The wife tried to start her new Tahoe (1800 miles) today after a quick trip around town. CEL came on P0E32 and P0E37. I had to bring the second key fob to her and it struggled to start but acts normal driving now. Checked the voltage while running and it’s 12.8 give or take. There was a light rain but we’ve driven it in the rain multiple times. I don’t think it was the key fob either but I can’t find these cel codes online to get an idea on what’s going on. Anyone have these codes before? Taking it to the dealer in the morning.

Only 12.8V at the battery when running? Should be ~14V measured at the battery when running (alternator charging).
Alternator has a sensor on it I was told. Fluctuates from 12.8 to 14+ when needed

When was truck made vs delivery? Maybe the battery went bad if was sitting waiting for chips to be installed. Bad ground
Made early November and received middle December. It’s been fine the last 1800 miles. Maybe it is just the battery. I can’t find the cel codes anywhere so we’ll see what they say at the dealership tomorrow
Does the battery have a date on it? Have it load tested?
I’ll have them do it in the morning when it’s dropped off. I haven’t had a lot of time to dig into it. It’s running and driving for now
Exact same thing happened to me yesterday morning (1/25/2022). Tahoe started with remote start, then would not start when I tried after getting in (about 5 minutes later). Eventually started after I walked away and waited about 10 minutes. Same codes, P0E32 and P0E37. Took it into the dealer - they found bulletin #PIT5873 - ticket says "engineering is working on a fix in the future". They cleared the codes and returned the vehicle.
Farmer10 - did you get a better resolution from the dealer?

That’s exactly what they told me as well

Did she remote start it? There's a thread on here about remote problems.
