Sh!t happens. Relax.

Lost my battery at 20mos and 11k miles. Replaced free at dealer. If one goes out of warranty I'll use AAA as they have a 3 year no questions asked. I'm pretty sure the alternator on newer vehicles is multistage and doesn't fully charge all the time. To save gas, but it kills batteries. Stupid epa Sent from my SM-G965U using Tapatalk

This is how I fixed it. After the C1 re-learn it was 100% better. Decided to do the C4 learn too to be 100% sure. Took about 30 minutes early one saturday morning when there was no traffic. https://gm.oemdtc.com/6777/16-na-019-information-on-transmission-adaptive-functions-and-correcting-low-mileage-harsh-shifts-slips-or-flares-2016-2017-buick-cadillac-chevrolet-gmc To Learn C1 (For 6-7 or 3-1 Shift) Pressure Learns: Note: It is recommended to utilize a road with a speed limit between of 30-45 mph (48-72 km/h) for this procedure.

Didn't mean to bump this thread...was trying to post in another...

Going to try this today after work. Sent from my SM-G965U using Tapatalk

Is this the 8 speed? Sounds exactly like the issue I had with my 16. Sent from my SM-G965U using Tapatalk

I had what I thought was a dash squeek that drove me nuts for a year. It was one of the battery bracket bolts that had gotten loose under the hood. Figured that out when I shut the door and heard it outside the truck. Sent from my SM-G965U using Tapatalk

Sounds like you've already had 2 of the same truck. Why bother? Sent from my SM-G965U using Tapatalk

You can take it to a local autoparts store and they will plug in their OBD2 reader for free and give you the codes. Or you can spend $100 at the dealer to do it if you're not under warranty. Seems like you should still be under powertrain/emissions warranty though.

Did you pull the codes? It won't come on for maintenance items. It's most likely part of the emissions system.(gas cap, O2 sensors)

Very cool. Thanks. I need to stop reading these reviews. Only have 20k on mine lol.

This happened to me today. Wtf!!! Sent from my SM-G965U using Tapatalk

Doesn't matter if you use premium or not.
