I have same issue in upstate NY with a 2004 with 120,000 miles, purchased new. Golfball sized hole rusted into right side subframe that holds engine and suspension. Quoted $1400 to fix. Called Nissan Corp and they will not pay for repair. You can see the hole if you turn the wheel all the way right and look into the right side wheel well. I’m trying to decide if its worth the repair price to keep vehicle going up to 140,000 miles. But other things are also going bad. Sliding door won’t open from outside, dash LCD screen (fuel gauge area) occasionally blanks out.
