The 1999 Volkswagen Golf has 4 recalls, the most serious being two separate fire risks: a sound-absorbing mat inside the B-pillar trim that can ignite during a crash, and a fuel pump supply nipple that can crack and leak gasoline near an ignition source.
The mat issue occurs because the material sits close to the seatbelt pretensioner, which releases hot exhaust gas when it fires in a severe front or side collision. If the mat was damaged or poorly seated during assembly, that gas can set it alight inside the cabin. The fuel system concern is separate: on vehicles with double-layer fuel tanks, tension on the fuel supply line can crack the pump's outlet nipple, allowing raw gasoline to drip out where it can ignite. On the electrical side, a brake light switch that was installed incorrectly can cause the brake lights to stay on constantly or go dark entirely, meaning drivers behind the car get no warning when the brakes are being applied. There is also a label concern specific to vehicles with the 2.8L VR6 engine: the tire inflation sticker recommends a cold pressure that is slightly too low for the 205/50 R15 tire size, and running tires at that lower pressure over time can affect handling and stability.
