That's because it's a much heavier vehicle, which stresses the motor (and creates more heat).
Similar to how Volvo offers only 4cyl engines on even it's largest SUV's. They are constantly stressed by weight, but also have dual chargers (turbo and super) which generates ample heat.
OTOH, the Honda's mentioned in the article a far lighter vehicles (as proven by their stellar fuel economy).
In the long run, all this negative PR cannot be good on Honda's bottom line.
