Question about the Headlights

[Drusifer]

I just received 13529378 from RA and installed it on a 2022 RST but headlights are still on in full sun. S/N 301201187. I assume this is one of the newer sensors. Frustrating.

I got a 378 sensor off eBay. Just put it on and so far it functions correctly. Was advertised as new but open box or old stock.

Always a chance something else is going on, but yeah, I think the older s/n’s are closer to starting with 15____

What was your serial number? Bought one “new” on eBay that also appears to be open box. S/N 1461105118.

Update - it worked! The DRL are probably 3x brighter than the parking lights. I didn’t fully remove the panel, just the front few clips. Slid my hand under and was able to pop one side of the sensor then removed from above.

Wondering if the stock might be replenishing? I ordered one through my local dealer a couple of weeks ago, when they said they were backordered nationally with no ETA, and they just called to say they got it in.

I too received the call from the dealer stating they had a new sensor in for my Tahoe. I’m literally at the dealer right now and the replacement sensor also has the same problem and did not correct the issue.

Crap! I was afraid of that. I'm scheduled to get mine replaced on Monday. -sigh

Update: Ordered another off eBay and the serial # started much lower (130 or something). It has been installed, and DRL and headlights now work properly. RA wouldn’t accept my return. I invested a total of about $30 between eBay and RA. Worth it to have the problem corrected.

I have a 2022 Denali XL. Ordered and purchased new in May. I have the headlamp issue as well. Took it to the dealership, they diagnosis the issue. Ordered a new sensor. 4 weeks later sensor in and they installed. Still having the same issue. Advisor and tech are reaching out to GM for help.

I am trying to do the tape mod. Can’t get the placement right. If you have done the tape mod, can you please send a photo of where your tape is placed on the sensor? Thanks for the help! Crazy issue on a $80k car.
