The São Paulo metro system has experienced multiple service disruptions due to technical failures on different lines.

On September 16, a power failure on Linha 4-Amarela affected the section between Paulista and República stations. The outage caused passengers to be trapped in dark train cars, with some commuters walking through tunnels via emergency walkways. The concessionaire, Motiva, suspended circulation to ensure safety and deployed emergency bus services, with operations normalizing by approximately 8:15 a.m.

On September 24, Line 5-Lilás faced disruptions caused by equipment failures near Santa Cruz and Capão Redondo stations. These issues resulted in reduced train speeds and longer service intervals. The concessionaire, ViaMobilidade, reported that maintenance teams were working on the problems and planned to carry out necessary repairs after operations concluded.

In a separate development regarding service availability, the São Paulo Metro announced that its experimental 24-hour weekend operation will be extended until January 31, 2027. This continuous service applies to Lines 1-Blue, 2-Green, 3-Red, and 15-Silver, facilitating uninterrupted travel from Saturday to Sunday mornings. Since the initiative began in December 2025, the system has recorded approximately 665,000 overnight trips. The Metro is currently monitoring demand and the impact of continuous operation on maintenance schedules. This 24-hour service does not include Lines 4-Yellow and 5-Lilac, which are managed by private concessionaires.
