Specs side by side
What owners say
RLX
Overall
Deeply divided sentiment for flagship sedan, polarizing owners between passionate enthusiasts praising underappreciated excellence versus skeptics questioning reliability and parts availability. Praised extensively for Sport Hybrid model's exceptional performance (377 hp combined output delivering thrilling acceleration), impressive fuel economy (26-30 MPG combined despite 377 hp), advanced Sport Hybrid SH-AWD system providing exceptional handling dynamics, plush comfortable ride quality, generous standard technology (backup camera, navigation, heads-up display, premium Krell audio), and quiet refined cabin. However, widespread criticism centers on problematic base model FWD (P-AWS) Precision All-Wheel Steer system requiring expensive repairs ($3,000+ parts alone), catastrophic engine seizures reported multiple examples without warning, parts scarcity for low-production model (approximately 1,700 Sport Hybrid units 2014-2020, 1,055 total RLX sold 2020), outdated infotainment lacking Apple CarPlay/Android Auto throughout entire production, premium pricing when new ($60,000-$65,000) unjustified versus competitors, and anonymous bland styling generating no emotional response.
Best version to buy
Sport Hybrid SH-AWD Advance (2014-2020) The Sport Hybrid model universally praised over base P-AWS version representing completely different driving experience. Sport Hybrid delivers 377 hp combined output (310 hp V6 + three electric motors), advanced torque-vectoring SH-AWD system, exceptional fuel economy (26-30 MPG combined), and eliminates problematic P-AWS system.
Known issues
- ⚠• Catastrophic engine seizures, multiple reports of sudden engine failure without warning lights, typically 100,000-130,000 miles range, complete engine replacement required $8,000-$12,000, affects both Sport Hybrid and base models, causes…
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 (…
