During repeated acceleration/deceleration, the emissions control system in the diesel Engine Control Unit (ECU) is unable to prevent sulfur accumulation inside the catalyst due to lack of robustness of the engine control software. This reduces the purification performance of nitrogen oxides (NOx). Therefore, it does not satisfy the regulatory requirement for emissions level.
The Honda CR-V models affected by this recall were manufactured between 2 February 2015 and 23 May 2018.
