Electrical System Problems of Chevrolet Silverado 2500 - part 2

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.

Vehicle will crank but will not start. Throws code u0109. Fuel pump control module is on backorder with no estimated time frame. I am not the only person this is happening to with a truck that we are making payments on and will not run.

I bought my track about a year ago. Within the first week of owning it. Multiple times a week, when I start it there is no sound. No radio, music, blinkers, etc. Absolutely no sound. Some of the time once I get to where im going, turn it off. Once I start it again it's back. The other times takes a couple times to hear it again. When I asked the dealership, I was told it's a known issue. 9 months later it still does it. Some weeks once or twice. Other weeks up to 10 times. I pd alot of money for my truck and yes I expect it to have no problems like this.

While driving with a trailer connected the display in the truck will say trailer disconnected. Then the light will go away and come back on. The trailer plug and the trailer are connected and the plug is tight. When this happens the trailer braking system is disabled (trailer has no brakes) I can plug the same trailer to Ford or Dodge with no issues. Have had the chevy to the dealer 4 times now and they are unable to duplicate the problem. I have researched the problem on the internet and there are a lot of discussions of other people having the same issue. GMC has replaced the trailer control module, but this did not fix my problem. I am at the point the dealer and GMC are giving me the run around. I bought this truck for commercial use and frequently haul trailers. It is very unsafe when the brakes on the trailer are disabled.

- electronic power steering assist malfunctioning. Available for inspection - vehicle jerks steering to the left or right at highway speeds, causing near miss accidents. - dealer performed alignment and did not know how to fix. They were able to replicate the issue. - no other inspection - "service power steering drive with care" message intermittently displays and almost immediately goes away. No check engine light or other warning lights.

Tail gate is opening on its own. We checked the recall list and although our year, make and model is listed, the VIN# doesn't show a recall. Clearly, there are more vehicles affected than GMC has included. This is a very serious safety issue and we thought you should be aware that perhaps the recall on the tailgates involve more vehicles than they've included.

“service trailer brake system” warning on dic. Vehicle undriveable, inop, safety issue! start truck, the above warning will flash off and on, code c1117 dtc.

The vehicle mileage is 1,886. The vehicle steering command left or right turns had beautiful chime sound. The dealership could not find the signal chime commands. They claim that this vehicle doesn't have chime when turning right or left. This high-end truck has a lot features that dealership don't know about. This vehicle mileage is very good on the highway 22. 4 miles per gallon.

The vehcile only has 1779 miles. The ac unit operated for short period time. The outside temperture was 95 degree fahrenheit all the controls were not inoperate. The a/c compressor pump was not functioning. The only items working was the fan motor blowing hot air. I restated the vehicle and still no cold air output. The dealership said they could not find any problems with a/c unit. The unit operated normaly and the tempertuer is 35 degrees output. The second problem the dash panel emergency light cable was never installed. The dealer had to order the part.

Electronic trailer brake controller when using disconnects and reconnects turning trailer brakes on and off creating an unsafe situation by never knowing if trailer brakes are going work. Dealer states no problem found with controller and changed trailer plug. Not correcting issue. Tried 2 other trailers same issue occurred. Leading to believe controller is issue. Web search indicates there are many others with similar issue. Dealer states there are no recalls indicating this issue. This has been issue for a few weeks while traveling with a travel trailer.

The tailgate opens on it's own. This is unsafe because the tailgate can open without me knowing it and cause a safety hazard by hitting someone or by items falling out of the bed of the truck while driving. That can cause injury or damage to people and/or property.

When I park and attempt to turn off my truck, the key will not turn completely all the way so I can take it out!!! takes multiple times which is extremely incovenient.

The contact owns a 2015 Chevrolet Silverado 2500. The contact stated that the infotainment system, the audible chime to notify the driver that the door was opened while the key was in the ignition and the seat belt chime reminder were inoperable. The dealer was notified of the failure and informed the contact that the VIN was not included in NHTSA campaign number: 14v301000 (electrical system, seat belts). The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 175,000.

Lost power while driving for 30 seconds. While on the interstate. Now truck battery has to be jumped to start. Dashboard giving out random codes. Check 4x4, check def( def is still at half full), check trailer( no trailer is connected) took to dealership, 4 active codes p0336, p12a6, u029d, u029e. Test failed since code cleared u18d7, u18fe current codes c1596, c15ac.

Solved my u029e with "exhaust fluid service" and "reduced speed". For the past month I have been working on this issue on my 2017 Silverado 2500hd lt 6. 6l. Tonight I purchased my 3rd nox2 (downstream) sensor and immediately everything was fixed. So, what happened? why did the previous 2 nox sensors not work? a clue came from gm parts direct as the original part number was listed as "discontinued". Previously we had purchased 2 numbers matching nox2 sensors 12676706. So why did these sensors not work when the one see image below immediately worked? chevy! they programmed out part number 12676706 from the computer and programmed in 12718676. 12718676 cured our u029e and "exhaust fluid service" and "reduced speed" issues. Companies are still selling nox2 part number 12676706 because it was the original device do not purchase the discontinued nox2 sensor 12676706. Instead purchase the 12718676 part number.

Tailgate automatically opens and closes on its own.

Keep getting message service trailer brake system. Over and over going down the road,.

Another day another code. P11db (nox upstream). Now I am at nox downstream, nox upstream, def pump, cylinder 7 wire connector, trailer brake controller wire harness, temperature sensor, and a dozen chafing wire harnesses because they are pulled to tight, have extreme bends in them or are rubbing against the frame, bumper, etc. Chevy recommended that I replace the cylinder 7 injector which was not the issue. At this rate if I paid chevy to diagnose and repair this vehicle I would easily be $5,000+ in repairs since chevy wants to do cab-off maintenance on everything now. This is manufacturer defects and consumer fraud and nthsa is not holding chevy accountable for. My dad has a 1978 pinto that he can start up and run to town but my 2017 silverado can't even leave the farm.

This is my 3rd complaint within 6 days. The entire electrical system in this 2017 Silverado 2500hd lt 6. 6l appears to be committing suicide. First it was the brake controller unit, diesel injector connector (cylinder 7), p1050 def level sensor, u029e nox sensor module 2 communication lost, u02a3 lost communication with particulate matter sensor module, and now p018b code: fuel pressure sensor "b". At what point will the manufacturer be held accountable for manufacturer defects on this vehicle (including the dorman 603-009 coolant reservoir)? every pump and sensor on the truck is failing within a week of the trailer brake controller failure? why is every wire harness on this vehicle (like so many others) failing? I cannot trust that I can even drive this vehicle without either stabilitrac shutting it down or the defective wire harnesses catching fire.

Engine wiring harness failure on my 2017 Silverado 2500hd lt 6. 6. This time it is the cylinder 7 connector which is a very common complaint by chevy owners. The wiring harness was installed with wires that were to short for the rear cylinders causing them to fail prematurely. This connector is snapped into position forcing the wires to bend at a tight 90 degree angle. Chevy is trying to force owners to replace the entire wiring harness instead of replacing just the defective connectors (gm 19368140, acd pt3739). This failure causes the engine to idle and operate so rough that it engages stabilitrac and forces reduced power mode.

Tailgate opening and closing on its own. No input from key fob, switch on tailgate, or switch inside of cab. No fuse indicated to pull to stop.

The contact owns a 2019 Chevrolet Silverado 2500. The contact stated that the main information center changed the information displayed, such as tire pressure. The back-over prevention camera was no longer displayed when the radio was in use. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The manufacturer referred the contact to the NHTSA hotline to report the failure. The failure mileage was 120,000.

Charging system failed the system failed with no warning, we were traveling on a country curvy road and about to descend a grade. With the charging system failure, the truck lost power to brakes and steering. It's at the dealer, being inspected etc. No warning lights or message until the failure occured, then a battery light appeared and a charging system failed message.

When pulling trailers I frequently get warning to check trailer wiring. I have gotten this warning with every trailer I have towed to include, my travel trailer(camper), livestock trailer, car hauler trailer and enclosed cargo trailer. It is intermittent but frequent. I am unsure if trailer brakes will engage during this failure.
