Extension is being given because M/B has determined that dimensional variations during engine valve seating may cause the EGR valve to be switched off, and the vehicle may experience a loss of power and enter a limp home mode. The MIL will illuminate and remain illuminated until the vehicle is serviced. When this occurs, the driver may perceive a jerky driving experience while operating the vehicle.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019877-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11019877-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11019877","components":[{"id":"engine","name":"Engine","parent":null},{"id":"exhaust-emissions","name":"Exhaust and emissions","parent":null},{"id":"egr-valve","name":"EGR valve","parent":"exhaust-emissions"}],"codes":[],"topics":[],"vehicles":[{"make":"TIFFIN","model":"CAHABA","year_from":2022,"year_to":2022,"match":null,"vehicle_ids":[]},{"make":"TIFFIN","model":"GH1","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"TIFFIN","model":"WAYFARER","year_from":2021,"year_to":2021,"match":null,"vehicle_ids":[]},{"make":"TIFFIN","model":"WAYFARER","year_from":2023,"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.
