I bought it with @ 10,000 miles on the odometer. I have had nothing but hell with it from day one. First off I put two new front rotors and brake pads all the way around and both idler pulleys were squealing so I replaced them . Then at @ 19,000 miles I had to replace both cvj half shafts . Now at 45,000 miles they are both shot again the cvj half shafts are . On the first of January this year I was driving down the road and the vehicle was running good suddenly it began to cut out and the power fell off on its face. I purchased an obd11 code reader to try and diagnose the problem. It tells me that random misfire detected and that cylinders 5 6 7 8 are misfiring . Let me just say that 4 months later after going thru everything from the plugs wires injectors and replacing the fuel pump module assembly it is still not running and I'm at my end of trying to get the peice of shit running. There is no way in hell at 45,000 miles on the vehicle that I should be having all the hell with the vehicle. I live in new mexico and we do have a lemon law here. I am beyond the shadow of a doubt sure that this truck is a damn lemon.
Tl the contact owns a 2012 Ford F-150. The contact stated that the vehicle lacked engine power when the vehicle was stationary. An independent mechanic inspected the vehicle and found a p0016 error code, which indicated that the timing belt was loose and needed to be replaced. The contact visited the dealer (medford motors, inc, 105 wisconsin Ave, medford, WI 54451, (715) 748-3700) and the failure was confirmed. The dealer stated that the repair would cost over $3,000 without a recall available. The manufacturer was notified and confirmed what the dealer stated. The failure mileage was 77,000.
My 2012 f150 ecoboost 3. 5 studders severely, hesitates, and will not accelerate when trying to pass on the highway. The dealer has bulletins addressing this. I have been told multiple repairs that now are not under warranty including cac cooler deflector, spark plugs, catalytic converter, cam phasers, timing belt, and many others. The truck started this problem and may now require the turbos be replaced. This is a very common problem with this motor and Ford is well aware of the issue. This defect should be covered by Ford.
Already had timing belt replaced at 84,000 miles. Now at 85,600 miles I was on ramp merging onto hwy. When a blinking engine light came on, loss of power, and truck shook like crazy. I felt like it was a poltergeist. Took next exit off and came to a complete stop. Engine light went off and truck acted normally again. Damp conditions. Not liking all the complaints I have read and certainly not liking the sporatic unknown. I think I'll be trading this $50,000 lariat in for something else. Ford needs to react, that was a scary situation on the freeway with trucks bearing down on me.
Leaving so cal on I-15 in dry conditions cruise control set at 70. While climbing the cahon pass the truck felt like the engine died. The cruise control shut off and the vehicle shook and went into the limp home mode. It was early and traffic was light so I was able to pull to the side of the road. When I came to a stop the ck engine light, a wrench symbol along with the stability control symbol were all illuminated. I shut the truck off, got out and did a vehicle walk around nothing obvious on the outside so I popped the hood checked the fluids, belts etc. And everything looked fine. Got back in the truck started it and all the lights had cleared. Drove the remaining 300 miles home without any further problems. Took it to my local Ford dealer and had it checked, they couldn't find anything wrong Friday 22 Nov 2013 wife and I headed back to so cal it was raining for the first 200 miles then cleared up. I set the cruise at 75 and less than 50 miles later the truck did the same thing, same exact symptoms and dash symbols, I was in the right lane at the time so it wasn't a problem getting in the emergency lane. Stopped the truck shut it down and ran the same checks that I'd done previously, same result symbols cleared and the truck ran fine. 100 miles later it did it again in victorville CA. This time I was in the center lane and almost got rear ended by another vehicle. Worked my way to the right lane and luckily there was and exit. Found a place to stop and shut the engine off, didn't bother to check anything just left it off for about a minute then started it and it ran fine although the engine light remained on. Found a Ford dealer and tried to get them to check it out for me, but they said they couldn't get to it for at least 3 hours. Wife and I decided we would turn around and head for home, no further problems on the trip home.
