I have a 2019 C7 Stingray. When I got to work, I checked my email and got 2 notifications from On Star. I posted 1 of the warnings below. The second warning was sent at the same time saying that a problem with the anti-lock brake system was detected.
Car drove completely fine. The dashboard itself had no warning lights or notifications. If I did not have On Star, I would not have even known about these warnings.
Have any of you received these warning notifications, and have they panned out to be anything?
I'm going to the dealer next week to get it checked out, as I am still under warranty.

I have the LED side markers on my car and yes, I get the TPS warning on the dash, but have never seen anything about the Stabilitrak system having issues.
The Stabilitrak system operates differently when there is a TPMS error. I felt the difference once and thus looked it up. This may be sufficient to send an error to the Mother Ship.
Per the manual:
If the Tire Pressure Monitor System
(TPMS) system is malfunctioning
and the DIC displays SERVICE
TIRE MONITOR SYSTEM,
StabiliTrak will be affected as
follows:
. StabiliTrak cannot be turned off
by the driver.
. If StabiliTrak is off, it will be
turned on automatically.
. Competitive Driving Mode or
Performance Traction
Management is unavailable.
. StabiliTrak will feel different in
aiding and maintaining
directional control.
I got that message from OnStar. Right after I had my car dynoed. I imagine something about the front wheels being stationary and the rears going 100+ mph on the rollers was enough to freak the system out.

I received the same Onstar warning when the front right pressure went blank from the LEDs when on.
Give OnStar a call and ask them if they can provide the DTC that set. OnStar doesn't just send out erroneous messages. The car must have detected an issue and set a code long enough for the VCIM to send a message to OnStar. Stability Control issues will not set a CEL or set a code that can be read by a basic OBDII code reader. You need a scanner that can read ABS codes and is also able to read the history file.
The other thing you should do is change your OnStar account to show your Servicing Dealer. That way a message goes to them Vs McMulkin unless you happen to be in NH Vs California.

Yes I received the exact same two emails. Mine was in shop having exhaust and intake work at the time so I just assumed it had something to do with that. Car was dyno-tuned also.
Occasionally I’ll get a random message pop up but nothing is actually wrong. I chalk it up to the wonderful world of computer code getting confused.
My 2015 Stingray threw some odd warnings from OnStar occasionally, including warnings about my hybrid technology and 4WD systems. Heaven forbid those should malfunction. OTOH my 2017 GS has shown no warnings at all in 3½ years.
