Recalled: 3,000 Mack Trucks with Cummins ISL G Natural Gas Engines

Mack recalled more than 3,000 trucks fitted with Cummins Westport ISL G natural gas engines. The ISL G engines affected by the defect are exclusively for Mack trucks. The National Highway Traffic Safety Administration’s safety call report says this is due to a problem with the oil supply line.

Cummins began investigating the equipment after receiving numerous customer reports of defects. The company has since halted shipping in order to make reparations and has resumed shipping the engines with improvements.

Engines manufactured between September 2007 and Sept 2015 are the ones affected by the recall. An oil leak may occur if the oil supply line comes in contact with the OEM clear air intake clamp, air fuel control tube, or inlet elbow. If the oil leads near the exhaust manifold, there is a risk of a fire.

Mack truck owners affected will receive their recall notification by the end of November. Dealerships will inspect trucks for the defect and replace the oil lines if necessary.
