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 However, criticism includes outdated technology by modern standards (no Bluetooth, basic infotainment in early years), thirsty fuel consumption (16-19 MPG combined), transmission issues affecting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.
Best version to buy
3.5L V6 with Technology Package (2004-2006) The 2004-2006 model years preferred for revised 265 hp engine (versus 240 hp 2001-2003), improved transmission calibration addressing early issues, and Technology Package adding navigation, rear entertainment, premium audio. The SH-AWD (Super Handling All-Wheel Drive) system standard across all trims providing excellent winter traction and handling dynamics. 2005-2006 final years represent most refined iteration before second-generation redesign.

SRX
Overall
Sentiment is sharply divided and heavily dependent on model year, powertrain, and maintenance history. The second-generation model (2010-2016) is frequently described as a significant reliability and financial liability, with very frequent reports of catastrophic and expensive failures involving the transmission, 3.6L engine (particularly timing chains), and electrical systems. Owners who experience these issues characterize the vehicle as an absolute money pit that falls apart after 5-6 years and plummets in resale value.
Best version to buy
Insufficient owner data available to declare a consensus "best" version. Anecdotal praise exists for well-maintained examples of the 2014 SRX Premium with the 3.6L engine, and for the first-generation V8 AWD models with the MagnaRide suspension.
Known issues
- ⚠Transmission failure: complete destruction, slipping, shifting problems, torque converter shudder. Described as a $3,800+ repair. Frequency: very frequent.
- ⚠3.6L Engine timing chain problems: expensive repair ($2,000-$4,000), engine failure, driveability issues. Frequency: very frequent.
- ⚠Headlight system failures: complete burnout, extremely dim output, particularly on 2016 models. Requires replacement with potential need for CANbus regulators for LED upgrades. Frequency: very frequent.
