Overview

2015 Acura TLX

The 2015 Acura TLX presents a mixed bag for used car shoppers. While it boasts excellent NHTSA safety ratings (5/5 stars) and a respectable 25 MPG combined, its 'Below Average' reliability verdict and a substantial number of recalls (40) and complaints (517) demand careful consideration. The primary concerns revolve around the powertrain and engine, with widespread issues reported. Potential buyers must factor in the possibility of costly repairs and conduct a rigorous pre-purchase inspection.

Critical Failure Risk

The ZF 9-speed automatic transmission is notorious for rough shifts, hesitation, and jerky movements, particularly between gears and in stop-and-go traffic. This can manifest as feeling 'rear-ended' or a general lack of smoothness. Software updates have been issued, but some owners report persistent issues.

Early detection can help you avoid a $0-$7,000 repair.
