Specs side by side
What owners say
Q5
Overall
Mixed sentiment with a clear dichotomy. The vehicle is consistently praised for its superior driving dynamics, handling, and refinement compared to mainstream and some luxury competitors. Owners frequently describe it as "fun to drive," "super quiet and smooth," and possessing a solid, tank-like build quality.
Best version to buy
The 3.0T supercharged V6 engine (found in pre-2017 Q5 models and in the SQ5) is very frequently recommended over the 2.0T four-cylinder for its power, refinement, and perceived reliability. For newer generations, the plug-in hybrid Q5 e is suggested as a high-feature, powerful, and efficient alternative to the performance-oriented SQ5.
Known issues
- ⚠High maintenance and repair costs: very frequent mentions of routine services costing $1,400-$3,000, with out-of-warranty repairs described as exceptionally expensive. Frequency: very frequent.
- ⚠Electronic/Infotainment glitches: includes CarPlay/Bluetooth connectivity failures, random system reboots, unresponsive screens, and parasitic battery drain causing "Low Battery" warnings in new models (e.g., 2025).
- ⚠Sunroof leaks: noted as a design flaw in some generations (e.g., Q3/Q5), requiring extensive disassembly and often recurring. Frequency: recurrent.
GX
Overall
Sentiment is sharply divided by generation. The previous-generation GX 460 (model years up to 2023) is overwhelmingly praised for its legendary reliability, proven V8 powertrain, comfortable and durable luxury, and high long-term value. Owner feedback describes it as a "bulletproof," over-engineered vehicle that benefits from decades of refinement, with a 10-year cost of repairs reportedly half that of competitors.
Best version to buy
For the GX 460 generation, the final model year (2023) is specifically highlighted as the "one to have" due to receiving the latest updates and a newer infotainment system with Apple CarPlay/Android Auto. The Luxury trim is highly recommended for its adjustable ride control (Comfort/Sport settings), which owners find invaluable for tuning ride quality on different road surfaces.
Known issues
- ⚠**GX 550 (2024+):** Major engine recall (V35A-FTS twin-turbo V6): Safety recall for machining debris causing potential bearing failure and catastrophic engine seizure. Linked to broader issues with Toyota/Lexus's new turbo engines.
- ⚠**GX 460 (Pre-2024):** KDSS system leaks: Failure of the Kinetic Dynamic Suspension System front piston, leading to expensive repairs ($4,000+). Frequency: recurrent.
