FOTO | "Au băgat locomotive cu abur la STB!" Un autobuz de pe linia 100 fumegă voios pe Bulevardul Regele Mihai, dinspre Arcul de Triumf spre Piața Presei • Știri București

Many public transport vehicles in the STB fleet are old and in poor technical condition, with some posing safety risks. A reader reported a smoking bus on line 100, indicating possible technical failure. The Otokar Kent C model is known for frequent issues, particularly with the particle filter regeneration process and engine cooling systems. The STB fleet consists of 1,640 buses, with significant disparities in their technical state. The problematic Otokar buses, purchased in 2018, have recorded over 26,000 technical failures, especially in electrical systems and cooling. Older Mercedes Citaro buses from 2006 are also heavily worn, with many only suitable for parts exchange.
