SERVICE BRAKES, STEERING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On a normal trip to work the dash light lit up then gave me these warnings. Service ESC, Service Trailer brake, Brake system Failure-62 mph top speed, steering assist reduced. Dashboard lights that were on, ABS Check Engine, Brake, Traction Control. When I tried to slow down the power assist was gone on the brakes, I had a little braking when I pushed the pedal all the way to the floor as hard as i could, when I went to turn the wheel was hard to turn. I have had no issues like this before. After I managed to stop and turn off then on the vehicle everything came back expect for a warning to service the trailer brakes and the check engine light was still on. It all cleared after a few more restarts. I got the truck to the dealer 4 days later and they said it was the battery going bad even though I was not having any problem starting the vehicle, I had them replace the battery. I am unsure if the problem is resolved, time will tell. What I am sure of is if my daughter had been driving the truck, she would not have had the strength to get the brakes to work or turn the wheel, she would have had a accident for sure.

ENGINE
I was driving to work on Saturday morning [XXX]. As I pulled out of the stop sign and approached 45 mph the engine stop. Making me a hazard within the road. I had to abruptly pull off into a road/yard in order to be safe. All while not having a power as the engine completely stopped. Upon investigation the dealership, Budd Baer in Washington Pennsylvania confirmed the engine had seized up due an issue in rotating assembly.

On Jan 7, 2024, we went to Walmart to shop (DeRidder, LA). The truck was running normal. All gauges were normal and the reason I can say this is because our truck broke down in 2023, so we have a habit of checking them when we start the truck before driving and during driving periodically. When leaving Walmart we were at the red light and the truck just stopped. A message came on and said to shift into Neutral, which we did. The truck then died and would not stop. Pushed it into the parking lot and had it towed to Billy Navarre Chevrolet, Lake Charles, LA. After they looked at the truck on Jan 9, they said the engine was seized and we needed a new one. They couldn't say why. They said that would be figured out when the old motor was shipped back. After putting in the new motor, the POC at the dealership called and said we needed a new water pump that the one he took off was bad. They insinuated that was the cause of the engine seizing. However this wasn't determined until they went to put the old one on. If the water pump failed, we believe it should have started showing engine overheat and there was no such thing.

Engine seized it won’t crank we swapped the alternator 2 times the battery once the and the starter once we also swapped the battery chip 3 times and it would turn off out of no where. We thought it was because of the miles but it was working fine. And took care of it nicely. We took it to a dealership and they told us that it needed a new motor because it was seized. But before that it would start up and turn off after 15 minutes. We took it somewhere else in a tow truck and they told us that the engine was seized.

ENGINE
while driving down the road i noticed the truck had a lack of power and then the check engine light came on and as soon as it came on i heard a ticking/clacking noise. I got the truck towed to a repair facility and they found misfire on cylinder 8, they informed me and wanted to drain the oil and also removed the valve cover in order to check the valve train. They found a lot of metal in the oil along with a decent amount of decent shavings in the oil filter. They removed the valve cover and found a bent pushrod and stuck lifter. They did mention a possible noise coming from the bottom end of the engine (knocking) but at this time with the amount of contaminates in the oil and stuck lifter, The engine is recommended to be replaced. No ETA at this time for a replacement

POWER TRAIN
Transmission has had shifting, shudder and failure to go into gear from day 1 of owning the truck. Has been to the dealer on several occassions for the same issue just to be told that they either could not reproduce the issue or it was normal. On another occasion the dealer was able to notice some shudder and shifting issue and replaced the valve body under warranty. Now that the vehicle is out of warranty I’m being told the vehicle needs a complete transmission rebuild and torque converter at an out of pocket cost to me of $8500. I know of many others with the same issues from the onset of owning these vehicles.

I was driving down the highway with my teen daughter heading to a hockey tournament in Michigan. We live in Illinois. While in Michigan on the highway driving around 80 mph, I went to pass a vehicle and several service warning lights starting flashing on the dashboard. The ones that flashed were: Service ESC, Service Parking Break, Steering Assist is Reduced Drive with Care. At the time, the engine started making rattling noises and sounded rough. I could feel there was a problem right away. I carefully pulled over and turned the truck off. I waited a few minutes and then turned the truck back on. The service warning lights were still on and the engine was still running and sounding rough. I tried turning it off and on again but the same problem persisted. I then drove the truck about one mile to the next exit just to get off the highway. I was doing about 45mph during this time. I then pulled into a parking lot and contacted On Star to diagnosis the vehicle. They diagnosed a P300 code and said it was an engine misfire. I then found a local repair show and drove another 2 miles to get there. They looked at it for an hour and said they could not help me. They were also getting the cylinder misfire code. I had the vehicle towed to a dealership that same day. I had to rent a car to return back to Illinois with my daughter. After a week and a half, the dealer started looking into the issue. They diagnosed a lifter failure and said a new engine was needed. We purchased the new engine for $10,490 and the dealer installed it. Three weeks later, the vehicle was ready and we had to drive to Michigan to pick it up. I’ve reached out to GM and they just apologized and offered us 15,000 points in our GM account. We declined. We asked for financial assistance and they also declined and said it was out of warranty and it’s our responsibility to pay for all costs.

The truck engine experienced catastrophic failure while driving at 30 MPH. There was no warning or dashboard indication problem prior to the failure. Loud ticking noises were coming from the engine compartment just before full power loss while driving. The vehicle was towed to an independent mechanic. The mechanics found bent valves, damaged pistons and connecting rods. The mechanic replaced the the engine with a GM Longblock. The cost of this repair was just over $10,000.
