Specs side by side
What owners say
X7
Overall
Mixed sentiment with a clear generational divide. The pre-facelift models (approximately 2019-2022) are generally praised for their excellent driving dynamics for a large SUV, luxurious and spacious cabin, strong B58 inline-six engine reliability, and superb highway comfort, making them a favored family hauler and road trip vehicle. However, the 2023+ facelift (LCI) models attract significant criticism for a perceived step back in interior design and user experience, centered on the new curved display and touchscreen-dependent controls, described as distracting, overwhelming, and less user-friendly than previous systems.
Best version to buy
Pre-facelift models (approximately 2020-2022) with the xDrive40i (B58 inline-six) engine and a Certified Pre-Owned (CPO) warranty. These are frequently cited for their more traditional, user-friendly iDrive 7 interface with physical climate controls, proven reliability of the B58/ZF8 powertrain, and strong value due to depreciation.
Known issues
- ⚠Drivetrain/Transfer Case Failure: Complete failure or severe shudder, requiring very expensive repair (quoted up to $9,000 USD). Frequency: recurrent.
- ⚠Facelift Interior/Infotainment Criticism: Overwhelming curved display, loss of physical buttons and knobs (especially flimsy vent controls), touchscreen-dependent climate controls causing delays, distracting and ostentatious ambient lighti…
- ⚠Electronic Bugs & Glitches: Random "Chassis" errors requiring restart, infotainment freezes, ventilated seats activating heat instead of cooling, transmission randomly shifting to manual mode. Frequency: isolated.
TX
Overall
Mixed sentiment with a clear divide between expectations and reality. The vehicle is widely praised for its practical strengths: a genuinely spacious and usable third row, good cargo capacity, a quiet and comfortable ride, and the perceived long-term reliability associated with the Lexus brand. It is frequently positioned as a sensible, family-focused luxury SUV offering a stress-free ownership experience.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Feedback indicates trade-offs: the TX 500h (hybrid) is praised for its smoother, more powerful acceleration, but some find its seats less comfortable than the TX 350.
Known issues
- ⚠Disappointing interior material quality: described as bland, gray, with hard plastics, limited color options, and a perceived downgrade from previous Lexus models. Frequency: recurrent.
- ⚠Confusing trim and package structure: overly complicated, making it difficult to determine which features are included in a specific vehicle. Frequency: recurrent.
- ⚠Real-world fuel economy significantly below EPA estimates: specifically for the TX 500h hybrid, with reports of 18-25 MPG in mixed driving versus advertised 27 city/28 highway. Frequency: recurrent.
