Damper / Rattle on start up

[V2WIN]

While researching Toyota hybrid problems I found a couple that matches issues on our forum. Damper-- It appears the springs & rivets are the problem. They get loose & the damper rattles until a load is applied. Rattle on morning start ups. It appears that the head gasket fails allowing coolant into a cylinder. The piston hydraulics & if the gasket isn't changed will push the connecting rod out the side of the block. My first thought of why the recall was for crank not polished to spec, but I think this head gasket problem is the culprit. If you get the Rattle. I suggest having yours towed to dealer for a gasket inspection. If I get it I will pull the spark plugs & look in each cylinder with a bore scope. If any coolant is seen to the dealer it will be towed with a video of results. BTW these are issues Toyota hybrid have too.

Aside from both being hybrids with a distant shared engineering lineage there really is no relevance. Completely different ICE and probably different damper suppliers.

Possible, but they sure look the same, & both are 2.5 Atkinson engines. Food for thought. The you tube video was showing quite a pile of Toyota 2.5 with rod hanging out the side of the block. Ford had to do the underwood recall for something they won't tell.

Mine is rattling and has misfire check engine lights. Noise is coming from the transmission, same with the escape hybrids. My dealer suspects the clutch assembly is throwing something off. It’s going in to have the engine and transmission taken out so they can inspect and replace. Absolute disaster of an experience for me. I got the 100,000 mile extended warranty. I don’t plan to keep it 1 mile longer but honestly don’t anticipate it even lasting that long.
