Purchased this truck brand new in October 2022. Has 2,100 miles on it with no issues until yesterday. Was making a short trip to the store when all the sudden check engine light came on, traction control light came on, front collision light came on, dash said service ESC and then changed to service traction control. When i got up to about 25 mph it felt like i was driving over rumble strips and check engine light started flashing. I'm guessing that was limp mode kicking in ? Looking at the my chevrolet app, i have a warning for emissions system schedule service now. 2 things that i dont know if they matter or not, 99% of the time i remote start the truck. Yesterday i didnt do that so the warm up time was less than normal before pulling out and 2nd, i had a Borla Touring exhaust installed about 2 weeks ago. Anybody experience this ? Any ideas ? Will be calling dealer tomorrow to take it in.

Sounds like lifter failure. Not common on a '22.
Is your truck a Mexican truck or a Fort Wayne?
Did you have a Pulsar LT?
 
The mechanicals are still DFM in the engine. The chip shortage is why it has no DFM.

Ok, well thats good to know i guess. There wasn't anything stating of a retrofit when they became available. Not like i would have went and had it put in anyhow. Funny how i was lucky enough that my truck had ALL the chips it was supposed to except that one.
 
Hopefully for PennStateLarry it’s not lifters. But if so, now it’s all the way into 22 refresh trucks. Seems to rule out GMs “it was just a bad batch from supplier” theory. It’s also now spanning several model years. 🤦🏻‍♂️
 
Did you try pulling the negative battery cable and resetting the truck itself. I would start there.
 
So this basically means a Pulsar does nothing to help prevent lifter failure.
Yes. I've said this NUMEROUS times on NUMEROUS threads when people post about the Pulsar. There's a guy on YouTube I was following for a while with a 6.2 Trail Boss and had the Pulsar on it and his lifters failed. I can't remember if it was around 8K or 12K miles.

I did not try that. Besides everything else in my original post , I have since discovered the remote start will not work, when putting it in drive and letting it roll, there is a squeaking sound coming from the rear. Almost like the parking brake is slightly engaged and I guess because it is running so rough, I'm hearing something from the engine bay that sounds like a metal shield or something vibrating. All of the sudden its like its possessed. Hopefully I'll have an update later today. It was towed to dealer this morning.
