Looks like that factory anti-theft system needs an update or some kind of fix, definitely not to be disabled.


Life with no alarm is so peaceful and happy. Battery doesn't die from sitting for a week, horn only ever goes off when I press the horn button on the steering wheel, metal key lets me in with no drama, wife can change her mind and hop out of the car at a gas station without setting off 60 seconds of honking. I'm never turning that cursed "feature" back on, nor will I re-enable the panic button that always gets pressed by accident in pockets and purses.

Its not like someone forcing their way into the car is going to be able to steal it. No fob = no go, there is no reaching up and grabbing a fistful of wires and hotwiring them together like in the movies (not on this car). On a smash and grab, if its gonna happen its gonna happen regardless of whether the alarm goes off, they're gonna smash your window and take your stuff, period.

Very easy to add an aftermarket alarm. Something programmable with predictable behavior, something you can bypass easily for camping by pulling a fuse or flipping a hidden switch. Even possible to do a silent alarm that doesn't have a siren but notifies you on your cell phone. If I lived or traveled in rougher areas I'd probably install something aftermarket. Things are pretty calm in my town of 400 people here, and you'd have to be pretty crazy to walk up to my car sitting in the driveway in the middle of the night and start smashing windows while I'm sleeping in the house a few feet away. Our security cameras cover the driveway 24/7. I don't generally leave valuables in the car.

My system (or lack thereof) works fine for me. In my own personal threat and risk assessment the cars rank very, very low on the list of concerns. The house, on the other hand, worries me a lot as its actually unattended way more often than our cars are, and unlike our cars there actually is stuff I care about being stolen in the house, so I've invested pretty heavily on cameras and security for the home.

Well, you are right. I'll need to pay more attention to it, since my car is mostly in a garage that belongs to unattached single house, therefore always fully unlocked as garage is locked. It'd be a completely different story if I need to park it constantly overnight somewhere outside among highly packed building blocks...
It would be interesting seeing a list of all power consuming connections while jeep is locked and idle. That remote always scanning anti-theft system waiting for a pressed key-fob, would be a number one to check. Maybe it is possible somehow to reduce its range and to make some power savings to the battery, hm?

Might be worth mentioning, if it makes anybody feel any better, that my folks have replaced the battery on their 2016 Honda CRV twice since the covid pandemic started and work-from-home became a regular thing for them. Once in May, and once last month. Their CRV has the connected cellular services with remote start from the phone app and GPS "find my car" and all that, and they are having very similar issues.

Most car batteries are designed for short high current events to start the engine and then let the alternator take over...not for being drawn down and siting in a significantly discharged state. Over time this will lead to a reduction in capacity and eventual failure. So unfortunately if a vehicle is repeatedly left for long periods of time without recharging (or like on the dealers lot), even a new battery can be permanently damaged. The battery appears to take a charge but when required to deliver the high starting current, fails the job.

Trickle chargers are one solution however use over longer periods of time they can also cause battery issues. The best way to preserve your batteries is to drive the vehicle on a frequent basis (at least every one to two weeks) and make sure the battery is not discharging to a low level if it is siting. I use an inexpensive LED plug-in cigarette lighter voltmeter on our classic car to check if it needs a charge. Anything below about 12.3 volts gets either a drive or a charge. Of course don't leave it plugged in or it will add to the problem. :)

Same problem. My Jeep Compass is 2018 and I have already changed my batteries 4 times. The dealer replaces the battery every time but I think the problem is somewhere else. That could be an issue for that model.

Hey everyone,

Has anyone else had an issue where their 2018 Jeep compass battery is completely dead after sitting for 2 days or the weekend? I mean dead to the point the doors won't even unlock. I have an appointment to take it to the dealer AGAIN for this reoccurring problem and I was just curious if it was a common problem.

The only thing I have done to the vehicle electric wise was change the dome lights to LED; I'm sure that wouldn't cause an issue.
Yes it happened to my 2019 Jeep Compass

No problems here...I replaced 6 of the interior bulbs with LEDs and added 2 to the "Flags" in the hatch area and also added a LED to the bottom of each door that is connected to the interior lights and the Compass has sat for days with no battery issues.
Hello did you finally get your car fix? And what was the issue because I have exactly the same issue

what was the final verdict? I’ve been dealing with this for about a month?

So we have 3 cars and a bike. I tend to pull the batteries and trickle charge them. When we got the car in May the car (2018 Latitude 2 CRD ) it was only showing about 40% charge. With Covid and working from home the car hasn't accumulated many miles, we also have no idea how long the car was standing before it was purchased. To try and keep the charge up I attached one of those solar charges. Which seemed to keep the charge up in the summer. Checking it today revealed the car telling me 36% and my battery tester telling me low. I was actually going to pull it on Friday but I couldn't find my socket extension bars anywhere. Then on Friday the new tools didn't arrive until it was dark swiftly followed by snow and 50mph gusts. So this morning I decided with freezing temperatures I had to pull it. I've spent some time on the internet looking at how to remove it as I'm used to a retainer and two terminals to undo...So probably the second biggest pain battery removing experience the biggest was a mini digger. The small red retaining by two screws bar went pinging off into the engine bay. I can see it but it's going to be a quest to recover it. Anyway it's off and connected to the new charger I've bought. I'll see what happen when it's charged and refitted.

I have been in the habit as I roll down my drive to shut off the radio and the HVAC.
I'm not convinced these "smart charging" devices were worth the effort. To digress somewhat I read somewhere my Impeza battery doesn't charge unless you have something running like the heater fan. I've been looking at replacement battery options for the car and the options are somewhat limited as I assume the battery is the original 2018 one it's not going to last forever. Although judging by the scratch marks next to the negative terminal it's been disconnected or out at some stage

I just had the same thing happen. The auxiliary battery was dead, causing a drain on the main battery.
