Compustar remote starter weirdness

[McSam]

I had a Compustar CS4900 system installed 2 days ago in my 2015 3.8, and I've noticed intermittent strange behavior. Since the problems are intermittent, before I return to the dealer I would appreciate forum feedback if any aspect of the following sounds familiar so I know it's not just in my head or my own goblins. Note that sometimes the issues depended on whether I used the Compustar remote or the Lock-Lock-Lock code on the OEM remote. Unfortunately I couldn't keep up with all the variability so for the purposes of this list I've mostly lumped them all together:

1- Yesterday I noticed that the driver's airbag warning light was constantly red all day. By this evening this was no longer the case; it remained Off after the car started. Nor did I remember seeing the problem on the first day of installation.

2- Several times the remotely started car would turn itself off right after I stepped on the brake (while in Park). Most of the time stepping on the brake in Park resulted in what I think is the normal "taking over" behavior. In my case this meant just turning on the Navigation-AV display. I THINK this issue depended on whether I unlocked the car door by pressing the door handle or via the OEM fob. I'm not sure if it also happened if I used the Compustar fob to open the door.

3- Usually (and annoyingly) I would have to squeeze into the seat which had moved all the way forward to the steering column, but a couple of times it seemed like the seat had remained pulled back.

I know I'm forgetting some other weirdness, but these are the most important. Thank you in advance for any comments.

#1 Should not be related. Coincidence? No idea unless installer bumped a connection.
#2 Yes, don't know if unlocking with fob makes any differencr but I;ll try it to see what happens
#3 My seat does move to the #1 memory position. I can get in that way or I have the #2 memory set for the all back position.

The second memory button idea is useful (at the expense of a quick position for when my wife drives).

Can you please explain the "Yes" at the beginning of your #2 comment?

Thank you.

Yes, shuts off. Not sure of the scenario if the fob unlocks if it makes a difference.

Anyone else have this brake shutdown issue? Definitely a flaw and not a feature!

I just encountered another weirdness that I didn't remember yesterday:

4- Cannot use any fob to pop the trunk once the car has started. Only option is to grab the trunk latch. No fun while carrying heavy shopping bags. This is unlike the former Bluelink remote system which allowed me to carry the fob and press the button as I approached the started car.

BTW I called the dealer about #2 and he was familiar with the issue, saying that the shutdown happens when stepping hard on the brake instead of tapping it. Totally untrue. It happens randomly regardless of brake pressure. And when it does, the side mirrors fold in, as if I had exited and locked!! Another fun fact: the shutdown is followed by a 3-second high whistle coming from the engine compartment.
