Despite the decline in reliability, TTC spokesperson Stuart Green said the agency is generally satisfied with the new streetcars. Public TTC reports show the streetcars they have consistently failed to reach reliability standards spelled out in the contract. The TTC and Bombardier have repeatedly made statements reassuring the public the number of failures the cars exhibit will decrease as Bombardier perfects its production processes. Ernst wrote that in order to meet the reliability target, the cars should be exhibiting just 15 failures per month. According to the TTC, Bombardier issued the bulletin out of an abundance of caution after a problem with loose fasteners on a brake caliper was discovered last year.
