Electrical System Problems of Chevrolet Silverado 1500 - part 1

I applied brake and pedal went straight to floor without any stopping. I had to steer into a ditch to avoid a collision resulting in more damage to steering system, frame, windshield and body. This was complete brake system failure and yes is available for inspection. I was in a very rural area at time and was able to avoid a collision however, if I had been in city or on highway it could have easily resulted in injury or fatalities. The problem is currently under federal investigation and has been widely reported as a serious problem which may soon result in widespread recall. The vehicle has not been inspected yet by dealership or anywhere else as it just happened 18 hours ago. There were no warning lights or chimes before the incident when pedal went to the floor. After incident dashboard lit up with warning lights including, brake, abs, traction control, power steering, collision system, engine light, steering column and others. Truck speed limited to 43 mph. And pedal still goes to the floor without applying brakes.

The contact owns a 2020 Chevrolet Silverado 1500. The contact stated that the infotainment center intermittently went black, and there was water leaking into the vehicle through the top and lower center of the front windshield and the rear windshield. The vehicle was taken to a dealer, where the rear windshield was replaced without a diagnostic being performed; however, the failures persisted. Additionally, the side view mirrors intermittently failed to unfold when starting the vehicle. The contact stated that while driving approximately 40 mph, white smoke emitted from the exhaust, the vehicle hesitated, and it lost power. The check engine warning light illuminated, along with "service electronic stability control", "trailer brake system", "steering assist reduced", "service brake assist", and "brake system failure" messages, and the vehicle failed to exceed 40 mph. The vehicle was towed to a second dealer, arcadia Chevrolet Buick (210 s brevard Ave, arcadia, FL 34266), where it was diagnosed that the lifter and torque converter had failed. The lifter and torque converter were replaced, and the system was flushed. Approximately 800 miles later, the engine failed again. The vehicle was towed to an independent mechanic, who diagnosed that the torque converter and transmission had fractured. The torque converter and transmission were replaced; however, the warning lights and messages illuminated again, and the vehicle continued to hesitate when driven over 42 mph. After being parked for a few days, the warning lights were no longer illuminated and the mirrors opened, but the engine hesitation persisted. The vehicle was not further diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 10,000.

While stopped at a highway red light, the vehicle jolted forward and numerous dash lights came on, including messages saying “brake system failure, service esc, service trailer brake, service parking brake, engine power reduced, power steering reduced. ” this is the first time any of these messages have ever appeared. This made the vehicle incredibly difficult to steer and the braking ability was almost non-existent. Had this happened one minute earlier or later, a multi-vehicle and potentially fatal accident would likely have occurred. Vehicle was towed to a dealer who confirmed the error messages and severely reduced performance. To me, this seems consistent with gm service bulletins pit5730 and 20-na-073. The dealer, however, is quoting me $3,700 to repair the master cylinder and electronic control braking module. Whatever the case, this absolutely needs to be upgraded to a recall before this happens to somebody at the wrong time.

The contact owns a 2022 Chevrolet Silverado 1500. The contact stated that while driving approximately 45 mph, the vehicle lost automotive power. The message "shift to neutral and restart" was displayed. The contact pulled over to the shoulder of the roadway and restarted the vehicle; however, the failure progressed. The vehicle was towed to a local dealer and remained at the dealer for additional diagnostic tests. The vehicle was not repaired. The contact stated that prior to the failure, while hauling a trailer, the message "reduced power" was momentarily displayed. The manufacturer was made aware of the failure. The failure mileage was approximately 51,000.

I went to the store and my brakes were working as normal. When I started my truck to leave I had a hard pedal and there we several warnings on the dash. One said to get service and the other said to limit speed to 43 mph. I had almost no braking power. Fortunately, I was close to home and the speed limit was 30 mph all the way home. Once I arrived home I cleared the code with my odbii scanner and the brakes worked as expected. If I was towing my boat this could have been a bad situation resulting in an accident. I haven't had the same issue in several days however this has to be a huge liability for gm. I'm sure that this is a known failure mode for gm.

Engine abruptly lost power in middle of high speed lane. I did not have enough momentum to make it to safety, totally on the shoulder, transmission locked up, couldn’t move vehicle to safety, extremely dangerous situation!!!.

This vehicle is a 2024 Chevrolet Silverado 1500 featuring a 6. 2l v8 engine and a 10 speed transmission, currently at 58,136 miles. The vehicle was experiencing a severe shudder. An official gm technical assistance case (tac) engineering case was opened on July 30, 2026 confirming a verified dfm cylinder deactivation or valve train malfunction. However, on August 21, 2026 the dealership falsified the repair log by printing ‘concern not duplicated’ to the manufacturer, while physically installing an unapproved aftermarket range technology dfm eliminator module into the vehicle’s engine harness to artificially override the factory emissions and cylinder deactivation programming to mask the mechanical failure. This vehicle is part of the active NHTSA engineer analysis ea26005, and the manufacturer’s dealer network is actively using unapproved third party hardware shortcuts to evade mandatory warranty repairs before the vehicle’s 60,000 mile factory powertrain limit expires. I called gm to report and request a warranty freeze and regional field engineer to go to a different dealership and was told they can’t freeze a warranty because the tac was closed on August 28, 2026 as resolved even though it was not resolved.

While traveling in bumper to bumper highway traffic in my 2022 Chevrolet silverado rst, I attempted to accelerate and the vehicle suddenly malfunctioned. I experienced sever loss/restriction of propulsion and the vehicle would not respond normally to accelerator input. I was able to maneuver toward the shoulder of the road while avoiding a major multi-car pile up involving innocent motorists. When I attempted to stop, I did not have normal braking ability and was unable to stop in the manner I expected. I had to use the shoulder of the highway to slow the truck down until I could come to a complete stop. This created an immediate risk of serious or fatal collision on the highway, and as I maneuvered the truck out of traffic to the side of the road. Had I been unable to reach the shoulder of the road, I could have been struck by surrounding traffic. Had this failure occured un an urban area or at an intersection, near pedestrians, or at a school bus stop- I could have seriously injured or killed people or myself. After I was able to come to a complete stop. I shut it off and turned it back on, then the truck read there was no gas left (I had a 1/2 tank). This incident is not isolated electronic glitch, I have experienced electrical malfunctions including the truck failing to start, unlocking, responding at all. This all occured after an engine replacement due to a recall. I am concerned that there are unresolved electrical and power-distribution, communication-network, propulsion or braking issues that presents a serious safety risk to myself and others. My concern is that if this malfunction occurred on my drive to work in the city, around pedestrians- it could have resulted in multiple fatalities.

This vehicle suffers from parasitic electrical drain. Is the car sits for a few days, it draws power down from the battery, which then causes the collision detection system to stop functioning.

Everything on the dash flickered and during that the vehicle started losing light meaning headlights and emergency lights, shortly after it completely stopped without any power. We were on the side of the interstate and it was very scary. There were no warning message be fore any of this occurred. There also wasn't any problems before then. We are waiting on the next business day to have it inspected.

The digital dashboard display began to flicker. Off more so than on making the dash unreadable. No speedometer, no fuel gauge, no gauges of any kind. When you received an audible notification from the vehicle, you had no way to see the message. As far as any vehicular information, you were not able to see anything.

On xxx, my Chevrolet silverado experienced a sudden, severe loss of normal braking shortly after I dropped my child off at school. When I attempted to stop at a stop sign, the vehicle would not stop normally. The brake pedal remained firm, but braking effectiveness was drastically reduced and required extreme force. The dashboard simultaneously displayed multiple warnings involving the brake/abs system, esc, steering-column lock, and trailer-brake system. Onstar generated a diagnostic/safety report identifying fault/error code p062f. The vehicle then entered a reduced-speed/limp-mode condition. I was extremely fortunate this occurred within approximately one mile of rick hendrick Chevrolet of [xxx] and with little traffic around me. I was able to reach the dealership without a collision. Had this occurred at highway speed, the inability to stop normally could have resulted in a fatal crash. The incident also occurred immediately after school drop-off. Had I used the normal car line instead of parking and walking my child inside, this failure could have occurred among stopped vehicles while children were actively exiting them. I immediately brought the vehicle to rick hendrick Chevrolet. Despite the seriousness of the event, I do not believe the cause was adequately investigated. To my knowledge, a computer/software update was performed and I was essentially told to “let them know if it happens again. ” they also asked what I was towing - nothing. I questioned whether an electrical fault or short could have caused the multiple simultaneous failures, but I am not aware of that possibility being investigated. Because another occurrence could cause serious injury or death, I refused to continue driving the vehicle and traded it in. I have now learned that the same vehicle is being offered for sale again. I am reporting this to NHTSA because I am concerned the underlying safety defect remains unresolved and could represent an early instance of a broader defect. Information redacted pursuant to the freedom of informatio.

Unknown which system failed. While driving on the freeway, truck lost power for a few seconds. Dash lights turned off and back on. Our safety and the safety of others on the freeway were at risk as we had no control of the vehicle. Have not had the truck checked for the problem. Scared to drive it. No warnings appeared.

The check engine light came on and my engine would stall sometimes, it would stall at start up so no safety issue. I took my truck to the dealer a week later where they said a wire was corroded from rubbing on something causing the issues and that it was a common issue.

The key will not release from the ignition when in park. This is all over the internet as a very big problem. People are bypassing the ignition interlock so they don’t have to leave the vehicle unattended with the key in the ignition inviting theft. Therefore while driving the ignition could be cut off and the key can come out. This is a huge safety issue. This will kill people.

On July 22, 2026 took truck to dealership for oil change and reported getting random (trailer brake, power steering) service alarms. Was told it might be a ground strap issue and was sent on my way. After investigating, there is a gm service bulletin (#23-na-201) on the issue but does not cover my truck. After a week of vacation, began driving truck again and alarms became more frequent, including loss of power steering and jerking of steering wheel while driving. Arranged with dealership to replace the ground strap (at my expense). By the time they could schedule, the alarms were constant and the truck had completely lost power steering. One of the power steering failures nearly resulted in an accident while turning.

I was camping at a state park outside of kenton ohio. On Sunday July 19 2026 while backing up my travel trailer I lost power steering to my 2019 Silverado 1500. Then a message came on my display saying service power steering soon and then a check wiring harness warning. I turned off truck and restarted it and warnings cleared and power steering came back. The following morning July 20th started the truck, no power steering and service engine light was on drove to kenton and had codes read. Had multiple codes for different control modules. Power steering came back and I was able to drive home. Called my dealer and was able to get appointment on July 24. Tried to start truck and it would crank, start run rough for a few seconds then stall out. Had to have it towed to dealer for repair. End result faulty ground strap from body to frame, loss of electric power steering ability while driving due to a ground cable could have been a very dangerous situation for everyone in the vehicle and on the road.

Tailgate keeps randomly opening when driving down the road. Vehicle was taken to a Chevrolet dealership for them to address. Gm denied warranty claim and will not provide anything in writing. This is a huge safety concern for a work truck that hauls tools and equipment on a daily basis. And the fact that gm will not give anything in writing on the denial is absolute bs.

Approximately one week ago I was driving at a safe speed on a two-lane highway. Suddenly, my steering wheel and truck jerked to the right. For 8-10 seconds a warning message was displayed "power steering . . . Drive carefully. " I took the truck to my local dealership. They scanned for trouble codes. The technician said something about an interruption communicating with the electrical system. My service advisor took the truck on a 15-mile drive and had no problem. They scanned again and there were no trouble codes. The service advisor said they could not fix the problem if they did not know the cause of the problem. I left the dealership. Since then, I have had 4 more incidents. Once the warning message appeared again, but no jerk of the steering wheel or truck; once there was the same warning message and a jerk of the steering wheel and truck; and twice there were sudden jerks of the steering wheel and truck but no warning message. I have reported each of these incidents to the dealership. I also called Chevrolet customer assistance. I explained the problem and asked if they would assign a field service engineer to assist the dealership. Hey declined my request. Because I momentarily lose control of steering the truck, I fear for my safety and the safety of others.

I have been having issues with my vehicle for the last 1,000 miles or so where it appears to be losing power while accelerating normally, I'm not sure if the issue lies with the engine or powertrain/transmission. I took to dealer last week and they were unable to reproduce. The issues have been getting more frequent and intially were only occuring after the vehicle warmed up, now it has started while vehicle is cold. Feels like the power drops (rpms drop) during a normal acceleration. As of 7/16 I now have a check engine light on, onstar indicates an issue with my engine, transmission, electrical. This is putting myself at safety risk along with others as during my normal drive the engine is losing power and could either leave me stranded or cause an accident.

Check engine light repeatedly comes on. Take it in, multiple chevy dealerships “fix” the errors such as fuel line pump 5x, gear shift issues, modules that went bad and various other issues. I routinely take care of vehicle (oil changes, tire rotations and service when needed) this truck will randomly shut off while driving (stop and go traffic ) I was told to turn off the start/stop which I do every time I get in the truck. However it recently wouldn’t turn over after going through a car wash, it would try and try till I manually stopped it. It’s running rough now and I pray everyday the check engine light doesn’t come on or that it doesn't just shut off mid drive. This truck has been hell on wheels and I bought it with 10 miles on it. Bought it from autonation in 12/2023.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that the vehicle failed to start. The vehicle was towed to the residence and jump-started. The vehicle was then driven to a dealer, where it was diagnosed and determined that the grounding straps were damaged, and one strap was severely corroded and fractured, while the other strap was severely corroded. The dealer determined that the grounding straps needed to be replaced. The vehicle was repaired at the owner's expense. Upon investigation, the contact associated the failure with gm customer satisfaction program: n252515590. The manufacturer was notified of the failure and informed the contact that the cost of the repair could be reduced at the discretion of the dealer. The failure mileage was approximately 135,000.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that a body-to-chassis grounding strap was previously replaced under gm customer satisfaction program: n252515590 (corroded ground strap); however, after the repair, the vehicle experienced electrical failures. The contact stated that while attempting to start the vehicle, several unknown warning lights illuminated, and the engine failed to start. The vehicle was towed to the dealer, where the starter and the ecm were replaced. Additionally, the dealer determined that a secondary grounding strap needed to be replaced, but the part was not covered under the customer satisfaction program. The manufacturer was contacted and referred the contact to the NHTSA hotline for assistance. The vehicle was not repaired again. The failure mileage was approximately 100,000.

On Thursday, July 9, 2026, at approximately 2:30 p. M. , I was driving my 2025 Chevrolet Silverado 1500 duramax on highway 40 while towing a properly connected trailer. The multi-flex tailgate had been fully closed and latched before I began my trip and had not been opened at any point prior to the incident. While traveling on the highway, a California highway patrol officer pulled alongside my vehicle and alerted me that my tailgate was down and bouncing on the trailer I was towing. I immediately pulled over to the shoulder and observed that the entire multi-flex tailgate had unexpectedly unlatched and was resting on the trailer. I closed and latched the tailgate, which appeared to operate normally, and continued to my destination. At no time before or during the incident did the vehicle display a "tailgate open" warning or any other warning message on the instrument cluster. The unexpected opening of the tailgate caused it to strike the trailer, resulting in damage to the multi-flex tailgate, the rear bumper, and the trailer. The vehicle has approximately 11,000 miles, was purchased new, and has not been modified. I have opened a case with general motors, and the vehicle is scheduled to be inspected by an authorized Chevrolet dealership.

Vehicle suffered a failure cascade of the brake booster vacuum pump system. During a low-speed bumper collision on July 4 and a boat ramp slide, the pedal triggered abnormal abs-like pulsing as the computer tried to hydraulically compensate for dropping vacuum pressure. This resulted in truck front bumper damage and boat trailer fender damage. On July 10, total failure occurred in a drive-thru, rendering the pedal rock-hard and sopping mear impossible. All marked parts and logs are available for inspection. Onboard diagnostic data reveals the electronic brake control module has driven continuously without a master clear for 22,665 miles, locking the last system initialization to 78,468 miles. This continuous data loop proves code c0299-00 was actively visible in the history log during the subsequent dealer service visits. Instead of performing the hardware pump remedy under recall n192268490 (NHTSA 19v650). At the Jan 24 dealer visit (78,482 mi), dealer applied a software update and charged out-of-pocket fees to clear symptoms. They also ignored subsequent communication regarding the billing discrepancy. Technicians completely neglected the history logs despite explicit complaints regarding low-speed abs sensations, trailer brake messages, park assist, and brake assist warnings. The 2026 dealers (and 2024) falsified multipoint inspections stating brakes required no service until after winter. Jan '26 dealer delayed further diagnostics until June '26. May '26 dealer ignored texts regarding a crooked steering wheel and unstable tracking after alignment service. The truck was intentionally misdiagnosed as functional to avoid the warranty period repair. This unaddressed mechanical failure caused a destructive system cascade requiring replacement of the vacuum pump, oil-contaminated vacuum lines lines, oil-saturated booster, master cylinder, glazed pads, warped rotors, fluid flush, tires from module drag, alongside the resulting bumper and trailer property damage.

I have a trial boss and it wont shut off when the key is off, keeps running. Did some research and it gave a couple of thing to check.

Vehicle experienced sudden power steering failure and needed to be towed. A list of preceding error codes presented upon diagnostic review including power steering motor circuit, control module power circuit low input/low voltage, steering failure mitigation, power steering malfunction, lost communication with power steering control module to name a few. Dealership traced it back to a known gm part issue with the body to chassis ground strap identified in gm consumer satisfaction program n252515590 in chevy and GMC 1500 2019-2024 models. The identified strap corrodes causing electronic failure noted above and documented by the dealership. The csp was issued in January 2027 and is in effect until February 2028 however the dealership charged my out of pocket $384. 48 for labor for a $13. 40 part. My gm platinum protection plan also refused to cover the cost of the know defective repair.

A valve on the 3. 0l duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for gm and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that gm knows is their fault.

Purchased used 6/12/2026 at 188,882 miles from a franchised Chevrolet dealer. The integrated trailer brake system master fuse and passenger-side turn signal fuse were blown at delivery. When the fuses were replaced, the trailer brake system faulted and the failure disabled the abs, traction control, and stabilitrak (electronic stability control). Significant safety concern: with the master fuse blown/open, the vehicle displays no warning messages of any kind — the safety-system failure is completely masked while trailer braking is inoperative. The warning cascade only appears when a good fuse is installed and the faulted circuit is energized. Separately, at approximately 12 days and ~1,700 miles after purchase, the engine began knocking and set diagnostic trouble codes; a dealer repair order dated 7/6/2026 documents the knocking complaint with no work performed. The vehicle is currently parked as unsafe to drive. No crash, injury, or fire. Reporting so the abs/esc failure mode — and particularly its masking behavior when the fuse is open — is on record for this VIN and vehicle line.

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.

The electronic parking brake system on my 2020 chevy Silverado 1500 continuously malfunctions. Chevy/ gm customer support has been made aware of this issue and continues to disregard it entirely. The electronic parking brake, which is an automatic function that cannot be turned off or bypassed, fails to fully disengage when the vehicle is taken out of park. The electronic parking brake remains very slightly engaged, producing a slight noise while driving and causing excessively premature wear on the vehicles pads and rotors. My vehicle has about 64,000 miles on it, and I have had to replace my rear brakes twice now already, due to this issue. The majority of those 64,000 miles are from uninterrupted highway driving. Each time the rear brakes were replaced, I had the dealership inspect the braking system. The dealership was not able to definitively confirm for some reason but was able to speculate that the aforementioned is likely what is going on. I find that any malfunction of such a critical part of the vehicle and the safety of it's operators and passengers poses a major safety risk.

Check engine light flashes when pulling a load and accelerating above 50mph. Check engine light code is po300 random multiple misfires. Took it to the shop and there we’re currently no active misfires.

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.

The wiring harness failed causing erratic and unpredictable behavior at 65 mph on this 2020 Chevrolet Silverado 1500 with 77,500 miles on the odometer. General motors no longer makes the wiring harness and there are none available in the market. This otherwise flawless truck (for which I paid $40,000 at a reseller in 2024) is essentially now totaled (undrivable) and gm will not take any responsibility or provide any other remedy beside $750 toward the purchase of a brand new truck.

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.
