Summary
The Mercedes-Benz SLK Class has 8 recalls spanning 1998 to 2016, with the most serious affecting 2016 models where incorrect electronic stability program software can leave residual hydraulic pressure in the brake system after automatic braking, compromising brake response.
Also on 2016 models, rear tie rod lock nuts can work loose and shift the rear wheel alignment, reducing steering control. A separate electrical issue on 2016 vehicles involves a misconnected backup power feed for the ignition switch: if the main battery fails while the transmission is out of park and the electronic parking brake is not engaged, the transmission loses the ability to shift into park. There is also a compliance recall on 2016 models where low-beam headlamp aim can fall outside the required range, reducing road illumination. On 2012 models, the passenger seat occupant classification sensor can misread its occupant in either direction: it can mistake a child seat for a small adult and leave the front passenger airbag armed when it should be off, or mistake a small adult for a child seat and suppress the airbag when it should deploy in a crash. Going back to the earliest production years, 1998 models have brake light sockets that can deform from bulb heat, loosen the electrical contacts, and cause the brake lights to stop illuminating. The 2000 model year has a compliance issue where the owner's manual omits proper headlamp aiming instructions.
