CHEVROLET Complaints

Email Subject I am reporting a serious safety-related defect involving sudden and complete vehicle shutdown while driving in a 2024 Chevrolet Silverado EV RST. Component/System Involved: The failure appears related to the 12-volt electrical system and associated vehicle control electronics. When the vehicle detects the 12V battery as dead or critically low, it immediately disables propulsion and control systems. The exact failed component is UNKNOWN. The vehicle is available for inspection upon request. Incident Description: This failure has occurred twice under similar conditions (ambient temperature approximately 25°F). On November 28, 2024 and again on January 2, 2026, after driving approximately two blocks at low residential speeds, the vehicle abruptly and completely shut down while in motion. In both incidents, the shutdown was immediate, without warning, and accompanied by a loud thud and an extremely abrupt stop. Safety Risk: In both incidents, the vehicle became completely immobilized in the roadway. I was unable to steer to the side of the road, restart the vehicle, or shift it into gear to move it out of traffic. This created a significant risk of collision. A similar failure at highway speeds could result in a severe or fatal crash. Warnings or Prior Symptoms: No warning lamps, messages, alerts, or other symptoms appeared prior to either shutdown. Problem Confirmation or Reproduction: The issue has occurred twice under cold-weather conditions. Inspections: After the first incident, the 12V battery was inspected and no issues were found. Following the second incident, the vehicle is currently being inspected at a Chevrolet dealership. No police or insurance inspections were performed. This behavior suggests the vehicle lacks a fail-safe or degraded-operation mode for 12V system failure and instead performs an immediate shutdown while in motion, which may represent a serious safety defect warranting investigation.

The windshield is a major safety issue. It is distorted, warped, and wavy. The dealership has ordered a replacement, but I’m worried it will be the same. As for the blind spot warning, it flashes when there is nothing present. The dealership cannot replicate, and I am not able to record when driving.

I am on 20 service calls.Mine is currently having onstar issues screens glitching, Apple CarPlay won’t connect, sensors on mirrors are going off nothing beside me, when I hit my breaks it keeps turning my emergency brake on and engine power reduced keeps coming on dash but the dealership is saying GM said my warranty is voided due to a aftermarket part

Both the front AND REAR exhaust pipes are cracked and broken with holes in them where the SINGLE bracket that secures both pipes mounts. There was special coverage issued to repair, but the special coverage only identifies the front pipe. The rear pipe is essentially dangling from the upstream catalytic converter, which also appears to be cracked due to the same underlying issue. If the vehicle doors are open, exhaust fumes will enter, rather than be expelled to the rear of vehicle. This pipe can essentially finish cracking and fall off into the roadway. The check engine light did not come on until these components broke. The problem is vast across many of these vehicles as reported to me by an owner of an independent service center as well as technicians who work at certified GM dealerships. The vehicle is available for inspection upon request. I currently still drive it, but its just a matter of time before a heaping hunk of metal pipe falls onto the roadway and causes an accident. The rear pipe is almost completely separated from the remaining exhaust pipe between the upstream and downstream catalytic converters at the bracket location before the flex pipe.

We were driving on a busy freeway and the power steering quit working making it hard to steer and maneuver in traffic. We went directly to a GM dealer and the code CO545 Steering Wheel Torgue Sensor came up. This is a sensor inside the sealed steering gear that cannot be replaced without being completely removing and replaced. The cost is over $2000 and not covered under warranty. We will not be purchasing GM products any longer.
