Specific to the 2017 model year, there have been recalls related to potential fuel leakage, which could increase the risk of a fire. Other reported concerns include issues with the adaptive headlights and occasional sensor malfunctions. Long-term reliability concerns generally center around the continued functionality of the hardtop and air suspension systems, as these are complex and expensive to repair. Regular maintenance and addressing issues promptly can help mitigate some of these concerns. It is crucial to check the vehicle history report for any prior recalls or service records related to these common issues.

The 2017 Mercedes-Benz SL-Class is ideal for buyers seeking a luxurious and powerful roadster with a retractable hardtop.
