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.
Mercedes built its bestselling SUV on a solid foundation, the 2016-2022 GLC earned genuine loyalty with 100k-mile trouble-free runs and that swanky interior. But the 2025 GLC 350e plug-in hybrid is stranding owners with complete electrical shutdowns while driving, triggering lemon law buybacks in California. Mercedes calls it a software glitch; owners wait weeks for parts from Germany while their $60k SUV sits dead. The standard gas models look promising with refined engines and improved cabins, but thin long-term data means you're betting on Mercedes fixing what broke between generations. Budget for warranty coverage, repair bills hit $5k-6k when things fail, and modern Mercedes complexity makes that a when, not if.
