In June 2010, the route was revealed to be amongst the ten worst performing in London. Two additional morning peak journeys were introduced on 12 June 2010 with the intention of solving the problems; performance improved as a result, although the route continued to receive complaints.
At 08:22 on 17 March 2012, a route 343 caught fire on Pepys Road, New Cross. The fire was put out by 09:20 and there were no injuries.
On 25 June 2019, the route received an extension from City Hall to Aldgate.
