Overview

2021 Acura TLX

The 2021 Acura TLX offers a compelling blend of sporty design and premium features, aiming to be a strong contender in the luxury sedan segment. However, for the used car shopper, its appeal is tempered by a concerning reliability record. With 10 recalls and 86 complaints logged with NHTSA, potential buyers must be aware of the significant issues reported by owners. The powertrain, specifically the all-wheel-drive system and transfer case, emerges as a primary area of concern, with numerous failures reported, particularly in Type-S models. Electrical system and brake issues also contribute to the vehicle's below-average reliability verdict. Despite these concerns, the TLX earned top marks in NHTSA crash tests, achieving 5-star ratings across the board. Fuel economy is respectable for its class, with a combined EPA rating of 21 MPG. Prospective buyers should prioritize a thorough pre-purchase inspection, focusing on the drivetrain and electrical systems, and verify all recall work has been completed.

Critical Failure Risk

Numerous reports indicate failures of the transfer case and All-Wheel Drive system, particularly in Type-S models. This can lead to loss of rear-wheel power and potential loss of control, especially in adverse conditions.

Early detection can help you avoid a $2,500-$5,000 repair.
