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.

2023 Chevrolet Suburban electrical problems

The failure pattern owners describe
Buyer takeaway: The 2023 Suburban has multiple electrical system failures reported by owners: keyless entry that won't work, instrument panels going dark at highway speeds, batteries dying repeatedly, and engines shutting off without warning. Dealers struggle to diagnose and fix these issues, leaving owners stranded.
Owners of 2023 Suburbans report a cluster of serious electrical failures. The most recurring issue is the keyless entry system refusing to work despite functioning fobs with fresh batteries—one owner's family got stranded multiple times, missing medical appointments. The vehicle can also lose all electrical power to the instrument panel or entire electrical system while driving at highway speeds, with some owners experiencing complete engine shutdown and loss of all lights while in traffic.
Battery drain is another persistent complaint: one owner's battery died 5-7 times in less than two years, with the dealer unable to identify or fix the problem even after a software update. Several owners report the OnStar telecom module failing, affecting safety functions and communication systems, with GM denying warranty coverage.
Additional electrical gremlins include headlights and wipers shutting off simultaneously during highway driving in rain, computer systems throwing false error codes, and headlights flickering repeatedly between high and low beam while driving. Dealers consistently cannot reproduce these intermittent failures, leaving owners unprotected. One owner reports the same OnStar module failure is widespread across GM vehicles from 2023-2025.
