So what the fuss about if the NiMH pack fail totally time?
The car cannot start, cannot move, then just tow away, and change a new pack.

Even ordinary car, time belt can be broken after 80-100k KM, and car cannot even start also.
Radiator leaking, water pump leaking, car also cannot start.
Just tow away and get it fix.

Every ordinary car after 8-10 years, parts also got spoil here, spoil there.
Choose a car just because can start even if NiMH pack fail time that may only happen once after 8 years or even longer period?
NiMH fails, just change one.
What is the worry?
I don't find this is a good reason to say this is a good car or not.

T or H doesn't pay us to be fanboyism, instead we paid our hard-earned money to own one. 
Paid 100k then still provide free self service to promote and posting fanboyism comment? 

Unless they do pay us or give special discount for fanboyism, then different story. 

Every car has its own drawback and advantage.
If A car has advantage over B car, even we own B car, we just said A is better built car.

One likes the car, because you like the car, not because the car is the best or better than others.
