Detroit Diesel Corporation Settlement
Detroit Diesel Corporation Settles For $5,625
In January 2022, the California Air Resources Board (CARB) reached a settlement with Detroit Diesel Corporation (DDC), based in Detroit, Michigan, for DDC’s violation of the State’s “Procedures for Reporting Failures of Emission-Related Components” Regulation (Cal. Code Regs., tit. 13, §§ 2141 et seq.). The full penalty amount of $5,625 will be deposited into CARB’s Air Pollution Control Fund, which provides funding for projects and research to improve California's air quality.
CARB’s Enforcement Division was made aware of the issue during a Truck & Engine Manufacturers Association Compliance Workshop in 2018, wherein CARB’s Heavy-Duty Engine (HDE) program presented that while the overall HDE warranty claims rates were improving, individual component failures persisted, resulting in high warranty claims rates. CARB performed an investigation into the timeliness of various HDE manufacturers’ reporting of emission-related component failures to CARB’s Field Operations and Warranty Section. The investigation proved DDC to be in violation for one Emission Warranty Information Report, submitted later than the Procedures for Reporting Failures of Emission-Related Components regulation allow. DDC has diligently cooperated with CARB throughout the investigation and further understands the importance of timely reporting of warranty reports.
