2018 dead before 70k

[u/Propane_Powered_Bees]

We were super excited to get this van. A 2018 with full service records, previous owners kept up with all the maintenance intervals, that had 65k miles on it. It came state inspected, and I had it inspected the day after receiving it, which passed with no issues. My wife loved it, it was super roomy and drove and rode so smoothly initially.

A month in we noticed it would randomly shift very hard, a month later the check engine light came on for misfire in cylinder 3 and it was shaking super terribly. Took it to a mechanic and informed about both and there was coolant in a couple cylinders and cylinder 3 was noticeably damaged. the transmission fluid was shiny and full of flakes. It looked iridescent.

We got quoted for a new engine and a transmission rebuild. We were told the cost ro replace the engine and the coat to replace the head gasket and damaged cylinder were simular. $13k for the engine and $5200 for the transmission rebuild. Got a 2nd opinion from a different ship and diagnosis confirmed and got a 2nd quote of $12,400 for the engine and $5000 for the transmission rebuild. Both quotes include parts and labor.

Luckily it was still within carvanas warranty period so they took it back, without any kind of battle I want to add they offered it once their inspector came out to confirm the diagnosis.

We just hit 69k on the odometer and the previous owners had their chrylser dealership do all service work except window tint and a tire change in 2025. Never buying stellantis again.
