Front driver wheel had a hub bolt back out rendering the vehicle unable to drive. The car made a loud grinding noise and was unsteady. I had to pull over and was unable to drive any further. It required replacement of the hub bolt and axel. This is a known problem for rivian’s and has not been addressed or checked. I reported a grinding sound when I turn 2 months ago and was told that the soonest Rivian could service my car was 2 months away. This known problem and complaint should have flaggged an immediate intervention and this needs a recall.
