2024 Chevrolet Equinox electrical system problems

“Check engine light with message engine running at diminished capacity as speed would not go above 20mph. Safety at risk from other vehicles on highway until able to reach safe location. Dealer states SES light on P0089 and P228C. GM bulletin on both codes. Programmed ECM with latest calibration for codes listed. If codes come back must do further diagnostics. Concerned about repeat possibility.”

“My car seized while I was driving. It started fine and I drove about 10 min down the road and all of a sudden it seized. My car was towed to dealership. OnStar sent me a code p129f fuel pump. I was driving on the road and it seized. Could have caused a bad accident. Cars had to go around me. Yes the problem was “fixed” today 6/30. No prior error messages after is seized my battery light came on”

“The vehicle first experienced a serious malfunction on October 12, 2025, while driving on an expressway at 65 mph, and the same issue recurred on March 8, 2026, while driving on a 6-lane, busy highway at 45 mph. The condition involves the vehicle unexpectedly shutting down, rendering the acceleration pedal useless and causing the car to glide to a complete stop in traffic, creating a significant safety concern and rendering the vehicle unreliable for normal use. The vehicle has been at the Chevrolet dealership since March 8 2026 with them unable to replicate the issue. There were no warning lamps, messages, or other symptoms of the problem before the failure. I called OnStar both times it happened immediately after the incident, with neither time resulting in any negative results on the report.”

“Intella beam system turns off while driving. Radio and lights won't shut off when car is turned off. Crash detection comes on when nothing is in front of you. Dash is blank when starting the vehicle. On star not connecting and then won't turn off.”

“Vehicle Safety Complaint – 2024 Chevrolet Equinox I am reporting a safety defect involving unintended vehicle movement and improper shutdown behavior. While operating my 2024 Chevrolet Equinox, I was able to shut the vehicle off even though it was not in Park. After shutdown, the vehicle rolled forward on its own and struck a tree. At the time of the incident, the radio remained on despite the vehicle being turned off, indicating the vehicle may not have fully entered ignition-off state. This incident suggests a potential malfunction involving one or more of the following systems: gear position detection system transmission park engagement mechanism electronic shift control module ignition state logic or body control module The vehicle should not allow shutdown unless it is in Park, or it should provide clear warnings and prevent unintended movement. This behavior presents a serious safety risk of rollaway incidents. I am requesting a full diagnostic inspection and documentation of all stored fault codes, including history codes, prior to any resets. Please also check for software updates, technical service bulletins, or known defects related to shift position…”

“At 5 am in the morning the car suddenly failed and indicated it was an engine or transmission failure in the middle of a four lane major intersection in a downtown area. It was dangerous due to the darkness, and poor visibility. I had to abandon the vehicle as it was dangerous to stay with it while waiting for police. I could have been injured (as could others) due to its sudden failure in the intersection of a busy roadway. Chevrolet dealership states it is the fuel pump driver module. The car is currently at the dealership for repair. There were no warning lamps, messages or other symptoms of the problem prior to the failure until the car suddenly lost power. Once it lost power the engine light lit up and shortly after I had exited the vehicle, I began receiving messages from "On Star" telling me that there were engine or transmission problems. Meanwhile I stood in the pouring rain in an unsafe neighborhood, leaning out into traffic to try and stop cars from running head on into my car for over 30 minutes waiting for police.”
