Among the 2022 and 2023 Chevy Corvette C8’s numerous convenience features are automatic headlights that will switch on when ambient lighting conditions are appropriate. However, some Chevy Corvette owners may have noticed the headlamps switching on during the daytime. Luckily, a cause and fix for this issue have been identified.
According to a recent post from GM TechLink, the issue is present in certain 2022 Chevy Corvette and 2023 Chevy Corvette models when the headlamp switch is set to the Auto position. In affected units, the headlamps will activate during the day, rather than simply the Daytime Running Lamps.
This issue is the result of incorrect programming for the Body Control Module (BCM), which monitors ambient light levels in determining whether the Daytime Running Lamps or primary headlamps should be activated. To fix the issue, GM TechLink recommends updating the BCM software. The software update may be available via an over-the-air (OTA) programming event, and as such, it’s recommended that customers monitor the vehicle infotainment system for updates.
Critically, GM TechLink adds that a software update may not yet be available for the 2023 Chevy Corvette C8. As such, it’s recommended that 2023 Corvette customers check the headlamp switch setting, as well as the illuminated Lights On Reminder symbol on the instrument cluster in order to ensure the headlamps are active during low-lighting conditions.
It’s also worth mentioning that similar lighting issues are present for several full-size GM SUVs, including the 2022 Cadillac Escalade, 2022 GMC Yukon, 2022 Chevy Tahoe, and 2022 Chevy Suburban, as GM Authority covered previously.
As a reminder, the Chevy Corvette C8 Stingray features the naturally aspirated 6.2L V8 LT2 gasoline engine, which is rated at 490 horsepower at 6,450 rpm and 465 pound-feet of torque at 5,150 rpm. Output is routed to the rear axle by way of the GM eight-speed dual-clutch automatic transmission (M1L). Under the skin is the GM Y2 platform, while production takes place at the GM Bowling Green plant in Kentucky.

Milking this story to death arnt we for DEM CLICKS.
EVERY GLOBAL B VEHICLE has this problem.
One article. Journalism is a joke.
Wait till they find out the Infotainment updates apply to basically the whole lineup. 24 articles for one change!
In spite of the tech link, this isn’t just a software issue. People who replaced the sensors with older stock ones found the problem went away. Something changed with GM’s sensor supplier, and the newer sensors have an issue with existing software. If older sensors work properly, the issue is really with the sensor. GM’s just trying to avoid having to replace 10,000 defective sensors.
After 2 years on a waiting list, my buddy and I finally took delivery of our C8’s at the NCM in Kentucky. They were the last of the 2022’s. We drove all over Kentucky and Tennessee breaking in the new cars. We both noticed that our tail lights would go off and on intermittently while we were driving. There was no rhyme or reason to it….. totally random. The NCM bash was going on at the time and we were able to talk with some of the guest GM engineers at the event. They had no idea what was going on with this glitch. I even had PDR footage showing the randomness of this problem. I suspected a sensor, but now this article confirms my suspicions. Just ran the update yesterday so I’m not sure if it will resolve the issue or not.
We are being ‘High Teched’ into helplessness.
What’s the down low on tHe dash lights not working ,on the C8 ??
