Heavy monsoon rains over the past week have caused widespread flooding across Bangkok and several surrounding areas of Thailand, disrupting automotive industrial zones and logistics routes and forcing several manufacturers to temporarily suspend production.

Industrial areas in Rayong, Chachoengsao and Chon Buri provinces have been affected, with access for workers and logistics providers disrupted and some component manufacturing facilities reportedly inundated.

Toyota Motor Thailand suspended operations at four plants on September 30th, including its main assembly plant in Ban Pho, Chachoengsao province, which produces the Hilux pickup truck and Fortuner SUV, as well as a facility operated by its Toyota Auto Works joint venture. Toyota said it was working with suppliers to restore component deliveries, although it had not announced a specific restart date at the time of the reports.

Honda Automobile Thailand also temporarily suspended production at its Prachin Buri and Ayutthaya facilities from October 2nd to 6th. Honda President and CEO Koji Iwanami said the decision followed flooding-related disruptions, particularly the inability of component suppliers in Chon Buri and Rayong to deliver parts to the plants.

The two Honda facilities have different functions. The Prachin Buri facility is a vehicle assembly plant, while the Ayutthaya site has been converted to parts manufacturing and no longer assembles complete vehicles. As a result, the Ayutthaya suspension does not represent a second car assembly shutdown. Available reports do not establish that either Honda facility itself was inundated or damaged by floodwaters.

Honda said the suspension also considered the circumstances of employees affected by the flooding. Some employees experienced disruption to their travel arrangements, homes and families, while the temporary closure allowed them to attend to relatives, personal property and recovery needs. Toyota similarly allowed affected employees to take time off to deal with their personal belongings and property.

AutoAlliance Thailand (AAT), the automotive manufacturing joint venture in Rayong co-owned by Ford Motor Company and Mazda Motor, has also suspended operations. AAT postponed the planned resumption of production from October 5th to October 9th, 2026, citing the situation affecting its suppliers, employees and visitors.

The production suspensions are expected to affect vehicle availability and delivery schedules. At AAT, models including the Ford Ranger and Everest are expected to face delays, while Honda production and deliveries, including those of the CR-V, could also be affected.

Honda has indicated that it plans to introduce additional shifts later in October once conditions improve and production resumes, to recover some of the output lost during the suspension and meet customer orders. AAT is also expected to take measures to recover production.

The disruption has affected manufacturers through both production facilities and their supply chains. Reports linked Honda's suspension to suppliers in Chon Buri and Rayong being unable to deliver components, while separate reports on Toyota cited similar disruptions to parts deliveries. Available reports do not establish that the manufacturers shared the same suppliers or experienced identical damage.

For Honda, the expected return of employees on October 7 was a plan rather than confirmation that operations had resumed. Available reports do not establish a final restart status, the total volume of lost production or the financial impact of the disruption. The recovery will depend on the restoration of roads, logistics networks, supplier operations and workforce access.
