Specs side by side
What owners say
Pacifica (minivan)
Overall
Mixed sentiment with a clear divide between powertrain types. The conventional gasoline-powered Pacifica (2017+) receives generally positive feedback for its driving dynamics, interior comfort, practicality, and feature content, particularly the Stow 'n Go seating system. Owners describe it as a superb vehicle to drive, with a comfortable ride, good power from the 3.6L V6 engine, and a well-implemented 9-speed automatic transmission.
Best version to buy
Gasoline-powered models (non-hybrid) are consistently recommended over the Plug-in Hybrid variant due to far fewer reported major reliability issues. The Limited trim is frequently mentioned for maximizing luxury and technology features.
Known issues
- ⚠Plug-in Hybrid (PHEV) powertrain failures: Catastrophic transmission failures requiring complete replacement, battery failures, loss of power while driving, software glitches. Frequency: very frequent.
- ⚠Engine failure (gasoline models): Isolated but severe reports of engine failure in the 60,000-80,000 mile range, with one specific report of a 2018 model failing at 79,000 miles. Replacement cost cited at approximately $15,000 USD.
- ⚠General reliability / build quality concerns: Higher likelihood of small electrical issues, switch failures, and overall lower perceived durability compared to segment leaders. 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
- ⚠Transmission problems (2017 models): Jerkiness, shifting issues, high-speed freeway problems, and expired customer service programs for repairs. Frequency: recurrent.
- ⚠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.
