2013 Zero FX
Zero Motorcycles is recalling 128 of its 2013 Zero FX and 2013 Zero XU electric motorcycles.
The reason? A manufacturing defect with the sealant material in the battery may allow water to penetrate the battery. When this happen, corrosion of the li-ion cells will couls result in a rapid temperature increase and off-gassing of the cells' electrolyte, which may cause a burn to the rider.
Here are more details straight from the NHTSA's website:
RECALL Subject: Water may Penetrate Battery resulting in Leakage
SUMMARY: Zero Motorcycles Inc. (Zero) is recalling certain model year 2013 FX motorcycles manufactured January 28, 2013, through May 21, 2013; and model year 2013 XU motorcycles manufactured January 16, 2013, through May 20, 2013. A manufacturing defect with the sealant material in the battery may allow water to penetrate the battery and contact the cells.
CONSEQUENCE: Water penetration into the battery may lead to corrosion of the cells, possibly resulting in a rapid temperature increase and off-gassing of the cells' electrolyte which may cause a burn to the rider.
REMEDY: Zero will notify owners and dealers will replace the battery modules, free of charge. The recall is expected to begin in late June 2013. Owners may contact Zero motorcycles at 1-888-786-9376.
Interesting is the number of bikes affected (128). This could well be the total production of these two models in 5 months.
Noteworthy too is that the Zero MX, which has ZF2.8 or ZF5.7 battery packs (same as Zero FX and Zero XU), isn't affected by this recall.
