Electrical System Problems of Chevrolet Silverado 1500 - part 2

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!!!.

Several times, while driving, the truck will simply shut down. It will becoime difficult to steer, then the engine will stall, killing the rest of the steering and the breaks as well as the dashboard, radio, etc. This can happen at any speed, low speed especially. I will give you an approximate date below, but there have been several incidents. The truck was looked at by our local mechanice, who could not find a problem and by the dealership electrical specialist who has also been unable to locate a problem.

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.

While driving I lost the power steering on the vehicle. I took my truck to a chevy dealership and scheduled an appointment for the following day. I research the problem and found that there was a customer satisfaction program bulletin (n252515590) issued covering this specific issue for my trucks model year but it did not cover my specific VIN. I contacted Chevrolet customer assistance and they told me to file a complaint with NHTSA.

I was at a stop light. Let my foot off brake vehicle revved up and I launched into a vehicle in front of me. Check engine light was on before. Blinking, esc fault , forward collision detection was not working, traction control service light. Throttle body control issue detected code p0205. Valve timing issues detected codes p0353 p0355 p129f p0300. The wire above my shock bolt is completely cut into. Gm did an investigation and said no issues were detected at all. There is a TSB for the wire chafing.

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.

I am reporting a safety concern involving my 2026 Chevrolet Silverado 1500 high country equipped with the 6. 2l v8 engine. I purchased the vehicle new on August 3, 2026. The engine has unexpectedly shut off on two separate occasions while the vehicle was still moving at low speed. The first incident occurred within approximately the first week of ownership, when the truck had less than approximately 1,000 miles on it. I was slowly driving through the parking lot at mcb’s when the engine unexpectedly shut off while the vehicle was still moving. The instrument panel displayed “press brake to start. ” the engine did not automatically restart, and I had to stop the vehicle and manually restart the engine. The second incident occurred on September 18, 2026, while I was slowly driving through a parking garage. Again, the vehicle was still moving when the engine unexpectedly shut off. The instrument panel displayed the same “press brake to start” message. The engine did not automatically restart, and I again had to manually restart the vehicle. I have a video recording of this incident. This vehicle is equipped with automatic engine stop/start. During normal stop/start operation, “auto stop” is indicated on the instrument panel when the system shuts the engine off. During neither of these two incidents did the instrument panel indicate “auto stop. ” instead, the engine unexpectedly shut off while the vehicle was moving, displayed “press brake to start,” and required a manual restart. Both incidents occurred while maneuvering at low speed in parking areas. I am concerned that the same failure could occur at a higher speed, while entering or crossing traffic, or in another situation where an unexpected loss of engine power could cause a collision. The vehicle has also experienced intermittent electrical/electronic issues, including radio interruptions, remote-start problems, a “key not detected” message, memory-seat/seat-recall problems, and an intermittent power running-.

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.

Body to frame ground cables corroded in half two different times within about 6 months. First time engine wouldn’t start had to have it towed to dealer for repair, over 30 codes were shown when this happened. Next incident some of my lights were working intermittently and my steering was rendered inoperable for 20 to 30 seconds at a time making it impossible to steer the vehicle, several codes were found when this happened, I drove the truck to a Chevrolet dealer for repair. Both repairs were deemed to be corroded ground cables. Chevrolet has a “customer appreciation program” covering 2019-2024 silverado trucks but for some reason my VIN number doesn’t land in the program even though it has the same issues that are covered for the other silverados.

2021 silverado engine failure. Yes it was inspected by a dealership and my extended warranty company and serviced by the dealership. Back on August 5th I experienced a misfire cylinder 3 and felt loss of power. On August 7th the dealership diagnosed both camshafts, 1 lifter, 1 valve, and 1 fuel injector was damaged and never received at warning lights or messages on the dashboard. I was without the vehicle for 39 days and within 10 hrs after picking up the truck I got an engine light on and several new codes on it and can not be driven and being towed. I feel these engines need a recall as it is well documented that these engines go between 60 and 80,000 miles and some a lot less than that, mine has 70,800 and went and now being towed with in less than 24 hrs after engine repair. I will be in contact with a lawyer to follow up on this matter.

From a stop during fast acceleration made a left turn and rear section or rear axle sounded like it went over a speed bump or wheels locked up, then transmission felt like it was in high gear, did not want to move , or very slowly , I accelerated rpm was 2k or 3k still moving very slowly, this was in heavy traffic. I notice that check engine light went on with tc, parking brake service , some pad lock ( dont know what the ped lock is). 2nd time this happen the parking light service light went on and the brakes locked up again in traffic. 0.

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.
