The Jeep Wrangler has earned a reputation for being a rugged and reliable vehicle, suitable for off-road adventures as well as daily commutes. One of the modern conveniences that Jeep owners appreciate is the auto start feature, allowing them to start their vehicles from afar. However, when this feature suddenly stops working, it can be both frustrating and inconvenient. This article will explore the common causes of auto start malfunction in Jeep vehicles, potential solutions, and prevention tips to keep your auto start feature running smoothly.
Understanding the Jeep Auto Start Feature
The auto start feature, often referred to as remote start, allows drivers to start their Jeep without having to be inside the vehicle. This functionality can be particularly beneficial for warming up the engine in winter or cooling down the interior during scorching summer days. It’s an innovative convenience that adds an extra layer of comfort for Jeep owners. However, there are several reasons why it might stop functioning.
Common Causes of Jeep Auto Start Malfunction
Understanding the reasons behind the malfunction can help you diagnose the problem effectively. Here are the most common causes of Jeep auto start not working:
1. Key Fob Issues
The key fob is essential for the remote start function. If it’s damaged, the battery is dead, or it has lost its programming, the auto start feature may not work as intended.
Signs of Key Fob Issues
- The key fob doesn’t respond when buttons are pressed.
- The range of the key fob seems incredibly limited.
2. Low Battery Voltage
A low or failing battery in your Jeep can prevent the auto start feature from functioning. Electrical systems, including remote start, rely heavily on battery power to operate properly.
Symptoms of Low Battery Voltage
- The lights on the dashboard flicker.
- Other electrical components (like windows or locks) are slow to respond.
3. Faulty Starter System
The starter system in your Jeep is responsible for initiating the engine when you turn the key or press the auto start button. If there’s an issue with the starter motor, solenoid, or associated wiring, the auto start feature will fail to work.
4. Security System Malfunction
Many Jeep models come equipped with advanced security systems which may interfere with the remote start feature. If the security system is activated erroneously or experiences a malfunction, it could prevent the auto start from engaging.
5. Firmware Issues
Modern vehicles are often equipped with complex software that manages various features, including remote start. Occasionally, bugs or glitches may occur in the firmware, leading to malfunctions in the auto start feature.
Troubleshooting Jeep Auto Start Not Working
Before taking your Jeep to a mechanic or dealership, it’s essential to consider troubleshooting some common issues at home. Below are steps you can take to identify and resolve the problem.
Step 1: Inspect the Key Fob
Start by checking the key fob. Try the following:
- Replace the battery in the key fob to ensure it’s not dead.

If the reading is low, consider jump-starting your Jeep or replacing the battery.
Step 3: Examine the Starter System
To examine the starter system, listen for a clicking sound when trying to start the Jeep. If you hear a click but the engine doesn’t turn over, the starter may require servicing or replacement.
Step 4: Test the Security System
Check if the security lights are flashing when trying to use the remote start. If it appears to be activated erroneously, you may need to reset the security system according to the owner’s manual.
Step 5: Update Firmware
If you’ve ruled out other issues, investigate whether the vehicle’s software requires an update. This can often be done at a dealership or specialized service center. Appropriate software updates can correct issues that interfere with vehicle features.
When to Seek Professional Help
If you’ve tried the aforementioned troubleshooting steps and your auto start feature is still not functioning, it may be time to consult a professional. A certified Jeep technician will have the proper equipment and expertise to diagnose and repair more complex issues such as:

When the driver lifts their foot off the brake pedal, the engine restarts, allowing for a smoother and more efficient driving experience. This technology aims to reduce emissions, conserve fuel, and lower overall running costs.
Many Jeep models come equipped with this feature as part of their drive assistance systems. While it may take some time for new drivers to get used to it, the Auto Start Stop feature can be beneficial for both the environment and your wallet in the long run. However, if this feature stops working, it can be a source of frustration, prompting drivers to seek troubleshooting advice.

While it does not endanger safety, you might consider having it repaired to restore a more efficient driving experience, which can be beneficial for your wallet and the environment in the long term.
Can I disable the Auto Start Stop feature permanently?
Yes, many Jeep owners prefer to disable the Auto Start Stop feature if they find it more distracting than beneficial. Most Jeep models include options in their settings menu to turn off this feature.
