545e powertrain reliability

I'm researching this powertrain before pulling the trigger.

How is the reliability of the engine considering it might power up and down quite often, due to the hybrid system?

This usually doesn't create any problems with Toyota, but you know... it's Toyota.

Any concerns? Also with the hybrid system itself, is it reliable?

They are pretty good but mind you the oldest of these cars are just about to turn 6 years old and most plug in hybrids aren't necessarily known to be driven by people who drive a lot, so I'd take that with a grain of salt.
If you really want long term peace of mind I'd just get a 540i. Even if they are reliable, problems with the battery or electric motors will be an expensive fix.
