Owners of the 1986 Ford Aerostar most often describe fires or smoke from the engine area or near the dash, with some reported while the van was parked. Other complaints describe stalling, loss of drive power, transmission problems, and fuel tank or filler pipe leaks. The fire reports in this sample do not list mileage, so the pattern cannot be tied to mileage.

1. 1
   Electrical system

   Fire or smoke from the engine area or dash

   • 29 complaints (55%)
   • median 300,000 mi at 30.7 yrs old (1 states mileage, few)
   • 22 mention a crash, fire or injury
   • filed 1995–2017

   Owners describe smoke, sparks, or flames from under the hood or near the dash. Some complaints suggest an electrical cause, such as a hot ignition key switch, while others say the cause was never determined. A complaint says the van had been in the shop repeatedly before it burned under the hood. Mileage is not listed for any of these reports, and most describe a fire that began while the van was parked or idling.

   What to check: Inspect the wiring, fuel lines, and ignition area under the hood for heat damage, melted insulation, or leaks, and ask whether any fire or wiring repairs have been documented. Ask the seller whether the van has any open recall work.

   Transmission and drivetrain

   Stalling, power loss, or transmission faults

   • 9 complaints (17%)
   • typically at 12.2 yrs old
   • 1 mention a crash, fire or injury
   • filed 1995–2001

   Owners describe a transmission that failed again after an earlier rebuild while the van was being driven. Another complaint describes the van losing power when the gas pedal was pressed, as if it were in neutral, and a dealer who said the van had the wrong transmission. A complaint describes stalling on start-up that cleared once the engine warmed up. While the van was parked, the engine accelerated on its own after a shift into reverse, and the van struck a house across the street. Mileage is not listed for these reports, and most describe problems while driving or starting the engine.

   What to check: Ask for the transmission service history, including any rebuild, and test the van from a cold start through shifts into drive and reverse. Ask the seller whether the engine has ever stalled on start-up or lost power under throttle.

Buying note.

Ask whether any fire or fuel leak repairs have been documented, since several complaints describe those problems.
