An emissions control component in Volvo trucks may degrade more quickly than expected, leading to excessive emissions of nitrogen oxides, AB Volvo announced on Tuesday. The emissions control component degrades differently in different vehicles and engines, which means Volvo is unable to name precisely which and how many vehicles are affected. Remediation plans are now underway.
“The degradation of the component does not pose a product safety issue, nor does it negatively affect vehicle or engine performance in areas other than emissions control,” Volvo AB wrote in a press release.
The largest volume of engines which could potentially be affected have been sold in North America and Europe.
Volvo AB was quick to clarify that “All engines and vehicles equipped with the component meet emissions limits at delivery,” perhaps wary of the scandal brought on by Volkswagen’s manipulation of diesel emissions.
