Service Power Steering and Service ESC

[RocksRock]

How does a car qualify for lemon law?

Under the law of most states, for a vehicle to be considered a lemon, the car must 1) have a "substantial defect," covered by warranty, that occurs within a certain time after purchase, and 2) continue to have the defect after a "reasonable number" of repair attempts.

I called Onstar. They show all systems failing. 

Module	Diagnostic Code	Diagnostic Information	Recommended Action
ECM - Engine System	None	Failed to Probe Module	None
SDM - Airbag System	None	Failed to Probe Module	None
VIU - OnStar System	None	No Error Code Found	None
TCM - Transmission System	None	Failed to Probe Module	None
BOI - Bulb Outage Indicators	None	Failed to Probe Module	None
ABS - Braking and Stability System	None	Failed to Probe Module

Mine started w a remote start.

Yay! 217 miles on my 2020 Trail Boss LT and it's showing the following errors:

 

Service ESC

Service Trailer Brake System

Steer assist is reduced, drive with care.

Parking assist not working.

 

I was messing around with the app last night, remote started it via the app and now all this bullshit pops up.

 

Lame.

Mine does it regardless of type of start. The common factor for me is it’s always after parking somewhere for a short amount of time. Like go to the store for 15 minutes and when I start the truck to go home I get all the codes.

Is your power steering working at all?

Power steering works fine, braking is fine. Parking sensors are off and will not toggle on.

All of these issues are unique and different but all of our issues seem to be a bunch of random electrical nonsense BS going wrong all at once.  All of you, call GM and complain!

It’s related to the remote start. 
did it again. I have to turn off. Open door, close door restart. Engine light stays on, but errors go off. 
I have unplugged my iPhone. 
when errors are on display brake pedal not Working. So it affects the brakes. I will check power steering. Went to Oreilys. Threw five codes.

Makes me wonder if this has something to do w on star. I’ve used that remote since I bought it in Sept. just started today?

something has changed.
Maybe on star getting hacked?

What day did you all experience your issues?  Recently?

[RocksRock]

Today. First time.

Lots of recent cases this week.  That's unusual and suspicious.

Mine has done it since I bought it in early December. ~1700 miles on it now and it has done it randomly since it had 50 miles on it. Exact same symptoms as others, though I've never lost brakes. The brake loss is covered in another thread and does seem to be specific to remote start via the app. I don't think the issues in this thread are related to any sort of OnStar hack or problem.
