“Check engine light came on my 2002 Chevrolet trailblazer (86,000 miles). Team Chevrolet analyzed and advised the gas tank is cracked. This same problem occurred at 12,000 miles but was repaired for free as vehicle was under warranty and there was an alert issued for this problem. However, the alert policy ran out at 70,000 miles so the dealership, nor GM will cover the estimated expenses of $850. I protested that this was a known and repeated problem and a fire/safety issue but they are not willing to assist in any way.”
