STOP LAMP SWITCH FAILURE
NHTSA Preliminary Evaluation PE09003 - closed, opened 2009-01-14 and involving the HYUNDAI HYUNDAI.
NHTSA investigation PE09003 is a Preliminary Evaluation opened on 2009-01-14 and currently closed. The subject of record is HYUNDAI HYUNDAI, which places this file inside the Office of Defects Investigation queue for HYUNDAI. Latest activity on this investigation was logged on 2009-04-24 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE09003 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "BY LETTER DATED APRIL 15, 2009, HYUNDAI NOTIFIED THE AGENCY THAT IT WILL CONDUCT A SAFETY RECALL (NHTSA RECALL NUMBER 09V122) TO REPLACE THE STOP LAMP SWITCHES ON MANY OF ITS MODEL YEAR 2005-2008 VEHICLES. SEE RECALL 09V..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related HYUNDAI files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
BY LETTER DATED APRIL 15, 2009, HYUNDAI NOTIFIED THE AGENCY THAT IT WILL CONDUCT A SAFETY RECALL (NHTSA RECALL NUMBER 09V122) TO REPLACE THE STOP LAMP SWITCHES ON MANY OF ITS MODEL YEAR 2005-2008 VEHICLES. SEE RECALL 09V122 FOR A COMPLETE LIST. THE AGENCY OPENED ITS INVESTIGATION BASED ON FIVE COMPLAINTS OF STOP LAMP FAILURE ACROSS SEVERAL 2007 HYUNDAI MODELS. THE AGENCY ALSO RECEIVED EARLY WARNING (EWR) REPORTS ON THIS ISSUE. MOST OF THOSE FAILURES WERE TRACED TO THE IMPROPER OPERATION OF THE STOP LAMP SWITCH THAT CONTROLS STOP LAMP ILLUMINATION. A MALFUNCTIONING STOP LAMP SWITCH CAN CAUSE THE VEHICLE'S BRAKE LIGHTS NOT TO LIGHT DURING BRAKING, OR ALTERNATIVELY, IT CAN CAUSE THE BRAKE LIGHTS TO STAY LIT EVEN WHEN A DRIVER TAKES THE FOOT OFF THE BRAKE PEDAL. FAILURE OF THE STOP LAMPS TO ILLUMINATE PROPERLY CREATES THE HAZARD OF REAR END COLLISIONS WHEN DRIVERS FOLLOWING THE SUBJECT VEHICLE DO NOT RECOGNIZE THAT THE VEHICLE IS SLOWING OR STOPPING. HYUNDAI REPORTED ONE CRASH INCIDENT (A FRONTAL IMPACT), WITHOUT INJURY, THAT WAS ALLEGED TO HAVE BEEN CAUSED BY THIS DEFECT. THE AGENCY REVIEWED THE INCIDENT AND CANNOT CONCLUDE THAT IT IS RELATED TO THIS DEFECT. THERE ARE OTHER POTENTIAL PROBLEMS RELATED TO FAILURE OF THE STOP LAMP SWITCH: FAILURE OF THE CRUISE CONTROL TO DISENGAGE, INTERFERENCE WITH PROPER FUNCTIONING OF ANTILOCK BRAKES AND ELECTRONIC STABILITY CONTROL, AND INABILITY TO MOVE THE GEAR SHIFT LEVER OUT OF PARK POSITION. BASED ON THE ABOVE SAFETY RECALL, THIS INVESTIGATION IS CLOSED.
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
