F-150 Extended 5.4L Triton Liter

  • Automatic transmission
  • 98,000 miles


Took the car in for another issue that cost me $500.00. While it was there I had him change the oil. Afterwards car started knocking. Went to a local guy that used to work for Ford. He said the engine was done and wouldn't even be worth replacing because this is a issue with these engines. So I could get a decent used engine and at around 80,000 it could happen again. Now car is sitting in the driveway and I still owe money on it and I had to buy another car to get back and forth to work. Now two car payments and two insurance payments!!!!!!!!

F-150 XLT 5.4L

  • Automatic transmission
  • 176,900 miles

I have had issues with this 2008 F150 XLT Crewcab since around 80K miles (I bought this vehicle brand new from a local Ford Dealer). I have had the transmission overhauled and replaced 3 separate times with the same exact symptoms- metal whining sound and shaking.

Most recently (Feb 2017), I took my truck into the local Ford Dealer to have them check on the truck shaking again even though they put a new transmission in on 7/31/17. This time they found that the motor is bad and needs to be replaced at a cost of $8800!! (didn't find that last time they did diagnosis) But these 5.4 liter engines are on back order for 2 quarters! (What does that say?)

Additionally, the diagnostics found that the VCT System was erratic and the root cause to be excessive crankshaft end play causing lack of oil pressure to cylinder heads. I have had this vehicle serviced regularly and changed the oil with 5W20 and filter every 5K miles! I have owned Fords all of my life and this is the worse vehicle I have ever owned! Even my Ford Grenada wasn't this bad!!

If there are any class actions pending I would love to get involved. Never buying another Ford again!

F-150 99V5.4L Ffv V8

  • Automatic transmission
  • 50,000 miles

We purchased our Ford F150 in 2008 and have taken very good care of it but now once it hit just 50,000 miles we heard a loud knocking noise and we were told at the dealership that the engine is ruined and we need a new engine for the cost of $7,700.00!

With just over 50,000 miles on it!!!

F-150 XLT 8

  • Automatic transmission
  • 148,000 miles


5 months after repairing the first plug blow out, it did it again, this time causing a plug to chip off a fragment and go down inside the engine where significant damage was done, prohibiting repairs and requiring a complete engine replacement at $5765 plus labor, totaling $7000.

I called Ford Nationwide customer service to file a complaint. They just documented my complaint and offered no help.

I am definitely interested in filling a lawsuit/class action, or some other action against Ford. Can anyone help me with information/details.

F-150 Lariat 5.4L Triton

  • Automatic transmission
  • 61,292 miles

I am still "negotiating" with the dealership that sold us this lemon, as the quote to replace this notorious lemon's engine is $8k Canadian and I am still making payments on the truck itself. I believe Ford should have recalled these engines and I believe the dealer is responsible too as my husband asked about the slight "ticking" sound when we first purchased 22 months ago and the 2 salesmen reassured us this was normal. Not being a mechanic I fell for that one hook line and sinker.

After a diagnostic in October this year I was told I needed to replace the timing chain and do the cam delete. $1800 touch for that, and when this didn't fix the problem was told the engine is garbage now...so now another $8 grand? Can't do it, haven't that kind of money. I am very disgruntled with Ford for not recalling these notoriously lousy engines...shame on you. I will likely have to turn the truck over to the bank as I cannot justify nor afford the repair. And when it comes time for my mortgage to roll over I will be forced to sell my house because my credit rating will be garbage just like this 2008 Ford F-150 abomination of an engine. Never again will I buy a Ford...NEVER.

F-150 Harley Davidson 5.7L V8

  • Automatic transmission
  • 65,000 miles

driving to visit customer, engine starts to shake, thought oil problem as the car's electronics don't work well, warning signals don't work reliably. towed to Richport Ford and Lincon in Richmond, BC, was told the car needs a new engine. What the Fxxxx. anybody could help? opinions? should Ford have a recall on this as I could see that I'm not alone on this. Engine premature failure seems to be one of the major weakness on this model.

F-150 XLT 5.4L Triton

  • Automatic transmission
  • 154,721 miles


I Purchased This Piece Of Sh*t 1 -18-13 Had 130,00 Miles, A Year Later it has 154,721. I Have Worked On It Starting about a month after I purchased the vehicle, first the cat mufflers, then the cam phaser, then the VCT Solenoids, now the timing chain set. After fixing the timing, set water pump, oil pump, you name it, and thousands of dollars later, drove the truck less than a hundred miles to trade the piece of sh*t and it broke down. Now they say I need a new engine.

After purchase price with repairs I have over 18,000 thousand dollars in this truck that won't run, can't even use it for my job. FORD MOTOR COMPANY IS THE SORRIEST CAR COMPANY OUT THERE. Every Car Company has issues but FORD WON'T STAND BEHIND THEIR 5.4 TRITON MOTOR THAT IS BAD, REALLY BAD. I Won't ever buy another FORD FIX OR REPAIR DAILY VEHICLE. FORD SUCKS, CHEV RULES F===== FORD.

F-150 XTR 5.4L

  • Automatic transmission
  • 61,110 miles

I brought the truck to the dealership where I purchased it and my last f150 which was a 2003, with a complaint about engine knocking at low idle and what sounded like lifter noise, as well as what sounded like an electrical short when signaling a right turn, the service adviser and a mechanic came out and listened to both issues, and said they felt the engine noise was an exhaust leak, and would have to look further into the electrical problem. I booked my truck in and left it with them for the day. At the end of the day my truck was ready (or so I was told) I signed off on the work order which stated only: repair exhaust leak and determine electrical issue right turn signal. They had indeed fixed the ticking noise that they said was an exhaust leak, but I was no more than two blocks when the electrical short noise returned, not a big deal, I went back and they said they would have to look further into it.

This was the least of my problems, I was soon to find out that they had not addressed the engine knocking issue, which got worse at 103,000km. I took it back to the dealer and advised that they had not addressed the knock issue either, and was informed they had no record of me complaining of a knock. (I am furious, this is the second time this dealership has been told to check out a problem while addressing other issues, only to state after warranty is up that they have no record of the complaint. The first was on my 2003 when I had it in for service and asked that they check the four wheel drive, as I felt it was not always engaging, and was told it worked fine. The truck left me stranded 28km in the bush 3000km after warranty was out. No record of the complaint!

Through internet research I have since found out that this is a common failure that Ford is aware of, which is cam journal bore failure (due to lack of lubrication) which I am told Ford is blaming on the Fram filters that I am using, however I believe it is caused by the poor lubrication qualities of the 5w20 oil Ford has switched to in order to keep emission ratings low so they can produce more vehicles annually. My 2003 still runs strong at 347000km no thanks to Ford, they were also using this oil back then but I switched to 5w30 from my first oil change on, guess I wasn't smart this time as i followed warranty guidelines.

F-150 XLT 5.4L

  • Automatic transmission
  • 63,000 miles

I had the cam phasers replaced about a month ago. It started rattling a few weeks later. The engine light came on this time. I took the truck back in to the Ford dealer and he said that the engine was junk. I look online and see that there are a lot of folks that have this. I run almost all highway miles and ford tells me that it is the wrong oil or filter.

I spoke to an ase certified auto mechanic and they said there are a lot of these in 2004 to 2008 5.4 and 4.6. I am awaiting a call back from Ford on warranty as I have over 60k miles on it.
