The 2017 Lincoln MKZ is a luxurious sedan known for its smooth ride and advanced features. However, like any vehicle, it can experience battery problems. This guide will delve into the common 2017 Lincoln MKZ battery problems, offering solutions for diagnosis, repair, and prevention. We’ll cover everything from simple troubleshooting steps to more complex issues requiring professional assistance.
Common 2017 Lincoln MKZ Battery Issues
Several factors can contribute to battery problems in a 2017 Lincoln MKZ. These range from simple issues like loose connections to more complex problems with the charging system. Understanding these issues is the first step towards finding a solution.
Battery Draining Quickly
One of the most common 2017 Lincoln MKZ battery problems is rapid battery drain. This can be caused by several factors, including parasitic draw from interior lights, faulty electronics, or a failing alternator.
- Parasitic Draw: This occurs when electrical components continue to draw power even when the car is off. A common culprit is a glove box light or trunk light that stays on due to a faulty switch.
- Faulty Electronics: Malfunctioning electronic systems, such as the radio or navigation system, can also drain the battery.
- Failing Alternator: The alternator is responsible for recharging the battery while the engine is running. A failing alternator won’t properly charge the battery, leading to a gradual drain and eventual failure.
Battery Won’t Hold a Charge
If your 2017 Lincoln MKZ battery won’t hold a charge, even after a jump start, the battery itself is likely the problem. Over time, batteries lose their ability to hold a charge, especially in extreme temperatures.
- Age of the Battery: Car batteries typically last 3-5 years. If your battery is older than that, it’s likely nearing the end of its lifespan.
- Extreme Temperatures: Both extreme heat and extreme cold can shorten the lifespan of a battery.
- Corrosion: Corrosion on the battery terminals can prevent the battery from properly charging and discharging.

Diagnosing 2017 Lincoln MKZ Battery Problems
Proper diagnosis is crucial for addressing any 2017 Lincoln MKZ battery problems effectively. Here’s how you can identify the root cause:
Testing the Battery
A simple multimeter can be used to test the battery voltage. A healthy battery should read around 12.6 volts when the engine is off.
- Voltage Test: Connect the red lead of the multimeter to the positive terminal and the black lead to the negative terminal.
- Load Test: A load test can be performed to determine the battery’s ability to hold a charge under load. This test is typically performed at an auto parts store.
Checking the Alternator
The alternator can be tested using a multimeter while the engine is running. A healthy alternator should output between 13.5 and 14.5 volts.
Inspecting Wiring and Connections
Loose or corroded battery cables can prevent the battery from charging properly. Inspect the cables for any signs of damage or corrosion.
How to Fix 2017 Lincoln MKZ Battery Problems
Once you’ve diagnosed the issue, you can take steps to fix the problem. Some issues can be easily resolved at home, while others may require professional assistance.
Cleaning Battery Terminals
Corrosion can be cleaned using a mixture of baking soda and water. Disconnect the battery cables before cleaning the terminals.
Jump Starting the Car
If the battery is completely dead, you can jump-start the car using jumper cables and another vehicle or a portable jump starter.
Replacing the Battery
If the battery is old or won’t hold a charge, it will need to be replaced. It’s essential to choose the correct battery type for your 2017 Lincoln MKZ.
Seeking Professional Help
For complex issues involving the alternator or electrical system, it’s best to seek professional help from a qualified mechanic. Remote diagnostics and software programming may be required in some cases.
Conclusion
Addressing 2017 Lincoln MKZ battery problems promptly is crucial for preventing further damage and ensuring the vehicle’s reliability. By understanding the common causes and solutions, you can keep your Lincoln MKZ running smoothly. Regular battery maintenance and timely replacement are key to avoiding future issues.
