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.
2020 Rocky Ridge K2 Silverado 5.3L 14K miles First time posting. Have been expereincing intermittent brake lights staying on after engine shut down for several weeks. Took it to the dealership, who ran a diagnostic on the truck and came back with "all things look normal, no codes". By the time I got home, the brake lights were in a state of constant "on" and I was able to restart the truck without applying the brake, even with the key fob outside the vehicle. Received several Onstar warnings to "Service Parking Brake". The parking brake had engaged and would not release. I disconnected the battery for 20 minutes, reconnected the battery which cleared the code. Called the dealership and was told I would have to leave it with them for awhile (several days to a week) to find out what the issue is. Would be ok except they do not provide a loaner car and rentals are thru the roof in our area ($100/day) so I have been living with this inconvenience until I can find an alternative way to work (80 miles rt). Then this happened over the past weekend: While driving back from the lake with my boat in tow, the truck went into a critical brake failure mode. Here is the series of events. Moored boat at dock and went to retrieve truck to remove boat from water. Could not unlock door on truck with FOB. Truck was "dead". No voltage activity. Used 12v portable jump pack to start vehicle. Let run for @20 min before proceeding to drive home with boat attached. Check engine light was on for 30 seconds then went out, but no warning dialog boxes. After we were on the road for @15 min, in rapid succession, I received the following warning dialog boxes: Service Trailer Brake System Service ESC Service Parking Brake Brake System Failure - 62 MPH Top Speed Check engine warning light Traction Control Off warning light ABS Off warning light As soon as I saw this, I tried to apply the brakes and they went to the floor. As you might imagine, it was chaotic in the vehicle when it became apparent that the vehicle along with the 6000lbs of Boat/trailer in tow was not going to stop in any timely fashion. Along with the trailer brake failure and vehicle brake reduction, the backup surge brakes on the trailer would not engage due to the lack of quick inertia braking force. I had the pedal to the ground and eventually we came to a stop. The rest of the ride home (2 miles) was a 5mph white knuckle event. The insult to the injury is there has been no warnings, email, text or posted on account from Onstar about this series of events but... I did get one on the same day that my Oil change is due. I am posting the screen shots I took after we came to a stop. It is being towed to the dealership tomorrow. I will let you know what happens. I absolutely love my truck. It is the 5th Chevy that Ive owned, and sadly the worst one of the bunch. M
While out on a dirt road enjoying my newly installed prerunner suspension I successfully turned off the Traction Control and ESC (electronic stability control). Went for a run down the woops and ESC turned itself back on and applied the brakes during one of my drifts. COMPLETELY unexpected and caused the truck to handle undesirably (to say the least). In talking to another Chevy guy he said the ESC turns itself back on at 35mph and above!... Is there anyway to 'tune' this out and make it stay off when desired? This is exactly why I held onto my 05 Duramax for so long. It had ZERO 'nanny hardware' that would f*#k with me while offroading.
My 2019 SIlverado 4x4 has 3,100 miles. It was parked in the driveway last week and when I attempted to enter it into the garage, and in Drive, it sat there for a second or two, and then lurched into the garage. I instanteously hit the brakes and got it stopped. When I pressed the gas, the truck just stood still, then took off into the garage. Now, today, as I backed out of the driveway for a quick errand, the emergency brake would not release, then it released, but as I selected Drive, it refused to move. I played around with it several times, pressing the brake pedal as instructed, and finally got it to go. However, I had now brake assist. It required a ton of pressure to get it to stop. The dash light up like the 4th of July. BRAKE showed up in red, engine in yellow, Traction Control in yellow, Tire Pressure (quickly vanished), ABS, and Service ESC. Am heading to the dealer (48 miles) in the morning. I was going to connect my DTC and see what was showing, but will refrain, so dealer can see for themselves. I've noticed a couple of intermittent quirks since I've owned it (July 2019), but things seemed to resolve themselves. I did receive December recall and they will get that looked at in the morning. Am attaching a photo of the dash as i sits now. The -14.6V DC light is from a piece of equipment I have installed. Anyone else out there having issues? Also, photo shows less the 30psi oil pressure at idle, a bit low I am thinking
