Rosenbauer service campaign TSC26001
Rosenbauer filed this with NHTSA as a service campaign dated Jul 15, 2026, received Jul 5, 2026, about the steering. It names 22 model years (2019–2024). 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
Source: NHTSA's summary of the manufacturer's communicationSubject: The power steering cooler may begin to leak on the low-pressure side of the system. This fault will need to be inspected and corrected if any seepage is present Problem: Power steering cooler fittings have an inconsistent machined edge; this edge prevents the O-ring from sealing resulting in a slow seepage. Applies To: Certain 2019-2026 Rosenbauer trucks have been flagged as possible candidates. Rosenbauer will be supplying a list to service partners and notifying customers. Assistance Needed: Dealers to follow the Technical Service Campaign instructions and inspect the listed candidates for faulty power steering coolers. If known leaks are present, submit a CRM ticket with an image of the leaking cooler fittings. Resolution: If this problem is found, a replacement Setrab cooler with higher quality standards and machining will be supplied at no cost to customers. This correction does not change the connected hoses and does not require a full power steering drain.
