This sounds stupid, but it happens to me.

Cut thru the crap, check the operating temp, if running less than 195 degrees replace the thermostat clear codes and road test.

This is a knock sensor code

  Probably not their first rodeo, so it should go as planned most likely. Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together. We usually put 50-100mi before we hand them back so if something happens, its not after you get it. A coolant leaks, oil leaks, a ground left off or loose, vibration, etc. The new engines so far have been good? There's been a couple that have popped out there again (the replacement engine) but most have been okay.
- Different requirements for oil filters?

  To me it honestly makes zero difference what filter you run. It's not a race engine, just a truck engine that's mostly bumming highways and it just needs a filter that filters oil. The filter used to be a 7060 and the long version was a 7045. Now it's the newer updated filter that the K2XX trucks and newer run, the 100255 I believe if we are using napa numbers. Any of those filters is going to do the job. I wouldn't overthink it, to me it makes no difference because those first filter numbers worked for 18+ years before the spec suddenly changed.
- No 12v outlets in 2026 gmc Sierra

  My phone (OnePlus) requires a proprietary charger to get the full 80w fast charging benefits. The only option to get these fast charging benefits is a 12v plug. Any other charger and my phone defaults to 25w charging. I also have a tire inflator with a back up 12v plug. USB would never keep that thing going in a pinch. Putting just one in the trucks wouldn't hurt. Good laptops still include at least 1 USB-a port.
- Chirping/squeaking coming from under dash when driving over bumps

  2017 Sierra 1500 SLT I read that there’s a bolt on the battery brace that sometimes gets loose. I checked all the bolts around there that I could, and all were tight. This sounds more like it’s under the dash, maybe closer to the driver footwell. Anyone else have this problem, or know a possible cause? https://imgur.com/a/kaQRZZH
