What owners say
TLX
Overall
Mixed to positive sentiment for competent luxury sedan regarded as safe conservative choice offering Honda reliability and value proposition, praised for comfortable plush seats sinking driver into cushioning, spacious trunk and adequate rear seat space (contrary to common criticism), torquey smooth engines delivering effortless acceleration, impressive wide stance creating commanding road presence, attractive interior design avoiding generic touchscreen slapping, premium ELS audio system, and exceptional longevity enabling 250,000-300,000+ mile operation when maintained. However, significant criticism centers on polarizing controversial styling (especially "beak" grille design), jerky rough transmission shifts particularly 2.4L 8-speed DCT and V6 9-speed automatic, cascading electrical warning lights triggered by weak batteries or corroded connectors creating false alarms, outdated infotainment system with frustrating touchpad interface, cramped rear headroom versus exterior dimensions, excessive torque steer (FWD models), AC compressor whining noises and failures, and questionable value proposition versus Honda Accord Touring offering 90% capability at $8,000-$10,000 lower pricing. Overall consensus indicates TLX represents competent reliable transportation and excellent high-mileage longevity proposition commanding $12,000-$22,000 used pricing (2024-2025) though lacks distinctive character, driving engagement, and luxury refinement justifying premium versus mainstream alternatives.
Best version to buy
V6 SH-AWD A-Spec (2018-2020) The 2018-2020 model years with V6 3.5L engine (290 hp), Super Handling All-Wheel Drive (SH-AWD) eliminating torque steer, A-Spec appearance package delivering sportier styling, 19-inch wheels, red or black leather interior with ambient lighting, improved 9-speed automatic transmission (versus problematic earlier years), represent most desirable specification. The 2018-2020 facelift resolved early production issues and refined driving dynamics.
Known issues
- ⚠• Jerky rough transmission shifting, both 2.4L 8-speed DCT and V6 9-speed automatic exhibit harsh shifts particularly 1st-4th gears, bucking sensation at low speeds, abrupt downshifts, not fixable through software updates or fluid changes (…
Legacy
Overall
Mixed sentiment with a strong generational divide. Long-term owner reports for older generations (pre-2010) frequently praise the 3.0R and 3.6R flat-six engines for smoothness and potential longevity, with some examples cited as reaching over 200,000 and even 300,000 miles with proper maintenance. The all-wheel-drive system is consistently highlighted as a key strength, providing excellent capability in snow and adverse conditions.
Best version to buy
3.6R models (equipped with the 3.6L flat-six engine) are most frequently recommended by knowledgeable owners. The 3.6R engine is praised for its smooth power delivery and perceived robustness compared to the standard 2.5L four-cylinder, which is often described as underpowered.

- ⚠CVT transmission reliability concerns: early failures, especially in models from approximately 2014-2015; jerky behavior when cold; requires diligent fluid service. Frequency: very frequent.
