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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034498-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11034498-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11034498","components":[{"id":"steering","name":"Steering","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ROSENBAUER","model":"AERIAL","year_from":2019,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"ROSENBAUER","model":"AVENGER","year_from":2019,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"ROSENBAUER","model":"COMMANDER","year_from":2019,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"ROSENBAUER","model":"WARRIOR","year_from":2019,"year_to":2024,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
