Guys, do you know if a Maintanace light is supposed to come on at 30,000 miles for service? I do not recall the service light ever comming on before when I was driving the car at any intervals but just got a call from wifey saying some light came on. I know the car was about to hit 30K so I am thinking that's it but just don't know about the fact if anything is supposed to come on and as usual I am worried if I can not check right away ! Is this easily reset? I am not sure if I can get the service right away.

Now after reading up on this forum I found that there is no such thing as a 30K service for an H3? if that is the case I wonder what the light is for. I just installed an aftermarket radio with a NAV unit and friday got a message about the break cable not being connected properly (on the nav screen), maybe it came loose, but can this cause a warning to come on on H3?

 

It sounds like the Check Engine light is on, is this the light that comes on for oil change/service/maintanance ? or is it a sign of some other trouble. I never had to reset any maintanance lights so not sure if this is the same light.

 

I just took my H3 in for a 30,000 mile service
No actual work needs to be done
I had an oil and filter change, rotate all tires and a check of "stuff' under the chassis
Dealer stated this is all that is called for at this mileage

 

the light that came on: was it a dollar sign and the dealership name under it!!! LMAO

 

I would call your gm dealer and find out if your warranty has expired yet so you can find out what's up with the check engine light. I have an 06 with 46k and I have exactly 6 days remaining on my warranty.
As for the services, imo I would keep an eye on your differential and tranny fluids. I know it says that its the 50 k service but it's still a 5 year old truck. I changed my fluids at 40k and they were filthy.It ran alot smoother and I gained a little gas mileage.

 

That's a very good idea mthoodh3, are these fluids easy to change or do I need to take it to a dealer/shop? Yes my warranty is already out since last november, I bought it November 2005. However, I did get an extended warranty at one point after suing GM so I have to look and see if I can find that letter. Last time I was at the dealer they asked for it for a little warranty work I wanted to do before finding out it was finished. I meant to do some kind of maintanance work on the truck anyhow so it might be a good idea, I want to do the things I can do on my own though, no way I am paying over 1K to the dealer. I also wanted to change the spark plugs and the cables but not sure how easy it is in this truck. I used to change them in my older cars but nowadays the engine is all covered up.

 

Well the light came off while my wife was driving home yesterday and stayed off thus far. Not sure what to think of it, was it some a freaky coincidence or is there a real problem, should I still go have it read to see what code it is?
