For months now, my 2018 Chevy Silverado 1500 has a -??service trailer brake system-??notification on the the dash that repeatedly pops up every 5-15 seconds while the vehicle is on, including while driving. This, along with the pinging sound that comes with the notification, makes the vehicle difficult to drive due to the constant distraction the notification makes. I have tried taking issue with the dealership but they are not helping whatsoever. From my own research online, I have seen hundreds of other people experiencing the same issue. Please help us eliminate this distraction by forcing a recall and thus making the roads safer for everyone. Thank you.

Bought the truck new. Never towed a trailer till well after warranty. Service trailer brake light keeps coming on continuously. Then no trailer lights or trailer brakes. Found 2 blown fuses but now the same thing is happening again. After my research I found tons of information that lots of other people are having the same issues. I have not pulled my RV since because I'm worried about it not having brakes. It's quite large and without them this truck would not be able to stop in case of a quick emergency.

Twice now GM has recalled the block heater for my truck. The first remedy did not fix the issue and had to be recalled again. This was back in July 2021. It is now the end of November 2021 and nothing more has been done. My truck requires a block heater in order to start in the upcoming cold months. This will make two years in a row I cannot use my truck when the temperatures fall below freezing. It directly affects my livelihood because I need a truck for work. What more can I do to speed this process up" How is it GM can still sell new diesel pickups with working block heaters, but are not required to fix the older diesel pickups"

Trailer brake system failure we noticed the sudden drainage of power resulting in death of battery multiple times alert was present after we notice the loss in voltage in battery to battery drainage after research I found that it is usually a short or a bad wiring harness which causes this and could pose a danger considering how I at one point in time have trilled things this could be an issue and a danger to others on the road

The DIC and infotainment both change settings on their own. It will change radio stations or call people on the infotainment and the DIC will change information displayed. The safety issue is it will also flash that the trailer has been disconnected/connected and when it thinks the trailer has been disconnected the trailer brakes will fail to function. It is a known problem with the display issue but I am unaware of any reports on trailer brake function. I have had a few serious conditions on two trailers when the truck does not recognize the trailer being connected and fails to apply the brakes.

At slow speeds, such as when parking, the truck's electrical system shuts down, I lose power steering, dash lights, radio, and then the truck restarts itself and continues. This has happened multiple times and Chevrolet dealers don't w what the problem is. If nearly collided twice due to lack of power steering.

While waiting to order a morning coffee at a local coffee shop drive thru (stationary), the rear defrost/defogger caused one of the glass panels of the rear windshield/back glass to shatter/explode. There was also smoke & an unmistakable electrical burning smell present at that time. Please refer to GM Canada recall N192220470, as I believe this should become a safety recall in the United States of America as well.

  • 18,000 miles
When the vehicle was started, a loud squealing sound was heard coming from the vicinity of the front of the engine. While under the oem bumper to bumper warranted period, Chevrolet dealer number one was not able to determine the problem or repair it. Furthermore, the problem was not reported in the vehicle history as reported. A short period later, Chevrolet dealer number two was able to locate the problem and repair it at my personal expense as the warranted expired on time as opposed to mileage. I learned that the same problem was a part of a previous recall which dealt with failure of the brake assist pump. GM rectified the recall by changing the computer software to overdrive the pump beyond it's original design speed. This provided an increase in pressure which temporarily corrected the failure. The corrective action added more stress to the original design of the pump and now the pump is mechanically failing as a result. This failure could potentially cause an immediate unexpected brake failure potentially resulting in frontal collision and loss of life!. the dealers have not provided copies of service orders or replaced parts. I only have rental agreements to substantiate that something was done to the vehicle. GM's customer care is investigating the unprecedented behavior of the franchised dealers with no reply to me at this time.

While driving at approximately 65 mph all electronics shut off and turned back on moments later. This includes the gauges, radio and all lights including headlights. I took it to the dealership in which I purchased the truck from. They diagnosed it as a low voltage battery and their solution was to charge the battery and retest the systems. However they could not tell me why it was low. The service manager would not look into further testing to check the issue as they had met all the necessary steps layed out by GM under the bumper to bumper warranty. He had told me that they would be happy to do further testing on why the battery had a low voltage condition if I were to pay out of pocket for the costs even though my truck is still under bumper bumper warrenty. The service manager also blammed the cold weather conditions as it is currently in the low 20's outside. I have issue with this diagnosis due to me driving 60 miles a day for work and another 30 miles to drop it off at the dealership, the battery should have been amply charged in that time for their testing. Also the dealership replaced the battery with a new one 8 months prior when I first purchased the truck. I am concerned for my safety as the headlights turned off without warning due to a low battery and there has been no proper diagnosis of why there is a low battery condition.

Truck will lose all power, everything will shut off, and then come right back on. It has happened while accelerating into traffic, slowing down turning right and turning left, and while moving straight ahead. It has been in the shop once for this same issue and they tell me they cannot find anything wrong with it. The stabilitrac warning will come on and go off and have had stall warning flash in traffic at stop lights. This has been going on for the last 12,000 miles and I have 20,083 miles on truck now. The clock and radio reset. It shutdown pulling into traffic on a busy highway and was a very dangerous situation. Been trying to get it into dealership since 3 weeks ago and no luck. This is not the only issues with this truck.
