 In its letter dated october 28, 2005, mercedes-benz usa stated that it would conduct a safety recall to remedy defective brake lamp assemblies in model year 1998 through 2004 mercedes benz slk vehicles.the base of the brake lamp socket can be subject to thermal deformation over time.this deformation can cause movement in the socket-to-bulb connection, which may lead to a loosening of the electrical contacts in the socket, and failure of the bulb to illuminate.all rear lamp modules (which contain brake, turn signal, tail and backup lamps) will be replaced with redesigned rear lamp modules with a more heat resistant material and enhanced socket holder design to withstand the heat inside the rear lamp module.see nhtsa recall no. 05v505 for more information.

 Re: nhtsa campaign # 05v-505. the manufacturer indicated in a letter to nhtsa that it would start owner notification no sooner than second quarter of 2006. it is now third quarter 2006 and when asked, the manufacturer still says there are no active recalls on this vehicle. i feel that the manufacturer needs to provide an updated schedule for compliance with this recall campaign. *jb

 Brake lights burn out frequently on my 1999 mercedes slk 230. light sockets burn with discoloration and plastic melts at the socket and circuit board on the rear of the taillight. it is very difficult to remove the burned socket from the fixture. the intent of the design is to use finger pressure to twist the socket out. due to the melting it requires the use of a wrench that then damages the socket sometimes to an unusable condition requiring replacement at owner cost. dash bulb out warning light is too dim to notice and hidden from view behind the steering wheel. bulb out warning light illuminates sometimes when there are no lights burned out so this makes it useless to determine what bulb is actually out if any. my car was in the mercedes shop for 30 days and returned to me with the comment ⿿condition could not be duplicated⿝ in regards to the taillight. all they had to do is remove it to see the burnt condition but they chose to ignore the problem. i have had to purchase a handful of sockets to keep on hand as they need replacing every month or so. i even purchased a new set of taillights, the entire housing and new sockets thinking this would solve the problem but they burned out a month later. i have turned the taillight over to nhtsa. *jb

 I have a mercedes-benz 1999 slk 230. the bulb socket for the brake light lamps in the rear light assembly keeps failing as the contacts do not make proper contact during vibrations leading to electric arcing at the contacts. the arcing builds up deposits that break the connectivity leading to inoperative rear brake lights (a safety issue) and heats up the area melting the plastic and fusing the socket to the assembly. there is a potential fire hazard here because of the open electric arcing. related to open case pe05051. the bulb itself does not fail as currently described in that open investigation but the contact does. mb's solution is to just replace the whole assembly with the same defect which fails again after a while. *jb

 I own a 1999 mercedes benz slk230. on december 18, 2004 i took the car into the dealership (friendly mercedes benz in wappingers falls, ny) due to a brake light problem. dealer informed me of a known problem with the light overheating causing the assembly to melt and short out the light. mercedes would not cover the replacement cost of $269.50. regardless of cost, the potential for a fire evidently exists. i read yesterday that an investigation has been opened in this very matter so i thought i'd provide yet another example of this type of occurrence. *nm

 There is a defect in 1998 - 2001 mercedes benz slk model cars tail lights and brake lights. the socket which houses the bulbs does not provide sufficient pressure to maintain electrical contact. the result of this is burned conctats, melted bulb housings and burned out tail and brake lights. this can lead to a fire or an accident in the event of failure. this defect has been reported by hundreds/thousands of slk owners to the manufacturer. the maufacturer refuses to acknowledge this defect and will do nothing to correct it if the vehicle is out of warrenty. the defect, if discovered by the owner prior to warranty expiration is corrected, but if the defect is not discovered in warranty the manufacturer will do nothing to correct it. subsequent (post 2001) models have had this defect corrected but the pre 2001 vehicles still have this defect.
