We no longer own our 2021 Wrangler but got the recall. Got tired of the "death wobble" and squeaky cap that Jeep refused to deal with. If there's been an investigation by the fire dept to find a root cause I'd highly recommend he get copies. Although insurance has covered the damages it might be interesting to know if Jeep has any culpability at all.
