The worst problem I have with this vehicle is that it will cut power to propulsion without any warning. I was driving down a suburban roadway, not on the freeway, thank God. When the truck's automatic gear shift wouldn't engage, I went from going 30 mph to 5 mph in seconds. The accelerator pedal wouldn't respond, I managed to coax my truck into a parking lot and restart the engine. Other times the head lights will not come on. Just today, I turned on the left turn signal and the Stabilitrack warning light came on, plus the radio made a brief noise of static. This particular issue appeared and disappeared in one second. I'm concerned that these problems are a manufacturer's mistake, and I want it fixed as soon as possible. My mechanic has tried repeatedly to find the cause but has been unsuccessful.

**randomly at any given speed ** First the radio system will randomly turn off then moments later… stabiliTrak off flashes followed by abs and traction control lights on dash then suddenly my Chevrolet Silverado has a mind of its own ! The door locks will flicker uncontrollably , and the vehicle just suddenly has a loss of power while rpms and gauges are continuously moving while you are unable to even move the vehicle .. this is a ongoing problem since 2019 , that no one seems to have an answer too .. I’ve taken it to 3 different mechanics and still no answers … when it first started happening it was super random and would happen a few times a day but then not happen for months on end then all of the sudden now it is happening several days a week .. I’m currently scared to even drive it which is horrible considering the amount of money I’ve put into this truck .. it has only 100k miles but somehow I am stuck using my dads old truck with 330k miles on it which seems to be more reliable and is 12 years older … sucks to pay over 500$ a month for “ your dream vehicle “ that you can’t even drive or get any real answers to what or where the problem is coming from … seems that thousands of people online have the same problem but yet no one has any solution .. Now that I’ve almost been in 3 serious accidents I decided I have to say something, 2 of these times were over 70 mph on a California freeway !!! Something must be done !

1 owner. Never driven on salted roads(south louisiana).live 100 miles from coastline,not in a saltwater environment. Or driven in water other than rain. Cruise control dropping out, automatic transmission not shifting when supposed to. Traction control dropping out, service messages cycling in and out--traction control, stabilitrac , anti-lock brakes, check engine light, red brake light comes on and off. Speedometer going crazy. Brought vehicle to gm dealer for inspection/repair. Cause- internal failure of ecbm-electronic brake control module, due to corrosion in the connector due to water intrusion. Had to replace the module, and the vehicle chassis wiring harness. Total repair was $1,830.39 for parts and labor. The dealer reported to me that the design/installation location of this module is flawed, and a faulty design allowed moisture to get into the module thru the connector.which also resulted in the wiring harness connections into the ecbm also becoming corroded.. Dealer also told me that this faulty design will eventually become a recall, and for me to keep my invoice of this repair, as to be able to claim a reimbursement for this repair.

The driver's side headlamp wiring is faulty. I have continually replaced headlamps, only to have them need replacing in a month or two.

I have had an ongoing problem with the electrical system in my truck. First time it happened I was leaving my house and as soon as I got a few houses down the road my door locks started unlocking and locking themselves over and over and the speedometer gauge was all over the place along with the RPM gauge and the road up would turn off and on and the brakes would lock up and then release and it did this until I was able to pull over and turn the truck off. Once the truck was off it wouldn't start again. I had taken the battery out to be tested and it was fine. The alternator was fine and as far as I could see the negative and positive cables from the battery were clean too. I've traced the ground and it doesn't appear to be in bad shape either. Well after I was able to get it back to my house it sat for a few days and after a couple days it randomly started back up. Took it to the local chevy dealership and they said there is no problem everything is good and they couldn't recreate the problem. They said it could be the aftermarket head unit. Well once I got my truck back the head unit no longer works or gets power? Well now a month later same problem and the truck is totally dead but battery and etc is fine.

Stability control alarm blinking ,traction control alarm blinking,, speedometer going erratic, brake lite staying in alarm,cruise control dropping out,power loss temporarily. Shifting between gears (auto xmission) was very rough.this was an electrical system that grew steadily worse. Gm dealership had to replace the ebcm, and the chassis wiringharness. Severe corrosion. Vehicle never driven in salted roads,never flooded,never driven thru water. The location of the ebcm is poorly designed. Dealership said they have never seen a module this corroded,as it was in pieces when they pulled and opened it. I waited 4 months to get it fixed, as a early mechanic saw an electrical fault, but couldn't pinpoint it as it wasn't staying in fault. He said it needed to get worse before it could be properly diagnosed. Had to bring to dealer for repair as it got progressively worse. Cost me $1878.36 to get repaired.
