Electrical System Problems of Chevrolet Silverado 1500 - part 1

I am having the same issue as the gm safety recall n232426400 - where it says it is a common issue in 2020-2024 chevy 1500's (which my truck is a 2022 chevy). Where the tailgate will drop by itself. I looked into this recall and my truck is not included. However, it just rained heavy and now my truck's tailgate is dropping on it's own. This is a safety risk due to loading the truck bed and having it open on its own without me knowing resulting in items falling out of my truck onto the roadway. Another thing is my lane keeping assist is no longer working.

On Monday, 6/15/26, with approx 45,400 miles, I was driving down the road and truck said service transmission. The gears would shift, but it lagged a little bit. I scheduled an appt for two days later, and only drove it when I absolutely had to, which was only twice before my scheduled appt. I get in it to drive and it says service transmission- unable to shift soon, then on my way to the dealership, it says all of that, plus service driver assist system. Chavy's quality assurance team needs to get it together! this is absolutely ridiculous.

Over the last week, my truck power has been almost shutting down after the stabilitrac warning appears on the dash while I’m turning or going over uneven pavement. The whole system shut down once already when turning around in a driveway. I have a new battery. Spark plugs are good. Abs is good. There are no recalls I can find, but this must be electrical somehow. Help me pls before it causes an accident.

6/12/26 ( 2023 chevy silverado - 6. 2 liter engine) while driving at approximately 40 mph on a two lane road, the truck shut off. After multiple attempts, the engine failed to restart. The transmission locked up in park and would not release. This required the truck to be dragged up on the flat bed wrecker instead of rolling freely. Prior to this instance there have been several issues with the electrical system. 1. Radio sound shuts off. Does not come back on. 2. Head lights stay on for 10 minutes after vehicle is turn off. 3. Tail gate opens on it own. Tail gate doesn't open with fob. 4. Door locks fail to operate correctly. 5. When drivers door is opened a beeping sound starts and doesn't stop until door is closed. I have reported these problems to gm & have two case numbers. The dealership reports that the 6. 2 replacement engines have had multiple failures.

My 2023 Chevrolet Silverado 1500 experiences an intermittant, uncommanded mechanical drivetrain lockup and severe binding when accelerating from a complete stop. The vehicle rolls fine in a straight line for several feet, but the exact moment the steering wheel is turned slightly (a couple degrees), the drivetrain violently binds up. This creates resistance in the steering and acceleration, as well as a severe physical and audible metallic clunking slam and massive shockwave vibrations felt directly through the steering wheel, floorboards, brake/gas pedals, and driver’s seat. During the last event, the vehicle threw a "service 4 wheel drive" dash message and refused to shift out of "auto" mode back into 2wd. Because this is a pure mechanical interference/binding issue, it does not consistently throw active electronic trouble codes. A standard obd2 code scan will show nothing. After turning the vehicle off for several hours and testing again, the problem persisted. After towing the vehicle to a dealership (6/10/2026) it sat for at least 5 days before dealership service looked at it. By this time, the active warning lights cleared. My initial servicing dealership refused to perform physical hardware or fluid diagnostics under my factory warranty, stating they would not look at the vehicle unless I paid $860 out-of-pocket or until the drivetrain "completely grenaded" on the road. Because this uncommanded lockup restricts my ability to steer the vehicle safely from a stop, it presents an immediate crash hazard. At the direction of general motors corporate, I am escalating this issue and moving the vehicle to a secondary certified facility (feldman Chevrolet of novi) on June 23, 2026, for a formal physical hardware and fluid tear-down inspection.

Auto wash truck quit, dead would not restart, tow service disconnected battery and reset. Okay after. Visit to dealer service they said nothing wrong. Driving yesterday in the rain quit 4 times on the road driving, it would restart each time. Warning on the dash would flash at times "hands on the wheel" while driving ? this is a serious safety issue. Intermittent when it gets wet, new truck, 1,800 miles, no alterations. Dealer service no help, it has hard codes, can bus communication issue, water intrusion likely cause, we are afraid to operate on the road, help please.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 25 mph and attempting to depress the accelerator pedal, the vehicle lost motive power, the contact attempted to start the vehicle, and the vehicle operated as intended. The check engine warning light was illuminated. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed; however, the diagnostic result was unknown. The dealer cleared the codes, and the vehicle was then taken to another dealer, where it was diagnosed and determined that the ground strap needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the part was on back order and might take six months for the part to do the repair to be available. The approximate failure mileage was 4,000.

On June 7th, 2026, I pulled into my driveway, and put the truck in park (did not set the parking brake, but left it running). I walked, approximately 25 feet up my driveway, towards my garage, to retrieve my garbage can, to bring it to the road. About the time I got to my garbage can, my truck proceded to roll towards me, as I walked back towards the road. I then noticed it rolling, let go of my garbage can, ran to the truck, jumped in it, hit the brakes, and I had to shift the truck back in gear, then back in park. By that time, it had already struck the support pole to my temporary car port, destroyed it, and caused a small amount of damage to the front fender of my truck (small dent, and some scratches in the front plastic). I know I did not leave it in drive, as I had to shift it into gear, then back into park, as well as the fact, that it stayed still, as I walked normally, 25 feet up the driveway. I tested the truck, after the fact. It starts rolling immediately after taking your foot off the brake, from the same spot. On a side note, my truck had just received an update download, 2 days prior to the incident. There were no warning lights. Luckily, my safety, was the only one at risk. I have not had it inspected, and it has not happened again, since. I did contact general motors, immediately, but got no response to my email. I do have a short security video, starting when I retrieved my garbage can, to the moment the truck struck the pole.

Engine failed and no light or warning besides check oil was shown on truck. The electrical system also went out (a year before engine failure) so car wouldn’t start.

The vehicle experiences a recurring electronic and sensor failure where critical advanced safety systems completely shut down while driving. The dashboard displays active failures for the front collision detection system, automatic headlights, and lane keeping assistance. These sudden defects directly compromise the vehicle's crash avoidance features, nighttime visibility, and lane safety, creating a severe driving hazard. The vehicle has been taken to an authorized Chevrolet dealership for this exact safety issue more than 10 times. Most recently, all safety lights turned back on less than half a mile after exiting the dealership following an alleged repair. The authorized service center has been completely unable to properly diagnose or permanently fix these safety systems, leaving an unsafe vehicle on the road.

The rear camera view is skewed resulting in inaccurate reference angles of the vehicle. When used to assist in reversing results in improper placement of vehicle and can cause collision of vehicle with objects.

The power-unlatching tailgate drops open unexpectedly. Opened on freeway at 75mph. Known saftey recall however my VIN isn't listed as an affected vehicle.

1. An electrical failure from a component of the main wiring harness causes the ecm to respond with service esc, reduced engine power, service parking brake, service traction control. 2. Interstate driving requires maintaining rate of speed to avoid collision. The vehicle is much more difficult to drive as acceleration is very poor and also main safety functions like traction control are disabled. 3. Check engine light stays on until codes have been read. After codes have been cleared, normal driving and usually turning or bumps in the road tend to trigger the recurrence. 4. The vehicle has only been reviewed by the dealership for this issue. 5. No warnings before the failure occurs.

Rear power window defrost thermal event. While rear defrost was on the plastic connector that goes to the rear defrost of the power rear sliding window began to smoke heavily. In 2020 there was recall number n192265660 for the 1500 series of the same year for the same component that failed and is a fire risk. 2500 had no recall but this vehicle contains the same product and poses the same fire risk as the 1500.

“service transmission now unable to shift soon” message. Vehicle is stuck in park. Message appeared in may. Transmission stuck shortly after. Safety is at risk due to transmission being unable to shift due to faulty module that is widely reported and known to Chevrolet.

The truck dies when you turn the steering wheel all the way. When that happens the steering wheel jerks and could cause a crash. This appears to be a common electrical problem that currently has no recall from the manufacturer.

Tailgate opened on its own while driving down the interstate. Since then, anytime I open a door or use the drivers door to unlock the truck, the tailgate drops. The button on the tailgate does not open it, I have to use the fob. I frequently carry construction materials in the bed, the tailgate dropping on its own with can put others at risk for serious injury or even death. No warning lamps, have not brought to the dealer, there is a recall for this issue, but my VIN doesn't match.

I purchased this vehicle from ghent Chevrolet in greeley colorado, since I have owned the vehicle I have had several transmission problems which caused the vehicle to stick in fourth gear and I have also have issues with the transmission violently shifting into first gear to the point it feels like I’ve been rear ended. I have had to replace the entire wiring harness and the water pump module as well as the thermostat module and the louvres in the front of the vehicle. I have service records for the vehicle for all the repairs and that state the amount of repairs has far exceeded the value of the vehicle and I’m currently having transmission issues again. Please help me find some sort of resolution to this situation! I have already tried to use and was rejected from the colorado lemon law.

2025 Chevrolet silverado crew cab, VIN [xxx] , purchased new in April 2025. Total transaction value exceeded $50,000 including trade in of previous vehicle. Has experienced repeated serious electrical failures in under a year and 16,500 miles. Components that failed: telematics module causing parasitic battery drain, DC/DC converter module, radio, and two complete battery failures. Turn signal was also triggering the high beams to flash, a separate electrical issue repaired under warranty. All components are available for inspection upon request. Safety risk: first battery failure occurred in January at 10,000 miles while traveling in the desert with my wife and infant son. We were stranded with no Chevrolet dealer accessible. Second battery failure occurred at 16,500 miles. A failed DC/DC converter module was discovered immediately after the latest round of repairs when the dashboard lit up with multiple warning lights and a check engine light the same day I picked up the vehicle. I drive this truck daily for work and transport my young child in it regularly. Repeated unexpected failures create a serious and ongoing safety risk. Confirmed by dealer: yes. George Chevrolet confirmed and attempted repairs on the telematics module, DC/DC converter module, and radio. All failures documented on official repair orders. Warning lamps: yes. Multiple warning lights and check engine light appeared immediately upon pickup after the most recent repairs. Manufacturer response: general motors denied my repurchase request despite multiple confirmed warranty failures and has not offered a replacement vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am writing regarding an ongoing and serious issue with my 2026 Chevrolet Silverado 1500 rst 2. 7l that continues to occur despite multiple visits to the dealership. Recently, as I was leaving my house, I entered my truck and started the vehicle as normal. Immediately after startup, approximately eight warning lights and system failure messages appeared on the dashboard simultaneously. The warnings included the check engine light, abs warning, brake system failure, service steering column lock, service traction control, service esc, service brake pad monitor, and trailer brake disabled warnings. At that point, the truck became undriveable. Although I was able to shift gears, the vehicle would not move properly in either drive or reverse. Due to the severity of the issue, I turned the truck off and left it parked overnight. The following day, all warning lights and messages had disappeared completely. This situation is extremely concerning because the vehicle appears to fail randomly without warning. I no longer feel safe driving the truck, especially with my children in the vehicle, because I fear it could stop functioning again at any time and potentially create a dangerous situation. I have already taken the truck to the dealership multiple times regarding this issue. However, I have repeatedly been told that they cannot properly diagnose or repair the problem unless the warning lights are actively present at the time of inspection. Since the issue is intermittent, this has made it very difficult to get the truck repaired, even though the problem clearly continues to occur. I am requesting that this matter be taken seriously and investigated further, and because this is a new truck that barely has 7,833 miles on it. As this appears to involve critical safety systems including braking, traction control, steering, and vehicle drivability. I depend on this truck daily and need a permanent resolution to this problem as soon as possible.

The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 21,800.

Had a vehicle update for my 2023 Chevrolet silverado and now my onstar module is toast and no longer under warranty bc I have 37,000 miles. Many reports of this happening to 2023 models but no recalls for this. Why should I have to pay $1000. 00 for a part that is failing in many vehicles of the same year.

2026 Chevrolet Silverado 1500 safety issue summary: I am filing a complaint regarding critical safety defects with my vehicle.

The contact owns a 2023 Chevrolet silverado. The contact stated while driving at approximately 40 mph, the vehicle stalled, the brakes were inoperative, the gear shift was stuck in drive, and all of the doors and windows were locked and inoperative. The check engine warning light was illuminated and the "please restart the engine" message was displayed on the instrument panel.

The failure mileage was approximately 373200.

The rear park assist will randomly turn itself off. It happens while just driving down the road and also at times when backing up. This has been an ongoing issue since I took the truck in to get the chips installed for it to work.

The micro switch that tells the truck that it is in park is not working. So when the truck is put in park the display says vehicle not in park and dings. This started at only 48,000 miles intermittently but is doing so constantly now at 53,500 miles and I’m having to buy a part to replace it.

While driving at approximately 45 mph, the steering system suddenly failed without any warning. The steering wheel became extremely stiff and nearly impossible to turn, resulting in a sudden loss of control of the vehicle. I was unable to safely steer, especially when attempting to turn right, which nearly caused a crash. There were no warning lights, alerts, or prior symptoms before this failure. The issue occurred abruptly and without any indication, creating a serious and unexpected safety hazard. Due to the severity of the problem, the vehicle had to be towed and is unsafe to drive. This appears to be a failure of the electronic power steering (eps) system. A sudden loss of steering assist at driving speed presents a significant risk of injury or death to the driver, passengers, and others on the road. This is a critical safety issue that should be investigated immediately.

While driving truck loses power. We stop put in park & then have to restart the truck to start driving. It has happened 3 times & we know this is a problem for other trucks.

In 2024 there was a recall for the tailgate locking mechanism - we did not receive that recall - but the part went bad causing the battery to drain - and it had to be repaired. We had to pay for the service $500. 00 - we I asked the dealership about this recall they said it did not include my vehicle. But it was indeed that part that went bad. I lease the truck - I had every intention of purchasing after the lease - I am over the miles and was told it was out of warranty. I certainly would not complain about paying for it - but there was a recall last year for said part. Could some please reach out to me regarding this - thank you.

The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes p0700 (transmission control system malfunction) and p0717 (input speed sensor circuit no signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "reduced power / limp mode. " this creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision. The malfunction has been repeatedly confirmed and documented by authorized gm service agent rountree moore Chevrolet (lake city, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including transmission control module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the failure confirms the dealer has been unable to successfully remedy the defect. To date, the vehicle has only been inspected and worked on by the authorized dealership's factory-trained technicians. It has not yet been involved in a collision requiring police or insurance representative inspections, nor has a corporate field engineer from general motors inspected it outside of the local dealership level. The failures are consistently preceded by an illumination of the dashboard check engine.
