Has anyone had their engine warning lights go on without their being a real problem? About a monthe ago my check engine light came on. I took it do the dealer and had it checked. After 5 hours, nothing showed up and the light was reset.Five days ago, the digital readout said check 4wd (this went off and on for 2 days).Next the light said check airbag (this went on for 1 day). I had the car battery checked and put in a new one (the old one blew up during testing. Glad it did not do it in my truck).I am almost sure that it was just the battery, but just wanted input fom other H2 owners. This had never happened with any of my other new cars before.

if there is a next time use OnStar to do on road tests...cusious to see how much they can find out. I have never seen anything like that...however...my old Jeep used to do things like that all the time. It started to be a joke to me.

At times my amp would not turn on either and I was getting service messages. I doubt you will have the problems now that you have a new battery.

Of course, I say that but I put a new Optima battery in mine and the same thing started happening again. The new Optima turned out to be bad also. Chance are, though, that you are done with those problems.
