I have a class C Winnebago (Chalet). The "Check Engine" light came on almost exactly at 80,000 miles. Is this automatic? I had a Dodge pickup and that happened at 60K miles. (The AUTOMATIC light.) I may call the dealer Monday, but just wondering if anyone has experienced this....Bob

It could be that it is an automatic notice to do something. I owned a 1995 Geo Tracker that had just that. Mine came on at 60k, 80k, 100k, and 120k. Here is more chatter on mine - Geo Tracker "check engine light". The other suggestions will help you determine that.
