Mercedes-Benz SLK350 Problems
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.
High mileage or older vehicles commonly develop leaks from the differential seals and/or cover. Our technicians recommend a complete reseal of the differential unit whenever these leaks are repaired.
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.

Mercedes-Benz SLK350 Recalls
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 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.

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.
