Selected complaints filed with NHTSA by 2006 Ford F-150 owners, lightly cleaned up (personal details are redacted by NHTSA).
Odometer Fraud. The contact sold a 2006 Ford F-150. The contact stated that the vehicle was sold with approximately 212,000 miles but later discovered that the buyer had relisted the vehicle for sale with an advertised mileage of 135,713. The vehicle was a private sale. Local authorities had been notified.
while in drive, accelerating to highway speeds or cruising around 30 mph it will downshift and jump to about 4000 PMS's and not shift up into 3rd gear. It blown 1 engine and I have replaced the transmissions, taken it to a Ford dealership and they weren't able to help me. I've replaced the ECM and anti-theft modal also and the symptoms still persist. i am i in for over 11K for the new engine and transmission, and another $100 on the ECM and anti-theft modal plus the shop charges. The truck has under 190,000 miles before any of this started. I am the 2nd owner an had for less than 3k miles before any of the problems started. Now I see the 2015-2017 F-150s are having the same problems getting recalled. is there anything involving the earlier Triton's engines?
There is a very common problem with the brake light always being on due to a short circuit in the cluster, many owners have reported this problem for several manufacturing years, the brake light is always on even though there is no problem with the brakes. This creates a great hazard because if you do have a brake problem since the light is always on you will never know, and you may be in a fatal vehicle accident. Ford motor company should replace or repair all clusters that have this problem.I just purchased this vehicle with this very common problem. Your inspector can google it and will find this is indeed a very common problem.
Morning of July 23,2015, I was driving about 25 mpr speed when number three spark plug blow out of the cylanderhead on my f-150 triton v8. Took it to the local machanic shop walton's. Three hours later, walton's had to replace and resleeve number three cylanderhead and replaced electrical sparkplug wire, plus replaced all eight spark plugs. All at a cost of $543.00. Not only this happened to me but walton's stated that I was the 10th person this week this has happened too. I presented the part to my local Ford dealership where we bought the truck (hall's Ford motor company) brand new in 2006 and paid cash to the sum of $30,000.00. I asked them if they know of this problem with triton v8's. They stated they did but no know recalls and they too had several repairs come in for the same thing in the pass week. …
In June 2015, the air bag light in my Ford f150 illuminated, indicating a problem. I took my vehicle to a Ford dealership. They told me that the deployable restraint system, specifically the pretensioner, had malfunctioned and possibly would fail to function as intended in the event of a crash. The service technician indicated that the restraint system is connected to my air bags, which might fail to work in a crash, increasing the risk of injury. After paying the diagnostic fee, I was given a repair estimate of an additional $392.21. Not wanting to risk injury in the event of a crash, I had the pretensioner replaced. The buckle pretensioner is a critical safety device that should never fail under normal use. My vehicle has never been in an accident. …
My truck caught on fire yesterday. Due to a heat shield missing over passenger side catalytic converter caused the plastic grommets that hold the sound barrier material on the floorboard to drop and hang on top of the catalytic converter until the material caught on fire. My insurance company is still investigating how the catalytic converter heat shield was missing. Less than a month after I bought the truck and it was used, they had to do service work on it because I purchased the truck with a broken front coil spring and the transmission dipstick tube had rotted. Even though the truck was missing a heat shield, I believe there should be any kind of flammable material near the catalytic converter just in case a heat shield happens to rot and fall off or for any reason the heat shield is missing .the fire traveled through the material almost to the top of my engine. …
Spark plugs on the 5.3 liter engine when replaced break--in return the book said pull engine and pull heads to replace spark plugs. The law suit filled Ford admits to bad decision on spark plugs and will reimburse some of the cost. The cost is very high--the book and Ford's shop said the engine needs to be pulled to pull the heads to replace the spark plugs. There was never any software updates, and now the vehicle requires them. The error in the cluster software recall was suppose to be repaired and I read from the experts all software should have been upgraded with the cluster error. There are 42 p.m. Ford and nhsta knew or knows about on my vehicle and nothing has been done, I am a 100% dav and my vehicle has been broken down. The 2006 harley davidson f-150 that cost so much with it's on board computer system does not work. …
My 2006 f150 Ford lariat. It started with the front map light are some light not sure what it's called. It would come on by itself just sitting still with engine off. And no one in the truck. It would do this all hours of day and night. Then the door jar light came on going down the hwy. And would not go off. We stop to check all does and they all was shut. It stays on and want go off. Then with all that going on all my power windows stop working. They was working fine but when the dime light problem. And the door a jar light on when you get in the truck and turn key on. I have talk to people that own a Ford and most all Ford's have had this problem. I also have googled these problems and a lot of people have had the same problems. But it hasn't been any recall on these problems. It really needs to be a recall for these problems on Ford's. It's a electrical problem.
Interior lights do not light up on opening the door. Additionally, upon starting the engine, the electrical panel blinks, fizzles, demands reset, which doesn't reset, and eventually corrects itself sometimes after 15 minutes of blinking. Additionally, the high beams implement and then you cannot make the high beams turn off. May all be related but, seems like 3 separate issues, all seem to be related to the electrical panel. Blinking begins while stationary upon starting truck and continues while in motion, indicates problem with everything electrical including speedometer and states auto locks fail, along with blinking failure of all systems stating reset but pushing reset does not appear to fix anything.....only time fixes it.
Vehicle started losing power and unable to run correctly. Took to garage and fuel pump drive module was rusted with circuits being exposed to the salt and moisture elements where there was a large hole in back of unit. New one was installed with spacers to help prevent salt and moisture from collecting where back of module mounts onto axle bracket. Vehicle ran better but also had to install new coil due to a cylinder missing. Runs OK with work that was performed. Module should not have been installed against the bracket so salt and moisture could collect and rust it so badly and cause it to fail. Ford should pay for this repair due to the way in which the module was installed so it would rust so badly.
