Alternator/generator/regulator problems of the 2005 Hyundai Santa Fe

During winter driving in snowstorm wiper control arm on driver's side just fell off - making the vehicle impossible to drive due to snow buildup on windshield. It was later discovered that nut holding that arm got loose and was lost. Second issue was the windshield that developed a crack in the bottom with no obvious reasons - nothing was hit/ vehicle is always driven with care. Dealer refused to fix it under a warranty though it was quite clear that the windshield was defective and crack was getting bigger. 3-rd issue - during wet weather/warm-up the brake light and alternator light are on. Took it to dealer 4 times - they could not find the reason - charging is ok/ brakes are fine - the last time the alternator was replaced with new one, but the lights are still on. 4-th issue - brake caliper on rear pass. Side is sticking that causes a constant noise and early wear of brake pads/rotor on that side - it was replaced twice already and vehicle only has less than 40k miles on it.
