Service campaign SP1045
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Polestar Automotive USA and Polestar Automotive Canada on behalf of Polestar Performance AB, has decided to launch Service Action SP1045: Polestar 3 AWD Torque Vectoring Dual Clutch (TVDC) drain plugs on certain model year 2025 Polestar 3 vehicles. Polestar investigations have identified that the drain plugs for the TVDC may not be torqued properly. As a result, leakage may occur. The corrective action is to check for leakage and replace the drain plugs if they are found to be leaking. NOTE: If no leakage is found, check and torque the drain plug screws according to the instruction. If leakage is found, the drain plug screws are not to be reused and must be replaced. We expect only a small number of vehicles will need to replace the drainplug screws. A total of 2,529 U.S. and 212 Canadian vehicles are affected by this service action.

Polestar Automotive USA on behalf of Polestar Performance AB, have decided to launch Delivery Action DP1048: Polestar 3 Cell modules on certain Model Year 2025 Polestar 3 vehicles. Polestar has identified that one or more cell modules in the high voltage battery have been drained below the allowed voltage level. As a result, these battery cells cannot be charged. The corrective action is to identify any defective cell modules by performing a component test in VIDA. When the test has been executed, VIDA will state which repairs are needed. IMPORTANT NOTE: Any new cell modules that are installed must be scanned with the mVIDA app. All old cell modules must follow the return instructions outlined in Service Journal 1000426. 1 U.S. vehicle is affected by this Delivery Action. |
