Steering is the standout concern for the 2014 Acura RLX, accounting for the largest share of complaints by a wide margin. Owners frequently report sudden loss of power steering while driving, often accompanied by the steering wheel pulling left or right and a cluster of warning lights illuminating at once, lane departure, forward collision, all-wheel steering, and power steering indicators together. Many of these reports point to the rear toe actuator in the Precision All-Wheel Steer system, where failure leads to steering instability and unpredictable handling, particularly during cornering. Suspension complaints, the second-most-reported category, are closely tied to the same PAWS hardware. A smaller number of owners describe the vehicle entering a reduced-power mode on the highway, during which the car decelerates sharply and multiple dashboard warnings appear simultaneously, leaving the vehicle unable to accelerate normally until towed.

Crash-Related
By System
The 2014 Acura RLX has 8 recalls, the most serious being loose rear suspension bolts that can reduce steering control and a collision mitigation braking system that can apply emergency braking unexpectedly when it misreads metal guardrails or fences as obstacles.
On the mechanical side, the fuel pump can fail and stall the engine while driving. The driver and front passenger seatbelts may not extend or retract properly in cold temperatures, reducing their ability to restrain occupants in a crash. Two recalls address the headlights: a reflective film inside the headlight housing can delaminate and reduce light output, dimming visibility at night. There is also a separate wiring issue where an incorrect sub-harness was installed on the right headlight, which may affect that light's output as well.
