So just had a 3rd kid and in the market for a big SUV. Wife is leaning towards the latest escalade. I've seen some talk on forums of various quality issues (lifters, etc) during the covid production era and it scares me a little bit. Is it a bad move to buy a 2021/2022 that is used but still under warranty? Looks like it can save me ~$15K but a headache car isn't worth it in the long run. Any opinions?
