One problem related to car will not start has been reported for the 1996 Chevrolet Tahoe. The most recently reported issues are listed below.
The problem I had is similar to one you are investigating against Chevrolet. My vehicle wouldn't start and it was discovered that the battery leaked acid and I had to have the battery assembly, terminals and battery replaced. I just wanted to add my complaint to the 200+ you have so far. Please feel free to contact me if you'd like. Thank you.
