Consequence: If the starting current limiter overheats, the surrounding components can melt, increasing the risk of a fire.
Remedy: MBUSA will notify owners, and dealers will install an additional fuse in the electrical line to the starter, free of charge. The recall began August 31, 2017. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2017080002.
