Recall 19V122 covers 24,173 International Prostar and Lt trucks for cracking exhaust brackets. Repair is free at any franchised International dealer.
International is recalling 24,173 2016-2020 Prostar and Lt sleeper cab models because the rear exhaust hanger bracket can crack and lead the forward bracket to crack. If both brackets crack, the exhaust tail pipe can detach from the vehicle and become a road hazard, which increases crash risk; International dealers will complete the free repair.

What's wrong?
The exhaust tailpipe on affected 2016-2020 International Prostar and Lt sleeper cab trucks is held in place by hanger brackets. These brackets support the pipe as the truck moves, absorb vibration, and keep the exhaust system aligned on the right side behind the aftertreatment device. When the brackets do their job, the tailpipe stays mounted and clear of surrounding parts.
On these trucks, the rear exhaust hanger bracket was made with insufficient material strength for this application. The rear bracket can crack first, which puts added load on the forward hanger bracket. If both brackets crack, the exhaust tailpipe can drop out of position and detach from the truck. International corrected production with a redesigned hanger bracket.
During a pre-trip inspection, the operator can notice a cracked rear exhaust pipe hanger or a tailpipe sitting lower than it should. A tailpipe that has dropped out of position is the warning sign to report before the truck is driven farther.

What's the safety risk?
An exhaust tail pipe that detaches while driving can become a road hazard and increase crash risk for nearby traffic. During inspection, look for a cracked rear exhaust pipe hanger or a tailpipe dropped out of position. If you see either condition, call the dealer before the next trip. Repair is free at any franchised International dealer.
What should I do?
- Check your VIN to confirm your 2016-2020 International Prostar or Lt is included in this recall.
- Contact a franchised International dealer to schedule the free exhaust hanger bracket repair and tailpipe damage check for the cracked-bracket issue that lets the tailpipe detach.
- Bring the recall notice if International mailed one. If not, reference recall number 19V122 and International recall 19501 when you call.
- Drive with extra space until the repair, and pull over safely if the exhaust tailpipe loosens or drags.
What happens at the repair
At the dealer, an International technician replaces the rear exhaust hanger bracket. The technician also checks the forward bracket and exhaust tailpipe, then replaces any forward bracket that is cracked and any tailpipe that is damaged. Parts and labor are covered under the recall. If you already paid for the same exhaust bracket or tailpipe repair before the recall notice, International's reimbursement plan applies. Follow the reimbursement instructions in the owner notice, and keep repair invoices or payment records for the claim.
