There is nothing weird about lithium ion batteries, including LFPs, degrading quickly under high SOC/high C-rates -- ie, EVs.
We don't know anything about LFP's longevity in EV profile -- ie, high SOC/high C-rates -- and while there is no long-term data to verify LFP's true lifespan in EVs, it's been demonstrated that LFP could lose as much as 1/3 of its lifespan under 100% SOC in ESS profile.
LFP's are already mostly limited to entry-level, low-range EVs due to its other technical short-coming in moving vehicles (ie, low energy density and weight). This quick degradation makes even less appealing in vehicles.
