I have a 2023 with the same issue and seemingly getting the friendly "not sure what to do" from the dealers, but can't blame them. GM needs to figure this out and give the dealers the info to solve this problem. First failure at approximately 32K last November while driving on highway, failure is exactly as you described. The operation resumed about 5 minutes later. Second failure was June 2025, 37K miles failure was after a fuel stop after extended period of highway driving in the rain. Original windshield, never wrecked always dealer serviced.....not sure what to do. I filed NHTSA report. Have you had any luck with getting a resolution?I'm the Original Poster. So, after my 3rd windshield wiper module, the intermittent failure still exists. I discussed with a lawyer and sent in a Lemon Law letter. They acknowledged the letter and flew out a technician to work on the truck. After a day of working on the truck he didn't find anything wrong and didn't make any repairs. GM then acknowledged that the wipers were not repaired. GM Customer Care filed for Repurchase of the truck and then denied it (because they said my initial service was over 24k miles - this was incorrect as it was 11k miles -- see my opening post of this thread). Once I sent in the service record docs, they filed for Repurchase again and denied it because they said that each service appointment was only for 1 day. This too was incorrect, but either way, I still didn't leave the service station with repaired wipers.
So, now my lawyer is looking to file a class-action lawsuit over this issue and is looking of other owners that have faced the same issue. If you have had the same issue, please let me know -- reply here, or send me a message and I'll get back to you.
I know you've been offline for some time but wondering what your resolution was to this? I took a round trip from Houston to Austin this weekend and this issues happened to me as well. Stopped working TWICE within 2 hours. The first time I was driving 75mph so it wasn't too bad. The 2nd time it happened as I was driving through a small town and luckily I was already pulling off for a pit stop. When I got back into the truck, it was still disabled and not working no matter what I tried. About 5 mins later it started working before I left the gas station. I was nervous for the rest of the trip since there was still light rain for the trip back to Houston.I'm the Original Poster.

I have logged NHTSA compliant. While doing that I was searching around I found an interesting file of an engineering report apparently filed by GM (Attached). I'm still dumbfounded that there is not some sort of resolution on this issue. I have worked in the auto industry for many years in the Detroit metro area and at one point supported a serious safety recall within the steering system of a vehicle. One vehicle showed the issue on the road and 30K+ vehicles were recalled. Someone out there has to have some connections to help us resolve this. Your comment on RainX is how we were able to continue on a family trip when the wipers decided to fail, 4hrs from home on a rainy Sunday afternoon, pulling a boat,2 kids, 2 dogs... Unreal that I'm dealing with this on a $60K+ vehicle. Lawyers help us do some digging, the doc I found seems to make it obvious that there is an issue. How is it our fault that they don't know why or what to do, just because not enough people have filed claims.Late to the thread, but I'd recommend keeping RainX fresh on your windshield if you see this failure. Might save your life.
Good luck with lawsuit.
