“COMPONENT THAT FAILED: A high-pressure fuel injector (cylinder 2). The failed injector and engine wiring harness are available for inspection on request. The vehicle is currently at an authorized dealer. WHAT HAPPENED: While driving at approximately 35-45 mph under light throttle in normal traffic, the engine began misfiring without warning. The misfire worsened rapidly over several seconds and the engine ran roughly enough that I pulled off the road. A strong burning smell was present immediately afterward. The vehicle has continued to misfire since. …”
