- Problem
- BMW of North America, LLC (BMW) is recalling certain model year 2014 i8 vehicles manufactured from May 16, 2014, to September 16, 2014. A bolt used to attach a ground cable between the tank and the vehicle chassis may not have been properly welded during manufacturing.
- Risk
- An inadequate weld of the bolt to the fuel tank could cause a fuel leak. In the presence of an ignition source, a fuel leak could lead to a fire.
- Fix
- BMW will notify owners, and dealers will inspect and replace the fuel tank if necessary, free of charge. The recall began in November 2014. Owners may contact BMW customer service at 1-800-525-7417 or [email protected].

Used 2014 BMW i8 buyer's checklist

- Suspension — 1 owner reports. Drive over bumps and listen for clunks; look for uneven tire wear.
- Mileage to watch. Owners typically reported problems around 24,000 miles; ask what was repaired near that point.
- Hybrid system. Check for hybrid-system warning lights and ask whether the high-voltage battery has been replaced or is still under warranty.
- Before you pay: service records, a history report and an independent inspection.
