The 1996 Audi A4 has 6 recalls, the most serious being a cracked ignition switch housing that can leave the key stuck between the start and run positions, cutting power to the wipers and headlights while driving.
The ignition switch issue appears across multiple filings but describes the same underlying problem: a spring anchor point in the switch housing can crack, preventing the key from rotating back to the running position after the engine starts. When that happens, electrical accessories including the windshield wipers and headlights go dead, reducing visibility in rain or darkness without warning. Prior repair attempts do not appear to have fully resolved the issue, which is why it surfaces across several campaigns.
The remaining recall covers an intermittent horn caused by a poor electrical ground connection at the steering wheel. When the ground contact is weak, the horn may fail to sound at all or cut out mid-use, leaving the driver without a way to signal other road users in a sudden hazard situation.
