2 safety recalls, most serious first
1. Electrical system
What's wrong, in plain English: Wiring, modules, batteries. Short circuits can cause stalls or fires. Honda (American Honda Motor Co.) is recalling certain model year 2013-2015 ST1300PA, 2014-2015 CB500, CBR500, CRF250L, CBR650, CTX700, NSS300, VT750, VT1300, 2015 CB300F, CBR300, CBR600, and 2014-2016 NC700 motorcycles. In the affected motorcycles, sealant may have been incorrectly applied to the starter relay switch, and as a result, the electrical system may have a loss of power.
What could happen: A loss of electrical power may cause an engine stall, increasing the risk of a crash.
The fix: Honda will notify owners, and dealers will replace any affected starter relay switch, free of charge. The recall began on August 31, 2015. Owners may contact Honda customer service at 1-866-784-1870. Honda's number for this recall is JS9 and JT0.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2015 CBR300R.
- Book a repair at any authorized Honda dealer. Quote NHTSA campaign 15V439000 (manufacturer code JS9 and JT0).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-866-784-1870.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
