Electrical System Problems of Chevrolet Silverado 1500 - part 2

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.

Wheel will lock up randomly on slow turns like an intersection, parking lot or anything. It’s very random and there’s no reason why it does it. The truck drives fine most of the time. It will say stabitrack service on my dash then it will go away my wheel locks up so I can’t turn it anymore then it will release like 10 seconds after. I nearly been in two accidents from this. The dealership can’t find out what’s wrong with the truck and I don’t feel comfortable knowing it’s not fix.

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.

Vehicle is experiencing intermittent electrical issues, including vehicle completely shutting off while driving, driver window security warning message appears, radio, outside temp and fuel economy will reset when starting the truck. Last time it shut down while coming to a stop, a message appeared on the driver information screen saying “3 key programmed to vehicle”. Sometimes before it shuts down while driving, the radio and dash lights go out followed by engine stalling and there are different messages that appear briefly, like, service stabilitrac, roll driver window down & 3 keys programmed. The truck has shut down on me while operating 7 times in the last 3 months! this is extremely dangerous as I lose power steering & brakes! it has happened while in the middle of a busy intersection, in a round about, pulling into a parking spot, driveway and while driving straight on a road. I have cleaned & checked all ground locations, replaced the battery and alternator, cleaned battery terminals and cables, checked all the fuses and nothing has made it stop!.

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.

This truck is locking up momentarily, sometimes at high rates of speed on the interstate. It is very violent and jars the neck of my and my passengers. It leaves tire skid marks on the highway at high rates of speeds. It happens when I slow down or when the truck tries to shift gears. Turns out, gm has a recall for this exact issue, (n242454440) but my VIN is not included for some reason. The chevy dealer has confirmed this issue and is recommending a new transmission. This has been ongoing since July and I am on pins and needles every time I drive this vehicle. Can you please encourage gm to include my VIN in their recall: n242454440, holding me harmless for the repairs?.

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.

It’s throwing multiple codes for the bcm(body control model) and it’s show recall numbers 15v640000,17v43700 and 14v301000 are multiple recall numbers showing fro a bcm 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.

Vehicle started and behaved as expected when leaving my home and for a dozen lights or so between my home and place of the incident. While stopped at a red light, the auto stop function shut the truck down as normal. On re-start when getting green light, after releasing brake pressure, the start up was belabored for two turnovers before starting up. As I pulled off the stop with a green light, the dash lights illuminated and display started rolling through system failures, one of which was the brakes system and esc. I cautiously proceeded through my turn to a thankfully quiet intersection as the brakes were completely unresponsive. I had zero brake function. I was able to slowly come to a rolling stop enough to get the truck in park where I turned it off and back on and the brake function returned. I cautiously drove to the local chevy dealer where I was informed that the battery drain pulls from low voltage when it needs extra power for start up. This is utterly terrifying that it is even possible for the battery to start the truck without any brake function. Had this happened just two lights before or after where I was, it would have been a news headline. I could have easily been headed up and over a bridge leading to a catastrophic event at the bottom where I would have been completely unable to stop my truck by any means other than a collision. I would have preferred a dead battery at a red light. Seems a whole lot safer. I'm now stressed beyond measure at the thought of some failure in the future that could lead to another event such as this. My truck is now a nightmare wondering what electrical malfunction is going to put me and/or my wife and daughter in a life or death situation, let alone others on the road. This shouldn't even be an option for the truck to start at the expense of a critical safety function. Not to mention there is no function for the auto start stop system to be deactivated permanently by my choice. I am beside myself and scared to drive.

Transmission issues already had one replaced 5/9/24 having issues again going to be 3rd transmission also having issues now with electrical system going out while driving and dinging noise,when entering or exiting vehicle here rebooting system whining. Going to contact car coverage to have vehicle inspected again for the problems.

2022 Chevrolet Silverado 1500 multiflex tailgate main tailgate unlock/open button has stopped working. The dealership (marine chevy jacksonville nc)stated that they have had to replace alot of them even on the 1500 series. They are now on back order with no expected availability date. Yes my vehicle is available for inspection. Requires the use of the key fob to unlock. I do not know why it has stopped working is it a wiring issue? if it is a wiring issue it should not go out on a vehicle that is less than 3 years old. Also could this cause other electrical issues.

I have a 22022 refresh Silverado 1500 high country with 12,500 miles that gets a "service transmission" warning and kills the engine leaving it in the traffic. When trying to restart the truck it just keeps flashing errors and can't be restarted for about half hour. This has happened twice to me so far. The codes recorded are in the attached file.

The vehicle began knocking on the freeway and experienced a loss of power. It caused warning lights for the electronic traction control and parking break system to light up.

On June 10th, 2025 the automatic tailgate on my 2023 Chevrolet silverado began opening and closing without reason. This obviously poses a potential safety issue. After investigating, I found that there is a recall on 2020 to 2024 silverados, recall # n232426400. I called penske Chevrolet in indianapolis to schedule a time for them to confirm the tailgate switch short and execute the recall service. I was informed by penske that my specific VIN was not included in the recall. This is not acceptable. Reporting indicates there are a number of other silverado owners in the same position. Please investigate, as the current state of the recall is most certainly not inclusive of all vehicles that are affected. There should be no hesitation by Chevrolet to broaden the recall.

1. The components that failed were the transmission because the vehicle was driving and continued to slow down until it came to a complete stop gradually, and had to be pushed home. And also, there was an issue with the doors unlocking on their own and all windows rolling down by themselves. 2. The safety risk was the issues that happened without any knowledge of any issues at all with the vehicle. And the vehicle could have stopped on the highway, and another vehicle could have run into it, and it could have been a very bad incident. And with the doors unlocking and the windows rolling on their own could be exposed to unsafe environments and possibly theft of the vehicle or harm to the occupants. 3. Had a scan done, which showed the issues that were going on with the vehicle 4. I haven't had a chance to have it taken to the manufacturer because it broke down, and I was waiting for some help to get these issues repaired from the manufacturer. And needed from acc. 5. There wasn't no indicators or lights on when this happened? I was told by a coworker about the windows being down, and with further investigations, I found the doors were unlocked as well, which was done automatically without my control.
