The 1990 Volkswagen Cabriolet has 3 recalls, the most serious being a fuel tank that can crack near a seam weld and leak gasoline, creating a fire risk if a source of ignition is present.
A separate speed control concern involves a panel in the engine compartment that can bend if someone leans on it during routine maintenance like checking fluids. If the panel deforms enough, it can press against the accelerator linkage and prevent it from moving freely, which may cause unintended acceleration. There is also an airbag wiring concern: the harness wire running through the dashboard crossmember may have been routed through the wrong opening and can become pinched and worn between two panels over time. If the wire degrades enough, the airbag system can stop functioning and may not deploy in a crash.
