Catastrophic coolant loss due to failure of a known issue by manufacturer. The coolant loss resulted due to failure of the epoxy that held the hose to the manifold. The epoxy failure affected 3 of the hoses. This was part of a DOT bulletin affecting this model year. Failure on my vehicle came later after warranty had expired due to low mileage. Also in 2021 the rear lid spoiler failed (another known high failure issue known to manufacturer) due to hydraulic fluid loss. Both repairs came at a extremely high cost and manufacturer refused consideration for help unless vehicle was repaired at their own dealer. This after I had made contact and advised them of location of vehicle at a service facility that is recognized by manufacturer as a credible alternative to their dealer.
