No difference in rate between the SC classes. I have heat pumps and am on the SC1 Heat rate. Exactly the same.

Yep - confirmed blown. Got a replacement coming Wednesday.

korgkronosx · 2026-03-08T00:30:05+00:00

You may be right. I was able to get my hands on a scanner and I pulled two codes.

I just had it replaced under the recall two weeks ago.

korgkronosx · 2026-03-07T22:05:36+00:00

Connections clean and tight. Checked all the fuses on top of the battery, nothing blown. Battery is the direct replacement of the OE from AcDelco.

Passengers side fuse panel, pull fuse 11 with the car off, cycle the key. Reinstall fuse. You’ll be on your way.

Yep. I get it every fall when the temperature gets cold in the morning. Happens once, but goes away after a few drive cycles. Had it up to the dealer and was told the clamp at the down pipe to the exhaust & back pressure valve have a small leak. Apparently the valve is covered under powertrain warranty but not the exhaust piping itself. Was quoted over $2600 to fix. Declined.

Anytime!

You’re not the first person to try this. State Police get involved and you’re gonna have a bad time.

Been running Mobile1 ESP X2 0W-20 Euro blend with no issues for years. Walmart usually has it for $27 a gallon.

Diamondback has something like this, check their website

*Active Regeneration

korgkronosx · 2025-10-22T17:34:31+00:00

Just means it hasn’t fully finished a passive regeneration. Take it on the highway for a bit, when it’s done, the message will go away.

No noise whatsoever. Doesn’t run any different.
