Overview

2018 Acura MDX

The 2018 Acura MDX offers a comfortable and spacious interior with a capable all-wheel-drive system and excellent safety ratings. However, its value proposition is significantly undermined by a 'Below Average' reliability verdict, stemming from a high number of recalls and frequent complaints related to the engine, fuel system, and electrical components. Potential buyers must be prepared for the possibility of costly repairs and should prioritize a thorough pre-purchase inspection.

Critical Failure Risk

Complaints of engine stalling or hesitation during acceleration are frequent. This is often linked to fuel pump issues (recalls NHTSA 23V858000, 19V060000) or potential connecting rod bearing wear (recall NHTSA 23V751000).

Early detection can help you avoid a $3,000-$8,000 repair.
