2012 Acura RDX

The 2012 Acura RDX marked a significant shift for the model, moving away from the turbocharged engine of the previous generation to a naturally aspirated 3.5L V6 engine. This engine produced 273 horsepower and 251 lb-ft of torque and was paired with a 6-speed automatic transmission. Many owners appreciate the comfortable ride, responsive handling, and the Acura’s reputation for reliability. However, some dislike the less sporty feel compared to the previous generation’s turbocharged model and the somewhat dated technology compared to newer competitors. The switch to a naturally aspirated engine was generally viewed as a step backwards from some performance enthusiasts who preferred the more sporty and exciting engine from the previous generation.

Summary

The 2012 Acura RDX, while generally reliable, has some notable common issues. The engine’s VCM system and transmission’s torque converter are primary concerns, potentially leading to moderate to high repair costs. Electrical glitches with the navigation system and battery drain can also be frustrating. Suspension and interior issues are less common but should be considered. Potential buyers should carefully inspect these areas and review maintenance records to assess the vehicle’s overall condition. While no safety recalls were found, it is important to independently verify this information with the NHTSA website.
