Mercedes Benz SL Class recalls

What is wrong

Mercedes-Benz is recalling certain model year 2013 SL-Class vehicles manufactured from December 19, 2011, through May 31, 2012 originally equipped with R1234yf refrigerant. Daimler AG (DAG), the parent company of Mercedes-Benz, conducted product testing of a vehicle, not sold in the US, but equipped with the same refrigerant. According to Mercedes-Benz, the testing was designed to replicate worst-case conditions expected in a severe frontal crash that would cause a rupture of the air conditioner refrigerant line. A rupture of a refrigerant line will result in a gaseous mixture of refrigerant being released into the engine compartment.

Risk

The testing conducted by DAG determined that the escaping R1234yf refrigerant may ignite under specific conditions. The resulting fire could spread to additional combustible materials.

Remedy

Mercedes-Benz will notify owners, and dealers will replace the R1234yf refrigerant with R134a along with new refrigerant lines (hoses) designed specifically for R134a. The remedy will be provided free of charge. The safety recall began on November 8, 2012. Owners may contact Mercedes-Benz at 1‑800‑367‑6372.

What is wrong

Mercedes-benz is recalling my 2006-2008 m-class, r-class, my 2005-2009 slk-class, my 2005-2008 c-class, my 2003-2004 and 2006-2008 clk-class, my 2003-2008 e-class, my 2004 and 2008 cl-class, my 2008 cls-class, my 2004 and 2007-2008 s-class, my 2003 g-class, and my 2003-2004, 2006 and 2009 sl-class vehicles. A software calibration number (scn) coding received on the affected vehicles during a recent workshop visit was incorrect. Depending on the model year and model affected, the results of an incorrect scn coding can affect a number of vehicle safety and emission functions including the following types of functions: (1) the fuel gauge readings may be incorrect; (2) a stuck fuel-level sensor may not be displayed in the instrument cluster; (3) the obd system may cause the check engine light to illuminate incorrectly; and, (4) the speedometer may be out of tolerance.

Risk

In the event of a vehicle crash, the electrical fuel pump may not receive a crash signal that is required for the fuel pump to disconnect and prevent future fuel delivery as designed.

Remedy

Dealers will recode the scn free of charge. The recall began on august 30, 2008. Owners may contact mercedes-benz at 1‑800‑367‑6372.

Recall number 08V303000 · Recall details

What is wrong

On certain vehicles, the sensotronic brake control (sbc) system may prematurely shift to the hydraulic back-up function mode, due to deterioration of the wiring harness connection, or due to premature failure of the hydraulic pump.

Risk

In the hydraulic back-up mode, the driver has braking power sufficient to stop the vehicle, although greater brake pedal pressure is required and the brake pedal travel will be noticeably longer.

Remedy

Dealers will install a bracket and replacement ground wire to the sbc pump unit on all vehicles free of charge. Additionally dealers will inspect and replace the sbc pump unit in sl vehicles produced during a limited production period. The recall began on august 8, 2005. Owners may contact mercedes-benz at 1‑800‑367‑6372.

Recall number 05V133000 · Recall details

What is wrong

On certain vehicles, the electronic monitoring system of the sensotronic brake control (sbc) is designed to monitor the pressure gradient within the high pressure line of the brake system. If an unacceptable pressure gradient is detected, the system will switch, as it is designed to do, into the hydraulic function mode.

Risk

If vehicles are not routinely serviced and have extremely high mileage combined with a high number of brake actuations, or a high brake actuation frequency, the pump motor of the sbc may run out of permissible tolerances, thereby triggering the hydraulic function mode.

Remedy

Dealers will inspect the sbc hydraulic unit, replacing it if necessary. The recall began on october 21m 2004. Owners should contact mercedes-benz at 1‑800‑367‑6372.

Recall number 04V296000 · Recall details

What is wrong

Vehicle description: passenger vehicles. Corrosion of the electrical ignition filament of the air bag gas generator module can occur if the vehicle is operated in areas of frequently high humidity.

Risk

Corrosion of the ignition filament can result in the driver's air bag being deployed unintentionally.

Remedy

Dealers will replace the driver's air bag module.

Recall number 99V327000 · Recall details

What is wrong

If one of the headlamp wiper arms becomes misaligned, the wiper balde can lodge in the groove under the headlamp. If the washers are activated with the wiper blade in the misaligned and lodged position, the washer pump will run continuously expelling all available fluid.

Risk

Pump operation in the absence of fluid can cause the pump to overheat and cause a vehicle fire.

Remedy

Dealers will replace the headlamp washer pump on these vehicles.

Recall number 96V175000 · Recall details

What is wrong

The drive belt pulley on the engine can develop fatigue cracks in the metal and break. If the drive pulley breaks, the car would not have engine cooling, battery charging, and/or power steering.

Risk

Loss of these systems can cause the car to over heat, lose power from the battery, and loss of control of the car increasing the potential for a vehicle accident.

Remedy

Dealers will replace the engine crankshaft damper-pulley on these vehicles.
