A plush three-row that trades on deep discounts and a hushed cabin, but the 2018-2024 generation carries a documented transfer case weakness. Multiple owners report the same failure: the case splits catastrophically at highway speed, dumping fluid and stranding the vehicle, sometimes with only 30k-70k miles on the clock. When it works, you get adult-sized third-row space, a genuinely quiet ride, and dealer incentives that undercut Honda and Toyota by thousands. The catch is you're rolling dice on a known mechanical fault, and mismatched tires accelerate the failure. The all-new 2025 redesign swaps the V6 for a turbo four and starts fresh on a new platform, so the old gremlins shouldn't follow, but there's zero long-term proof yet. Buy used and you're gambling; buy new and you're hoping Buick learned its lesson.
The Model X is Tesla's swing-for-the-fences family hauler, falcon-wing doors, a windshield that feels like a greenhouse, and Plaid acceleration that pins you to your seat, but it's also the poster child for ambitious engineering meeting real-world entropy. The 2019 battery packs fail catastrophically (sense wire defects forcing $12, 21k replacements), brake lines corrode early from poor placement, and the falcon doors that wow at pickup become alignment headaches years later; add tire bills every 15k miles, half-shaft swaps, and steep depreciation, and you're looking at a high-maintenance relationship. Buy a low-mileage post-2021 refresh if you need three rows and love the Supercharger network enough to budget serious upkeep, but skip the early years entirely, and walk if you want a luxury SUV that just works.
