2023 Chevrolet Suburban electrical problems

Filed Oct 29, 2026 · Driver assistance, Electrical · LA

My 2023 Chevrolet Suburban developed a "Service Driver Assist System" warning, and both the front and rear parking assistance systems stopped functioning. When approaching objects at low speeds in Drive or Reverse, the vehicle did not provide the expected parking distance warnings. I took the vehicle to an authorized Chevrolet dealership on October 22, 2026. The dealership initially attributed the problem to a low 12-volt battery and recommended replacing it. I authorized installation of a new ACDelco AGM battery. The dealer tested the charging system at 13.5 volts. However, after the battery replacement, the "Service Driver Assist System" warning remained, and the parking sensors still did not function. The service advisor initially indicated that the warning might take 12–24 hours to disappear. I returned to the dealership because the problem persisted after waited for a weekend. The parking assistance system remains inoperative, reducing the driver's ability to receive proximity warnings when maneuvering or parking near obstacles, pedestrians, or other vehicles. I am reporting this incident because the driver-assistance warning and parking sensor failure persisted after the initial repair. The underlying cause of the sensor damage has not been established.

While driving, the digital driver/instrument display behind the steering wheel went completely black, but the engine continued running and the radio remained on. The vehicle was stopped, turned off and restarted and the display screen came back on. This didn't effect the drivability of the vehicle. In some of the research I've found the cause might be an instrument-cluster software problem or an "Instrument Cluster Missing Graphics Processor". The recommended remedy would be to replace the instrument cluster. There is also one instance where the dealer reportedly determined that the instrument panel control module needed to be reset versus repaired which would not permanently resolve the issue.

The engine of this car has been under recall for multiple issues during the time we have owned it. The most recent issue that was experienced was total engine failure and electrical malfunction while driving on a busy street near train tracks. The vehicle was making a loud banging sound moments before this occurred. I wasn't even given time to get to a safe spot to investigate the issue. When it shut down, a quick message flashed across the dash board--stating ability to shift had been lost (or something to that effect)--the vehicle then flipped into neutral and immediately lost power. My safety was put at great risk due to the fact that the entire vehicle shut down moments after I crossed over a very busy railway track. The vehicle had to be towed to a nearby Chevrolet dealership where it has been confirmed there was total engine failure as well as blown main electrical fuse.

The lights flash high beam, low beam, high beam, low beam, while I’m driving. Nothing seems to keep them from doing that.

Since purchasing the car in March 2023, the battery has died 5-7 times. We contacted our dealer and they claimed nothing wrong and the battery was fine. We have contacted them about this issue and there is no fix. They performed an update in June 2025 which was supposed to fix it but it didn’t. The latest it has died is November 25. There was nothing left on for the battery to die. I have 4 children and it’s starting to get very cold outside. I live in a rural area with poor cell reception. I am worried I’ll be stranded somewhere with a new baby and 3 younger children.

My vehicle suddenly stalled while driving. I later replaced the battery and discovered the telecom module was damaged, making the OnStar system inoperable. GM disagreed with my warranty claim and required me to replace the module at my own expense. I discovered the same issue is common in various GM models from 2023-2025. My Suburban and Yukon both have the same issue, making them defective. However, GM will not provide a free replacement under warranty.

Issue: The vehicle intermittently displays a “Key Not Found” or “No Key Detected” message on the dash and refuses to start, despite both original factory-issued key fobs being present and having fresh batteries. The issue began in summer 2023 and has progressively worsened. The vehicle has stranded our family multiple times, sometimes requiring a tow, family impact, missed obligations. Luckily for all urgent needs like trips to the ER or Urgent care, we were able to use our other vehicle, but we no longer have that vehicle and it is important that our sole vehicle be a reliable one. Impact: •Two emergency room visits and multiple urgent pediatric appointments affected •Forced to rely on one family vehicle for months •Paid for tow and fob batteries •Multiple instances of no rental coverage •GM and dealers often declined documentation or action due to the issue being “intermittent” ⸻ Request: We believe there is a systemic defect in the Suburban’s keyless entry/ignition system (likely receiver or antenna module). We request that the federal safety agency investigate and that GM be required to issue a recall or permanent repair for affected models. This issue poses a safety concern and has created financial and logistical hardship for our family.
