Toyota Motor Thailand and Honda Automobile (Thailand) have temporarily suspended vehicle production at all their assembly plants in Thailand as severe flooding disrupts transport routes and parts deliveries.
The disruption followed accumulated rainfall of more than 320mm in three days, leaving major transport corridors heavily flooded and preventing suppliers from reaching assembly lines.
Honda Shuts Ayutthaya And Prachin Buri Lines
Honda Automobile (Thailand) suspended vehicle production at its Prachin Buri and Ayutthaya plants from October 2 to 6 after suppliers in Chonburi and Rayong provinces were hit by flooding, cutting off component deliveries.
Koji Iwanami, president and chief executive of Honda Automobile (Thailand), confirmed the target restart timetable while granting emergency leave to affected facility staff.
“The company has temporarily suspended vehicle production at the Prachin Buri and Ayutthaya plants from Oct 2 to 6 because parts suppliers have been unable to deliver components required for vehicle production after being affected by flooding, particularly in Chonburi and Rayong provinces,” Iwanami said.
Plant managers plan to introduce overtime shifts once lines restart to clear model order backlogs and recover lost output.
Toyota Halts Four Thai Assembly Facilities
Toyota Motor Thailand ceased work across its three primary manufacturing plants in Samut Prakan and Chachoengsao, alongside affiliate facility Toyota Auto Works. The company runs the Samrong facility in Samut Prakan together with the Ban Pho and Gateway plants in Chachoengsao.
Submerged access routes broke the parts delivery cadences needed to support Toyota’s just-in-time production system. Plant managers are scouting alternate logistics bypasses and assessing inventory buffers to restart operations once floodwaters drain.
Supply Chain Bottlenecks Expose Tight Logistics
The manufacturing halts show how little inventory cushion exists in Southeast Asia’s primary automotive export hub. When arterial roads connecting the Eastern Economic Corridor’s parts cluster in Rayong and Chonburi get blocked, assembly lines outside Bangkok stall within hours regardless of plant floor safety.
Car manufacturers in Thailand remain heavily exposed to single-route logistics risks. While suppliers upgraded localized drainage barriers after historic monsoon disasters in past cycles, external transport corridors between provinces remain vulnerable to acute flash flooding.
Industrial Losses Mount Across Fifteen Provinces
Federation of Thai Industries data show that flooding between September 24 and September 30 hit Bangkok and 14 surrounding provinces, affecting roughly 40 per cent of member operations in flooded districts. The group calculated preliminary losses of at least 1.018 billion baht ($38.7 million) across automotive assembly, parts suppliers, machinery damage, damaged vehicles and lost factory shifts.
Industrial estates across Chonburi absorbed the bulk of direct supplier delays. Toyota and Honda are watching municipal drainage rates on key industrial arteries ahead of Honda’s scheduled production restart on October 7.
