What 2003 Mercedes-Benz SLK230 owners say
Most recent owner complaints, unedited.
My drivers side brake light has been repaired or replaced 11 times. The recall to fix it failed and mercedes wont correct the tail light system. No brake light is extremely dangerous in traffic, in making left turns especially! Braking is the most important light function on any vehicle!
When driving at normal speed the front passenger side wheel locks up. This has happened at 40 MPH (in town) and also 65 MPH (on highway), almost causing me to hit another car and run off the road. Its happens twice for only 3 seconds at a time. The bas, sap and emergency lights all come on at this time.
