Stabilitrack/ESC/ABS Issues 2019 Trail Boss

Recommended Posts

My wife and I were going to have a picnic by the ocean so went on a sandy (beach sand) road, meant for off road vehicles only. I switched to 4 Hi and while drove in the sand at less than 10mph. After about 5 minutes or so I had warnings of "service ESC" and "steering assist is reduced, drive with care". The truck, which is a 2019 Trail Boss, performed fine and I did not notice any difference in handling. I tried taking off the traction control, putting the truck in park, shutting the truck off for a while, but still the lights stayed on. The lights went off after driving about 5 minutes in 2 Hi. I also recieved emails from OnStar "there is an issue with the ABS system" and "there is an issue with Stabilitrack traction control". I don't think this is normal so it is at the dealer now. They said the initial results are the yaw sensor triggered for some reason...I don't think this is normal, the truck has 800 miles on it, but any ideas what this is or what it means? Thanks.

My 18’ gave the same errors when my vacuum pump failed at 8,500 miles.

The 19's don't have vacuum pumps, steering and brakes are electronically assisted

I received the truck back today and no intervention was needed. They said it was due to offroading and the angles the truck was at maybe. I wasn't driving too hard and ¹¹ said it could come back on but aslong as it goes off there is no issue...so does this mean anytime I go off road the lights will come on, that seems crazy, the truck should be able to handle off road challenges it's a "trail boss"...

My 18’ has electrical steering as well. The vacuum pump controls the brakes. When my pump failed it gave the same 2 codes you got, BUT I also got a service ABS as well. Weird response about off reading tho. I guess I may understand if you were jumping it or doing extreme angles, but I doubt that...

Exactly, I wasn't going crazy the truck is new! Well I'll keep an eye on it. That's sucks your vacuum pump failed - at what mileage did that occur? Thanks for the input.

I experienced the same issue as JayTrailboss with the Service ESC and Steering Assist is Reduced.
