2024 Chevrolet Tahoe: check engine light

Filed Sep 17, 2026 · CA

I own a 2024 Chevrolet Tahoe RST and have experienced recurring electronic/electrical problems despite multiple dealership visits. The vehicle repeatedly displays “Open Then Close” window messages for the passenger or driver window even though the windows function normally. While driving, the infotainment screen has repeatedly gone black, causing the audio/music and audible turn-signal indicator/chime to stop working. On one occasion while stopped at a red light with the vehicle running, the infotainment screen and entire instrument cluster went blank and rebooted. The Chevrolet logo remained displayed during the restart, and the audio and turn-signal chime stopped working. The dealership has been unable to duplicate the issue but has performed software updates. The problems continue. Most recently, the vehicle displayed “Service Transmission Now — Unable to Shift Soon.” The warning disappeared. The dealership then stated the 12-volt battery was low and needed replacement before accurate diagnostics could be performed. I replaced the battery, and afterward the check-engine light came on. A complete diagnostic has not yet been performed because my appointment was rescheduled. I am concerned these recurring electrical/electronic issues, transmission warning, and check-engine light may indicate an underlying safety-related defect. I am requesting that GM formally document and investigate these concerns.

Dealer checked the 6.2L motor for known defects. It "passed" inspection on 11/20/25 and got the thicker oil (OW-40). The engine lost propulsion ("died") 3 times on a 55mph State Highway on 02/09/26 with my 4 year old in the car with me. It died and came to a complete stop in one lane and would not re-start initially with cars almost rear ending us and needing to aggressively swerve to avoid hitting us. After 4 or 5 attempts it started again (making terrible grinding noises) so I could get it off the road before it died again. It started again to drive home on the back roads approximately 1 mile. Low oil pressure and check engine lights came on. I also received notifications from onstar and from the my Chevy app that there were severe motor or transmission problems. I scanned it with an OBD II Scanner and it has code P00016 (Camshaft Position Correlation - Bank 1 Sensor A). It got towed to the dealer and is now confirmed it is in need of a full motor replacement less than 3 months after they told me the motor passed inspection! This is not acceptable. To be told it's fine and then have it fail with my child in the car is extremely unsafe. Now I'm stuck trying to get a comparable loaner vehicle from the dealer to drive in the snow and mountains with my family safely while they expect to have the vehicle at minimum of 6 weeks. So far they have not found a loaner potentially putting my family in further danger by not having a 4X4 vehicle in a snowy climate.

On one morning w/20 something temperature, Tahoe started and immediately shut down. When restarted, multiple malfunction lights were lit: engine, ABS/brake, steering column, traction control, etc. Reached Onstar for advice to see if Tahoe was drive-able, but only got confirmation of system malfunctions and offered roadside assistance but declined since at home and would call back if needed. About an hour later and several restarts, all malfunction lights finally cleared except engine light, which stayed on for another day or so. Tahoe drove okay during engine light on.

Check engine light turned on last week after pumping gas. After driving a certain amount of miles it turned off. I pumped gas yesterday and I’ve driven miles and it still shows it has a full tank but my Chevrolet app shows it has 85% fuel.
