The nuts were not tightened sufficiently due to design issues, and could become loose and cause noises, even fall off.
The affected Toyota Avanza and Veloz models were manufactured between Jan. 7 and Oct. 28, 2022, in Indonesia, or assembled in Vietnam between Nov. 14, 2022 and Aug. 14, 2023.
A total of 25,523 Avanza and Veloz cars will be recalled. Also recalled are 448 Yaris Cross cars made in Indonesia between June 2 and Aug. 30, 2023.
There have been no accidents caused by the fault, the Japanese company said.
It also said 6,368 Avanza, Veloz and Raize cars manufactured in Indonesia between Sept. 12 and Dec. 7, 2022, have brake pads that are at risk of failing sooner than designed.
Their front fork dust covers were damaged during assembly, and this could cause dust and water to enter the covers, causing the pads to rust and wear out.
The affected cars will be repaired free of charge at authorized Toyota dealers. The recall began on Jan. 19 and will last until the repairs are completed.
