It is recommended that the alternator be examined at the same time as the battery replacement.

Driving with all dash lights illuminated can be a concerning experience. In most cases, this is due to an alternator malfunction, while a dead battery is the second most likely cause. Electrical shorts in the wiring may also lead to this issue, though less likely. It is essential to have any cases diagnosed and repaired as soon as possible if you encounter such a problem.

  1. I recently had the opportunity to test drive the Hyundai Tucson All Warning Lights On, and I must say that I was quite impressed. The warning lights system provided me with detailed information about the car’s condition in real-time, giving me peace of mind when it came to safety while driving. Additionally, its performance was smooth and efficient, as well as its modern design. Overall, I would highly recommend this vehicle to anyone looking for dependable and high-performance features.

  2. I just had this happen to me (2016 Hyundai Tuscon)when I was 60 miles from home. It started with just one warning to check AEB system, then every warning light came on, I made a few stops and then i could no longer open rear hatch, car would no longer shift out of park (though after shutting car and turning on again, I was able to get into gear), I drove home, biting my lip the whole way, but couldn’t afford a 60 mile tow! Speedometer didn’t work, I had no lights, no turn signal, and prayed my power steering didn’t go out along the way!! Mechanic ultimately said it was the vacuum pump that caused the problem. I hope he’s right and that will fix problem ($1000 fix!)
    **NOTE: there was a technical bulleting regarding this (2018), Hyundai dealers were instructed to seal pump on any cars brought in. Records show this had been done on my car in 2019

  3. All warnings lights come on while driving, speedometer doesn’t work, fuel gauge goes up and down. A/C stops working and more.

    • It seems like your Hyundai Tucson is experiencing quite a few electrical issues, which might be connected. When multiple systems fail at once, it often indicates a problem with a common point of failure such as the electrical system or the vehicle’s computer. Here are a few things you can consider:

      • Battery and Alternator: Check the condition of your car’s battery and alternator. These components are critical for the electrical systems in your car. If they are malfunctioning, they could be causing the issues you’re seeing. A weak battery or failing alternator can cause erratic behavior in many systems, including the warning lights, gauges, and air conditioning.
      • Fuses and Wiring: Check the fuses related to these systems, and look for any blown fuses. Additionally, you might want to inspect the wiring harnesses for any sign of damage or corrosion that could be causing intermittent connections.
      • Vehicle’s Computer (ECU): The Engine Control Unit (ECU) or the car’s computer controls most of the electrical systems in the car. If the ECU is malfunctioning, it could send erroneous signals to various components of the car, causing them to behave irregularly.
      • Ground Connections: A faulty ground connection can cause various electrical systems to malfunction. Ensure that the ground connections are clean, secure, and corrosion-free.

      In this situation, it would be highly advisable to take your vehicle to a professional mechanic or a Hyundai dealership. The nature of the problem indicates that specialized diagnostic equipment may be needed to pinpoint the exact cause of these issues. Please don’t ignore these signs as they might lead to more severe problems if not addressed promptly.
