Electrical System Problems of Chevrolet Silverado 3500 - part 1

1st incident: when driving the vehicle dashboard shut off, no indicators working such as speedometer, gauges etc and brakes were not working, luckily I was in a 60 miles an hour zone so I had to just let the vehicle come to a gravity stop. To turn off the engine and start it back up again. 2nd incident: when driving the dash lights turned off and on like flickering on and off and all the gauges mentioned above did not work, and brakes did not work. This is very scary! all power in the truck is lost while driving and braking issue!.

I have been experiencing the "shift to park" issue that gm vehicles have been experiencing. My 2320 Chevrolet Silverado 3500hd high country is not on the recall for this issue, and I have approached my local dealer about it. I have not been able to fully addressed that issue yet, because I am dealing with a failed transmission valve body that is covered under my drivetrain warranty, but not the gm recall for the 10l100 allison transmissions (gm n242454441). I undoubly have faulty parts/components contributing to this issue the fails to completely allow my truck to shift to park and allow me to completely turn the truck off and leave the vehicle.

The tailgate is unlatching itself (electronically). This occurs every 30 seconds when the vehicle is parked. This is a safety issue because if someone is standing or walking behind the vehicle, the tailgate will open and injure them. Because the lights activate when the tailgate unlatches, the battery was drained and the vehicle could not start. Thus damaging the life of the battery. This has occurred consistently for the last 2 days. The dealer has the part for the issue because the 2024 has a recall but 2025 (ours) does not. Please be advised, the drained and dead battery had left us stranded.

Electrical components are failing in the tailgate lock/unlock mechanism. The tailgate goes up and down on its own while in park. It will also go up and down on its own after the truck is off and unattended this started happening about a week ago. It is available for inspection upon request and has not been inspected by any agency yet. The tailgate could damage itself or other property randomly. It could also impact someone standing near it causing injury. There is a service appointment scheduled 3 days from now. There were no symptoms or warnings of a problem. The chevy app actually says that all systems are ok.

After replacement of the trailer brake controller for the well known issue of the new oem trailer brake controller disconnecting from the trailer brakes, the issue still persists. The trailer brake controller should remain connected to the trailer brakes at all times instead of disconnecting under its own control and programming. It is a major safety issue to be trailering a 21,000lb trailer with 6 functional disk brakes and have the controller decide to disconnect at seemingly random times to include descending a mountain pass at highway speeds.

While traveling with a 5th wheel camper (grand design), that has solar panels the brake controller stops providing a connection to the trailer brakes. This is a know problem of the 2024 Chevrolets and so far there is not a fix that I know of. This is a big big safety issue because the trailer is heavy and hard to stop. The documentation from Chevrolet states the issue is once the battery charges and has a higher voltage than the truck battery it will surge the system and deactivate the braking system on the camper. This also hold true when the camper battery is too low, again the truck battery will surge the system and deactivate the braking system on the camper.

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated that while operating the vehicle, no audible sound was coming from the infotainment center. During the failure, the audible turn signal was inoperable and the warning messages from the infotainment center could not be heard. The contact stated that the onstar service would not connect and was inoperable. The vehicle was taken back the dealer to be reprogrammed several times, but the failure persisted. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 100.

Driving home from work 7/1/2024 approx 5:15pm smelled burning smell, no noise or dash lights, thought it was another car. 1 minute later, heard a thump from under hood and "charging system failure" came on dash. Decided to take to chevy dealer, which was 5 minutes away. Within next 2 minutes steering failed. As I came to next intersection, brakes failed, went thorough red light, luckily not hit by another vehicle. Coasted to stop and called tow service. Engine was still running until I turned it off. Had towed to local chevy dealer. Ac compressor had locked up, broken belt. Steering and brakes failed. Dealer agreed both failed, but would not list the brake failure on the invoice. I was originally invoiced 2900. 00 to repair, even though truck had only 29244 miles. That was reduced to 1160. 00. Was told it was 2 months past 36 month warranty. Engine was still under warranty, but ac, alternator, power steering and brakes, was not,. I had contacted gm which originally told me they would reimburse me for repairs and would mail me a check, I have the email. When check did not arrive after 2 months, I contacted my case worker again via email and phone. Could not get a response after about 6 attempts. When I called and finally got another person, I was informed they had changed their mind.

The onstart module stopped working, no internet or gps conection is working, also the emergency call system is disabled, onstart systems is disabled due the telematic control module fault. .

Vehicle regularly stalls while driving, going down hills and any random time at highway speeds, while in traffic, while stopped at traffic controls. This problem happens repeatedly and is apparently related to the “pump mounted driver”, which is prone to failure due to inadequate design for the use and environment. It creates random failures of the pump to deliver fuel.

Service trailer brake system appears and my trailer brake information doesn’t show up on the dashboard when I try to manually engage the electric trailer brakes.

Without warning tailgate will drop without being actuated, even while driving. Things could fall out of the truck box into traffic following me. The tailgate came down while in my garage overnight and the garage door was opened in the morning with electronic opener causing the tailgate to be scratched up as well! dealer has said this has become a reoccurring problem with my vehicle model. Gm apparently has no service bulletin or recall notice for this problem. I called Chevrolet and they have annotated my issue.

Message will appear that states : trailer brake system needs serviced “ when that appears and I am currently towing a trailer I lose all power to trailer including the brakes. I can’t signal I can’t use the trailer brakes. I’m towing 14,000 lbs and when I’m going down a 6% grade this is very dangerous. I have had vehicle in twice for this issue , first time I was told they replaced a controller, 2nd time they said no problems detected. For me to lose all power to tow vehicle is unacceptable and extremely dangerous.

There is an electrical / turn signal and trailering issue. Not towing- the right turn signal gives a rapid flash when the automatic headlights are activated or in off position. The rapid flash goes away when manual headlights are used both running lights and on. Although the light still works with a rapid blink, there is a dash error message and it’s impossible to know while driving if the error is real or not. This issue is intermittent when auto headlights are selected. Towing- bigger safety issue. The trailer lights only work properly when headlights are in auto mode and daylight. When it gets dark, the headlights turn on and error messages happen and trailer lights go out. There are also error messages when manual running lights or manual lights are activated. Thus it appears there is no way to tow an RV safely at night. This did not occur on my 2021 chevy 3500. These issues are wide spread but gm is doing nothing about it. Please help me, the other owners, and the public from these dangerous vehicles.

I believe my def heater has stopped working and my full def tank is now frozen. I’m now stranded in the middle of south dakota in -29 degree weather. My truck will not drive. Or idle for the heater to keep me warm because the def is required for engine to run.

As I am driving I am routinely warned about the trailer brake system with or without a trailer hooked up. It is distracting and could cause potential danger while driving. It has been going on for some time and progressively getting worse.

Recently purchased a 2024 Chevrolet silverado hd3500 and use it to haul a 40' 5th wheel toyhauler. Several instances when I connected the RV electrical cord to the truck I would see a "check trailer wiring" message. Along with this message I noticed there was no current going to the RV brakes. I had several technicians look into matter, but could not find a resolution. Later my brother sent me a youtube related to this problem. It appears that if the RV has solar cells for power or the RV generator is running, the voltage on the RV battery is affecting the truck sensors and disables the brakes. This can be a life threatening issue for the vehicle driver or others on the highway.

The truck started shifting hard. Had it towed home. Then towed to dealership. They diagnosed it with a faulty tcm #24256861. Then said it could be up to 18 months for the part. This is unacceptable in our opinion. Additional expenses, time missed from work, etc.

Automatic tailgate open by itself while vehicle was traveling at 65mph on i64 in virginia between charlottesville and waynesboro. And when we stopped the tailgate reclosed by itself. But we lost our load in bed of truck. State police was called but no report was made because load did not cause accident. The driver heard a warning sound and display said tailgate open while vehicle was moving at 65 mph.

The blower motor for the hvac system caught fire.

We have a 2022 grand design imagine 22mle and when we tow it with the truck we are getting the intermittent message on the dash that the trailer brake wiring is not connected. It continually connects and disconnects as we tow and press the brakes on the truck. We previously towed the camper with a 2011 silverado 1500 and did not have this happen. We took the truck back to the dealer for a service check and they had no answered for us. This is a serious safety concern while we are towing an extra 6,000 pounds behind us.

The electrical connector vibrated loose at the injector. The mechanic said he has seen this happen before and gm said its because those motors vibrate excessively. It caused my vehicle to run in reduced power mode. In that mode it was lurching forward uncontrollably and it felt like the transmission was banging. What damage will that alone cause in the future? also, if gm knows there is an issue, why isn't it fixed? why is the consumer responsible for poor engineering or design flaws? it isn't normal wear and tear or neglect on my part. The repairs including the part and the rental car cost me $640. 45! oddly enough it wasn't covered under any extended warranty or recall so I had to pay out of pocket. Very dangerous and expensive!.

The contact owns a 2024 Chevrolet Silverado 3500. The contact stated while driving 30 mph towing a trailer and depressing the brake pedal, the trailer failed to slow down as intended. The contact was able to continue driving to the destination. The vehicle was taken to the dealer and the contact was informed that an undisclosed electrical module needed to be added to the vehicle. The vehicle was not repaired. The manufacturer was contacted but no assistance was provided. The failure mileage was 2,800.

General motors produces several years of vehicles with a faulty transmission control module (tcm). From 2008 thru 2015, Chevrolet and GMC 2,500 & 3,500 trucks with the 6. 6 l duramax engine and allison 1,000 transmission all used the same tcm; part number 24256861. This part has experienced a very high failure rate. During the summer of 2022, the stock of replacement parts was exhausted and gm seems to be postponing the manufacture or new parts. An estimated 5,000 vehicles are currently unusable due to the failure of this part and no new parts available.

There are several problems I’ve noticed some I fix myself! first of all, I was driving my truck at night on the country road and all of a sudden it starts losing power shut down on me on a little road with no pull over spots in kentucky and just dies completely. My service charging system light came on. I worked on this forever. I noticed it. All of my grounds were completely nasty and pretty much not making contact. I fix the ones that I can find only two I know there’s more, I’ve changed the generator three times and the battery once, the problem happened again and again and again the only way I can stop my truck from dying is when that light come on if I got out and I took the negative wire off of my battery and then put it back on it would run again for about another three days and then if I didn’t see it, I’m stranded very dangerous. Finally I took it to my mechanic up the road and he basically did the same things. I did something about a door switch also though not another battery another generator and he added new battery cables so far it hasn’t done it again. Now my truck when starting to slow down, it will vibrate and shake you to death. You hit a little vibration in the road say a rumble strip. This thing will shake you through the roof in about make you run into another vehicle , also, it’s hard to fill up the gas if you have to turn the gas nozzle almost straight up and down if you’re low on gas to make it except it or you’ll be sitting there for 30 minutes putting gas in your truck. I noticed also all of my wheels are having rough spots on them everywhere and they are rusting into . Another thing that happens this truck eats breaks for breakfast. I have put in the past two years at least have the change the brakes, calipers rotors and all twice a year sometimes three times a year. Also, the trailer brake system light comes on nonstop along with a service stability track on when happen. No wasey no cruise control. I am a masterelect. Maintain truck it ju.

I purchased a certified pre-owned 2020 chevy Silverado 3500hd (6. 6 gas) November 2021. Within the next few weeks, I noticed brake squeaking that kept getting worse and the truck braking system would not stop like the 2500 I had traded in when I purchased the 3500hd. I had to adjust the trailer brake gain control up to as high as 9 or 9. 5, should not have to adjust that high. I had trouble stopping at intersections and quick /emergency braking situations while pulling our trailer. This tells me the truck braking system is not working properly. Prior to leaving on a trip, I was having squeaking noise from the brakes that got louder and louder and more frequent. The dealer (champion Chevrolet) checked the truck and brakes and told me it had the wrong brake pads and had replaced them. The first time I pulled off the interstate on my trip to florida, the brakes began to squeak as they did before. This happened during the entire trip. Over the next few weeks after returning from my trip I had a couple of close calls trying to stop at traffic signals. My breaks would not stop me and I went into the intersection barely missing other vehicles. I am almost to the point of parking the truck until the dealer can make repairs that will fix the issues, but we use the truck to pull a trailer that is a major part on our income. I’ve had the truck back to the dealership I purchased the truck from and they keep saying it is a brake pad issue. They have changed the pads twice so far (I think), and within days the squeaking and noise starts again. Periodically I keep getting a message (service trailer brake system) on my dash display that is difficult to get the warning to stop displaying. The trailer brakes had been checked several times and I have hooked other trucks to the trailer and it works fine. So, the issue is with my truck and the braking system. Jeff moore.

During snow removal the night of December 10, 2021 into the morning of December 11, 2021, vehicle was in reverse traveling approximately 10-20 mph (actual speed at impact is unknown). Upon impact with a tree in the rear of the truck, the airbag system in the vehicle was engaged. The seatbelts locked up, and the airbag chemicals in the steering wheel and front passenger airbag compartment were activated, however, none of the airbags physically deployed. Attached phots will show the source of impact. The frame is likely twisted. Additional photos attached show that the seat belts locked up and that the airbag system was engaged without deployment of bags.

Driving my truck, without a trailer, the "service trailer brakes soon" fault came on my truck. This is a known problem that gm is aware of with their itbc system for years & have done selective recalls for. This a hazard to the motoring public. There is no warning when this fault happens while pulling a trailer & when it does pop up, you lose all trailer brakes. I had the same problem with my 2010 silverado, after numerous visits to the dealership & thousands of dollars & filed complaints with gm & NHTSA, nothing was done. When taken to the dealership, if the fault isn't on the screen, they claim they can't find or fix the problem. I pull a 10,000 pound 5th wheel, I need trailer brakes when I apply them.

Was driving my 3500 (an 8000# truck capable of towing 20k#) and suddenly the vehicle lost power and steering, forcing me to the shoulder of a curvy mountain road, going downhill. Truck then started blinking lights and telling me to restart. Upon restart, the truck would not engage the transmission. Truck was in drive but the motor was just rev'ing. I turned truck off and then back on and it seemed to return to normal. Am not comfortable driving truck at this time. Gm has been notified of the issue, and, has not diagnosed an issue, as of this writing.

Serpentine belt broke . I have it available. Recommended service is 150k miles or 10 years . It broke at 55k and 5 years. Lost brake and steering assist. Almost impossible to stop or turn vehicle. It is a diesel and uses hydraulic assist. Dealer replaced belt could not determine cause of problem. Has not been inspected. No warning.
