The short answer
Based on available data, the Alfa Romeo Giulia comes out ahead of the Acura TLX 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
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cascading electrical warning lights triggered by weak batteries or corroded connectors creating false alarms, outdated infotainment system with frustrating touchpad interface, cramped rear headroom versus exterior dimensions, excessive torque steer (FWD models), AC compressor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
Overall
Owners overwhelmingly praise the Giulia's exceptional handling, steering feel, and unique character, often calling it the best-driving sedan in its class. However, this enthusiasm is tempered by widespread frustration with high maintenance costs, a poor dealership experience (especially at shared CDJR locations), and persistent reliability concerns, particularly for early model years. The Quadrifoglio is celebrated as a thrilling performance car, but its reputation for issues and steep depreciation is a recurring theme.
Best version to buy
The Quadrifoglio (QV) is the most praised version for its performance and driving experience, but owners caution that early model years (2017-2019) are risky. The 2.0T Veloce/Ti Sport is well-regarded for daily driving, though some wish for a mid-range V6 option between the base and QV.
