The extra weight of the vehicle will make the suspension and some other parts work harder and maybe some of these parts are not up to the harder task, maybe, maybe not?? QC problems, maybe, maybe not.
The article did not mention something that could be playing a part here. ICE vehicles go in for oil changes, new ones commonly at the dealer. They are always looking for add-on service and will give all these parts a look-see and that may end up in them getting fixed before the government inspection. The EV does not have anywhere near the same level of service touch so things could just be wearing out at a similar rate, they are just not getting noticed until the required inspection.
