Mercedes-Benz SLK350 Problems

Rough Shifting of Automatic Transmission

Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.

Check Engine Light Due to Faulty Camshaft Adjuster Solenoid

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Oil 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.

Driver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments

The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag module free of charge to resolve the concern.

Front Passenger Seat Air Bag May Not Deploy Properly

In a crash that deploys vehicle air bags to protect occupants, the passenger seat air bag may not deploy, increasing risk of injury. Dealers will replace the passenger seat air bag free of charge to resolve the problem.

The 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.

Mercedes-Benz SLK350 Reviews

I've been driving the 2012 SLK350 since late June 2011. Overall, it's a great car. I love its performance and handling. There has been one annoying mechanical deficit though. A month after I took delivery of the vehicle, it started sounding like a helicopter was hovering about 10 feet overhead. Turns out a fuel pump valve was bad. So, after waiting 3 weeks for the part to arrive from Germany, t...
An excellent convertable. The hard top convertible works well and provides and excellent hard-top driving during off season driving. The car has been a very good value for me. Gas milage has been about 18-20 MPG around town. Despite being small, the trunk holds two sets of golf clubs (carry bag size) but you cannot also put the top down. My only complaints are that it is a roadster, so it is no...
I have to make a trip almost every month for one or other electrical problem. Fix one, and then another one shows up in 5-10 days. Nothing major, mostly turn signals, fog lights, seat belt sensors.
