The problem/issue, as I see it... French cars are renowned for having bad electrical systems to start with... How can they possibly build an electric car, and convince us that it's going to be reliable....
I believe the Zoe has been one of the most reliable Renaults in a while! However, a PHEV is always going to be very complex which is never good for reliability.
My brand new Toyota Avensis from 2012 was the worse car i ever owned. I had to drive to the workshop 5 times in 1 year.... sold the car right after they fixed the largest issue that was the engine misfiring and going into emergency mode. All i am saying is that these days its a gamble with whatever car you buy, i had the best of luck with 5 out 6 of my BMWs, most people say they have problems with theirs... i had none. Just buy the car you like and make sure you have a friendly and helpful workshop. That's all that matters really. We own a e-208 that is full electric and we are extremely happy until now with how easy it is to live with. Practical and awesome looking. The shop has been helpful until now to all our questions and requests so i am not stressed for it, for now at least.
