Reciently the Check Engine Lamp (MIL) came on at start and remainded on with no noticable engine running rough. The error codes were read which indicated 400+ Cold Start error codes on Cylinder No.3. Their are several GM Service Bulletins (PIP5498M, PIP5628E) on this subject V8 on engines from 2000-2022. The bulletins indicate the "Cold Start" causes misfires due to coolant entering the at the liner to deck face casting or the casting line in the intake port of the cylinder head, in my case No. 3. The GM Service bulletins indicate "engine replacement" is needed to fix this problem. I have been very happy about this vehicle however, at 67K miles, this type of issue should NOT be occuring. Apparently GM has know about this problem since 2000-2020 model years described on the attached Service Bulletins.
After Two days of MIL being ON, the lamp is now OFF. My question is how can the problem described repair itself and could the diagonistic codes be attributed to another problem? I was under the impression that once the diagonistic code is initiated, the only method of turning OFF the MIL is by resetting or clearing the codes.
Hey everyone. I have a 2016 Sierra Denali. A while back I opted to do away with the magnaride struts and installed BIlstein 6112s in the front with Cognito UCAs and BIlstein 5100s in the rear, also added Xineering bypass kit to clear the Magnaride errors. I had an issue recently with the stop mount on the drivers side strut blowing out. I contacted BIlstein about it and the rep told me he thought he had been told that the distance between the LCA and where the strut mounts into the truck frame at the top on a magnaride equipped Denali is shorter than a normal Sierra and that it was possible that the strut was too compressed, causing it to push through the top mount. Has anyone ever heard this or experienced this issue? I can’t find anything mentioned about it anywhere. I’m taking the truck in next week to get it fixed but if it’s going to just happen again I am wondering if I need to get different struts all together.

Hello I'm having a problem with these headlight that I installed on my 2015 GMC Sierra. I install the newer Denali headlight the blinker light stay on and when I turn on the driver side blinker it flashes the high beams and stuff. I need some advice the harness I use was from GEN5
Like new, Pulsar LT for sale, bought direct from manufacturer. Box is included as well, just can't upload a pic of it for some reason.
Had this installed on my 2021 Chevrolet Silverado, took this off when I traded it in. Works great, ~10 months of ownership.
Looking for $400, shipping included, within USA. Venmo/Paypal/Zelle preferred.
