Service Leveling System

So far our HC hasn’t had any more issues since the service was done but I’ll keep an eye out and report back to you guys.

My Tahoe was back at the dealer for a few weeks in December, and they had a "GM engineer" come look at it twice. They had already replaced the level control module and the solenoid module, but the dealership had not been authorized to replace any further parts. Eventually they were told to replace the compressor. I have had the vehicle back and driven it probably 75-ish miles, and no further warning messages. So I am hopeful that it is solved!

Thanks all! Did the issue also cause your vehicle to go to Limp Mode where it wouldn't go over 56 mph?

No, I never saw a limp mode condition. The suspension would not accept height change settings, and at least one time it felt a bit more harsh like the shocks were at higher pressure. But I could always keep driving.
