2020 Hyundai Venue Battery Problems, Symptoms, Causes and How to Fix

The 2020 Hyundai Venue can experience battery problems like slow engine crank, dimming lights, and electrical accessory issues. Common causes include an old/failing battery, faulty alternator not recharging properly, loose battery connections, or excessive electrical loads draining the battery.

To fix, replace the battery if it fails load testing, check the alternator and charging system, clean battery terminals, and reduce electrical loads when parked. Following proper battery maintenance and driving habits can help prevent future battery drainage issues in your 2020 Venue.

Symptoms

Battery Drain/Dead Battery

• Slow engine crank or no start when trying to start the vehicle
• Dim lights or flickering dashboard lights
• Clicking noise from the starter solenoid when trying to start
• Check engine light turning on due to low battery voltage

Battery Connection Issues

• All electrical accessories and lights suddenly dying, indicating a bad connection
• Corrosion buildup on the battery terminals reducing current flow

Other Symptoms

• Delayed engine crank when attempting to start the vehicle
• Fluid leaks or excessive corrosion around the battery
• Low battery fluid level

Potential Causes

Parasitic Battery Drain

One of the most commonly cited issues is excessive parasitic battery drain when the vehicle is parked and turned off.

• Leaving electrical accessories like lights, radio, USB ports etc. on when exiting the vehicle. The Venue gives a “Battery Discharge Warning” to alert the driver about this.
• Issues with the vehicle’s battery management system not properly shutting off electrical loads when parked.
• Faulty alternator not properly recharging the battery when driving.

Battery Age/Degradation

Like all lead-acid batteries, the Venue’s 12V battery has a limited lifespan of 3-5 years before internal degradation causes it to lose capacity and ability to hold a charge.

Bad Battery Connections

Loose or corroded battery cable connections can prevent the battery from charging properly and cause parasitic drains.

Electrical System Issues

Problems with the vehicle’s electrical system like wiring issues, faulty grounds, or excessive current draws from components can also contribute to premature battery failure.

How to Diagnose Battery Issues in Your 2020 Hyundai Venue?

Here are some tips for diagnosing battery issues in your 2020 Hyundai Venue:

Battery Warning Signs

• Slow engine crank when starting the car, indicating a weak battery
• Electrical accessories like lights dimming or malfunctioning
• Battery discharge warning message on the dash
• Check engine or battery light illuminated on the dash

Testing the Battery

The best way to diagnose battery issues is to have the battery tested by a professional mechanic or at a Hyundai dealership service center. They will perform a battery load test to check:

• State of charge (how charged the battery is)
• Cold cranking amps (ability to start in cold weather)
• Reserve capacity (how long it can run accessories with engine off)

This will determine if the battery needs to be replaced or if there is a charging system issue causing the battery to drain too quickly.

Visual Inspection

• Corrosion buildup on the terminals
• Cracks or swelling in the battery case.
• Loose battery hold-down clamp

Monitoring Battery Voltage

Using a voltmeter, you can check the battery’s resting voltage when the car is off – it should be around 12.6V. Anything under 12.4V indicates the battery may need replacement soon.

How to Fix 2020 Hyundai Venue Battery Problems– Step by Step

Step 1: Diagnosing the Battery Issue

• Check for warning signs like slow engine crank, dimming lights, battery discharge message on the dash, or illuminated battery/check engine light.
• Perform a battery load test to check the state of charge, cold cranking amps, and reserve capacity. This can be done by a professional mechanic or at the Hyundai dealership service center.
• Visually inspect the battery for corrosion buildup on terminals, cracks, swelling, or a loose hold-down clamp.
• Use a voltmeter to check the resting battery voltage when the car is off. It should be around 12.6V. Anything under 12.4V indicates the battery may need replacement soon.

Step 2: Replacing the Battery

5. Locate the battery in the engine bay and disconnect the negative (-) terminal first, followed by the positive (+) terminal.
6. Remove any screws/bolts holding the battery bracket in place and carefully lift out the old battery.
7. Clean the battery tray and terminals if there is corrosion present.
8. Place the new battery in the tray and secure it with the hold-down bracket.
9. Reconnect the positive terminal first, then the negative terminal.
10. After replacing the battery, drive the vehicle for at least 30 minutes or let it idle in ready mode for the same duration to allow the new battery to charge properly.

Repairing 2020 Hyundai Venue Battery Problems: DIY or Professional Help?

DIY Battery Replacement:

• Sense of accomplishment from learning a new skill
• Convenience of doing it on your own schedule

DIY Battery Replacement:

• Risk of improper installation leading to further issues
• Need for proper tools like wrenches, safety gear etc.
• Potential difficulty accessing the battery location
• No warranty on work performed

Professional Battery Replacement

• Expertise of trained mechanics ensuring proper diagnosis and installation
• Use of specialized tools and equipment
• Warranties often provided on parts and labor
• Saves time and effort compared to DIY

Professional Battery Replacement

• Higher overall cost due to labor charges
• Need to schedule an appointment and vehicle downtime

2020 Hyundai Venue Battery Problems Repairing Cost

Replacing the 12V Battery

• A new 12V lead-acid battery for the 2020 Venue typically costs between $129 to $219 from retailers like Every Battery.
• Labor costs to have the 12V battery replaced at a dealership or repair shop would be additional, likely $75-$150 for about 1 hour of labor.
• So, the total cost to replace just the standard 12V battery would be roughly $200-$350.

Alternator Replacement Cost

• If the battery keeps dying due to a failing alternator, replacing the alternator on a 2020 Venue costs between $689-$716 on average, including parts and labor.

Hybrid Battery Replacement

• The 2020 Venue is not available as a hybrid model, so hybrid battery replacement costs do not apply.

However, some general notes on hybrid battery replacement from the sources:

• Hybrid vehicle batteries can cost $2,000-$8,000 to replace, varying by model.
• Hyundai provides a 10-year/100,000-mile warranty on hybrid/EV batteries for its hybrid and electric models.

Preventing Future battery problems in 2020 Hyundai venue

Here are some tips to help prevent future battery problems in your 2020 Hyundai Venue:

1. Avoid Excessive Short Trips
   Taking only short drives of 5-10 minutes does not allow enough time for the alternator to fully recharge the battery. This can lead to the battery discharging over time. Make sure to take your Venue on longer drives regularly to allow proper recharging.
2. Don’t Let the Battery Drain Too Low
   Try to keep the battery charge above 20% as much as possible. Letting it drain below that level frequently can degrade the battery faster. Charge your Venue’s battery every 2-3 days, even if you’re not driving long distances.
3. Minimize Electrical Loads When Parked
   Avoid leaving lights, accessories, or devices plugged in when the car is parked as this will drain the battery unnecessarily. Turn everything off before exiting the vehicle.
4. Park in Shaded Areas
   Excessive heat can accelerate battery degradation. Park your Venue in the shade or a garage whenever possible to keep the battery cooler.
5. Secure the Battery Properly
   Ensure the battery is tightly clamped down and not loose. Vibrations from driving with a loose battery can damage internal components over time.
6. Consider Battery Maintenance
   Check the battery water levels periodically and top up if needed. Clean any corrosion buildup on the terminals. This basic maintenance can extend battery life.
7. Avoid Extreme Charge Levels
   Don’t leave the battery at 100% charge for extended periods and avoid letting it drain down to 0% regularly. Keeping it in the 30-80% range is ideal.

Can I drive my 2020 Hyundai venue with a malfunctioning battery?

No, you can’t drive your 2020 Hyundai Venue with a malfunctioning battery. Driving on a faulty battery can potentially leave you stranded and may even cause damage to other electrical components in your 2020 Venue.
