FORWARD COLLISION AVOIDANCE: CRASH IMMINENT BRAKING
Honda (American Honda Motor Co.) is recalling certain model year 2014-2015 Acura MDX 2WD and AWD, RLX and 2014 Acura RLX Hybrid vehicles. In certain driving conditions, the Collision Mitigation Braking System (CMBS) may incorrectly interpret certain roadside objects such as metal fences or metal guardrails as obstacles and unexpectedly apply the brakes.
Consequence
If the CMBS unexpectedly applies emergency braking force while driving, there is an increased risk of a crash.

What the ratings mean
NHTSA gives the 2015 Acura RLX 5 out of 5 stars overall, level with the 5-star median for the 21 comparable 2015 vehicles NHTSA rated in this class.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 9.7% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares
At 23 MPG combined, the 2015 Acura RLX ranks 15th of 23 midsize cars EPA rated for 2015 — 1 MPG short of the 24 MPG median for that group.
That places it in the lower third of its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.
EPA puts annual fuel spend at about $3,300, $750 more than the $2,550 typical for the class. Over five years at 15,000 miles a year that is roughly $16,500, a $3,750 difference against a class-median vehicle.
Tailpipe CO₂ is 381 grams per mile — about 5.7 metric tons over 15,000 miles of driving.
