1996 Chevrolet Impala Engine Problems

Your heater stops working every winter, even though the dealer flushed or replaced the heater core multiple times while your car was under warranty. The problem has returned, but the dealer won't help anymore because your warranty expired—despite having service records showing this is a recurring issue. You've spoken with other owners of the same year and model experiencing the identical problem, suggesting this may be a design defect rather than a one-off failure. Fixing this will likely require the heater core to be flushed again or replaced entirely.
