The 1998 Volkswagen Beetle has 4 recalls, the most serious being engine compartment wiring that chafes against the battery tray over time, which can cause the fuel pump to fail or start a fire under the hood.
The wiring damage can produce two distinct problems: the fuel pump may cut out unexpectedly, stalling the vehicle without warning while driving, or the frayed wiring can ignite a fire in the engine compartment. The other two recalls cover the same brake lamp switch defect and are treated here as one issue. The brake lamp switch can malfunction in either direction: the brake lights may stop working entirely, meaning following drivers get no warning when you slow down, or the lights may stay on constantly even with the vehicle parked, draining the battery over time.
