Mercedes-Benz SLK350 cracked crankshaft requiring full replacement due to common manufacturing issues on Mercedes-Benz SLK350

Some Mercedes-Benz SLK350 owners report experiencing engine performance problems related to crankshaft position sensor failures. Additionally, common issues within the SLK series include hydraulic cylinder leaks, cracked seals, stiff hinges, and brake problems. Reliability concerns have been noted, particularly with the 2016 model, where owners should assess the risk of major repairs within the next 12 months. When a cracked crankshaft occurs, it may be linked to slow oil pressure buildup, wear in the timing chain and components, and balance shaft gear wear. Furthermore, drivers have reported cracks in the thrust link bushing of the front suspension system, which can impair the suspension's ability to absorb road vibrations. Addressing these issues promptly is crucial for maintaining the vehicle's performance and safety.
