2013 Mercedes-Benz SLK350 ProblemsOil Seepage on Back of the Cylinder Heads
The Mercedes Benz SLK350 may have engine oil seeping or leaking from the back of the cylinder heads. This is commonly misdiagnosed as leaking valve covers.
On the back of the cylinder heads there are three, in total, plastic expansion plugs that plug access ports to the camshafts. These plugs are well known for seeping oil, and leaking if left unattended. The oil will run down the back of the engine and eventually make it to the ground.
Replacement of these three plastic plugs is extremely simple, and should be done as regular maintenance. The recommended interval for replacement is every 60,000 miles.
The power steering reservoir designed for the Mercedes Benz SLK350 commonly leaks power steering fluid causing a screeching sound when turning the steering wheel, especially when the vehicle is stopped. The power steering light may illuminate on the dash for more severe leaks.
This is caused by cracking in the plastic reservoir, or a hardened, brittle seal between the power steering reservoir and power steering pump.
Remediation involves replacing the power steering fluid reservoir, power steering fluid, bleeding the system of air, and replacement of the seal between the reservoir and power steering pump.
2013 Mercedes-Benz SLK350 RecallsThe Passenger Airbag May Not Deploy
The passenger seat cushion contains a sensing device (occupant classification system, or OCS) to determine if a child safety seat is in use on that seat. The system is designed to turn off the passenger airbag when the system senses a child safety seat in use. These vehicles are being recalled because the system may not correctly classify a very light weight person and incorrectly disable the passenger airbag. This would increase the risk of personal injury in the event of a crash. Dealers will replace the passenger seat cushion, including the OCS to correct this concern.
These vehicles are equipped with a new type of A/C refrigerant - R1234yf. Testing has determined that escaping R1234yf refrigerant may ignite under specific conditions. A severe frontal crash may rupture one of the air conditioner refrigerant lines, which can result in a gaseous mixture of refrigerant being released into the engine compartment. The resulting fire could spread to additional combustible materials. Dealers will replace the R1234yf refrigerant with R134a (which is the type that had been used previously) along with new refrigerant lines (hoses) designed specifically for R134a.
