At this point all 4 door locks/latches are messed up. Both driver &passenger back doors won't open from outside or inside. Driver &passenger front doors won't open from outside unless open from inside first. Key won't unlock doors. Back glass on hatch door won't open. Back wiper broken. Back hatch wouldn't open untill I paid to have it fixed. I contacted the manufacturer they said my truck not on recall list & wanted me to pay to fix it. My truck has same issues as the ones being recalled. How do they determine which ones to recall?

Seats: front assembly: recliner
- What is wrong
- On certain sport utility vehicles equipped with high back seats, the upper bolt on the driver's side high back seat, that attaches the seat recliner mechanism to the seat back frame, could fracture. If the bolt fractures and does not jam in the seat back frame, the seat back may recline until it makes contact with an object behind the seat, such as the second row seat cushion.
- Risk
- The driver could potentially lose contact with the steering wheel or foot pedals during such an event, increasing the risk of a crash.
- Remedy
- Dealers will replace the driver seat upper bolt with a metal spacer and bolt. In addition, seats with tubular back frames will have the fully threaded lower recliner bolt replaced with a partially threaded bolt. Owner notification began on august 29, 2003. Owners should contact ford at 1‑800‑392‑3673.
Recall number 03V281000 · Recall details
Vehicle speed control
- What is wrong
- Vehicle description: sport utility vehicles equipped with 4.0l sohc engines and still retain the original throttle body (part numbers 97jf-9e926ab or 97jf-9e926-AC). Some of the original throttle bodies installed allowed a gap between the plate and bore to be built too narrow. This reduced clearance allowed the engine deposits normally present in the throttle body to contact or bridge the gap. If the engine deposits bridged the gap between the throttle plate and bore and then hardened, on the initial application of the accelerator pedal after the engine has cooled, the operator would need to apply additional force to the accelerator pedal to break the bridge.
- Risk
- This could result in engine surge when the accelerator pedal breaks free.
- Remedy
- Dealers will replace the original throttle bodies.
Recall number 00V422000 · Recall details
Latches/locks/linkages: hood: latch
- What is wrong
- Vehicle description: sport utility vehicles. The secondary hood latch may corrode at the latch pivot and stick in the open position.
- Risk
- If this occurs and the primary hood latch is either not engaged or is released, a hood fly-up could occur.
- Remedy
- Dealers will install a secondary hood latch with components that are coated prior to assembly for improved latch pivot corrosion protection.
Recall number 99V164000 · Recall details
Vehicle speed control
- What is wrong
- Vehicle description: certain 1997-1999 rhd explorer equipped with 4.0l ohv/sohc engines and cruise control built from may 29, 1996 through march 4, 1999; 1998-1999 explorer/mountaineers equipped with 4.0l ohv/sohc or 5.0l engines or 1998-1999 rangers equipped with 2.5l, 3.0l ffv/efi or 4.0l engines and cruise control built from january 5, 1998 through march 4, 1999; 1998-1999 mustangs equipped with 3.8l, 4.6l 2-valve or 4-valve engines and cruise control built from march 2, 1998 through march 4, 1999; 1999 f250/f350/f450/f550 (over 8,500 lbs.) trucks equipped with 5.4l or 6.8l engines and cruise control built from march 2, 1998 through march 4, 1999; and 1999 f-53 stripped chassis equipped with 5.4l or 6.8l engines and cruise control built from march 2, 1998 through march 4, 1999. A cruise control cable can interfere with the speed control servo pulley and not allow the throttle to return to idle when disengaging the cruise control.
- Risk
- If the cruise control is used and this condition is present, a stuck throttle could result, which could potentially result in a crash.
- Remedy
- Dealers will replace the cruise control cables. At the present time, the replacement cables are not available. Customers are being advised not to use the cruise control system until a replacement can be made.
Recall number 99V062001 · Recall details
Fuel system, gasoline: delivery: hoses, lines/piping, and fittings
- What is wrong
- Vehicle description: multi-purpose passenger vehicles equipped with 4.0l single overhead cam engines. The engine fuel lines can be damaged if the vehicle is jump started and the ground cable is attached to the fuel line bracket that is located near the battery. Since the bracket is not grounded, the stainless steel fuel line braid could act as a ground potentially overheating the ptfe inner liner of the fuel line resulting in damage to the fuel line.
- Risk
- The fuel lines can leak, and in the presence of an ignition source, a fire could potentially result.
- Remedy
- Dealers will install a warning label on the fuel line bracket advising owners not to use it for a jump start ground. Also a revised bolt will be installed in the alternator bracket to provide a convenient jump start ground location.

Defect investigations
Spark plug ejection from cylinder head
On september 6, 2005, odi received a petition requesting that the agency investigate allegations of engine spark plug ejection in certain model year 1997 through 2004 ford vehicles with triton v-8 and v-10 engines.odi received a total of 474 non-duplicative complaints on the subject vehicles where the complainant, or the dealer repairing the vehicle, reported that a spark plug detached from the cylinder and/or ejected from the engine.as of december 8, 2005, odi is not aware of any allegations where the alleged defect resulted in a loss of vehicle control, a crash, an injury, or a fatality in any of the 10,319,810 subject vehicles.in addition, odi is aware of only two incidents where the vehicle stalled without restart.information contained in the odi consumer complaints and obtained from 72 telephone interviews with complainants showed the following:(1) 99% of the complaints were on my 1997 to 2002 subject vehicles.(2) most the complainants reported hearing a loud pop while driving or upon starting up the vehicle followed by a loud, repetitive clicking or popping sound.(3) many of the complainants reported that the popping sound was accompanied by some loss of vehicle power; however, in 99% of the incidents reported, the vehicle did not stall.in the very few incidents where the vehicle did stall, most vehicles could be restarted.(4) only a small percentage of the complainants cited that they smelled gas or a slight burning smell when the incident occurred.(5) in all but a very few incidents, vehicle damage was limited to the engine.in one incident, the complaint reported that the fuel rail was damaged and replaced after one of the spark plugs ejected from the engine; however, the complainant reported that the damage did not result in any type of fuel leak or fire.in another incident, the only incident where a fire was alleged, the complainant reported that no fluid leak was observed, but that a fire resulted after the spark plug had ejected from the engine and he had restarted the vehicle and driven to another location.none of the complainants reported any damage to the vehicle hood.(6) only two complainants reported that they observed what appeared to be some drops of fuel coming from the cylinder where the spark plug had failed or on the spark plug itself; however, each of these complainants reported that there was no smoke or flames as a result of his incident.as the petitioner noted, and odi?s analysis showed, it is possible for a spark plug to detach from the engine cylinder threads in the subject vehicles.however, odi?s analysis of 474 complaints describing such incidents found only a very few alleged any safety-related consequences.none of these showed any evidence of a serious safety consequence.given the large population and relatively long exposure time of the subject vehicles, the complaint analysis indicates that the risk to motor vehicle safety from the alleged defect is very low.in view of the foregoing, it is unlikely that the federal safety agency would issue an order for the notification and remedy of the alleged defect at the conclusion of the investigation requested in the petition.therefore, in view of the need to allocate and prioritize the federal safety agency?s limited resources to best accomplish the agency?s safety mission, the petition is denied.

Engine compartment fires
Ea05-005 is closed with ford?s actions in recalls 05v‑017, 05v‑388, and 06v‑286, recalling approximately 6.7 million vehicles equipped with texas instruments speed control deactivation switches (scds).the brake systems in these recalled vehicles generate a vacuum that can potentially cause the scds to fail and, in certain switch installation orientations, catch fire.ford is also including the entire population of 1998 explorers.ford has informed odi that testing to determine the cause of failures in the 1998 explorers will continue after this investigation is closed.odi believes that the vehicles exhibiting the factors causing scds failure described in this report correlate well with the observed failure rates on these vehicles by model and model year.the closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist in the non-recalled vehicles manufactured with scds that are not included in ford?s recalls.odi will continue to monitor the non-recalled population for incidence of engine compartment fires.the agency reserves the right to take further action if warranted by the circumstances.see attached closing report for details.

What 1998 Mercury Mountaineer owners say
Most recent owner complaints, unedited.
Under my hood started smoking, I popped my hood to find flames under it. I had to get my kids out the truck and put the flames out with and extinguisher. That's when I noticed that my brake fluid reservoir was melted and so were the wires that connect to the cruise control switch. Not I am without a vehicle to get to work and get my children to school.
Drivers seat broken unable to adjust for proper vision via windshield.
One of the braided stainless steel fuel lines that attaches to the engines fuel rail developed a leak. I kept smelling a strong odor of gas, but I could not find out where it was coming from. After two weeks of smelling the gas, I took it to a garage and they showed me the gas squirting from the braided hose going to the engine. I took the vehicle to the ford dealer and showed them the leak. They took the vehicle in their shop and removed the fuel lines. Because of the age of the vehicle, ford does not provide any replacement parts. I was unable to get replacement fuel lines from ford. I checked with "junk yards" all over the country. I had no luck finding replacement fuel lines. Junk yards cut the fuel line when they pull engines. I finally located a company in new castle, de that supplies hydraulic hoses, etc. I took my old fuel lines to them and they removed the fittings and installed them on new stainless steel braided lines. I took the new lines back to the ford dealer and they installed them on my vehicle. They said the new hoses had no leaks. The ford dealer charged me over $400.00 to remove the old hoses and install new hoses. The shop in new castle, de only charged me $40.00 for a pair of new hoses. I'm very lucky I did not have an engine fire. These stainless hoses are used on a lot of ford vehicles. Ford should be required to supply replacement hoses.
Tl* the contact owns a 1998 mercury mountaineer. The contact stated that while driving at 45 MPH, the steering wheel became difficult to maneuver. The failure occurred on several occasions. The vehicle was towed to an independent mechanic where it was diagnosed that the tire rods, wheel bearings, and the tires needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 210,000.
Had a wreck coming down the mountain. Emergency brake didn't work ran into a tree and damaged a mailbox (related vehicle information: model year=1998, make=mountaineer , model=mercury ).
All of a sudden with no warning my interior dome lights, power windows and front and back windshield wipers didn't function. I was driving it started to rain and I could see very well without functioning wipers. I had to pull over to the side of the road. I figure that a fuse might have blown but when I checked all fuses they seem to be ok. I was reviewing a recall for a 1999 mountaineer for a gem problem. Although my vehicle is a 1998, could this problem be similar to the 1999 recall. It appears to have all the similar symptoms . Is it possible that my 1998 mountaineer has a recall for the same problem. Thank you
