2011 Zero S: what breaks, and at what mileage
What breaks on the 2011 Zero S
Only 3 defect reports have been filed with NHTSA about the 2011 Zero S, which is too few to compute mileage percentiles or a risk score. The reports reported other engine problem.

Every reported failure mode
| Failure mode | System | Reports | With reading | 25th | Median | 75th | Per 1,000 | Typical repair | Severity |
|---|---|---|---|---|---|---|---|---|---|
| Other engine problem | engine | 1 | 0 | — | — | — | 14.9 | $300–$4,000 | High |
| Other electrical problem | electrical | 1 | 0 | — | — | — | 14.9 | $250–$2,000 | Moderate |
| Other speed control problem | adas | 1 | 0 | — | — | — | 14.9 | $250–$2,000 | Critical |
Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.
Recalls on the 2011 model year
NHTSA has issued 2 recall campaigns covering the 2011 Zero S, affecting an estimated 117 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.
The campaigns cover service brakes, hydraulic:foundation components:disc:caliper and exterior lighting:brake lights:switch. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.
One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER
268 vehicles 2013-07-30- Defect
- Zero Motorcycles is recalling certain model year 2011 and 2012 S and DS motorcycles. On the affected motorcycles, the front caliper mounting bolts are susceptible to corrosion which could lead to their cracking and possible fracture.
- Consequence
- If a front caliper bolt fractures, the caliper may come loose and interfere with the rotation of the front wheel. This could cause the front wheel to stop suddenly, increasing the risk of a crash.
- Remedy
- Zero Motorcycles will notify owners, and dealers will replace the front caliper bolts. The recall BEGAN ON August 16, 2013. Owners may contact Zero Motorcycles at 1-888-841-8085.
EXTERIOR LIGHTING:BRAKE LIGHTS:SWITCH
450 vehicles 2012-06-29- Defect
- Zero motorcycles, inc. (zero) is recalling certain model year 2011 and 2012 s, xu, and ds motorcycles, model year 2011 mxd, and xd motorcycles and 2012 x motorcycles. The brake light switch at the front brake lever may not activate until significant brake lever travel occurs.
- Consequence
- The brake light may not activate when a moderate amount of front brake is applied. As such, motorists traveling behind the motorcycle may not be alerted when an affected motorcycle is slowing down, which could lead to a possible crash and potential injury or death to the rider.
- Remedy
- Zero will notify owners, and dealers will inspect and, if necessary, replace the front brake system brake-light switch free of charge. The safety recall began on august 3, 2012. Owners may contact zero motorcycles at 1-831-438-3500.
Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.
Every year of the Zero S
Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.
What the reports on file say
The complaints recorded against the 2011 Zero S are other engine problem (1 report), other electrical problem (1 report) and other speed control problem (1 report). With a sample this size these are anecdotes rather than a pattern, and they are shown because somebody looking at this exact car would rather see them than nothing.
Why this page is short
A model year needs about 8 reports before percentiles mean anything, and this one does not have them. Complaint volume tracks how many cars were sold and how long they have been on the road, so a thin page usually means a rare car, a new car, or a car whose owners do not file.
Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
