Jeep Grand Cherokee Beeping? (12 Common Causes)

The Grand Cherokee was introduced in ’93 and is currently Jeeps most popular model.

Like any other vehicle, the Grand Cherokee uses various beeps, chimes and noises to alert the driver.

If you’re unsure why your Jeep keeps beeping, this article is here to help.

Jeep Grand Cherokee Beeping

A common cause of beeping on a Jeep Grand Cherokee is related to Navigation Alerts for speed cameras and red light cameras etc, by disabling the warnings via the Uconnect display the beeping should stop.

Navigation Alerts

If you hear a beeping noise whilst you’re out driving it may be caused by certain navigation alerts and warnings for speed cameras / red light cameras and school zones etc.

These can be disabled via the Uconnect display screen under the Navigation mode – you will need to disable the warnings.

You need to press Nav and then Settings to disable the safety camera feature.

Navigation –> Settings –> Speed Limit –> SHOW SAFETY CAMERAS (Uncheck this box)
Navigation –> Settings –> Speed Limit –> ANNOUNCE SAFETY CAMERA WARNING (Uncheck this box)

For most drivers, unticking the Safety Camera Announcements should solve your problem.

Here’s what some owners had to say:

“I just got my Jeep yesterday and noticed the same thing, dealer and service people were no help, I finally (after much frustration) found turning off the speed and camera alerts resulted in no more beeping.”

“Turned off the camera warning and the beeping stopped!” 

“Go to where the speed camera warning is and untick, works for me turning off – drove me nuts and with trial and error no more beeps”

Dirty Sensors

The Grand Cherokee has various sensors located on the vehicle.

If these become dirty, covered with ice or blocked it can trigger unwanted beeping.

Check all the sensors – front, back and the lane detection sensor – and make sure they are clean and free of debris.

Uconnect Software

Make sure that you are running the latest software for Uconnect, otherwise you may hear some unwanted beeps.

Go to the driveuconnect website and type in your VIN number.

It will tell you whether there is an update for your vehicle.

Alternatively, you can try rebooting the Uconnect system.

Parking Brake

If the parking brake is not released when you begin to drive, a chime will sound warning you that the parking brake is still on.

Sat Nav

Some owners have found that it was in fact their Garmin Sat Nav unit causing the beeping.

Once unplugged they had sweet silence.

Weight on the Passenger Seat

If you’ve got an item such as some groceries, a bag or your pet dog on the passenger seat this can trigger a beeping noise as your Jeep will think your ‘passenger’ needs to buckle up as it detects a presence on the seat.

You can simply buckle the seatbelt to see if this stops the beeping.

Faulty latches or Sticking Door Mechanisms

If you’ve got a door latch that’s sticking this will make the Jeep think you’ve got a door open or ajar when you haven’t.

This is a common cause of beeping on many car models.

Try giving a good clean to all door mechanisms and lubricating with WD-40, make sure they all open and close properly.

12V Battery

If the battery is starting to die you may hear a warning beep, most 12V car batteries last 3-4 years on average.

You can always check the battery life with a voltmeter, by measuring the voltage across the battery’s terminals or have it checked by a trained professional.

If it’s under 11V then this is causing the beeps and you’ll need to replace it.

Oil & Fluid

It’s a good idea to check fluid levels are all correct, such as:

  • Engine oil
  • Coolant
  • Power steering fluid
  • Brake fluid
  • Windshield washer

XM Radio

If you have XM radio active, there may be a beep if you have a favorite team selected on one of the sports stations.

Here’s what one owner had to say:

“When I first got mine, somehow I selected to get a notice if my team scored, the game started, etc…Drove me crazy for a while until I figured it out.”

Forward Collision Warning (FCW)

Some Grand Cherokee owners have reported issues with their Forward Collision Warning.

If you suspect this might be the case your best option is to speak with your dealer.

Water Pump

If the beeping noise is coming from the engine bay and sounds like a sonar beep – very computer-like, not mechanical a sound – then you may need to get the water pump replaced.

This is quite a common issue and you’ll find several reports of this across Jeep owner forums.

Jeep Grand Cherokee Beeps 3 Times

If you hear 3 beeps from your Grand Cherokee check your overhead display, although a common cause of 3 beeps is low washer fluid. You should also check and/or reset ur overhead console for service checkup.

Some of the main causes of 3 includes:

  • Leaving a turn signal on
  • Low fuel
  • Low washer fluid
  • Service due
  • TPMS (low tire pressure)
  • Hatch not shut properly

Jeep Grand Cherokee 6 Beeps

If you hear 6 Beep from your Grand Cherokee check your overhead display (Electronic Vehicle Information Center). A common cause is low coolant.

Some of the main causes of 6 includes:

  • Low coolant
  • Leaving a turn signal on
  • Low fuel
  • Low washer fluid
  • Service due
  • TPMS (low tire pressure)
  • Hatch not shut properly

Jeep Grand Cherokee Liftgate Beeping

A common cause for the Jeep Grand Cherokee liftgate beeping is the alert chime going bad.

The part itself is easy enough to find online but the tricky bit is actually fitting the thing.

You will have to remove the rear trim panel to access it and while replacing it is easy getting at it and putting everything back without mucking up the trim is not so easy.

It’s probably best to see if you can get it fixed under warranty first.

Failing that, find a mechanic with the right tools for the trim panel to avoid any unnecessary damage.

If it’s not the alert chime, we suggest booking an appointment with your dealer.

Jeep Grand Cherokee Horn Won’t Stop Beeping

A common cause of a Grand Cherokee horn that won’t stop beeping is a faulty clockspring.

This was also a common problem on the Jeep Wrangler, if your not mechnaically inclined ask your dealership to take a look.

Other horn honking causes include:

Heat Expansion

It may also be solar heating expanding the airbag and tripping the horn.

GM had a similar problem years ago when their higher priced cars had a squeeze ring horn around the inside edge of the wheel rim. It would get so hot inside the car that the plastic would swell up and close the circuit.

12V Battery

It could also be caused by a dieing 12V battery.

Have your battery checked out first (easiest to diagnose and rectify) and ensure the connections are tight and free from build-up.

A battery that’s about to die can cause various problems.

You can also try simply unhooking the battery, leaving it for a minute, and hooking it back up.

Alternative Suggestions For Beeping Problems

Disconnect the Battery

Disconnecting the battery for a certain length of time resets the Powertrain Control Module (your vehicle’s brain) and other electronic systems.

Disconnect the battery for 60 seconds.

Alternatively, you can try disconnecting for 24 hours.

Check the Gauge Cluster and Overhead Display

When the beeping occurs can you see any lights come on at the same time on the gauge cluster or overhead display?

This can give a big clue as to what’s causing the beeping.

On some vehicles, a warning beep indicates a bulb in the gauge cluster is blown.

Take it to a Jeep Dealership

If needed, take your car to the dealership.

Tell them you are NOT paying for a check on what the problem might be.

Ask them if they will check it for free.

Most dealerships and other places do quick/initial diagnosis for no money as they plan to make money for the repair of your vehicle.

Check for Recalls or TSBs:

By entering your vehicle’s VIN number on Jeeps recall page you can determine whether or not there is a recall for your vehicle and if there is you’ll want to get it fixed.

Similarly, a quick google search will help you determine whether there is a Technical Service Bulletin for your Jeep.

These are less serious but may give a reason why your vehicle is beeping.

A recall is issued by a vehicle manufacturer for issues that are safety-related, while a TSB covers components that may be malfunctioning but don’t compromise the safety of the vehicle.

Diagnosing Beeps With a Scanner

Another possible option if you’re hearing a beeping sound is to use an OBD2 diagnostic scanner tool.

These are fairly easy to use, you simply plug them into your car – there’s usually an OBD2 port under the steering wheel.

Once you have the scan codes you can research these online specifically for the Trailblazer.

There are also OBD apps available so you can connect your Jeep straight to your smartphone (either with a cable or Bluetooth) without even needing a scanner.
