The STM says as of yet it has no plans to take 850 recalled buses out of service after it found no particular problems in a spot check this week, adding that doing so would cripple the transport company's fleet.
STM chairman Philippe Schnobb says the problem, associated with an alternator cable, has seen some Nova Buses begin smoking from the engines, but the problem hasn't appeared on any STM busses in service
There was one case of an STM bus smoking from its engine, but it was while parked in a garage, and remains out of service, according to an STM press release.
Schnobb says for now Montreal's public transport service is awaiting new directives from Nova Bus on when any repairs will take place or replacements be available.
"We're waiting for Nova Bus, they're [sic] supposed to tell us at the end of the month around the 29th of August what we're supposed to do," he said.
"For now, we don't know [what it will recommend] so what we'll do is be vigilant and we'll check to see for any smoke or fumes coming from the engines."
