Selected complaints filed with NHTSA by 2005 Ford Ranger owners, lightly cleaned up (personal details are redacted by NHTSA).
On May 6,2005 our truck just died, towed to dealership and was told the inertia needed to be reset. The switch was sensitive and went off. Usually inertia switches are to prevent fuel from getting to the engine when involved in an accident. Our truck was not involved in an accident and just died. The dealer just reset the switch. On June 28 our truck died while driving. Dealership decided to put a new inertia switch in. On August 29, 2005 our inertia switch kept switching off. Now we have a history of this problem according to the dealerships paperwork. Waited 3 days until July 1, 2005 for a new inertia switch. Replaced switch. On August 23,2005 inertia switch kept turning off again! Furious my wife and I called the manager 10 minutes before closing and asked where the location of the switch is so we could turn our truck on again. …
The fuel inertia switch would malfunction for no reason. The car would just die, losing all power (many times happening at 65 MPH on freeway). It happened at least 15 different times. The "reset" button would have to be used to get vehicle started again. Eventually, the component "melted," and had to be replaced. I was told at the dealership not to let the fuel level get lower than 1/4 tank, to prevent this from happening again. Very dangerous issue, which Ford is aware of< but does nothing!
Tl* the contact owns a 2005 Ford Ranger. The contact stated that while driving at approximately 60 MPH, the vehicle stalled without warning. The vehicle able to be restarted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 127,000.
I had the air bags replaced, after new airbags were installed. Air bag warning light was flashing, code 27, which means passenger air bag bypass module # f81b-14bz68-ad. Module had a bad indicator lamp which in turns disables the entire air bag system. So in my opinion Ford should repair this so that I can have air bags to protect me. With this lamp not fixed I have no air bags, so the recall was useless. I need this fixed and think it should be considered a safety issue along with the air bag recall. I spoke to Ford and they informed me that it was or maybe is an issue, no commitment there. I cannot afford the inspection costs but you tube gave me all the information I need to know, the $89 for inspection and $125. For parts and installation are way out of my budget. This is a safety matter that needs to be addressed. Yes this is a constant condition to the Ford Ranger as it sites now. …
Fuel shut off switch - the wire harness connecting to the fuel shut off switch are melted. Ford replaced one of these switches during my warranty period and since then I have replaced this switch twice. I now notice that the harness connected to this switch has wires that are melted. This switch has activated numerous times while I have been driving and when this happens the vehicle fuel is interrupted and vehicle stalls. I have had this happen on interstate 4 and on various other roads. I find it hard to believe that my vehicle is the only one this happens to. I recently picked up a new switch which has been revamped with an additional wiring harness and a new connection bracket. The problem is that the old harness that this will be attached to has bare wires exposed with no insulation covering them. I am concerned that this constitutes a fire hazard. …
I was driving 65mph on the freeway (which was smooth) and my inertia switch went out. This shut off my power steering, my power brakes and I was almost killed by a semi truck because of this. It happened 10 times today, usually when coming to a stop. This has happened multiple times, and Ford has not yet issued a recall. About two weeks ago, the same thing happened (on the freeway), and once again almost caused an accident. They have already tried fixing this before and it continues to occur. I have read multiple instances of this occurring and believe this is an extremely dangerous defect, and almost cost me my life. I have a 2005 Ford Ranger. Thank you for reading my problem, I am very disturbed by this and hope Ford will fix this.
Two times in 2 days I was driving when the vehicle suddenly stalled/shutoff. Fortunately both times I was able to pull over out of traffic. It felt like my pedal went dead, I lost my power steering as well. Since I was able to connect to the internet through my phone I was able to search "Ford Ranger suddenly dies while driving." an overwhelming amount of results indicated to reset my inertia fuel shutoff switch. I found it, reset it and the truck started again. After the second time this happened I researched Ford Ranger recalls, only to find this was not one of them. I feel very apprehensive about driving my truck, not knowing why it suddenly decides to trip the fuel shutoff switch. This is extremely dangerous and it needs to be recalled.
Inertia switch tripped in 2008 while parked!? Walked home, looked up on internet, found out how to reset. February 2010 the inertia switch tripped again while coasting down smooth road. Pulled over and reset switch. Daughter reports inertia switch tripped a couple of weeks later, fortunately I told her how to reset it. This could be very dangerous and life-threatening, especially if it happened on a crowded freeway! I feel that Ford knows this is a problem, have created a relocation kit. For a hundred bucks! I feel Ford should pay for it. I have only 7K miles on this truck, in five years!
My 19 year old son owns a 2005 Ford Ranger we purchased through a dealer last year. For the last month or so he had to reset the fuel pump inertia switch to get the vehicle started again. This is very dangerous since one time he was on the expressway going 65 and the truck turned off on him. It's happened to him about 5 times and now he is afraid to drive it. Don't know if the inertia switch is bad or if something else is causing this. I hate to take it to the dealer since they tend to throw parts at it and not fix the problem. I think this is so dangerous it should be recalled by the Ford dealer.
Tl* the contact owns a 2005 Ford Ranger. While driving approximately 35 MPH, the vehicle stopped in the middle of traffic without warning. The vehicle was coasted to the contact's residence and the contact replaced the fuel filter. The failure recurred and the contact replaced the fuel pump. The failure recurred a third time and the vehicle was taken to an unknown independent mechanic who diagnosed and replaced the inertia switch. The dealer was not contacted. The manufacturer was made aware of the failure and did not assist. The failure mileage was not provided.
