Summary
Radiator Voluntary Service Campaign ***** Campaign Summary***** Nissan is committed to the safety, security and satisfaction of our customers and their passengers. Nissan will be conducting a voluntary service campaign in North America on certain MY 2019 Nissan LEAF vehicles to replace the radiator and bolt. Due to a manufacturing assembly issue, that has since been corrected, the radiator may have been damaged during vehicle assembly. An upper portion of the radiator tank may be pierced due to the assembly technician using a bolt that was longer than the design specified bolt. If seepage happens, Long Life Coolant (LLC) level may drop below the electric pump inlet resulting in rising temperature and triggering of the protection logic which will gradually cut motor torque. The vehicle may experience an EV warning light ON and Turtle Mode. ***** What Dealers Should Do ***** 1.
