Incidents
From 12 March 2014 to 29 November 2015, Tezonco was closed due to technical and structural faults on the segment between Atlalilco and Tláhuac.

After the 19 September 2017 earthquake damaged Line 12 tracks, Tezonco was temporarily closed for assessments; the station reopened three days later. According to the official report provided by the Metro system, steel diaphragms were placed in the area to provide further support, as the beams and headers were affected.

On 3 May 2021, a section of the elevated line between Tezonco and Olivos metro stations collapsed as a train traversed it. In total, 26 people died and 98 others were injured. After the 2017 earthquake, the Superior Auditor of the Federation (Auditoría Superior de la Federación) made observations of damage to the affected section that were not resolved. On 26 May 2021, the Mexico City Metrobús started a free, temporary route from Tláhuac to Atlalilco station, with a halfway stop at Tezonco station. On 26 August 2022, the line repair team began the dismantling of a girder located 200 m away from the collapse site (in the same interstation section) after finding that its girder could collapse even with the reinforcements that will be installed on the elevated section.
