Some MyLift systems have been observed to contain a pitted pressure switch contact, causing the system not to function as designed. Reliable failure of the component has not been confirmed, and full manual control of the axle lift functions remains intact. However, Polar?s commitment to reliable products leads us to trade out existing MyLift assemblies with an upgraded version.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10119396-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10119396-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10119396","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"POLAR TANK","model":"MC 331 TANK TRAILER","year_from":2016,"year_to":2016,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
