Well Endurance decided to cover the claim. At first they wanted the last three oil change receipts, but then magically they no longer needed them after the dealer repeatedly told them it had nothing to do with oil change intervals and that the oil was good (obviously we know it isn't, but it got the claim approved). Ironically Endurance agreed to an oil change to be covered but not a coolant flush and fill. The dealer also stated that the catalytic converter needed to be replaced along with the o2 sensors because of the burning of coolant. I opted not to do that right now because of the price. I'm responsible still for $1050 of the repairs. Endurance is covering $2100. My part is misc. things that aren't covered like seals for sensors, spark plugs, random little things that add up. I think the price is still a little high, but I'm thinking it's the dealer milking everything they can at this point. I don't care I just want my van back and back right. Now it's a matter of them getting it in for the repair. Apparently the next booking isn't until February the 6th. Ugh...
