Set grill to medium-high. Shuck corn. Grill until charred in spots, turning frequently, 10 to 12 minutes. Transfer to a large platter or cutting board and cover with foil. Let stand 5 minutes.
Meanwhile, in a food processor, pulse cilantro, mayonnaise, lime juice, oil, chipotle, garlic and cumin until smooth. Season with salt. Transfer dressing to a large serving bowl.
Cut corn kernels from each cob and add to bowl with dressing, along with feta. Toss to combine.
TIP Corn can be grilled up to 1 day ahead before using in this salad.
