Official recall record

Truck - Med. & H.D. recalled by MACK (ref 70182)

What the authority reported

On certain vehicles equipped with Cummins ISL engine, the exhaust pipe may disconnect from the muffler/catalyst. If this occurs on a twin-steer configured vehicle where the vehicle is operated from the right side, the operator may be exposed to carbon monoxide, which could result in asphyxiation or carbon monoxide poisoning. Correction: Dealers will install a different length exhaust flex pipe and a turbocharger outlet pipe to reduce rigidity of the exhaust to address this condition.

What to do

Follow the instructions in the official notice — recall remedies (refund, repair, replacement, or disposal) are defined by the issuing authority and the responsible business, and they differ per recall. Do not rely on summaries, including this one.
