Specs side by side
What owners say
Flex
Overall
Mixed to highly positive among owners, with sentiment heavily dependent on powertrain choice and awareness of a critical, well-known mechanical flaw. Owners express deep affection for the vehicle's unique boxy styling, exceptional passenger comfort across three rows, versatile cargo space, and car-like driving dynamics that avoid the bulkiness of traditional SUVs. The EcoBoost turbocharged V6 engine is frequently praised for strong, satisfying acceleration, making the vehicle a "rocket" or "sleeper." However, this enthusiasm is tempered by a very frequent and severe criticism: the failure-prone internal water pump design on the 3.5L V6 engines (both naturally aspirated and EcoBoost), which can lead to catastrophic engine failure and is described as a matter of "when, not if." Fuel economy is consistently criticized as poor (16-20 MPG combined is typical), exacerbated by a small fuel tank, making it a primary reason owners seek replacements.
Best version to buy
Limited trim with EcoBoost engine and AWD. The Limited trim is associated with premium features like leather, rear climate control, and advanced technology.
Known issues
- ⚠Internal water pump failure: Design flaw where the pump is located inside the engine timing cover; failure can leak coolant into the oil pan, leading to catastrophic engine seizure without obvious external leaks.
- ⚠Poor fuel economy: Real-world combined mileage reported between 16-20 MPG, with a small fuel tank leading to frequent fill-ups. A primary reason owners seek to replace the vehicle. Frequency: very frequent.
- ⚠Rust and corrosion: Significant rust issues reported, particularly on door tops under weather stripping, rear hatch seams, and exhaust components (e.g., "flex pipe"). Frequency: recurrent.
XC90
Overall
Sentiment is mixed and heavily dependent on generation and powertrain. For the first-generation P28 platform (2003-2014), long-term owners express strong affection, praising its sturdiness, high-quality feel, and relative mechanical simplicity, especially in later model years with most issues resolved. For the second-generation SPA platform (2015-present), feedback is divided.
Best version to buy
For the second generation, the T8 Recharge plug-in hybrid in higher trims (Inscription, Ultra) is most frequently discussed and recommended for its blend of performance and efficiency. The Bowers & Wilkins audio system is specifically highlighted as a standout feature.
Known issues
- ⚠Software/Infotainment glitches (AAOS): System crashes, laggy response, backup camera failures, frequent need for reboots. Primarily affects 2022+ models. Frequency: very frequent.
- ⚠Hybrid system complexity and reliability concerns: High repair costs for HV components (e.g., on-board charger, high-voltage heater), concerns about long-term durability of the supercharged/turbocharged engine in pre-2022 T8 models, and sp…
- ⚠Poor winter/snow traction in T8 hybrid mode: Embarrassingly bad performance when the gasoline engine needs to engage for traction; requires switching to Constant AWD mode. Frequency: recurrent.
