Luckily, in this article, we’ll give you the top 3 reasons a Jeep Grand Cherokee won’t start and some tips on what to do about it! We’ll also answer some frequently asked questions on the subject. Let’s get started!

Top 3 Reasons Why a Jeep Grand Cherokee Won’t Start

It can be incredibly frustrating to be stranded with a Jeep Grand Cherokee that will not start. Even if you have some prior knowledge of the vehicle and the way it works, figuring out what the problem is can add to this frustration by being overwhelming. 

To help with this, we’ve narrowed it down to the top three, most common reasons a Jeep Grand Cherokee fails to start. Take a look at the list below to see if the problem looks familiar:

  1. Dead Battery
  2. Failed Starter
  3. Malfunctioning Alternator

Let’s examine each of these reasons to see how you can tell that it is the culprit when your Jeep Grand Cherokee won’t start. 

1.   Dead Battery

According to Repairpal.com, around 38% of the times that a Jeep Grand Cherokee won’t start, the issue is your battery. If the car is making a clicking noise and the lighting inside the car is dim or nonexistent, the battery must be replaced or recharged. 

You can jump the battery of a Jeep Grand Cherokee if another vehicle with a working battery and jumper cables are present. When this is the case, park each car, hood-to-hood, without them touching. 

Then, clip the red end of the alligator clip to the positive terminal on the deceased battery. Connect the other end of the red cable to the positive terminal of the working battery. Next, connect one end of the black jumper cable to the negative terminal on the working battery, followed by the other end on an unpainted part of the metal on the Jeep Grand Cherokee. 

Afterward, the engine of the car that is working should start and be run for at least two minutes. Start the dead Jeep, too, allowing the battery to recharge. When you remove the cables, do so in the opposite order of when you attached them! Make sure to drive the Jeep for at least 30 minutes afterward to promote it’s ability to recover. 

If a jump doesn’t work, call a professional; you’ll need to replace the battery.  

2.   Failed Starter

If the engine of your Jeep Grand Cherokee won’t turn over at all or make any signs of life when you try to start the car, you may have a failed starter. However, if you’re hearing a clicking, whirring, or grinding sound, these can also be signs of a failed starter. One of the most alarming symptoms is smoke issuing from the hood of the Jeep. 

Jump-starting the car, as mentioned above, can help a Jeep with a bad starter to get started, but it won’t be a long-term solution. Ultimately, your starter will need to be replaced. 

3.   Malfunctioning Alternator

Finally, a malfunctioning alternator is a common reason for the car refusing to start. You know you have a malfunctioning alternator if the devices you plug into your car, like a phone or speaker charger, refuse to charge. 

Other telltale signs could be a screaming noise when the vehicle manages to start, or, most commonly, the battery warning light flashes. Again, you can solve this problem briefly by jumping the battery with another car and jumper cables, but a mechanic will need to fix the alternator’s issue.

Frequently Asked Questions

Even with the above-mentioned list and the possible solutions, an automobile like the Jeep Grand Cherokee is a complex machine, and you may have more questions. Not to worry; we’ll set you up with the answers to the web’s most frequently-asked questions on this topic so you can be well informed. 

Why won’t my Jeep Grand Cherokee Start but has power?

If a Jeep Grand Cherokee has power, but refuses to start, you’ll need to look at the battery itself. If there is a connection issue, then the battery may be providing power to things like the radio or lights, but not enough to get the car moving. 
Also make sure to examine the starter, the ignition switch, or the spark plug. If any of these are corroded by rust or debris, or worse, broken and damaged entirely, it can keep the vehicle from starting. 

What do you do when your Jeep Grand Cherokee won’t start?

Sometimes, a car refusing to start can feel like such a worst-case-scenario that you feel too overwhelmed to know what to do! The first step is to calmly examine the machine. Are there any errors or alert lights on? 
Next, open the hood of your Jeep Grand Cherokee and try jump-starting the Jeep with another car and the use of Jumper Cables. If you have access to a car battery charger, try hooking it up and recharging the battery. If neither of these plans yields results, you may need a battery replacement.
Call the nearest vehicle service provider that works with your budget and remain in the car safely until help arrives.  

Why is my Jeep not starting and clicking?

Perhaps your Jeep Grand Cherokee refuses to start, and in addition to this frustrating problem, is making a clicking noise. If this is the case, it is because your battery is weak. The clicking noise that you are hearing is the result of your battery trying to forward what little power it has to the starter. 
That, in turn, causes the flywheel to engage and make a clicking sound. However, it will not be enough to start the Jeep and you’ll need to recharge the battery or replace it. 

In Conclusion

To sum it all up, there are three main causes when you find yourself asking “Why won’t my Jeep Grand Cherokee start?” These are usually a dead battery, a malfunctioning alternator, or a failing starter.

Each of these problems can be temporarily resolved by jump-starting the Jeep. However, a mechanic will need to permanently fix parts of the Jeep that don’t work.
