribution service for car navigation systems, may have been publicly accessible. The data included in-vehicle device IDs and the dates when map data was created, it said.

There is no indication that a third party has misused the data, the automaker said.
