2014-2015 Acura MDX, RLX Recalled For Faulty Collision Avoidance Systems

June 10, 2015

Well, this is curious: a day after we reported on an investigation of the 2014 Jeep Grand Cherokee's automated braking system, the National Highway Traffic Safety Administration has announced a recall of select 2014-2015 Acura MDX and RLX models for the same problem.

According to NHTSA, the flaw on the MDX and RLX lies with the Collision Mitigation Braking System, which was manufactured by Fujitsu. Per the bulletin:

"In certain driving conditions, the Collision Mitigation Braking System (CMBS) may unexpectedly activate while operating the vehicle. In rare cases, the system may interpret certain roadside objects, such as metal fences or metal guardrails, as obstacles and apply emergency braking through the CMBS." 

Acura's parent company, Honda, has received at least two complaints in Japan about the issue, and the automaker was able to recreate it in lab settings. The fix involves a software update for the braking system, which will be applied free of charge.

The recall affects the following models:

  • 2014-2015 Acura MDX
  • 2014-2015 Acura RLX
  • 2014 Acura RLX Hybrid
