Specs side by side
What owners say
Astro
Overall
Sentiment is overwhelmingly positive regarding the vehicle's core reliability, durability, and practicality, particularly for its era. The Astro is consistently praised for its robust 4.3L V6 engine, with multiple reports of achieving high mileage (300,000+ miles/483,000+ km) with regular maintenance. It is highly regarded as a versatile platform for van life conversions, camping, and work use, offering a good balance of interior space, power for mountain passes, and a commanding driving position.
Best version to buy
All-Wheel Drive (AWD) models are frequently mentioned as the preferred configuration for improved traction and versatility, especially for camping or use in varied climates. Later models (approximately 1996 and newer) with the Vortec 4.3L V6 and electronic fuel injection are implicitly favored over earlier carbureted versions due to improved driveability and reliability.
Known issues
- ⚠Rust on frame and body: A very frequent and critical concern, often cited as a primary reason to avoid a specific vehicle. Frequency: very frequent.
- ⚠Electrical problems: Intermittent no-crank/no-start conditions, faulty door lock actuators (especially front doors), wiring harness damage (notably above the gas pedal), and general electrical gremlins. Frequency: very frequent.
- ⚠Suspension and steering component wear: Worn ball joints, leaf spring failure (including broken/welded springs), and failing power steering pumps are common high-mileage wear items. Frequency: very frequent.
Sienna
Overall
Overwhelmingly positive sentiment regarding long-term reliability, practicality, and fuel efficiency, particularly for the hybrid models (2021+). The Sienna is consistently praised as a durable, low-maintenance family vehicle capable of reaching very high mileages (200,000-300,000+ miles) with proper care. The hybrid powertrain is highlighted as a major advantage, offering significant fuel savings (approximately 36 MPG) compared to competitors.
Best version to buy
For newer generations (2021+), the Platinum trim is frequently recommended for its comprehensive feature set, including ventilated/cooled front seats, a video rearview mirror, and advanced safety technology. The hybrid powertrain is considered non-negotiable for its fuel savings and reliability.
Known issues

- ⚠Infotainment/system glitches (2025 models): Profile and key fob pairing failures, unresponsive screens. Frequency: isolated.
- ⚠Engine issues (specific older models): Timing chain/crankshaft codes (P001500, P001700) on a brand-new 2025 model; oil/coolant leaks and timing chain failure on a 2015 model. Frequency: isolated.
