One problem related to battery dead has been reported for the 1998 Chevrolet Tahoe. The most recently reported issues are listed below.
My battery failed where the positave post connects to it,battery acid spilled all over wire harness. My friend has a 1997 Tahoe that did the exact same thing! when I contacted costomer service, I was told that they did not know anything about this problem nor did they have any complaints. The lady finally noticed where you(NHTSA) was investigating this situation. Amazing!!!please feel free to contact me for add. Follow-ups. Thank-you. Doug catron.
