What owners say
MDX
Overall
Overwhelmingly positive sentiment for first-generation model, widely regarded as groundbreaking luxury three-row SUV establishing segment template and Honda reliability reputation. Praised extensively for exceptional longevity with examples routinely exceeding 250,000-300,000 miles (402,000-483,000 km), comfortable ride quality, spacious three-row seating accommodating adults, powerful 3.5L V6 engine (240-265 hp depending on year), and low maintenance costs typical of Honda engineering. Owners report emotional attachments spanning 15-20+ years and multiple hundred thousand miles, describing MDX as "best vehicle ever owned" and "family member." However, criticism includes outdated technology by modern standards (no Bluetooth, basic infotainment in early years), thirsty fuel consumption (16-19 MPG combined), transmission issues affecting some high-mileage examples beyond 200,000 miles, and typical Honda third-row tightness for adults.

XT6
Overall
Mixed to negative sentiment overall, with a significant divide between initial appeal and long-term ownership experience. The vehicle is consistently praised for its comfortable ride, spacious three-row interior, attractive design, and strong value proposition when purchased at a steep discount or used. However, widespread and severe criticism centers on poor build quality, frequent mechanical and electrical failures, and outdated technology.
Best version to buy
Insufficient owner data available to identify a consensus "best" trim. The Sport trim and Platinum trim are mentioned, but feedback is focused on issues rather than trim superiority.
Known issues
- ⚠Poor build quality and premature squeaks/rattles: interior noises developing within the first few thousand miles. Frequency: very frequent.
- ⚠Mechanical and electrical failures: includes complete vehicle shutdown at an intersection, persistent no-start conditions, failing driver assistance system sensors, faulty rearview mirror displays, and failing liftgate hydraulics.
- ⚠Outdated and problematic infotainment system: described as technology from circa 2016, with constant pop-up messages that must be cleared, laggy response, and an obnoxious user interface. Frequency: very frequent.
