The short answer is that as it pertains to the powertrain, the EV has far less moving parts, so by this fact alone should be more reliable. Other aspects of the EV - the chassis, suspension, cabin are clones of ICE vehicles and would be just as problematic or reliable as ICE equipped vehicles.You think EVs will be immune from this type of issue with suppliers?
Batteries are the EV wild card, the safety and longevity of these is TBD.
