2017 Chevrolet Silverado Electrical System Problems

Odometer Fraud. The contact purchased a 2017 Chevrolet Silverado 1500 on January 16, 2026. The contact stated that while an independent mechanic was attempting to repair the engine, it was discovered that there was a mileage discrepancy with the vehicle. The vehicle was a private sale. The contact called the private dealer and requested the money back that was paid to purchase the vehicle, and the dealer declined the request. The contact called the State Attorney General's Office and was referred to the NHTSA Hotline for assistance. At the time of the purchase, the mileage was approximately 182,000; it was later discovered that the correct mileage was 192,393.

Trailer brake warning

The rear window of my 2017 Chevy Silverado exploded. I had the rear defrosters on, and they malfunctioned. I thought I smelled something hot before this happened. I am surprised this didn't cause a fire. I have researched this issue, and it appears to be an ongoing problem with the 2014 - 2019 Silverado and Sierra trucks. In fact, Canada has a recall on this issue, but the U.S. does not. Why is that?

After starting the vehicle. I heard a hissing noise coming from the rear of the cabin. I looked in the rear view mirror and saw a large amount smoke rising from the box where the rear defroster power connects to the window. I immediately shut the vehicle off, got out and walked around the passenger side of the vehicle. As I approached the passenger rear door, the rear passenger window exploded with a Loud pop, shooting glass across the bed of the truck. I know there is currently a recall for this issue in Canada.

Electronic brakes lock up during driving. No power going to rear wheels.

The AFM system is a faulty system that starved my lifters of oil and they ended up collapsing causing a flat spot on my cam. The engine code would come up as a misfire but the code is caused by the flat spot created on the cam by the lifter it's a faulty system that cost me $7,000. My 8spd transmission also has a hard shift from 1st to 2nd pushing the vehicle forward and jerking it when it shifts. The dealer and GM said this was natural with this type of transmissions which we now know is a lie.

Electronics for hands free stopped working. This part was already replaced once. When backing up, the whole truck shut down. I restarted, it said to roll drivers side window down and up. Truck started up again. Few days later... returning from trip, lost power, windshield wipers came on, electronics in truck started blinking. Pulled over, rolled driver's side window up and down. started back on road. This has happened numerous times. Whenever I gave it extra gas, asking for power to pass, same thing mentioned above happened. Very stressful! Next day, hit a hole, truck totally shut down again. Husband was able to safely coast off road, however, if he had been pulling out at a major intersection, this could have been bad. Warning light that comes with shutdown says "stabltrack issue". I have not seen our dealer service department yet, but plan to very soon. VERY unsafe... and I love this truck!!!!

Unknown system or component failure. Vehicle is available upon request to inspect. My families safety was at risk, power steering goes out while driving, all service lights come on, vehicle goes into “limp mode”, would go in and out of gear while driving, gears won’t work properly (P,R,D…), when shifting into R camera won’t come on. This problem is continuing. Have not been able to get it into dealership. Vehicle has not been inspected by police, dealership, or insurance. Stabilitrak notification, and all service lights go off. No problem or symptoms prior to failure. Vehicle was well maintained and I have service records of every repair, oil change, etc.

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated while driving or while the vehicle was parked and occupied, while depress the horn, the horn failed to operate. The contact turned off and restarted the vehicle, but the failure persisted. The contact stated that the failure started in 2023. The vehicle was towed to an independent mechanic and was diagnosed and determined that the horn had failed and needed to be replaced. The contact stated that the failure had occurred on several occasions. The contact stated that the vehicle had been repaired once. The horn was replaced the first time; however, with the current failure the horn was not yet replaced. The manufacturer was not notified of the failure. The approximate failure mileage was 155,000.

At night when in reverse, the dash camera does not dim as the rest of the dash does. The screen is far too bright inside the passenger compartment and you cannot safely maneuver the vehicle. There is no manual adjustments available.

I was parked at a gas pump, just got done fueling, hung hose up. I quickly ran into the gas station to grab a drink and as temps are 0°F, I remote started my vehicle from check out counter. When I returned to my vehicle the cab was filling with smoke. I sprung into action and quickly but safely drove away from gas pump with very little visibility, due to smoke, I assessed what was going on. Upon further investigating where the fire was coming from, I Could see the smoke was billowing from my rear window. As I Went to check on window heater that turns on automatically with remote start, the windows left panel exploded in my face from the outside of truck. Minor glass cuts, no major injuries. No insurance claims filed, no emergency services called as after I extinguished fire and turned off vehicle smoke seemed to have dissipated enough to safely get home 4 minutes away. As preventive messures I pulled the fuse to the rear window defroster so it is no longer getting power. This is seriously a safety hazard and thankfully I was able to pull away from gas pump. My truck, not so lucky. After looking into the issue when I got home, the US has NOT filed a recall on rear window defrosters for truck years 2014-2019. Canada DOES have a recall for this issue. As it has happened to me in the US in a very scary manor this needs to be addressed. I can’t imagine what would have happened if I was driving with kids in the rear seat. This needs to be taken care of and not at owners expense. Americans buy new vehicles to feel safe and secure. After owning my vehicle I have second thoughts about owning new, especially if a fire happens due to electronics built into the vehicle. I pray we can have this issue resolved to save all the innocent GM truck owners with families and friends who would also like to feel safe in their trucks. With temps this low in New England, I would like to be able to use my window defroster and have safer fields of view in icy/snowy conditions.

Rear defrost shorted and shattered the glass.

"Trailer Brake System Service" message continuously displays across the digital cluster menu while I drive.

2 times total electrical and engine failure while driving.

I am filing a complaint regarding an electrical fire in the junction box of my 2017 Chevy Silverado 1500. The issue began when the front passenger side marker light would not turn off. I disconnected the battery overnight to troubleshoot the problem. However, when I reconnected the battery the next morning, an electrical fire occurred in the fuse junction box under the hood. At the same time, the engine unexpectedly attempted to turn over and start on its own. I immediately disconnected the battery again to stop the fire. Upon inspection, I found that several wires, plugs, and the top half of the junction box had sustained significant damage.

As I was driving I received a call while my phone was plugged in to the USB charging port and as I answered the call all the gauges on my dash, as well as the radio and all my warning lights shut off and turned back on and calibrated as if I first started the vehicle and reset. Then the radio and things wouldn't work. I had to pull over shut off the truck and restart it. This has happened 2 times already in less than as year I contacted the dealer and they really don't seem to care and keep putting me off or telling me they will call me which never happens. As of writing this still not fixed.

My vehicle radio goes crazy, but oddly the speedometer goes away as well. I was able to get it back by turning radio off completely, but this should be a recall issue. Please help.

This is a complaint in regards to the trailer breaking system in my certified pre-owned 2017 Chevy Silverado that I purchased in April of this year, 2024. I purchased this truck in particular for its high ratings in safety and towing capabilities. (April- May 2024) While towing a 22ft trailer from Virginia to Washington state, there were several moments where the “service trailer braking system” alert would appear on the dash. Driving on the interstate for days on end is twice as stressful when you have to wonder if your trailer brakes are reliable. If the trailer brakes were to suddenly stop working it would be dangerous for me and my passengers, as well as those around me on the road. (Sept- Oct 2024) We aren’t towing a trailer anymore, but the “service trailer braking system” light has been going off every couple minutes.

We Bought a Chevy Silverado 1500 truck used in Nov 2021for purpose of towing RV trailer. In having axel bearings packed on trailer March [XXX], 2024, the RV mechanic noticed no wear or brake dust. He checked and determined RV brakes had never engaged and found no power to the RV brakes in the plug in port on back of truck. Took to dealer, Chesrown in Delaware Ohio, on [XXX], 2024. After having truck all day they said issue was brake modulator which they reprogrammed. We hooked up RV trailer and brakes still do not work. Hand brake controller on dash will engage the trailer brakes , but not the foot brake. In researching online, there is a great deal of discussion about GM knowing about and not addressing the issue. There’s a known defect in a wiring harness between two of the body control modules. This part is known for broken wires and for connective issues. We reached out to GM Customer service at 800-222-1020, who took our information and said they would contact the dealer. We took truck in today and explained again what the issue was and what we had learned from our research. There are currently several recalls on 2022 and 2023 Silverados for the same trailer brake issues. GM needs to take responsibility for this critical service issue!! We CAN NOT tow a RV trailer WITHOUT BRAKES! When we asked the service manager why the tow package was not part of the inspection process when they took the vehicle in and placed it for sale as a used vehicle, he said they don’t do that. Seems to us, that when a dealer sells a vehicle, all parts should be in working order. Especially with a factory installed tow package. PLEASE research and contact GM and have them issue a RECALL on ALL of their vehicles with factory tow packages to ensure the safety of all of those driving them! You will find numerous forums online where the biggest complaint is the trailer brake system not working and people very frustrated with the lack of response from not only GM but the dealers.
