Questions about ERAD failures

I have owned a 2016 XC90 T8 Twin Engine for 3.5 years now. Bought it at 111 000 km ( 68 900 mi ) and now it's at 185 000 km ( 115 000 mi ).
During the 3.5 year ownership I've never had an ERAD issue. I do believe my car is on the ERAD1 since it's the first model year in this generation. I actually was not aware of ERAD failures when buying the car. I'm obviously not a car person.

But now I'm looking at a newer XC90, model year 2021 onwards and below 60 000 km ( 37 000 mi ).

After reading through the forums, I'm thinking again. So many people have reported ERAD failures, with some people even reporting a catastrophic ERAD explosion, with the casing tearing apart.

As far as I knew, Volvo was great at making extremely sophisticated drivetrains. This forum is slowly changing my opinion.

I would really appreciate if T8 owners would share their real-world experiences and thoughts on this. Whether the ERAD failure is a " when " question rather than if.

Reading the forum gives me a feeling that people tend to get a picture that Volvo isn't safe as a brand on the engineering side, and reliability is also poor. It would be good to have many owners reporting their " good " experiences as well, as often only the bad gets highlighted. Just so we aren't scaring people away from buying the safest cars on the planet.

Thanks

Depends on your definition on "when".... every mechanical part fails eventually. I'd trust anything we make today 100 times over your 2016. Forums will always point out the worst of things though because the internet is where folks come to complain. That being said, ERADs fail more than engines, but not usually blowing up the case.

As for Volvo and sophisticated drive trains, their history is more of simply reliable designs. The drive e motors have been pretty good since 2017, but any repair gets spendy on labor.

What I've not seen is a reasoning to consider for ERAD failure. Is it more EV us or more mixed driving that has the higher tendency? Is it the engagement or use of that causes it? Is it a wear issue or occasional manufacturing defect?

This is what I would also like to know.

But then again, ERAD is not THAT expensive of a fix as I understand. Sure it's a few grand and it sucks when you have to pay it out of the pocket but it's not like insurances are exactly free either. Insurances are business and on average you can bet they make money of those so on average you'll lose money by having insurance as opposed to not having an insurance. But many people pay happily a small premium for the peace of mind that if something (or a lot of things) break then it won't break the bank as well.
