Tl* the contact owns a 2006 ford f-150. The contact stated that while braking to a stop, the vehicle suddenly stalled. The vehicle was taken to a private mechanic where the failure could not be replicated. The manufacturer was not contacted. The failure mileage was 127,000. The VIN was unavailable.
Tl* the contact owns a 2006 ford f-150. The contact stated that while traveling 50 MPH, there was a loud beep and the safe mode signal illuminated then the vehicle stalled. The vehicle was merged to the shoulder and after waiting for about 15 minutes, the vehicle was able to be restarted. The vehicle had not been inspected. The failure and current mileages were 50,100.
While turning truck started to emit noises, sounded like an exhaust problem, manifold etc. No service engine light on and all gauges were normal. Then while driving, as truck shifted down to overdrive, noise returned, loss of power, but again no service engine light, gauges all normal. Took vehicle to dealer, have been told, engine needs to be replaced,(81,250 miles/130,000km) for a meager $6000. Vehicle has been dealer maintained since new, oil changed every 3125, miles/5000km (by dealer) still no service engine light, gauges still reading normal. Manufacturer will do nothing. Looking for lawyer who would like to start class action suit against manufacturer, considering all the issues I have found on the 2006 f150 v8 triton since starting research yesterday, there are a lot of us that ford is not willing to assist.
Tl* the contact owns a 2006 ford f-150. The contact stated that the check engine warning light was illuminated. The failure recurred five times. The vehicle was taken to the dealer for diagnostic testing. The technician advised the contact that the coil packs would need to be replaced. The vehicle was repaired. The VIN was not available. The approximate failure mileage was 6,000.
While approaching an intersection, about to make a right at the light, (I was driving about 20mph) on 12/24/12 (with my two children and husband in the truck) the vehicle beeps and it displays "engine safe mode...low oil pressure" then the power steering cuts off and the whole vehicle shut down! I am frantic at this point because I have no clue what is going on! I was in the middle of traffic and had to cut the car off and crank it up again. Luckily I didn't get rear ended or in an accident. That same day I went and got my oil change because it was over due. Well on 1/4/13 the same thing happens as I am turning into the parking lot of mcdonald's. I get the same error message as before, the steering wheel locks up, and truck cuts off! This so extremely dangerous. I looked this issue up online and see that it appears to be a common issue with the 2006 f-150 and the expedition. My bother-in-law, who also has a similar f-150 to ours, said the same thing has happened to him twice.
According to the model year ford f150 maintenance manual, spark plugs are to be changed every 100,000mi. Just prior to this mileage for removal and replacement of the spark plugs the engine started to develop a misfire. Ford has recognized the problem with the spark plugs and the difficulty to remove them. This known maintenance issue LED ford to provide a tsb on the issue. This misfire has almost caused me to stall several times while towing a 7,000lb boat. This is dangerous and creates a safety issue for myself and the motorists around me. I express concern that ford should be replacing these defective plugs with updated designs before tragedies start to happen. This engine/spark plug design entered service in 2004 and vehicles, like mine, will begin to experience serious safety related incidents if it is not addressed.
I was driving home and slowed down to 15 miles per hr to make a left hand turn and heard a big bang I did not know what happened at the moment I continued to proceed on and the noise was loud like an exhaust leak but to come find out the next two days on thinking what to do I pulled off the #4 plug it was out of the motor already it actually blew out of the engine. What are my rights if any?
On july 1, 2012, my 2006 ford f-150 super crew truck caught on fire while sitting in my driveway. The truck had been sitting untouched for a week when it caught on fire without any explanation. Fire investigators were unable to determine the cause of the fire because the truck was approximately 90% burned.
I had a fuel injector fail that completely ruined the engine at 71k miles. I had to have it replaced. I was very surprised to see that my problem was exactly like the ford 2005 customer satisfaction program 07m08 problem. My truck was built in 2005, but titled as a 2006. I have talked and wrote to ford but they would not help me. I told them I still have the failed injector and they wouldn't even look at it to see if it was one of the defective parts that spurred the 07m08 program. I believe ford needs to expand the customer satisfaction program 07m08 to include 2006 models. I would love for the federal safety agency to pressure ford to revisit this issue. This was hard for me because I still have the injector that failed. I keep it as a reminder of the $8,000 I had to spend on a new engine. I believe the federal safety agency should pressure ford to admit which injectors were an issue so people like me have leverage to fight giants like ford that in this case screwed their customer.

Truck ran rough with have smoke from exhaust. Took truck in at 41,000 to fix a bad coil assembly, then at 99,000 to fix a bad coil assembly, injector and o2 sensor. At 111,000 miles two more injectors went bad causing two rods to be bent along with another bad o2 sensor. Same problem as the 2005 ford that had a recall, but not the 2006. Total estimate to fix truck $7500 plus tax! Ford knows about problem but wont recall.

To start out, it should not cost $1249.00 to change one spark plug... Due to ford's design flaw on their motor craft spark plugs which causes th em to break extremely easy, I am being charged to tear down my entire engine to retreive one spark plug!!! This is ford's fault and I feel they should be held liable for the cost of repair. I have been told by several mechanics that ford designed their motor craft plugs to break!! Ford is also the only one who can fix the problem. It was not until I paid over $400.00 to change 2 coil packs that I was hit with this price. This f-150 woulonly do 30-35 MPH on the interstate highway...I could have been killed if I was hit from behind!! These spark plugs should be recalled and I should be reimbursed! My truck is still at the ford dealership after a week...I already paid $126.00 for my motor craft parts by cash even before taking my truck to them. This is not right on the part of ford to design a vehicle like that. Please investigate this defect problem so others are not charged like I am being charged. Please recall these spark plugs !!!!

Spark plugs are snapping off because of heat in the aluminum head.
Over a period of 3 months, I was experiencing a rough idle, loss of power when accelerating on flat surfaces as well as climbing hills. I took it to a mechanic who said it was 2 bad coil packs. They fixed it and 2 weeks later same incident occurred and they replaced it. During this time, I could always smell the odor of gasoline. After the large expense I was assuming, I called the ford dealer where I bought my 2006 f-150 lariat. The service manager of 22 years apparently never heard of the coil pack going bad along with the spark plugs breaking due to this. After arguing for a week with them, they finally agreed to pay for the replacement of all 8 coil packs. During this sequence, a coil pack was going bad weekly and I had to continually have it in the shop. Ford needs to address this issue and as I can see, there are a lot of these issues out there and ford continues to disregard a recall. There is a definite safety issue as gasoline will emit from the crack in the coil pack and could cause a fire under the right condition. This is unacceptable.
I have a 2006 ford f-150 and upon removing the spark plugs at 60,00 miles, which aren't due to be done until 100,00 miles, the spark plugs broke off in the head. I have been a certified mechanic in the past so I know how to remove spark plugs. Ford should be issuing a recall on this problem. The problem is discussed a lot on internet sites and well documented to be a problem.
2006 ford f150 with 39,000 miles acting funny. Took it to garage and was catalytic converter. Stated they wouldn't cover it because I drove to garage.
