The 2017 Jeep Grand Cherokee is a spacious, rugged, and reliable SUV, known for its advanced features and versatility. One feature that owners often cherish is the remote start, which allows you to start your vehicle from a distance, ensuring your car is comfortable and ready when you are. However, you may encounter situations where your remote start feature is not working as it should. This article delves into common reasons for remote start malfunction and effective solutions to get it back up and running.
Understanding Remote Start in the 2017 Jeep Grand Cherokee
Before diving into troubleshooting, it’s essential to understand how the remote start system works in the 2017 Jeep Grand Cherokee. The remote start feature is designed for both convenience and security, enabling you to start the engine via the key fob. This feature also allows for the climate control system to be adjusted so that the interior temperature is comfortable by the time you enter the vehicle.
Common Reasons Your Remote Start Might Not Work
Even with advanced technology, issues may arise that can inhibit the remote start feature. Here are some common reasons why your remote start may not function as expected:
1. Key Fob Issues
The key fob is integral to the remote start process. If your remote start feature isn’t working, the first step is to check your key fob.
- Dead Battery: The battery in your key fob might be dead. If the key fob does not work for any functions, it’s time to replace the battery.
- Damaged Fob: Physical damage to the fob can interfere with its functionality. Look for cracks or other signs of wear.
2. Vehicle Security System
The anti-theft system is designed to prevent unauthorized access to your vehicle. If your vehicle doesn’t recognize the key fob or senses potential tampering, the remote start function may not activate.
3. Transmission Issues
For safety reasons, the remote start feature only activates if your vehicle’s transmission is in ‘Park.’ Ensure that your vehicle is not in gear and check for any related malfunctions.

The remote start system will also disable itself if it detects that a door or the hood is open. It’s important to ensure that all doors are securely closed and that there’s no interference with the door locks.
5. Low Fuel or Engine Issues
Some vehicles will not permit remote starting if the fuel level is too low or if there are existing engine issues. Make sure your fuel tank is sufficiently filled, and conduct a basic inspection of the engine.
6. Software Glitches
Modern vehicles, including the 2017 Jeep Grand Cherokee, rely on computer systems and software to control various functions, including remote start. A temporary software glitch might prevent the feature from working as intended.

What should I do if my remote start isn’t working on my 2017 Jeep Grand Cherokee?
If your remote start system isn’t functioning, the first step is to ensure that your vehicle is locked. The remote start feature only operates when the doors are locked, as a safety measure. Next, check the battery in your key fob; a low battery can prevent the signal from being sent. Make sure to replace the key fob battery if it seems weak.
Additionally, see if any warning lights appear on your dashboard when you attempt to start the vehicle remotely. If the check engine light is illuminated, the remote start feature may be disabled until the issue is resolved. Consult your owner’s manual for guidance on troubleshooting warning lights and potentially resetting the system.
Can I use my remote start if my vehicle’s hood is open?
No, the remote start feature will not operate if the hood is open. This is a built-in safety precaution to prevent accidental starts while someone is working on the engine. Make sure your hood is securely closed before attempting to use the remote start.
If you frequently need to start your engine while working under the hood, consider using the ignition key instead to avoid complications. Always prioritize safety and ensure that all components are securely in place before starting the vehicle.
Why does my 2017 Jeep Grand Cherokee turn off shortly after starting with the remote?
If your Jeep Grand Cherokee shuts off shortly after using the remote start feature, this may indicate that a safety mechanism has been triggered. Common reasons include an open door, an unfastened seatbelt, or an issue with the vehicle’s security system. Verify that all doors are closed and that the key fob is within range.
Additionally, check the vehicle’s fuel levels and engine conditions. If there’s a malfunction, such as a sensor issue or insufficient fuel, the system may shut down to protect the engine. Diagnostics by a professional may be needed to identify and rectify any underlying problems.
What might cause my key fob not to communicate with the remote start system?
If your key fob is not communicating with the remote start system, start by checking the battery in the fob. A weak or dead battery will prevent the fob from sending signals effectively. Replacing the battery is a simple, cost-effective first step you can take to resolve the issue.
If the battery isn’t the problem, there may be interference from other electronic devices or systems. Additionally, physical damage to the key fob can affect its functionality. If you’ve ruled out these issues and the remote still isn’t working, it may be necessary to reprogram the fob or consult a professional locksmith or dealership.
How does extreme weather affect my remote start function?
Extreme weather conditions can significantly impact the performance of your remote start system. Extremely cold temperatures may lead to a weaker battery in both your key fob and vehicle, making it more difficult to establish a connection. Additionally, cold weather can thicken engine oil, resulting in the engine not starting efficiently.
Conversely, high heat can also affect electronic components and batteries. If possible, try to avoid extreme weather conditions when using your remote start. Ensuring that your vehicle is well-maintained and that batteries are in good condition can help mitigate the issues caused by weather extremes.
How can I reset the remote start system in my Jeep Grand Cherokee?
Resetting the remote start system can often resolve minor glitches. To perform a reset, you can start by disconnecting and reconnecting the vehicle battery. This process effectively clears some electronic settings and may resolve issues related to the remote start.
In some cases, you can reset through the vehicle’s settings menu, accessed through the infotainment system. Check your owner’s manual for specific instructions tailored to your model. If the problem persists after attempting a reset, consulting with a dealership or technician familiar with Jeep systems may prove necessary.
Can I use the remote start feature with my smartphone?
Yes, using your smartphone to access the remote start feature is possible if your vehicle is equipped with the Jeep Mobile App or similar technology. Ensure that you have installed the official app and created an account. From there, you can initiate remote start commands from your smartphone, provided your vehicle is compatible with this function.
Always keep in mind that requirements or limitations may apply, such as needing a subscription or an adequate cellular signal. Refer to the app’s guidelines for proper usage and ensure your vehicle is within the operating range for smartphone commands.
Is there a safety feature that disables remote start in my 2017 Jeep Grand Cherokee?
Yes, your 2017 Jeep Grand Cherokee is equipped with several safety features that can disable the remote start function if certain conditions aren’t met. For instance, if any doors are unlocked or ajar, the system won’t initiate. This is to ensure that the vehicle cannot be started without the operator’s knowledge or safety precautions in place.
Furthermore, if any of the safety sensors detect issues, such as a malfunctioning alarm system or low fluid levels, the remote start feature may disable itself to protect the engine and occupants. Familiarizing yourself with these safety features can assist in troubleshooting any problems with the remote start system.
