problem #5

F-150 XLT 3.2L V6

  • Automatic transmission
  • 40,000 miles

Tailgate wouldn’t open due to malfunctioning lock. Other “glitches” in electrical system noted, such as locks on doors being finicky and radio going in and out. Rodents had chewed several spots on wiring harness.

F-150 XLT 3.2L V6

  • Automatic transmission
  • 42,000 miles

Second occurrence of rats chewing wiring. My previous vehicle (Jeep) NEVER had this happen and was kept in the SAME EXACT spot under my carport. My mechanic says it’s the soy-based wiring used by Ford that the rats just love. And, to make matters worse, because of the parts shortage my truck is still waiting to be fixed over a month later. So I’m paying a $700 a month note and $150 a month insurance and don’t even have a vehicle to drive!!!

wires chewed by rodents

Rodent damage due to Ford's design and use of soy material in the wiring. Ford would not cover these damages under their warranty. There is a path way under the intake manifold and the engine block so a rodent can enter unimpeded to the harness wiring that control the fuel injectors. Ford was too cheap to simply cap or cover this pathway or use wiring with plastic coating. Yet I'm stuck paying for Ford's design errors and material problems. This truck is only one year old with less than 7000 miles.

F-150 XLT 3.2L

  • Automatic transmission
  • 6,400 miles

Knock sensor code - P0330 knock sensor. The dealership said it was rat chewed... two weeks late chewed again. I was told the wire wrap knock sensor harness is rat chewed again with bottom 4 inches missing this time. This tells me that Ford know of their flavoured wiring and their solution is to wrap harness in rat chew tape. This tells me they know they have a problem but will not warranty this. Truck is only 7 months old.

Anybody feel this should be a class action lawsuit?

F-150 Lariat 3.5L

  • Automatic transmission
  • 4,236 miles

Rodents got up into the engine in my brand new F-150 and chewed through the Nox sensor wire. Warranty and extended warranty didn't cover it so I am out of pocket. I can't believe a pickup truck which is parked outside is susceptible to rodent damage.
