While driving this vehicle, the spark plugs have blown out of the engine six times requiring six different tows home. The vehicle is unreliable for me (disabled, single mom) who has to take my daughter and I to doctors appointments. I feel unsafe and it is not safe for my daughter, but I can't afford to trade or get another vehicle. I think ford should come good for this defect. *Tr

2003 Ford explorer, while driving through town I started to slow down for a group of kids waiting to use a cross walk when the explorer shut down & lost all power to control brakes and steering almost hitting the kids.. I have taken to a shop & was told they could not duplicate the issues I have been having for 5 years. The reason I am now reporting this is because the close call I just had with the cross walk. This problem starts after about 5 or 10 minutes of run time then clears up not returning until next run or some time later...

Took vehicle in fluid changes, complete check, and to investigate a leak under vehicle. After "complete" check said they found bad serpentine belt, air filter and but nothing valve cover gaskets as cause of leak. Cost to repair gaskets over $1000. While doing repair they called again and said they found that the rear timing cartridge was broken and pieces of it missing. Told me that bolt was wore half way through as timing chaining was rubbing it. Said if it breaks before repair engine will "blow" and need to be...

replaced. Told me it would costs over $2,500 to replace this cartridge. Total cost was now over $4,000. I asked why part was bad when engine only had 84,000 miles and why this wasn't found with the "complete" check. Mechanic stated only saw it because he had things apart to fix valve cover gaskets. Told me it was a plastic part and even with low mileage the plastic deteriorates with time. Said part only designed to last 100,000 miles. If I am to believe this ford mechanic, ford uses a plastic part in a crucial part of the engine (timing) and if that part fails the engine will "blow". And they cannot know the part is bad unless they have the engine apart for other major repairs. So if the valve cover gaskets were not leaking the issue would have been undetected by the ford maintenance "complete" check up. In addition ford has not issued a warning that this engine will possibly "blow" after only 100,000 miles if this part not replaced by a $2,500.00 - $3,000.00 Repair. Ford should pay for this repair. They design a vehicle this way with no warning to the buyers/owners. If I am to believe the ford mechanic there is no way to really know you may have a problem. How are we to protect ourselves? My friend showed me this site and did some searching on other blogs/sites dealing with vehicle issues. There are numerous cases of this unacceptable issue. *Tr

As I have been driving like I normally do the o/d light came on blinking. Then I pressed the button for it nothing happened. I continued with my daily routine and the light came on and off. And continued to blink. Then all of the sudden I would step on the gas but it would not give me anymore than 15mph. When I came to a traffic light my car did not want to go anymore so I had to pull over on the side of the road. It didn't want to continue going. Then after the third try it gave me more gas to drive normal not...

even a minute after it did it again. I was afraid yo get hit by traffic and since I had my three toddlers I was scared. I pulled into a shopping center and called my dad. And also a mechanic. It needs a new transmission when that vehicle has had all its needs. I cannot afford it and its upsetting seeing all the complaints on carcomplaints.Com about it knowing I am not the only one with this problem. This is a defect and it should be recalled. *Tr

Vehicle died upon turning once again. This is becoming more frequent, as it has happened twice now in the last week. Seems to occur after highway speed, then slowing for a turn (tipically a right hand turn). I consider myself quite mechanically inclined and I am baffled. I also own an obdii scanner and no codes come up!! This is the second time I have filed a complaint, and would like some answers. Very dangerous issue in my opinion!! I will also be posting this on other websites to raise awareness, and hopefully get some results!! This is unacceptable. *Tr

My truck just went out of warranty by 5,000 miles and I was driving and hit a bump and my #3 spark plug blew out of the engine. Scared me to death because it sounded like a gun. I had just turned off a red light so I had no speed at all. $500 To put a helio coil in it. Then I hit 170,000 and another one blew out while my family and I were in the mountains and we had to limp home. Told by the mechanic the truck could have started fire. I had every single service by ford until the first one blew. Never ever...

heard of this happening until I searched it on the internet. What if I had my hood open changing the air filter and or other part and one of them had blown? Could kill anyone. How is that safe. And the fact that your in the middle of no where with no cell coverage and you have to drive a ticking time bomb. Please hold ford accountable for design flaw. I take care of my ford explorer, after all it cost 36k new and I want to get my money out of it. They are supposed to be built to last with regular maintenance. It has been a great suv with the exception of the spark plug issue. The only reason I still have it is because I love it. (Last number on vin is 5 but it wouldn't let me enter it.) *Tr

The car was idling rough and the "service engine" light kept coming on, even after I had the auto repair shop (pep boys) check and fix things. They advised me to go to the ford dealer, and said it may be the timing chain. Future ford ran diagnostic, said it may be timing chain but have to open engine to verify. Estimate for repairs $1500 to open engine and $2500 to fix). Did not have work done yet.

There is an oily smell. At stop light when idling, the idle is slow and a loud knocking sound - idle sounds like car is about to shut off. The normal idle sound for the car is smooth and like a soft hum. Called ford to see if there is a recall for this problem, as there are many complaints similar to mine that are listed on the ford website about several years of the ford explorer. Mileage now is 150,000 miles. Ford said there is no recall, but keep receipts for work done in case of one in the future.

down the highway and the light turns back on and it will not shift and is straining shift. I took it in to jiffy lube to go ahead and get another oil change and let them check the transmission fluid and they said that they could not access it to check the fluid-they suggested a transmission flush at $200-why can't they access it? Wouldn't a dip stick save a lot of trouble? As I look at all the complaints about the transmission troubles in the explorers, I am very shocked. Please can you help me out here as I cannot afford high maintenance bills that would be charged through a dealer. Just tell me if there is a simple solution to fixing it so that my brother may repair it and get it back on the road. One response is as such: after talking to 2 ford reps today, and turned down flat for help, I have decide its now a quest.... Ford stated they didn't have enough complaints for the nhtsa to open up an investigation to possibly order a recall...... Soooo, for all those that have issues, call ford and also make a complaint on the nhtsa site www.Nhtsa.Gov or call them at 1-800-424-9393. My family is a ford family and we currently have 5 fords in our household, a mustang, ford f150, ford focus, expedition, and the explorer that is having issues. This isn't including extended family.

Was driving the vehicle when I noticed smoke coming out from under the hood. I pulled over as quick as possible into a strip mall parking lot. Before I got out flames were coming out of the engine compartment. I ran into a store and got a fire extinguisher to try and put out the fire. I failed, as the whole front of the explorer was in flames as well as the interior. The vehicle is a total loss. The fire department put it out. I had the vehicle for 7 weeks. The used dealer will not take any responsibility. Should they? I purchased the vehicle on mar. 3,2014 At oc auto expo in westminster, ca. *Tr

The thermostat housing unit was leaking. The over drive warning light illuminated prior to the failure. The contact was forced to drive the vehicle onto the emergency lane. The vehicle would drive forward or in reverse and it also failed to function in first gear. The vehicle would only move forward in second gear. The contact was able to continue driving five miles in second gear to his residence at 35 mph. After the failure occurred the contact also added anti freeze to the vehicle. The transmission also failed shortly after the failure occurred and he was unable to drive in reverse gear. The mechanic stated that the bands in the transmission may have caused the failure to occur. A local mechanic replaced the thermostat housing unit which has three hoses attached to it. Ford was currently checking the transmission to determine the cause of failure. The failure mileage was 96,600. The current mileage was 96,620.

I have been having issues with the cruise control on my explorer. It works fine for several months and then occasionally it will not engage. Most times if it will not engage, the dashboard light does not show up, but since last week the light has come on, but the cruise control has not engaged. Since this has been an ongoing issue and seems to resolve on its own, I continue to try it occasionally. I tried to set it last friday while I was going approximately 40 mph. It did engage, but then began to slowly...

accelerate. I tried pushing the button that should reduce the speed, but it continued accelerating, so I kicked the brake pedal to disengage. I have tried it 3 additional times and each time it accelerates. The last time I tried it, yesterday afternoon, the speed was picking up incredibly quickly. It felt like I had just floored the accelerator. I was able to kick the cruise control off with the brake pedal though but am now concerned that this may happen when the cruise is not engaged. *Tr

Consumer writes in regards to humming/whining noise in the rear end of vehicle and a frequent leak in the differential. *Smd the consumer stated several components such as the ring an pinion, bearings, seals and gear and pinion were all replaced. However, the issue remained unresolved. Also, the rear hatch was cracked. When the consumer inquired about a replacement and its cost, the dealer advised against the replacement/repair as the new hatches had the same problem. The vehicle overheated and had to be towed to the dealer. A diagnosis revealed a damaged thermostat housing.

While driving my vehicle on sunday, while driving my vehicle stalled in the road. The truck felt as if it was trying to pull a hill. This was very scarey for me and my children because if someone was coming behind us or if I was turning into the flow of traffic this could have been a terrible accident. Afterwards the vehicle couldn't go over 30 mph without shifting out. This is very dangerous and ford should recall this immediately before someone is killed. *Tr
