Recall history

2 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

14V713000 · Exterior Lighting:Brake Lights:Switch

Reported: 2014-11-07 (November 7, 2014)

Hyundai Motor America (Hyundai) is recalling certain 2009-2011 Hyundai Genesis vehicles manufactured April 30, 2008, to November 21, 2010, and 2011 Hyundai Equus vehicles manufactured July 31, 2010, to November 21, 2010. Due to a circuit failure, the stop lamps in the affected vehicles may not illuminate.

Consequence: A following vehicle may not recognize that the vehicle is slowing or coming to a stop if the stop lamps on the vehicle do not illuminate as expected. There is an increased risk of a rear-end crash as a result.

Remedy: Hyundai will notify owners, and dealers will repair the stop lamp switch circuit, free of charge. Hyundai issued an interim notification to owners on January 6, 2015. The recall began on March 23, 2015. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 125.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
