It started 400 miles after I bought the truck new and was on vacation with my family, the trailer break system lights started coming on so I detached my travel trailer and took it into a Chevrolet dealership in flagstaff Arizona they couldn-??t find out why it was doing it and told me it must be the plug in the trailer it self. So on our trip we were driving threw Zion National Park when my trailer break did not engage down a steep grade and my truck break barley held enough to stop us down the grade, lucky for us the exhaust break gave us just that little bit to help us stop the truck. And now I see people on you tube showing the problem and wonder why GM has not done anything about it, I have paid many time for my truck to be fully serviced and I-??m still dealing with this broken piece.
On 10/03/21 at approximately 1251 hours, I was driving my 2018 Chevrolet Silverado which is the vehicle with the above mentioned VIN. As I was traveling towards a heavily traveled intersection in my current city, I approached a steady red signal on the traffic light. It should be noted that this particular part of the roadway is a slight decline towards the intersection and traffic control signal. It should also be noted that on this particular day, there were no inclement weather or roadway conditions that would affect the vehicle to deviate from normal maneuvering. As I applied the brakes at a reasonable distance from the stop light, almost all pressure and power towards braking was lost. As a result, I was forced to apply extensive pressure to the brake pedal as the vehicle failed to slow and stop in a timely fashion. After gaining some braking power, the vehicle and brakes began to shake and produce a clunking sound. This was troublesome because had I failed to stop in a timely manner, I or other motorists could have suffered serious injury or death as a result of a crash at a heavily traveled intersection. Prior to this incident, there were no warnings or alerts provided by the vehicle, dealer, or manufacturer about this issue. As the event occurred, an alert flashed on my dashboard that read -??Service Brake Assist.-?? Following the incident, my vehicle was inspected by a certified mechanic. Said mechanic deemed that the problem with the braking was a result of a failure of the brake booster vacuum system. After doing some research, it is apparent that other years, makes, and models of GMC products suffered the same issue with the braking system. Said issues were remediated with a recall by the manufacturer. This defect also caused numerous vehicle crashes with reported injuries.
When driving the brake pedal goes soft. In parking lots, areas of low speeds, making u-turns the brake pedal goes all the way to the floor and doesn-??t stop. The brakes completely stop working until you release and pump the brakes again quickly before hitting something or someone.

The manufacturer was made aware of the failure and informed the contact that they could not assist because the VIN was not included in a recall. The vehicle was not repaired. The approximate failure mileage was 56,500.
The DIC and infotainment both change settings on their own. It will change radio stations or call people on the infotainment and the DIC will change information displayed. The safety issue is it will also flash that the trailer has been disconnected/connected and when it thinks the trailer has been disconnected the trailer brakes will fail to function. It is a known problem with the display issue but I am unaware of any reports on trailer brake function. I have had a few serious conditions on two trailers when the truck does not recognize the trailer being connected and fails to apply the brakes.
The trailer brake control module stopped working on the interstate while pulling a 37' fifth wheel camper. This defective part caused the truck to not have any electric brakes on the camper. A warning message appeared on the dash. A new trailer brake control module fixed the problem. Since the vehicle was out of warranty (37,878 miles) the part was not covered by the dealer. The dealership where the part was purchased informed me that it was a common problem. This problem occurred while traveling at 65 miles per hour. There was only the truck brakes to stop the camper without the trailer brakes working. This is a serious problem and should be addressed.
When the vehicle was started, a loud squealing sound was heard coming from the vicinity of the front of the engine. While under the oem bumper to bumper warranted period, Chevrolet dealer number one was not able to determine the problem or repair it. Furthermore, the problem was not reported in the vehicle history as reported. A short period later, Chevrolet dealer number two was able to locate the problem and repair it at my personal expense as the warranted expired on time as opposed to mileage. I learned that the same problem was a part of a previous recall which dealt with failure of the brake assist pump. GM rectified the recall by changing the computer software to overdrive the pump beyond it's original design speed. This provided an increase in pressure which temporarily corrected the failure. The corrective action added more stress to the original design of the pump and now the pump is mechanically failing as a result. This failure could potentially cause an immediate unexpected brake failure potentially resulting in frontal collision and loss of life!. the dealers have not provided copies of service orders or replaced parts. I only have rental agreements to substantiate that something was done to the vehicle. GM's customer care is investigating the unprecedented behavior of the franchised dealers with no reply to me at this time.
Reduced power steering assist engine stall ipc / radio / HVAC goes blank various dtc. Had my head lights flickering, had stabilitrak errors, power steering errors, and the worst of all, the steering wheel jerking out of my hands.

Transmission locked up and failed. Acted like it bound up. This happened during a normal shift sequence, acted tight then engine just kept over revving. Happened about 3-4 months ago. Dealer fixed for free. Said it was common. This happened right at 60K miles. Said if it happens again they will not warranty it as there is no fix for this problem. Suggested I buy another new truck. Next problem is my right front caliper has failed twice and needed complete replacement. It is now failing for the third time. This is seriously unsafe and crazy. I have only about 73K miles on this truck. Third thing is my chrome trim on my door handles has repeatedly failed. I was told by my dealer this is normal and it is not fixable unless I pay them. It is not normal wear and tear. The truck is babied and kept in perfect condition.
ABS (trailer braking system) and stabitrak warning lights randomly come on while driving and remain on until vehicle turns off. On multiple occasions the rear wheels have locked and steering becomes difficult even when brakes are not being applied. This has occurred while driving at varying speeds and in varying weather conditions. Vehicle has been checked by dealer on 3 separate occasions for this and service was reported unable once lights have gone off. Said incident has occurred approximately 30-50 times over the past 18months.
At low speeds, such as parking lot, or traffic jam, and even while at a stop light, the brake pedal pushes up and becomes very hard. The brakes stop working and the truck must be taken out of drive. Chevy has issued a recall on Silverado trucks 2014-2018 equipped with 5.3L motors the recall number is 20V603000. Everything that happens as a result of the faulty brake assist is exactly what is happening to my 2018 Silverado (5.3L) bomnin Chevrolet dadeland and Chevy is telling me that my VIN number doesn't qualify me for the recall, yet my truck description and brake problem, both match the recall perfect. To add insult to injury bomnin charged me $630 and when I went to pick up the truck it is exactly the same. No brakes at idle.
While driving on 30-40mph and hit the brakes slowly, it feels as if the pedal is gonna fall off and can also feel a vibrate on it. It also stalls as if the brakes are being pressed but I'm not, this happens usually in the beginning after being turned on and then stops doing it after reaching the middle of the temperature.
Been having voltage issues for a couple of days where my lights dim and volt gauge drops and raises while driving or stationary dealer said it's normal also hard down shifting while driving not letting off the gas assistant brakes have failed and clunk hard sometimes when stopping or press hard back at me through the pedal again dealer said it's normal I pulled my truck out from the back of the house to the front shut it off to go get ready for work a couple minutes later my daughter informed me my truck was over heating I went to door to find smoke pouring out of my truck from under the hood grab a fire extinguisher run out pop the hood and the whole passenger side of compartment is in flames how does a vehicle that's not running start on fire? awaiting my insurance company to get it out of here I imagine will be a total loss there isn't much left of the engine bay so not sure what started the fire
I started my vehicle and put the truck in reverse to back out of a parking spot. Gave the truck gas and it wouldn't accelerate. Put the truck back in park and looked at the guages and there were no RPM's showing on the cluster and the oil pressure was at zero. There was a message that said trailer brake system on the screen. I turned the truck off and on again and the same thing happened. I put the truck in drive and it would move forward but the motor ran very rough and there was no power steering. I dismissed the first message and another message popped up that said "steering assist is reduced, drive with care." I pulled into another parking spot, turned the truck off, and waited for a ride. I started the truck when my ride showed up to make sure it was still not working and it was as if nothing happened before. The truck had no issues on the 16 mile drive home. Got home and turned the truck off and started it again and the message came back up and the issues came back. I have a video of the trailer brake system and me shifting the truck and the guage cluster. I have a picture of the steering assist message.
While driving 41-60mph, the truck starts to idle as if the brakes are being pushed on one tire and the brake pedals and gas pedal tend to vibrate as if it were to fall off. After awhile doing that, the stability control light message comes on after reaching the middle of the coolant temperature and the problem goes away. Seems like it does it when it's on low temperature.
Started having soft/hard braking issues when going at low speeds. Pump the brake petal a few times to try and apply more pressure but does not do the trick. Do not see any issue's with leaks or damage. Seen recalls for vacuum pumps with the year and model the same.
