Statements with "I think" in them don't necessary point to any truths.
Try a Google search and post some data instead!
I found this link with very interesting data:

For a two year period, over the two different fleets, most of the delays were associated with malfunctioning doors, once with inverter failure, and once with brake failure. Some cars have had problems with their air conditioners - while affecting passenger comfort during the summer months, they have not caused train delays.

TC has 370 T1 subway cars and 480 TR subway cars. If over a two year period only 5 instances of operations delays of more than 5 minutes for T1 cars and 8 instances for TR cars, that's actually quite good.
Some math follows:
370 + 480 = 850 cars. 365 x 2 = 720 days. 850 x 720 = 612,000 car-days. During this period only 13 delays caused by the cars. 13/612,000 = 0.000021241830065, or 0.002124183006536% failure rate.
And that's per day, not per trip. These cars must make several round trips every day.
