2004 Honda Odyssey van. The ignition switch and turn signal switch fail to operate correctly. The turn signal switch assembly had to be replaced by the local dealership because the relay switch in the steering column would begin to activate while driving producing an electric odor. The turn signal relay switch was replaced at approx 110,000 miles. The ignition switch is now being replaced because the ignition key cannot be inserted to start the car routinely without being manipulated. When this car was relatively new and under warranty the fan switch had to be replaced. The car now has 150,000 miles. My concern is that the electrical components in the steering column are defective and that the turn signal relay switch had the potential to burn; and the ignition switch could fail during operation of the car. The ignition switch is a defective part, or the part is from an a prior recall of 1999 to 2003 ignition switch's recalled by Honda that were used in later year models. Potentially, the 2004 models should have been included in any recalls of the ignition switches.
