Automatic headlight system causes the vehicle headlights to turn on and off during daylight conditions. The LCD display in the dashboard also dims to the point that the information presented cannot be read. This typically happens on bright, sunny days with a clear sky. Vehicle has been to the dealership in excess of seven times where they’ve made multiple attempts to repair it. The light sensor behind the windshield has been replaced. The body control module has been replaced. The technician also tried to make modifications to the light sensor, but the problem persists. There are a number of other instances of this exact issue involving Hyundai Tucsons, Santa Fe. and Santa Cruz vehicles shown on the NHTSA site, and also when searching other sites online. Dealer technician has repeatedly documented that the problem exists. Dealer tech reported that the Tech at the Hyundai helpline suggested that the auto headlight feature not be used as a resolution. While not a solution under any conditions, even with auto headlight feature turned to off, the dashboard displays continue to dim during the day. The flashing headlights represent a serious safety issue as when following another vehicle, that driver may misinterpret the flashing headlight problem as an aggressive gesture and trigger a road rage type response. The call taker I spoke with at Hyundai when I opened a customer service case said that he personally had that very issue with another driver due to flashing headlights.
