What owners say
Q70
Overall
Mixed to positive sentiment, heavily dependent on engine choice and model year. The naturally aspirated 3.7L V6 (VQ37VHR) and 5.6L V8 (VK56VD) engines are widely praised for their strong power, reliability, and longevity, with the 3.7L noted as being "rock solid" and the V8 described as "fun as shit to drive." The vehicle is appreciated for its handsome looks, comfortable and capable handling on both back roads and interstates, and spacious interior, particularly in the long-wheelbase (L) models. Significant and consistent criticism is directed at the outdated, overly complicated, and slow infotainment system and gauge cluster, which is described as feeling a generation behind competitors.
Best version to buy
2014 and newer Q70 with the 5.6L V8. This recommendation is based on mechanical quality-of-life updates that addressed known issues from the preceding M56 generation, such as the timing chain and rear-wheel steering.
Known issues
- ⚠Outdated and problematic infotainment system: described as overly complicated, slow, and a generation behind; Bluetooth connectivity issues with multiple phones. Frequency: very frequent.
- ⚠Unresponsive 7-speed automatic transmission: significant lag and delay in kick-down, especially in default and Eco modes; harsh, noticeable shifts; described as having a "dead spot" and being sluggish. Frequency: very frequent.
- ⚠Poor fuel economy: consistently reported as a downside for both the 3.7L V6 and 5.6L V8 engines. Frequency: very frequent.
ES
Overall
Overwhelmingly positive sentiment centered on exceptional long-term reliability, low operating costs, and a comfortable, quiet, and refined driving experience. The ES is consistently praised as a durable, low-stress luxury sedan ideal for high-mileage commuting and long-term ownership. Owners highlight its superior interior materials, sound deadening, and feature content compared to its Toyota platform siblings (Camry, Avalon).
Best version to buy
The hybrid model (ES 300h) is frequently recommended for its significant fuel economy gains (approximately 40 city / 39 highway mpg cited) over the V6, smoother operation, and suitability for commuting. For the V6, later model years (e.g., 2017+) within a generation are often preferred for updates.
Known issues
- ⚠Infotainment touchpad interface: described as annoying, difficult to use; preference for post-2022 touchscreen models. Frequency: recurrent.
- ⚠Steering rack leaks: noted on higher-mileage examples (e.g., 2010 model with 137k miles). Frequency: isolated.
- ⚠CV axle boot leaks: reported after extended high-speed driving. Frequency: isolated.
