NHTSA Defect Investigation #DP09002

REAR LAMP ILLUMINATION: Exterior Lighting:Back Up Lights**

CLOSED

no recall issued

** This defect investigation is filed under 5 related vehicle components.
2003 BMW 325I -- In March 2009, the Office Of Defects Investigation (ODI) received a petition from mr. Mark peters requesting an investigation of rear lamp failure in model year 2002-2005 BMW 3-series vehicles. An information request letter was sent to BMW in April 2009, and ODI received BMW's response in June 2009. The tail lamp assembly contains lighting for the brake lamps, tail lamps, and turn signals. A technical service bulletin (tsb) was issued by BMW in January of 2007 instructing service technicians to examine an 8 pin electrical connector for heat-related damage and to incorporate additional ground wiring to the connector. Complainants have alleged that significant thermal damage to the connector and associated ground wiring has occurred. This condition can result in intermittent or total loss of all lighting (brake, tail, and turn signal) for the effected rear lamp assembly. ODI will open a preliminary evaluation to further examine this issue including further evaluating BMW complaints and related warranty data. Investigation was initiated on April 08 2009. Closed on August 06 2009. For detailed information & supporting documents, see the official NHTSA page concerning investigation #DP09002 »

NHTSA Defect Investigation #EA09019

REAR LAMP ILLUMINATION: Exterior Lighting:Brake Lights**

OPEN

possible recall

** This defect investigation is filed under 4 related vehicle components.
2003 BMW 325I -- The outboard rear light assembly consists of a turn signal lamp, a tail lamp and a brake lamp. Failure of the light assembly ground circuit results in loss of all three lamps. BMW submitted complaint and warranty information showing a significant number of rear lamp assembly failures due to an open ground connection at the eight pin connector of the light assembly. This results in the loss of the rear turn signal. Overheating of the ground circuit electrical pin, possibly due to increased resistance and or high current flow, is indicated in some failures. Additionally BMW issued a technical service bulletin (tsb) sib-630306 in February 2007 to address the condition by adding supplementary ground wiring to the tail lamp assembly. The additional ground wire added by the procedure reduces the current flow at the eight pin connector. ODI is opening this ea to further investigate the issue. Investigation was initiated on December 18 2009. For detailed information & supporting documents, see the official NHTSA page concerning investigation #EA09019 »

CLOSED

no recall issued

** This defect investigation is filed under 4 related vehicle components.
2003 BMW 325I -- ODI has received complaints from consumers stating that their tail light assembly is not properly illuminating. The tail light assembly consists of a turn signal lamp, a tail lamp and a brake lamp. The complainants have indicated that the issue is with an 8 pin connector and associated ground wiring. These components are allegedly overheating and melting due to excessive electrical current that runs through the system. BMW issued a technical service bulletin (tsb) sib-630306 on February 2007 to address the condition by adding supplementary ground wiring to the tail lamp assembly. ODI is upgrading to an ea to further investigate the issue. Investigation was initiated on August 07 2009. Closed on December 22 2009.
