Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2015 i8 over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
BMW of North America, LLC (BMW) is recalling certain model year 2015 i8 vehicles manufactured May 29, 2015, to June 5, 2015. Improperly drilled holes within the Dynamic Stability Control (DSC) hydraulic unit may restrict one or more pistons impairing the DSC functions, including braking.
Risk: Impaired DSC functionality may negatively impact vehicle handling and braking and increase the risk of a crash.
Remedy: BMW will notify owners, and dealers will inspect the DSC hydraulic unit, and replace if necessary, free of charge. The recall began on February 8, 2016. Owners may contact BMW customer service at 1-800-525-7417.
Carmakers sent NHTSA 209 service bulletins and notices that cover the 2015 i8, the latest on Mar 13, 2025. They tell dealers how to fix known issues.
The parts they mention most: electrical system (81), equipment (75), engine and engine cooling (17), equipment adaptive/mobility (16), engine (14).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
