Help! New 2019 Trailhawk going haywire & unable to start

My 2019 Trailhawk is 1 & 1/2 months old and this happened today. I can't seem to upload the video files on here so hopefully a db link will work.

The voice you hear in the vid is coming from the Blackvue dash cam which is connected to the obd. Set to shut off after 6hrs of being on. The dash cam was on my previous 2016 GC without any problems or issues.


The last time the car was driven was about 6 days ago. I went to go see a client this afternoon and could not start the vehicle. All features of the vehicle was either unavailable or had a service warning. With the exception of the first time today that I unlocked the vehicle, the rest of the time I could not lock/unlock from the door panel nor the outside handle. Trunk could not open. Constant chiming whenever the door was opened. I was running late for client so I took another vehicle. Was able to lock doors with key fob.



Came back an hour later, the car was completely dead. Could not unlock with fob either. Had to use manual key to unlock and get my jumpstart battery kit. Jumpstart kit could not start vehicle. What I did notice even when the vehicle was dead is that the glow lights around the 2 usb slots in the console was lit.



Anybody have any suggestions? Service depts of local dealers are closed atm. My next step was to call AAA tomorrow.

Question. Did the issue(s) occur before the dashcam install? Not an expert but it sounds like the proximity sensor for the fob is malfunctioning / not detecting the fob and or that your dashcam is draining the battery completely. Try disconnecting the dashcam, fully charge up the battery, clear any errors and run like that for a week or so.

Sounds like a dead battery. The electronics on these vehicles are sensitive to battery voltage, and weird things can happen if the battery voltage is low. Seems like a battery charge or jump start are in order, then figure out if your battery is bad or something is draining it.

I’m hoping you guys are both right and that it’s a battery issue cause those warnings didn’t look good. I couldn’t jumpstart it with my Micro-Start XP-1. I eventually disconnected the dashcam. Going to charge up the XP-1 to full and try in the morning again.

Good deal. It also wouldn't hurt to run a battery tester on it as well. I believe Autozone, O'Reilly's and other major auto parts stores may be able to run a test on them for free.

Sounds like a voltage issue, probably a run down or faulty battery, but the alternator may not be charging efficiently. There have been a few parasitic loss reports over the years caused by one module or another. These can be difficult to track down.

All the control modules have voltage sensors and will panic when the bus voltage gets too low for them, and you can get a bunch of seemingly unrelated error messages and unpredictable states.

The AGM batteries used in the WK2 often test good, but will fail in use, don't bother with it.

If you have the V6, the smaller ESS battery can cause these kinds of symptoms too.

If you have an battery charger thats suitable for AGM batteries, give that a shot. AAA may be worth a shot. Once you get it running let it charge for awhile.

The dealer probably won't know if its an electrical load you put on and caused the battery to drain, or there is a fault somewhere. So its probably best to get it running and monitor the voltage over time and after setting overnight. But talk to the dealer, see what they want to do under warranty. They may just have it towed in.

Yes it’s the V6. Tried to jump it again with the XP-1 full charged. No go. Out of the 5 power indicator lights on the XP-1, the attempt used up 2 of the lights. Waiting on AAA now.

This def sounds like a battery issue. Leave that dashcam unplugged. You can test the battery voltage with a voltmeter on the lugs under the hood or underneath the passenger seat directly. The voltage should be above 12V if it's not then the battery is no go. If it's below 12V then it's def a problem.

Had a very similar problem with my 2015 altitude. It was the in the body shop for hail damage repair. Well they called to say it was ready for pick up. Looked car over to check was done and waved good bye, however car would not start and was saying on main dash, make sure clutch is depressed and in neutral, Clutch!!! It’s an automatic! Long story short, tried jumping from external battery starter.. no go, called mechanic in, disconnect earth terminal to battery to reset it, hooked up to jump start battery, cleared codes..... reason they left the rear internal passenger light on....(I found it on) drained battery.. Hense all the weird dash messages. Basically the battery voltage was so low the ecu was confused... yup these cars are sensitive. Hope that helps. ..

Thanks for everyone's recommendations & advice. Thank you JeepCares for your post too. It finally came back after a jump from AAA. The guy told me I had to drive around over 15 mph for an hr to fully charge the battery (which I did). He also tested the battery, alternator, & starter and said they were all fine. It was a learning experience...didn't know all those warning signs could show up from low battery.

So the dashcam is set to operate in park mode & shut off after 6hrs which is the lowest time set. The firmware defaults at a pretty high sensitivity setting, so when I checked out all the recorded footage (1min length each time it's triggered), it was picking up everything in the apartment garage....ppl walking by, cars driving in & out, etc. I'm guessing that's the culprit.

There may have been a low voltage warning, but it had long expired in the week it was sitting. Most everything is computer controlled and if the battery was drained enough to not provide the computers or cluster with enough power, status state is unpredictable, so one has to pull out the old school voltmeter. My 60s era car's low voltage warning was that it wouldn't turn over.


If you can get the OBD error codes read, there may have low voltage conditions in the error logs.

Would an OBD reader and app like Torque Pro help diagnose voltage levels or probs or does it not work well with the WK2?

I had great results with my old Xterra, but never used it on my newer jeeps.
