I've read some other threads on this but looking for guidance. My 09 burb (LTZ) is displaying this message (Service Suspension Soon) I'd say about 70% of the time. Occasionally, on start up, I'll hear the compressor kick in and no message. Othertimes, no compressor and this message.

I first got the message when driving and I went over a serious rough patch of road, the message came on. I ignored it, seemed fine for a few weeks, and is progressively getting worse.

I can of course take it in, but I'm wondering if the rough road maybe knocked something loose. I can see the compressor near the driver's rear wheel, not sure what to really check. I'd hate to spent $$ on a diagnostic (and recommendation to replace something that might not need to be replaced) if it's a loose connection someplace.

Any suggestions? Any recommendations on a service manual? Or should I just suck it up and take it in?

Thanks!

Best service manual is the GM FSM from Helm, Inc.

I would recommend taking the vehicle into the dealership. The vehicle seems to be still within warranty. The dealer will be able to diagnose and/or repair this issue for you. Let us know what you find out.
