THE VOLVO Group has detected that an emissions control component used in markets with stringent emissions standards is degrading more quickly than expected, reducing its ability to convert NOx as efficiently as intended, which in turn could cause the engines or vehicles to exceed emissions limits for NOx.
The investigation so far indicates that the degradation does not seem to affect all vehicles and engines in the same way and to the same extent. The company is now in the process of informing the appropriate authorities in various markets and beginning discussions regarding remedial plans.
The degradation of the component does not pose a product safety issue, says Volvo nor does it negatively affect vehicle or engine performance in areas other than emissions control. The degradation is a result of a materials issue that occurs over time. All engines and vehicles equipped with the component meet emissions limits at delivery, the truck manufacturer insists.
Volvo is not yet able to estimate the volume of engines or vehicles that may need to be addressed. Consequently it is not possible to assess the financial impact at this stage; however the cost to redeem the issue could be material, said a Volvo Trucks spokesman.
