Trunk ajar light comes on while driving. and panic alarm goes off by its self

you have 2 choices
get car serviced,
or
read below. (pick one?)
sure, this is easy, (system logic not)
but you forgot to say , car starts with key, and runs perfect.
right. for get remove start toy.
certified , = warranted, or some bs.?

runs perfect means zero if the CEL glows running,
does car run perfectly you in seat starting with key and driving?
my guess you mean car stalls, 10second (ONLY ) remote started.
sure.
"engine light" means not running right, on all cars 1988 to now.

the XBM remote start will never work , with any errors from
ECU
PCM
BCM
or TCM
ever.
or if it sees doors ajar or alarms of any kind
by logic and federal laws.
scan it 1st and correct all DTC errors first.
that is what to do. if you are savvy and have a scan tool.
$10 to $100 tool, sold in all autostores usa.

think for 1 second how dangerous this FEATURE, can be.
hummmmmmm (a driverless moving car...)

why not read the FSM book on the 2013?
it covers most the logic, there.

quoted, so you can learn "complexity extreme"

good luck running the engine in your garaged
and everyone eating carbon monoxide in the home.
good luck with that....."the silent killler"

I too had the message center beep randomly but I could never find the culprit due to the brief timing. The alarm sounding off is a different and more annoying problem. All of my research points to the battery being at the end of its life. A weak battery or corroded connection on the ground cable will cause both of your problems. Clean the ground cable where it is screwed to the body too. Do your gauges top out (go to max) at startup? If so your battery is suspect and that can be load tested at most auto stores for free. Never buy a battery with less than 750 CCA.

It sounds to me all you need is to adjust the trunk hatch. Its going out when you hit the brakes so the switch isn't bad. It may be worn but if you can push on it and the light goes out it is the reason your alarm is going off. Make sure there isn't debris under the rubber seal preventing it from fully closing.

alarm its self goosed may have to take it to an auto electrition to disconect the old alarm

Alarm system is detecting a fault. It could be a door latch sensor gone wrong, and it should show a door ajar light while driving, or the hood or trunk sensor disconnected. Most alarms are designed to "arm", even if it detects an open door.

you may have a broke wire in the door harness

I read a service bulletin about door ajar light and power locks cycling while driving which i assume might actuate dome light as well.... rec. fix per service bulletin adjust "swing gate " striker

Good Luck

The door latch has a switch built into it to replace the old door jamb switch. If the switch is faulty the system will think the door is ajar. A scanner will show an open switch.

YOU SHOULD BE UNDER WARRANTY.

there is a switch in each door that senses the door is open, it is called the door ajar/courtesy light switch (imagine that), they stick and have this problem, replace it.
