2023 Chevrolet Silverado 1500

On 4/09/26, while visiting friends near the border in [XXX] from [XXX] and driving on a dry paved road we lost the ability to stop the truck and engage the brake system. To avoid a crash, I drove the truck up onto the sidewalk and closed my eyes. Fortunately we did not crash into stopped cars but the truck does not work and it has body damage to all sides. Now when the key is in forward collision system unavailable, service traction control and service ESC shows on dash. Truck is unsafe and a hazard on the road. A call to GM has been made waiting on a response. Gm case#XXX. Truck is 2023 with 62k miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The adaptive cruse control will apply the brakes driving, it happens when driving and there is nothing in my lane as far as the eye can see. Sometimes the Silverado will go from 70 mph to 30-40 or less and back to 70. Most of the time it will apply the brakes for a sec and then off. One time it locked up the brakes from the low 60 ish MPH to almost stoped before I could get control. Every time this happens there is no cars, or abstractions in my lane. I have had the Silverado into 2 dealers for this problem about 25 times and they can not fix the problem and I have been told that they are done working on it and they can not find the problem and I will have to live with it. I don't fell safe driving it and have told that to them. I have asked many time to have a GM Engineer look at my Silverado and find the problem and they did nothing to resolve the problem. I need to a get this problem addressed before I cause an accident or am in one. I also have many other problems that they cannot resolve, The Blind spot mirrors light will go off all the time with nothing there or a car will pass on the left side and both the left and right mirror lights will go off. The Bluetooth will disconnect from the Silverado and the person I am talking to can hear me just fine and the call is no longer over the speakers in the Silverado it is on the ear piece of my phone and then will go back to the speakers on the Silverado. I will get an alarm that says "Take Wheel" with hands at 10 and 2 on steering wheel looking straight ahead. Get an alarm that have trailer light problem and will turn on blinker and it will flash quickly for 10 seconds and then is normal. Radio skips on FM, AM, XM, MP3 Player at times. The Silverado has spent over 4 months and 25 times at a dealer since I bought it new and they have nor been able to resolve any of the problems and I have been told by GM that they are done working on this truck and they can not find the problems. Thank You

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while stopped at a traffic light, the engine turned off and the instrument panel became inoperable. The vehicle was restarted; however, the failure persisted. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that on a separate occasion, the message "Tailgate Open" was displayed on the instrument panel. The contact pulled over to the side of the road and, upon inspection, noticed that the tailgate was closed. The vehicle was taken to the dealer; however, no cause for the failure was found. An employee at the dealer closed and opened the tailgate several times until the message disappeared. The contact stated that on a separate occasion, the radio stopped functioning, the driver's door unlocked unintendedly, and the driver’s side seat belt failed to retract as intended. The vehicle was taken back to the dealer, where it was diagnosed that the seat belts had failed. The contact seat belts were replaced. Most recently, there was an abnormal sound coming from the engine. In addition, the brake pedal was depressed, and the vehicle failed to respond. After a while, the vehicle was able to stop. The message "BRAKE System Failure” and “Replace Brake Pads and Rotors" was displayed. The vehicle was not diagnosed or repaired. The contact stated that the failure persisted. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 22,000.

I am sending this email to report that my 2023 Chevrolet Silverado had its rear brakes lock up momentarily on consecutive days (1/13/26 & 1/14/26) driving 70-72 mph.  Each occurrence came on without warning and only lasted a brief moment, but locked up hard enough for my rear wheels to screech and slam me forward in the truck, thankfully there were no other vehicles near me. I took the truck to the dealership first thing in the morning on 1/15/26 to be informed later that day that the truck didn't show any codes.  The service department at my dealership contacted the TAC Dept. at GM and they determined that the problem was caused by the brake light wiring from my truck topper (that was after they asked if the customer had added any accessories to the truck).  I have had the topper for 3 years without any issues.  I reached out to the company that installed the topper and the owner said that GM is giving me the run around and trying to point the blame elsewhere. He himself has installed 100's of toppers and they follow the wiring instructions from Leer Toppers. He did a 30 second Google search and said [XXX] , the problem you have experienced is well documented online, GM knows what the problem is with your truck". My truck was at the dealership for 5 days before they released it to me, even after I told them that there are known and documented cases of their trucks experiencing momentary rear wheel lockups. I have called GM Customer Service twice and left messages regarding my truck and TAC # and haven't received a return call. I am fearful that when this happens again and if it does so in the wrong place at the wrong time the end of this story may be tragic.   If I was pulling a trailer, driving on ice or in rush hour traffic I can't imagine the outcome. GM knows they have a serious problem and they is comfortable in releasing a dangerous truck back onto the roads.

On 1/21/26 traveling on a 4 lane divided highway, vehicle stalled, several warning lights came on and vehicle came to a complete stop in driving lane. Vehicle locked in park and could not put vehicle in neutral to push it out of highway. Several vehicle swerved to avoid and until tow truck came blocked a lane. It was about 3:30pm fortunately. So vehicle was visible and no accidents to our knowledge occurred. Thai created a dangerous traffic situation. It was caused by a fuel pump control module Whig was repaired 2 days later at local Chevy dealer. We were advised there were no recalls on this part but it is a common problem. GM should somehow find a solution and repair said problem

While driving down the road I let off the accelerator to start applying brakes for a red light I was approaching, then the vehicle shut completely off and down shifted hard. After that it restarted a second later but had no power steering and no brakes. At this point I was approaching the red light with no brakes and power of my vehicle, the other traffic had a green light now and was crossing my lane of travel but I was luckily able to make it through the light in between vehicles without causing any harm to myself or others. After making it through the light I was rolling 10mph still helpless but seen a gas station on my right and rolled into their parking lot and drove towards a curb and used the curb to stop my vehicle. The vehicle had the following warning lights and messages: Lane Change Alert System Off, Brake system failure 62mph top speed, service traction control, service ESC, and trailer brakes disabled service required. I then got the vehicle towed to the dealership while still on and in the running position with all the codes still active. The dealer was able to scan the truck in and see the codes but told me they wouldn’t be able to get to it till the following week so they parked the vehicle and turned it off. When they got to my vehicle the following week they sent me a text and said I quote “Hey ****** its **** from Chevy, I do not have the best news lol he can not get it to act up and there are no current codes he has driven and nothing has happened, as of now there is nothing further he can do”. After receiving that text I called them to just be told they can’t get it to do it again and there is nothing they can do. But I told them I refuse to pick up this vehicle because it had a critical safety issue. This vehicle suffered a catastrophic failure, brakes and steering were lost in an intersection. If not diagnosed properly, this poses a threat to life.

GM Case#[XXX] #1 A- On [XXX] vehicle sensors disabled breaks while driving on [XXX]. B- Driver Displayed Alert. a- BRAKE SYSTEM FAILURE 62 MHP TOP SPEED. b- TRAILER BRAKES DISABLED SERVICE REQUIRED. c- SERVICE ESC. C- Concerned by alerts proceeded to exit highway, the breaks where unresponsive. This required pressing break pedal to the floor. It took over 400ft for the vehicle to come to a complete stop. Fortunately no other vehicles were on the exit ramp, a major accident was avoided. D- On 10/30/2024 took vehicle to Bomnin Chevrolet West Kendall and explained break failure and provided pictures of driver alert messages. E- On 11/1/2024, 3 days after, Bomnin Chevrolet West Kendall Technician communicated that vehicle was mechanically fine and were unable to duplicate the problem. I accepted the vehicle back with 5,901 miles of use. #2 A- On [XXX] vehicle sensors disabled breaks again while driving on Miami city street. B- Driver Digital Displayed flashed following Alert Messages. a- SERVICE TRAILER BREAK SYSTEM. b- SERVICE TRACTION CONTROL. c- SERVICE ESC. d- CHECK ENGINE LIGHT WENT ON. C- Having experienced this back in October, I knew what to expect. Unresponsive breaks, fortunately on 2nd occasion I was driving slower on a city street and was able to coast to a stop. D- On 4/10/2025 took vehicle back to Bomnin Chevrolet West Kendall for the same problem, break failure. I once again explained to Technician what happened, showed them pictures of the Alert Messages. E- Vehicle as of today, 5/18/2025, remains at Bomnin Chevrolet West Kendall for a total of 39 days and is yet to be repaired. Given the severity/danger of defective break sensors defects there is “nonconformity” that under the Lemon Law is defined as a defect or condition that substantially impairs use , value, or safety of the vehicle. These 2 incidents make this vehicle unsafe for drivers, passengers, and general public in proximity. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving going 40 mph a ‘Brake System Failure’ warning came on and brakes stopped working. Thankfully there were no cars ahead allowing me to continue until the car came to a stop. At that point I engaged the emergency brake and put the car in park and out of gear. I then had the truck towed to a Chevy dealership. I still do not have a response to what the issue is.
