NHTSA Defect Investigation #EA04028 On May 14, 2004 the Office Of Defects Investigation (ODI) opened a preliminary evaluation (PE04-043) based on consumer complaints alleging that the brake/tail turn signal lamps would not operate properly when either the tail lights were turned on, the brake pedal was depressed, or when the turn signal switch was activated.on September 14, 2004 ODI upgraded PE 04-043 to an engineering analysis (EA04-028).GM states that some brake/tail/turn signal lamp bulbs can prematurely become inoperative due to excessive heat buildup within the bulb sockets.the cause of the excessive heat build up was determined to be a lack of thermal grease placed in between the bulb and the socket. By letter dated October 27, 2004 GM notified NHTSA that it will conduct a safety recall (NHTSA # 04V524) covering all MY 2003 vehicles.GM dealers will inspect the rear lamp bulb socket assemblies and apply thermal grease to them or replace them with new assemblies with thermal grease already attached.model year 2004 and newer vehicles have the thermal grease installed from the factory. The action taken by GM is sufficient to resolve the issues raised by this investigation.accordingly, this investigation is closed.

NHTSA Defect Investigation #PE04043 Complainants allege that the rear turn signals fail to illuminate and do not provide a signal to drivers in following vehicles.ODI has received one report of a crash where the complainant braked and attempted to make a left turn and the following vehicle impacted the complainant's vehicle in the driver-side door.in May 2002, GM's supplier made changes to the bulb socket that included stopping the use of thermal-mastic grease in the bulb socket.GM reports that the grease reduces arcing at the contacts and dissipates heat thus preventing melting of the socket material or burning of the contacts.most of the subject vehicles were produced without grease applied to the bulb socket.in June 2003, GM directed the supplier to resume the use of grease in the socket.GM issued technical service bulletin (tsb) 04-08-42-004A on July 15, 2004 advising technicians to make sure that adequate amounts of grease were added to the bulb sockets on all service parts.ODI will upgrade this investigation to ea 04-028 to further examine the issue.
