2018 Chevrolet Silverado 1500: multiple warning lights

Filed Aug 21, 2026 · Electrical · NC

i was driving down the highway, turned on left signal to make left turn. the truck engine died with no warning, could not steer, almost ran into bank. all the dash lights went black, no power at all. the radio starts playing on occasion without being turned on. the clock loses time when it wants to.the blower on the ac comes on and off when it wants to.have had battery, alternator, ignition system checked. all these check out just fine. there were no codes , and absolutely no lights or warnings on dash. our truck was still in the highway lane. luckily the police stopped and assisted by directing and holding up traffic as necessary. i have had similar issues on other occasions but was always more brief and the truck would crank back up right away.

GM has produced millions of vehicles with the 5.3 motor with AFM,DOD,VVT issues. They are well aware of this issue. The factory defect causes the lifters to collapse causing catastrophic engine failure. This posses a hazard to consumers in traffic trying to navigate their stalled vehicles off the roadways. GM customer service is rude and dismissive, furthermore they offer no assistance to fix these problems. The issues with these motors is well documented and any repair shop/ dealership can confirm these issues. There is no indication from warning systems prior to this failure. However there are multiple Dash warning lights after the catastrophic failure occurs. The cost is passed to consumers to address these issues.

Driving on highway 70 mph with out prior warning the truck begins to shake, backfire, lunging, loss of power, all the lights on the dash starting going crazy, cars behind me trying to avoid hitting me ,it wouldn't speed up, having a hard time getting it off the road and out of the way of highway traffic before getting rear ended by traffic behind me. The truck only has a little over 60000 miles on it which is just beyond the 60000 mile warranty, The truck lost compression because of a lifter failure in the motor. After this I have no interest in ever buying another Chevy product, If they cant build a motor that will last more than 3 years maybe they should rethink their future in the auto industry.

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.
