The short answer
Based on available data, the Volvo XC90 comes out ahead of the Acura MDX on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
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
Overall
Sentiment is mixed and heavily dependent on generation and powertrain. For the first-generation P28 platform (2003-2014), long-term owners express strong affection, praising its sturdiness, high-quality feel, and relative mechanical simplicity, especially in later model years with most issues resolved. For the second-generation SPA platform (2015-present), feedback is divided.
Best version to buy
For the second generation, the T8 Recharge plug-in hybrid in higher trims (Inscription, Ultra) is most frequently discussed and recommended for its blend of performance and efficiency. The Bowers & Wilkins audio system is specifically highlighted as a standout feature.
