IC BUS service campaign 24111
IC BUS filed this with NHTSA as a service campaign dated Dec 9, 2024, received Oct 3, 2024, about the engine — 2 documents under this number: Coolant Hose Reroute. It names 3 model years (2022–2024). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says

Added image showing correct installation of parts for the overall cabin heater system. Revised steps and images throughout the document for consistency and clarity. DEFECT DESCRIPTION: Certain IC Bus® Electric CE Series buses may have incorrect coolant hose routing for the cabin heat which may cause coolant to leak from the cabin heat surge tank overflow hose.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.
Model years it names
Source: as the manufacturer filed themAlso filed against: 2023 IC BUS EV; 2022 IC BUS Evsb; 2024 IC BUS Evsb.
None of these model years has a page on this site (it covers EPA-certified cars, trucks and SUVs from 2016), so the bulletin is listed here on its own.
Common questions
Source: NHTSA, 49 CFR 579.5Is IC BUS 24111 a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls.
Is the 24111 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does 24111 cover?
The manufacturer filed it against 3 model years: 2023 IC BUS EV, 2022 IC BUS Evsb, 2024 IC BUS Evsb. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
