When asked about the cases by ABC News, Toyota said that it is not unusual for the company to repurchase vehicles "as part of our commitment to investigate acceleration concerns." According to Toyota spokesperson Brian Lyons, owners are not required to sign confidentiality agreements when a vehicle is bought back, but "they enter into them voluntarily as part of a mutual settlement agreement."
In October, the NTHSA told ABC News it would look into the California and Texas cases, but at today's press conference, NHTSA deputy administrator Ron Medford said the agency had "no ongoing investigations" related to alleged incidents of Toyota technicians replicated sudden acceleration in vehicles.
