The 1990 Nissan Van has 4 recalls, all centered on engine compartment fire risks: leaking power steering fluid and deteriorating coolant hoses can both allow flammable fluid to contact hot engine surfaces and ignite.
The coolant hose issue has a longer history on this vehicle. The original recall addressed hoses that deteriorate at the clamp connections and spray coolant onto surrounding components, causing the cooling system to overheat rapidly if fluid levels drop. A follow-up recall later found that some of those repairs were not performed correctly, and engine fires continued to occur on vans that had already been through the remedy. There is also a broader concern about other engine compartment components that can fail from prolonged heat exposure and trigger a fire, though the specific part involved in that filing was not fully identified at the time of the recall.
