What owners say
MDX
Overall
Owners broadly praise the MDX for reliability, driving dynamics, interior comfort, and value, with many describing it as the most reliable vehicle they have owned and reporting zero issues over tens of thousands of miles. The most consistent criticisms are poor fuel economy (especially on the Type S and in city driving), interior creaks and rattles, glitchy infotainment software, and frustrating dealer service experiences. The 3.5-liter V6 is widely regarded as exceptionally durable, while the Type S turbo V6 draws mixed feedback on reliability, with a few owners reporting serious electrical and mechanical failures.
Best version to buy
Insufficient owner data available to declare a consensus. The 3.5-liter V6 (non-Type S) draws the strongest reliability praise, with multiple owners calling it "God-tier" and "bulletproof," while the Type S turbo V6 has both strong defenders and a few reports of serious failures.
Known issues

GV80
Overall
Mixed sentiment with a clear divide between high praise for the vehicle's design, interior quality, technology, and driving experience, and significant criticism regarding reliability, dealership service, and specific mechanical issues. The vehicle is frequently described as offering exceptional value, with a luxurious interior, strong engine performance (particularly the 3.5T), and advanced tech features that often surpass German competitors at a lower price point. However, this positive ownership experience is frequently undermined by recurrent mechanical problems: most notably rear differential/transfer case failures: and a widely panned dealership and service experience characterized by long wait times for parts, lack of loaner vehicles, and poor communication.
Best version to buy
The 3.5T Prestige trim is most frequently cited as the ideal configuration. Owners highlight the superior power and refinement of the 3.5-liter twin-turbo V6 over the 2.5T four-cylinder, and the Prestige trim's Nappa leather and comprehensive feature set.
Known issues
- Rear differential/transfer case failure: causes include unspecified malfunction, part failures leading to long backorders (e.g., multiple months). Frequency: very frequent.
- Dealership/service experience: atrocious customer service, long wait times for appointments, frequent unavailability of loaner vehicles, poor communication, parts delays, issues more pronounced at Hyundai-shared dealerships vs.
- Poor fuel economy: consistently reported as "shockingly bad," a significant negative noted in comparisons. Frequency: very frequent.
