Acura has recalled two models because the automatic emergency braking systems can malfunction and put the vehicles at risk of a collision.
The recall involves just under 48,000 MDX SUVs and RLX sedans worldwide from the 2014 and 2015 model years and shows how even sophisticated safety technology can be prone to real-world glitches.
Acura’s “Collision Mitigation Braking System” uses radar to scan conditions in front of the vehicles. If it determines the vehicle might hit an object, it automatically applies the brakes, slowing the vehicles to reduce damage and injuries.
In the recalled vehicles, the system can become confused and step on the brakes when it detects another vehicle accelerating in front while simultaneously driving along an iron fence or metal guardrail, according to Honda, the maker of Acura. The problem first surfaced in Japan in November of 2013 when an SUV braked for no reason and caused a rear-end collision.
