Specs side by side
What owners say
QX4
Overall
The sentiment among owners is overwhelmingly positive, characterized by strong appreciation for the vehicle's durability, reliability, and comfort. The QX4 is consistently praised as a robust, long-lasting SUV capable of reaching very high mileages (300,000 to 400,000 miles/480,000 to 640,000 km) with proper maintenance. Owners value its comfortable ride, practical size, and the perception that it was built during a period of high quality for Nissan/Infiniti.
Best version to buy
Insufficient owner data available to specify a model year or trim as the definitive "best version." Feedback spans the entire 1997-2004 production run, with specific issues (like strut tower rust) tied to certain years but not definitively isolated to a single model year in the provided data. The vehicle's reputation for longevity is applied broadly across the generation.
Known issues
- ⚠Structural rust in front strut towers: can lead to collapse and loss of control; subject to a manufacturer recall/campaign. Frequency: recurrent.
- ⚠Oil consumption: the 3.5L V6 engine (VQ35DE) is noted as being prone to burning oil; requires regular level checks. Frequency: recurrent.
- ⚠Idle and hesitation problems: issues with idle air control, throttle position sensors, mass air flow sensors, and potential vacuum leaks causing rough idle and acceleration hesitation. Frequency: recurrent.
4Runner
Overall
The sentiment is overwhelmingly positive regarding legendary long-term reliability, durability, and off-road capability, particularly for the 5th generation and older models. The 4Runner is consistently described as a "tank," an "over-engineered masterpiece," and a vehicle that will "outlive everything else on the road." Owners report minimal repair needs and high satisfaction with its ruggedness and practicality for camping and overlanding. However, feedback on the newer 6th generation (2025+) is mixed and more critical.
Best version to buy
5th Generation (approx. 2010-2024): Specifically, older 5th-gen models (e.g., 2015-2019) are highlighted for their proven mechanical simplicity, absence of complex new technology (like Toyota Safety Sense), and the legendary reliability of the 4.0L V6 engine and 5-speed automatic transmission. These are recommended over newer 5th-gen models with added technology that can be "finicky" and expensive to repair.
Known issues
- ⚠Excessive frame rust: Boxed frame design can trap moisture and salt, leading to severe corrosion from the inside out, potentially causing structural failure. Frequency: very frequent.
- ⚠Unrefined powertrain in 6th-gen (2025+): Rough upshifts and downshifts, abrupt power delivery from turbo and hybrid battery, general lack of smoothness compared to older V6. Frequency: recurrent.
- ⚠High pricing / poor value: New models (especially 6th-gen) criticized for high MSRP relative to interior material quality, feature content, and fuel economy. Frequency: recurrent.
