Rea Vaya is halting its services following a shooting on Monday night.
Taking to social media, the bus company said its services are temporarily suspended until further notice.
"Rea Vaya Passengers are advised that buses are temporarily suspended until further notice due to shooting incidences to bus drivers that happened last night in Soweto. We advise passengers to use alternative public transport. Regular updates on the situation will be given," the post read.
Last year, Rea Vaya was locked in a legal spat with a taxi association after its new fleet launch was disrupted. At the time, the Saturday Star reported that the taxi association claimed the buses were deployed with the wrong registration plates.
This incident comes a week after 51 Putco buses were torched in Mpumalanga.
It is alleged that a group of suspects, driving a white Toyota Quantum set the buses alight.
In the first incident, 16 buses were burnt at Kwamhlanga, more were burnt across three other locations.
Mpumalanga police spokesperson, Brigadier Donald Mdhluli, said security officers were injured during the attacks.
Police have since arrested two men, aged 29 and 37 on charges including malicious damage to properties, and business robbery.
