The BMW X5 reputation varies dramatically by generation and ownership context. Current G05 models (2019+) with the B58 inline-6 earn praise for driving dynamics, luxury, and reasonable reliability when maintained, though a systematic sunroof explosion issue affecting 2024 models raises serious safety concerns that BMW is reportedly denying coverage for. The community consensus is emphatic: avoid older generations (especially 2007-2014 with problematic V8s and early turbo engines) unless you have substantial maintenance budget and mechanical knowledge. Multiple users warn that $15K used X5s will quickly consume another $10K+ in repairs including driveshaft failures, valve cover issues, and electrical problems. For those who can afford proper maintenance or buy CPO with extended warranty, the X5 delivers excellent driving experience. For budget-conscious buyers, the community universally recommends Honda/Toyota alternatives instead.
Mazda built this two-row SUV to deliver luxury materials and a punchy inline-six at thousands below German pricing, but the brand-new platform wasn't ready for showrooms. Rear brakes squeal so persistently that Mazda extended the warranty and redesigned the pads, yet parts remain backordered six months out. Radiators crack at 17,000 miles. Rattles infiltrate the cabin after 20,000. MotorTrend's yearlong tester called it one of their worst long-term vehicles, citing quality lapses that shouldn't exist at $50,000. The CX-90 costs the same, adds a third row, and shares these same problems. If you want Mazda's excellent driving feel without the early-adopter tax, wait for the second model year or choose the CX-50 Hybrid, which uses Toyota's proven powertrain instead of this troubled architecture. Skip this one unless steep discounts compensate for likely warranty visits.
