Electrical System Problems of Chevrolet Silverado 1500 - part 1

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that the vehicle failed to start. The vehicle was taken to the local dealer, where it was diagnosed and determined that the battery needed to be replaced. The vehicle was repaired on two occasions, but the failure persisted. While attempting to open the trunk, the trunk failed to open. The manufacturer was not contacted. The failure mileage was approximately 500.

Vehicle will cut off as if an electrical short and the service stabilitrak indicator will flash on the dashboard along with warning chimes. This has happened several times at low speed (1st gear) especially while turning. The steering wheel locks and can not be turned. I've almost been involved in an accident this week because the truck turns off while making a turn. I was at a stop sign waiting to turn left having to cross 2 lanes of on coming traffic and when I accelerated the trucks electrical cut out and forced the steering wheel to go straight I gave it more gas and the truck turned back on. On another day I pulled up and put it in reverse turned right and the truck shut off I had to put it in park and restarted it to back in my driveway. Gm need to fix this.

Truck was intermittently losing power steering and shutting off/reseting itself. Was a loss of electrical and was throwing stabilitrak service warning. Would not stay on due to truck resetting itself but loss of power happened typically when I was in parking lot or driveway. Could have easily been on the highway which could have been deadly. Dealership found that the battery cables and module were not getting enough power to truck. Replaced these and it seems okay now. Total cost was ~$1200. I see several recalls for battery cable issues but nothing pulling on my 2018 Chevrolet Silverado 1500 ltz crew cab.

The vehicle was a service loaner provided to me but it was factory new with the sticker still on the window. The dealer told me they would still sell the vehicle as new. When I started it, I had a display screen that indicated it was in a demo mode. Taking it out of demo mode would have required me to confirm that I had purchased the vehicle. The volume control and power control for the audio were not working at all. The volume was probably at 30% where I could hear but not clearly and also just loud enough that I couldn't hear sounds outside the vehicle well. This condition was not affected by the audio source. I could no change the volume in bluetooth, am, fm, xm, or phone modes. I also could not turn off or mute the audio by pressing the power button. There was a responding fire truck behind me on the road and I went to turn off the audio to hear it clearly and I was not able to. I took a video of this condition happening multiple times as photographs don't help to demonstrate much. I did notify the dealer by sending the service manager a text message with the video and said he would notate the condition. This persisted through multiple days and multiple restarts. After approx. 4-5 days, the expected functionality returned with no action or updates that I am aware of.

The trailer brake controller goes off and on. A message in the truck reads trailer brakes off, trailer brakes on, check wiring. Repeats every 45 seconds or so. You never know when you have trailer brakes or not. Did not have trouble prior 3 years with a different truck? I saw 2022 trucks had a safety recall but my VIN was not included, which it should have. Very dangerous.

While I was driving, my steering wheel was locking up, my dash lights were going off and on, and while my truck was on I wasn’t able to steer. It happened twice that day.

Issue is based off of this service bulletin, but gm has failed to call a recall on this for coverage. I was driving my daughter to softball practice. Every few minutes there would be a "stabilitrak" message showing on the driving information area. Then in slower speeds my dashboard screen would blank out and then go back to carplay. Then once I approached a parking lot at slower speeds my vehicle lost total power and shut down. Then had to switching the gear to park, then turn off the ignition key, then wait a few seconds and turn the key on to start the truck. It started as normal and was able to park in the parking space. Very scary and this is a very serious issue, I could have been in an accident with my daughter. This has to be addressed, I can't be the only one having this issue.

Am writing to formally report a transmission failure in my 2020 Chevrolet Silverado 1500 and to request your assistance in addressing this issue. I purchased the vehicle on September 2020from suburu cobband it currently has approximately 143,000 miles on the odometer. Recently, the truck began experiencing serious transmission-related issues, including total failure. These issues developed without warning and have rendered the vehicle unreliable and unsafe to operate. After inspection by alm chevy, I was informed that the failure likely stems from a known issue with the torque converter or transmission valve body — problems that have been widely reported in 2020 silverado models with the 8-speed automatic transmission. I have also learned that gm issued a recall for certain 2020–2022 models due to excessive transmission valve wear, which may cause the rear wheels to lock up. I am concerned that my vehicle may fall within the scope of this recall or a related technical service bulletin (such as TSB 21-na-199). Given the seriousness of the failure, the relatively low mileage, and the widespread nature of these transmission problems, I believe this may be a defect in materials or workmanship. I respectfully request the following: confirmation of whether my vehicle is subject to any open recalls or service bulletins relating to the transmission. A warranty or goodwill repair of the transmission or related components. If parts are unavailable, an estimated timeline for repair or alternative transportation options. I am attaching copies of my repair estimate, service records, and proof of purchase. Please advise me of the next steps and whether further documentation is needed. Thank you for your attention to this matter. I look forward to a prompt resolution so that I may safely return my silverado to the road. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

General motors is selling vehicles that are unsafe, unreliable, and unfit for consumers. My experience shows a clear pattern of negligence, misrepresentation, and disregard for public safety. On or about April of 2021, I purchased a 2021 chevy silverado rst z71 from vetter chvrolet for about $56,000. Gm promoted this vehicle as safe and dependable. Within the short 4 years of owning this truck, I faced major failures: engine issues, transmission problems and electrical malfunctions causing the parking break to engage on its own, at highway speeds of 70-80 mph on which nearly caused a serious accident, and failed electronic stability control (esc) system. This system helps maintain vehicle control, and a problem with it can affect braking, steering, and handling, despite following gm’s maintenance guidelines, gm delayed repairs, denied coverage on certain failures, and left me with thousands in out-of-pocket costs. The vehicle remains unreliable and unsafe. For myself and my family, 2 children under 3 years old and one on the way. This is not an isolated issue—gm has a long history of recalls and defect cover-ups. These vehicles put lives at risk, cause financial hardship, and violate consumer trust. No one should fear for their safety in a vehicle marketed as “dependable. ” this has impacted me by having : • expensive repairs • loss of transportation for extended periods • ongoing fear of driving a defective vehicle with my family in it. Loss of use of my vehicle • fear and emotional distress driving an unsafe product I have contacted gm and the dealership multiple times. Responses were dismissive, repairs were inadequate, and gm refuses accountability. Requested resolution: full reimbursement for all related costs buyback (preferred) of the vehicle or permanent repair at no cost public acknowledgment and stronger quality control. Warning to consumers: think twice before trusting gm. Their failure to correct dangerous defects shows profits matter more than safety.

When my speed decreases to slow for a turn, traffic, red light,etc-I lose complete power in my entire vehicle. A too fast message pops up on dash about stabilitrak. If I throw it in neutral fast enough it’s fine, but if I don’t, my truck loses all power and I have to open and close my door, restart my truck, the dash tells me to open and close my driver window, and it drives again but my time and date restarts on my dash screen like I disconnected the battery. It doesn’t happen every day. But when it does, it’s scary because I can’t get out of the road. This occurs unexpectedly several times a month for the past few months. I’ve checked for loose battery cables, etc.

Truck experienced reduce power mode. Took to have codes ran and it showed 24 separate codes when engine light comes on. While riding down the road, truck will go into reduce power mode, shift automatically into 4x4, and several other notifications will appear. Taking to dealership and was told the electrical wiring harness was shorting out causing this issue. Cost around $700 for repair, happened one month later, took it back and no charge for the 2nd time. It is currently in reduced power now. Dealership stated to replace the wiring harness would cost over $3,000. Dealership stated this was a manufactures defect, but no recall was issued so all cost is on the owner.

I was driving down the road at speed when the gauge cluster lost power and reset, the truck jerked violently. A couple days before the truck lost all electrical power (lost gauges, door locks, interior lights, door locks and ignition) while idling.

When attempting to park the truck and shut the engine off, a message appears on the dash stating that I should "shift to park". I have already made the shift to park but the system will not allow the electrical system to shut down. A loud beeping begins, door locks remain open and inoperable, the vehicle is then unsecurable and the ignition remains open/on which in time will run the battery down. Disconnection from the battery will stop the drain on the battery for this particular event but will not cure the problem nor erase data that has sometime worked on complex computer controlled devices. I refuse to allow my wife to take the vehicle to park at any location for fear of her safety to secure or lock the vehicle and, in the event she would have to vacate the vehicle it would increase the possibility of theft of the truck. Gm has recalled other makes of their products for the same problems which I understand was also reported to NHTSA and has also suffered litigation in the form of class action suits which was won by consumers in the states of tennessee and ohio. After consulting the dealership with the complaint, I was instructed that gm has not issued a recall for these trucks which experience the same problem as those they were required to recall and repair. The costs for such repair by the consumer is unreasonable and unwarranted by reasons that this is a manufacturing and certainly a safety problem for the consumer. Their disregard for safety and quality control has been demonstrated continually as research in this matter and other complaints of gm problems are and continue to be numerous. This vehicle is is out of the normal warranty range. However, just as the problem with the brakes that suddenly failed just after the warranty expired on this vehicle which was also a major safety problem, extensive testing of gm safety performance is not a priority but rather they ship it out the door to consumers and just see what happens. Thanks you for your time. [xxx] information redacted pursuant to the freedom o.

While driving without a trailer attached to the truck or anything plugged into the trailer plugs on the truck, the "service trailer brake system" continuosly flashes up on the dash and chimes even after mutiple "dismiss" attempts it still comes back.

Vehicle will cut off as if an electrical short and the service stabilitrak indicator will flash on the dashboard along with warning chimes. This has happened twice at highway speed (65mph) and several times at low speed (1st gear) especially while turning. The steering wheel locks and can not be turned. I've almost been involved in 2 accidents this week because the truck turns off while making a turn. Also the mylink infotainment system screen has gone completely blank while driving. Although functioning, the displays comes on and off. This has happened off and on for 3 months.

See attached document for complaint.

07/28/2025 10:35am, we had just pulled onto an interstate ramp and the engine powered down and the dashboard began flashing errors, service engine soon light came on. The following errors were displayed: reduce speed to 62 mph, brake system failure, service traction control, service esc, service steering column lock, trailer brakes disabled service required. I had no brakes and had to pump them to get stopped. I was able to pull to the side of the road and shut off the engine. I called dealer and reported issue as this occurred last Tuesday. They advised to bring the vehicle in at 0800 tomorrow. I restarted the vehicle and system reset and I was able to continue. At 12:58pm, I pulled off the interstate ramp onto a county road and the engine powered down again and displayed the same errors. The brakes did not fail this time and I was able to get home.

I was driving on the interstate at speed when the dash cluster stopped responding. All gauges went to zero including rpms and speed. I was unable to determine if the engine was still running. The cluster was out for about 15 seconds and then began working again. By the time I had maneuvered to the side of the road, everything was normal again. The same failure happened a few days later.

Tailgate experienced issues with not unlatching when button is pushed and also unlatching when button is not pushed.

Windows motor shorts out. If driving vehicle cuts off in order for window motor to reboot. Once you cut back on, error code tells driver to role window down and then back up.

There is no sound from the entertainment system, this happens randomly about once a week. The safty concern is that when this happens there is no sound for anything including directionals, other warnings and this can cause a safty issue. The only way to have the system work again is to shut the vehicle off for ten minutes and restart. My vehicle has had the software updated at the dealership about every three months since I purchased it, and to no avail.

I went to drive my truck and it would start but I got a “ service power steering no assist “, service rear vision camera, service trailer brake system. Then it wouldn’t start and got the “ lost communication with fuel pump control module, back up camera was flashing in and out and license plate lights would flash with turn signal on.

I have had to replace 2 batteries due to the tailgate opening and shutting randomly even when parked, and ruining my batteries. You recalled the 1500 hd's for the same issue. . . But yet not this model when it's clearly happening to 1000's. I'd appreciate it being fixed.

My 2025 chevy silverado zr2 has experienced the same dangerous system failure five times. While driving, every warning light on the dash activates, I lose power steering, and the vehicle completely shuts down and won’t restart. This creates an extreme safety risk — the first failure happened on a local road, but most recently, it occurred while my family was driving out of state during a holiday. The truck has now been out of service for over 50 cumulative days across these repeated incidents. Gm has accepted a lemon law claim but has not resolved it, leaving me without a vehicle and no clear path forward. These systemic failures present serious risks to me, my family, and other drivers. The latest failure occurred in July 2025, and the vehicle remains at bill cramer Chevrolet in panama city beach, FL with no resolution. I am still making loan payments and paying for transportation out-of-pocket, without any support from the manufacturer.

What component or system failed or malfunctioned, and is it available for inspection upon request? the ecu/power train failed/ yes the vehicle is available for inspection. The vehicle's check engine light & traction light came on & the dash displayed multiple warning messages including reduced engine power & service ecs. How was your safety or the safety of others put at risk? I was traveling on the interstate at 65 mph in traffic in the far left passing lane. Engine power was reduced & I had to safely navigate the vehicle through traffic & multiple lanes to safely get the vehicle to the shoulder of the interstate & avoid causing any accidents. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the problem was confirmed by my local Chevrolet dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? it was inspected by my local Chevrolet dealer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no there was not. The issue was attributed to a known manufacturing flaw on my vehicle. The wiring harness to the ecu was chaffed caused by rubbing on the frame, ecu bracket and/or a arm which in turn caused the issue. Gm published a repair bulletin on this issue as well as the NHTSA.

Service trailer brake message constantly displays on the dash. But I don't haul trailers.

There is an issue with the wiring harness that causes vehicle to lose power. Dealership says manufacturer defect because designed with harness cover is too thin and is to close to engine so burns wires. Many other users have complained of this issue and is frequent in this model.

At low speeds and turning right or left the steering wheel locks up if wheel is turned quickly and engine quits momentarily, power is lost to instruments and radio, etc. Or in one case the vehicle has shut off completely. I saw that there was a recall for this on earlier models but not for my VIN (2016 Silverado 1500).

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at various speeds, or while attempting to reverse, the infotainment system displayed a blank screen; however, approximately a minute later the infotainment screen displayed as intended. The contact stated that the radio became silent and then thirty seconds later the infotainment system operated as intended. A dealer was contacted. The vehicle was taken to the dealer where it was determined that the infotainment system needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 44,540.
