2023 Chevrolet Silverado Reliability Report

The main theme is stalling while driving. The truck loses power, shuts off, or slips into neutral in traffic, sometimes with a string of warning lights and sometimes with none, and some trucks will not restart. Other reports describe burning about 2 quarts of oil between changes, a leak at the rear sliding window that stains the headliner, OnStar and Wi-Fi failures, erratic navigation, and brief rear-wheel lockups at speed. Two complaints describe the truck catching fire, one of them while idling.

Most of these filings are about the engine recall, not a new failure. Owners say the recall repair was not yet available and the wait had gone on too long. When failures do occur, the engine stalls at speed or seizes, sometimes after the recall fix of thicker oil. Some replacement engines knock or tick. A few reports cover a coolant sensor fault followed by overheating and a stall. Another describes a leaking water pump with parts on backorder for more than 45 days.

The brake pedal sinks to the floor or the brakes stop working, sometimes with a "Brake System Failure" warning and sometimes with none. Two crashes followed this kind of failure at low speed, and one caused an injury. Other reports describe longer stopping distances with the ABS light on, and front pads worn to metal around 20,000 miles. Automatic braking can falsely lock the truck in park while backing out. One brake recall is still waiting on parts.

The front turn signal and daytime running lamp fail on and off, mostly on the left side. A "Check Left Front Turn Lamp" message appears and the rear signal flashes fast. The fault often clears after a restart, so dealers have trouble confirming it. One dealer blames software. Another says the next step is replacing the headlight assembly, which cannot be serviced separately. Failures show up as early as 4,000 miles. A couple of reports describe all lights briefly cutting out while driving.

The tailgate opens on its own, both parked and on the road. It dumps cargo onto the roadway and strikes cars parked behind the truck. Some owners say a tailgate latch recall does not cover their trucks. On a 2500, the tailgate step cycles in and out because of water damage at about 41,000 miles. In one report, a hood latch broke on the freeway and the hood flew off. One fire report points to the firewall area behind the dash.

The most common complaint is phantom hard braking at highway speed with nothing ahead. It can also happen when passing cars parked on the shoulder. Adaptive cruise control is involved in both crashes. In one, the truck accelerated from a stop into the vehicle ahead with no warning. The other happened while driving into bright morning sun. One owner says collision warning and cruise control stopped working after a routine dealer service and needed a second visit.

Power steering assist cuts out suddenly and the wheel becomes hard to turn. One case ends in a crash into a tree with arm injuries. Another happens at interstate speed but ends safely on a straight road. Other reports describe the truck swaying on grooved pavement, worse when towing, which a dealer blames on the factory tires. One owner reports a steady pull to the left that three dealer visits did not fix. Another describes a stall caused by the fuel pump control module.
