Electrical System Problems of Chevrolet Silverado 2500 - part 2

When vehicle is placed in park the safety lock will not allow the key to turn to the "off" position and be removed. The vehicle will not turn "off" any further than the accessory position. Sometimes after turning the steering wheel back and forth while working the ignition the key will release. If this does not work after a minute or so, sometimes you can start the truck and immediately turn it all the way off and get the key to release. If all of that fails the last option is to disconnect the battery. It is an intermittent issue that will happen 5 times a day for a week, and then will not replicate again for a week or two.

Tail gate opens and shut by its self while I’m going down the road have dropped a couple things out and lost them could have been worse if some one hit by jack that fell out.

The tailgate would open and close on its own. I was about ready to connect my fifth wheel RV for a trip when suddenly as I closed the truck door to back up I saw that the tailgate had opened. I proceeded to put it in park and the tailgate closed on its own. Got out as leaving the door to the pickup I walked to the rear of the truck to notice the tailgate open and close on its own. I am expecting this issue to be recalled for a repair as I have read that 2024 has this same issue and that they will be recalling trucks from 2020-2024. The issue is due to a faulty relay when wet. This vehicle is equipped with power-unlatching tailgate. I believe if this issue would have went unnoticed and continued to hook up my fifth wheel the damage would have been horrific. Thanking you in advance, sincerely, james.

While pulling my vilano fifth wheel trailer to alabama from my home state of texas the driver information center alerted me that the trailer brakes were disconnected. Then a short while later it alerted that trailer brakes were connected. This situation continued for the entire trip to alabama. When the info center indicated trailer brakes were disconnected, they were indeed not working. Several times I almost rear ended cars stopping in front of me. (the vehicle had a recall notice urging to take it in and replace the brake module shortly after purchasing it. I did this. ) once I arrived in alabama I took the vehicle to the Chevrolet dealership in foley, alabama to check the braking system. They told me there was no problem with the braking system. I retrurned to my home in little elm, texas with the problem occurring the entire trip. I finally made it home and today took the vehicle to james wood Chevrolet in denton, texas to have the braking systme checked again. They told me there was nothing wrong with the braking system. The service writer did say that because the trailer has led lights the braking system does not recognize the voltage from the trailer and that is why the brakes are disconnecting. Please help me find out how to correct this extremely dangerous condition while I am towing my 16,000 pound fifth wheel trailer.

Very limited while driving in the dark cause head lights go off and can’t drive in the rain or snow cause wipers turn off not save for my family and I and other drivers on the road thai all happen, after the dealer (lithia Chevrolet of redding, CA) performed gm recall programming on the serial data gateway module (sdgm) and related software updates, my truck began having serious electrical failures. Immediately after the recall work, all exterior lights, interior lights, and trailer lights began flickering on and off while driving. The windshield wipers also pause or stop for a moment when this happens. None of these issues existed before the recall. This appears to be a module reset or corrupted calibration caused during the recall reprogramming. Gm has already told NHTSA that they have hundreds of field complaints about flickering headlamps on 2024 trucks, and they identified lighting flicker as a safety defect. My symptoms match those issues exactly. The dealer refuses to accept responsibility, saying the recall is “closed,” but the electrical failure only began immediately after their programming. This is a safety hazard when driving at night or in the rain, and it affects the trailer braking/lighting circuits as well. I have an active gm case opened for this issue. The truck is unsafe to operate in this condition. I am requesting that NHTSA investigate whether the recall programming is causing electrical module failures and whether additional action is needed.

Power tailgate opening unexpectedly. Tailgate opens and closes without warning. The same issue that safety recall n232426400 describes.

The vehicle's tcm has apparently failed as evidenced by cel code "u0101", low power ("limp mode"), hard shifting, no gear selection indicator, and extremely slow acceleration. Vehicle is currently available for inspection, but will be receiving a replacement tcm soon. Myself and others' safety was put at risk due to my the vehicle's inability to continue through an intersection at a reasonable rate. The problem has not been reproduced by a dealer/service center, nor has it been inspected by anyone since the incident. The aforementioned warning lamp that indicated the issue appeared upon starting the vehicle, which drove normally for the first 11 miles.

After driving truck. Attempt to turn keyed ignition off, they key will not move the the off position for removal. Must wait several minutes for the key lock mechanism to release then remove the key.

The tailgate on our truck keeps automatically coming down and up on its own. It doesn’t matter if the truck is in park or drive. It doesn’t matter if it’s locked or unlocked. It will do it several times in a row. It will go half way back up and then just slam down. Unfortunately we didn’t know this was an issue as we just bought the truck a few days before we noticed it happening and it fell down and hit something in our garage causing a dent and multiple scratches as it happened overnight without us being aware of the issue. It happens when I’m going down the road, which means I cannot use the bed of my truck as things could fall out. Also, I’m limited on where I can park it. We called gm and a dealership and there’s nothing they can do since it’s not recalled unless we pay to have it fixed. So now we have a new to us truck that’s now dented because of this issue. There is no warning it’s going to happen. After the tailgate comes down I get a notification saying tailgate down when I’m driving. This happens everyday, several times a day and we’re having to avoid driving it when possible due to this issue.

Intermittent loss of trailer brakes. Trailer has small break away battery.

I was driving my truck and lost full power to the truck. Which happened as I was pulling out of a parking. The truck went into a limp mode. With the truck losing full power, it put my child and I into a safety risk. The truck got repaired at the dealership. The dealer was able to reproduce the issue. The truck was inspected at the dealership. Warning system did come on saying speed would be limited if (roughly 150 miles to a max 65mph). When I called another dealership, they said this was a normal thing for these trucks and chevy hasn't fixed it. I feel like if its a known issue with the wiring becoming free, why would they not proactively fix this issue before someone gets hurts from thinking they have the power to drive. The dealership that I took this too knew where to look right away as this is common.

Intermittent lose of trailer brakes.

My trailer brake controller routinely does not allow me to adjust the brake gain. Multiple times (and on recorded video), I’ve had instances where I could not increase gain while hauling heavy loads in the trailer and this has caused me to lose my ability to stop the vehicle effectively. This has nearly cause accidents a few times while hauling on the interstate, and down my mountain road. The driver must be able to adjust trailer gain at any point while operating the vehicle. This issue has happened with multiple trailers. I’ve taken the vehicle in multiple times and had the brake controller components replaced but this issue still exists and the dealerships are unable to resolve. I was informed I have trailer issues even though this only occurs in this vehicle while towing and not other vehicles pulling the trailers. This is a major safety issue and will cause an accident if it isn’t resolved. My only option at this point is to purchase an aftermarket brake controller as my factory brake controller is unsafe. I have multiple videos of this issue and nearly had the trailer push me over my mountain from the issue. This issue has happened since I purchased the vehicle and continues to happen. There are multiple service records which show I requested the brake controller to be fixed. This isn’t a one time date or speed. I’m unable to upload videos I’ve taken on my phone but I can send them in. Reach out to nickrone99@gmail. Com for videos. The manufacturer and service centers aren’t helping resolve this.

Intermittent lose of trailer brakes. Dealerships are unable to duplicate issue, will not replace under factory warranty. Chevy has not issued a recall for this specific VIN. But other 2024 chevy 2500 have had recalls for it. Would like a recall for my VIN die to this being an issue if an accident occurs. Traveling with multiple 10k pound trailers and no brakes.

Intermittent lose of trailer brakes. Dealer failed to diagnose and fix issues. Stayed if they can not replicate it, they will not warranty it.

Intermittent lose of trailer brakes.

Steering great box replaced steering still not stable, electrical glitches such as stability trac service message, hill assist, breaking assist messages pop up and then disappear constantly, power steering pump, hydro boost and master cylinder replaced multiple times, no sound emitting for seat belt, door chime , turn signals with no accessory mode power when key is turned. Vehicle has been in and out of shop for repairs and noone can figure out the sound or electrical issues and keep replacing the steering and power steering components. When using driver side window switch all dashboard lights increase in brightness then dim back down.

Trailer brake control module in vehicle will have intermittent loss of trailer brakes. Dealership stated they will not fix the issue if they are unable to replicate it. Even with video or picture evidence. Dealership has been uncooperative during the process.

Vehicle’s braking system for the trailer constantly disconnects while driving. The trailer will then lose all braking capabilities. Multiple service trailer brake system, check trailer wiring harness, trailer brake connected messages. Issues started shortly after purchasing the truck new at only 55 miles on the odometer.

Receiving service trailer brake system. Seems this is a known issue with truck and should be a recall that gm fix and not put onto customer.

Have had issues since purchase of paint chipping severely / cloudy. Transmission shudder and “jumped forward” when coming to a stop. Lighting system “blinked” or went dark and come back up a few seconds later while driving.

Day after driving to n a snow storm the vehicles stabilitrak and traction control light and message to service those came on the dash and a sudden lose of power. I pulled over and put it in park noticing the gear indicator on the dash was gone. I put in drive and could barely move. So I shifted to 1st gear then back to park and into drive and the light came off and it was back to normal. The next day I started the vehicle and the light was on again with the check engine light. And stuck in limp mode. There are forums I've read with thousands of people with the same problem. The vehicle is available for inspection. The safety concerns are the traction control and stabilitrak can affect the way it handles and brakes. The vehicle will be going to dealership. There where no warning light prior to. The lights and systems failed simultaneously. This vehicle only has 44000 miles on it, no rust the frame is mint. This is a very clean truck and shouldn't be having this kind of problem.

In certain GMC and Chevrolet models 2019 to 2025 it is common knowledge and easily found on the web that there is a manufacturer defect that does not allow the vehicle to be placed in “park” properly due to defective parts in the steering column that do not allow the vehicle to safely turn off fully. The module does not seat and the vehicle will remain on in auxiliary. Https://m. Youtube. Com/watch?v=rtcx-j3r5oq . Again the link is an example but this defect is rampant.

The contact owns a 2025 Chevrolet Silverado 2500. The contact stated while her husband was hauling a trailer and driving 55 mph in the snow, the vehicle lost power steering functionality. In addition, the contact stated the vehicle failed to accelerate as intended while depressing the accelerator pedal before slamming into gear. The rpm fluctuated up to 6,500 rpm. The contact stated that the check engine warning light was illuminated. The contact's husband was able to coast to the side of the road. The vehicle was turned off but failed to restart. The contact's husband stepped out of the vehicle, and the vehicle restarted automatically. The vehicle was towed to a dealer, where it was diagnosed that the wiring was for a diesel vehicle; however, the contact's vehicle was gasoline operated. The contact was informed that the wiring harness control arm had rubbed against the control arm, causing the electrical system to short-circuit. The vehicle was repaired. The failure had progressively gotten worse. Most recently, the contact stated that the vehicle vibrated abnormally while driving. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that a seal was placed on the transmission. The manufacturer was made aware of the failure but denied assistance. The failure mileage was approximately 42,000.

Rear back-up camera is intermittent and is a safety concern due to the size of the vehicle. I makes it un-safe when backing up. This has been happening more and more. Screen is either black or icon displays that the camera is not working.

"n192265660 - customer satisfaction program rear window defroster thermal events - us only" rear window shattered after having the symptoms described in customer satisfaction program n192265660. Rear defroster would smoke/smell hot when activated. The symptoms were brought to the attention of the dealership prior to window breaking, but nothing was done due to the VIN not being part of the listing. Now I have no rear window and parts are on backorder with no eta. Not to mention this will be out of pocket costs that could have been prevented. This glass shattered all over my [xxx] old daughter. This has also been known to cause fires according to the bulletin. This should be a recall. If it already is a recall my VIN is certainly affected by this problem but is not listed. My VIN should be listed along with several others. This is a relatively common problem. Dealer refuses to work with me on a cost effective solution. No warnings other than the described symptoms that were brought to the dealer as previously stated. Approximate time frame was Dec 2022. Dealer did nothing due to my VIN not being listed as part of this program. Truck was parked in the garage when the window shattered. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Engine code p10d9. Electrical harness to the def tank melted. My truck was not part of the gm recall but clearly effects more vehicles than they believe. See NHTSA report n212342980. Spoke with chevy customer service today and they stated the wiring harness melting is not covered under warranty. This is a fire hazard that gm should remedy. The recall is clearly larger than 38,000 vehicles. Are we supposed to drive the vehicles and not know if they will catch fire or not? I spoke with a technician at milnes chevy in imlay city today and he stated that he sees so many of these trucks that were not under the recall having the same issue with melted wiring harness.

The def heater short circuit and derates the truck. If the government says we have to have this they should cover the cost to fix it.

Vehicle gives "shift to park" warning when already in park. Occasionally, vehicle will not shut off. Once it does shut off, dash lights and controls do not shut off. Vehicle will not lock upon exit. Warning lights and beeping causes battery to drain. I have been left stranded with dead battery twice.

When shifting into park and turning ignition off a message appears on dash saying to “shift to park”. Vehicle will shut off but will not then shift, nor will steering will lock and ignition will not shut off. It is unclear if vehicle is actually in park mode. Vehicle has to be left running for up to several hours before transmission recognizes that it is in park and then ignition will turn off correctly. This issue has been experienced by many Chevrolet owners. Issue has been reported to gm.

So the electrical would be when I shut my truck off in park I cannot turn my key completely back to release the key so therefore I’m killing my battery leaving the power on as far as the tires they’re rated for 50 or 55,000 miles I have 37,000 miles and I have no tread left and as far as my drivetrain when accelerating onto a highway pulling my fifth wheel camper that is 16,000 pounds loaded the truck box really bad as far as the crash warning breaking system it does not break.

While driving I smelled burning electrical somewhere in the cab. Looking in the rearview mirror I saw smoke ciming from the corner of the sliding rear window. I pulled over and opened my rear door and heard a crack type noise. The smoke stopped and the drivers side rear window was shattered. Upon researching the issue I found a recall was done in canada and not in the USA .

The tail gate opens when parked and remote is on the counter. Tail gate now has damage from opening on its own and hitting the garage door. This has happened on multiple occasions and in multiple scenarios.
