Reported issue with ECU exhaust gas recirculation (EGR) valve control programme

Toyota has recalled 2,400 Camry 2.0E sedans in Vietnam over an issue with the engine control unit (ECU) exhaust gas recirculation (EGR) valve control programme, according to a report by the Vietnam News Agency Bulletin. The recalled vehicles were assembled between 6 April 2015 and 1 April 2016. Separately, Toyota also issued a recall notice for 133 Lexus ES 250 and ES 350 cars to fix a brake problem. The affected vehicles were manufactured in Japan between 10 September 2015 and 18 February 2016.

Significance: Toyota Camry is equipped with EGR valves for re-burning gases from the combustion process to reduce the formation of nitrous oxide particulates. In the affected Camry models, the ECU is not programmed properly for the operation of the EGR valves, which can lead to engine stalling at low speed. The recall started on 16 May at Toyota showrooms across the country. It takes around 0.7–1.4 hours to upgrade the software. The Lexus recall is related to the automaker's global recall to fix the braking system. Substandard brake actuators may cause the vehicles' anti-lock braking system and vehicle stability control to function incorrectly. In April 2015, the automaker issued a recall for 15,322 Lexus cars in China to address defective brake actuators. The Lexus recall in Vietnam started on 12 May and the brake actuator is being checked and replaced at Lexus-Thang Long centre in Hanoi and Lexus-Saigon Centre in Ho Chi Minh City. Toyota has also issued a global recall for certain Lexus models over an issue with the fuel pressure sensor.
