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.

2007 Mercedes-Benz SLK350 Problems
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.
A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
As a way to increase braking performance, the brake pads and rotors are make of a softer material and may be in need of replacement after approximately 20,000 miles; owners should be vigilant about getting their brakes checked.
The anti-lock brake system (ABS) modulator assembly may fail due to dirty brake fluid. Our technicians recommend a complete brake system flush every two years in order to help prevent this problem.

2007 Mercedes-Benz SLK350 Reviews
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 noisy on the highway but perfect around town. I think the navigation is better in some other cars, it does not have a comprehensive POI dataset. The iPOD connector was expensive and it does not seem to charge my iPOD Nano version 4-5. I also miss that it is a two seat car and I cannot carry friends and family. In summary, if you are looking for a roadster that has a hard-top convertible and head-turning appeal then this car is worth considering.
