X-TRAIL T33 Lithium Ion Battery
- Defect
- For affected vehicles the lithium-ion battery controller (LBC) on some X-Trail (T33) vehicles may not properly maintain diagnostic robustness. It has been found that these ICs may misdiagnose abnormalities and as a result the system may enter fail-safe mode during driving which restricts motor output and prohibits charging. Under certain conditions a loss of motive power may occur and the vehicle may stop while driving due to the loss of propulsion.
