F150 3.5 Liter EcoBoost ISSUES
Just my experiences with my EcoBoost, not bashing Ford and deffinatly not bashing the Cox Motors that are stuck trying to figure out what Ford Engineers cant.
At 78k miles here are the issues I have had with my Ecoboost:
1. Intercooler (CAC) moisture, truck stumbles on hard acceleration. Somewhat repaired, band aid was re-flash PCM and prevent air flow thru CAC so as not to cool the air as much (condensation averted). Isnt the purpose of the CAC to provide cold air to the engine?
2. Truck continues to stumble and now throws a P0306 (misfire #2) code. Cracked coil assembly. Coil replaced, my dime.
3. Truck continues to stumble under a load and throws several misfire codes at 45k miles. This goes on for SEVERAL months. Carbon arcing on 4 of 6 spark plugs. My Dime.
4. After purchase, started noticing a particular noise. I was told that all EcoBoost do it and its normal. At approx 73k miles, brakes have no assist for much longer at start up. Electric motor driving vacuum pump is the culprit. MANY other EcoBoost are doing this. Easy change, I replaced it myself but the Vacuum pump is $600, my dime cus ALL EcoBoost do this.
5. At 78k miles and start experiencing loss of power, no pattern but I do notice turbos aren’t spooling up. Eventually it throws a P0016 code which relates to crank and cam timing issues. Local dealer says everything is within spec and will contact Ford Engineers for probable course of action. Ford Engineers say….. Check oil psi, scope timing chain, disassemble front of engine. Once accessible, inspect timing chain, phasers (one on the front of each cam that controls timing), phase solenoids (one for each phaser), and oil passages for obstructions. Other than the timing chain and the oil passages, no clue what they are inspecting for and ford engineers are NOT 100% positive that any of this will fix it, they are throwing darts at my dime AGAIN.
Oil psi check ~$75 (labor)
Scope Timing Chain ~$75 (labor)
Access to inspect Timing chain and phasers ~$1200 (labor) Front of engine has to come off (timing chain cover)
Timing chain with slides ~$140
Phasers ~$150 each x 4 cus they have no idea
Phase solenoids ~$150 each x 4 cus they have no idea
Assorted seals and gaskets ~$?? Unknown.
6. The advertised 22 MPG… Horse hockey.. I reliably got 15 MPG unless I was doing 50 mph then, I could get 18-19. Comparatively speaking, the loaner I got is a 2012 F150 that has a 5.0 liter in it and is an XLT, same route to work.. same person driving, same driving habits and its getting 18.2 mpg. So much for the ECOBOOST being ECO friendly.
7. Newly discovered EcoBoost issues that I have yet to experience.
That black sooty exhaust that is “NORMAL” is causing a build up on the valve stems. Ford has no way of cleaning due to high temps of exhaust gasses melting seals in the turbos, and performance WILL suffer.
Many rear ends having issues with the pinion shaft bearings
As of 10-3
I decided that since I am paying for it and I only want to pay for the labor once, they are changing the Primary and both secondary timing chains and tensioners, all 4 VCT's, and all 4 solenoids. Funny thing was when I was talking to them about the cost of the parts, my dealer had marked up the parts 110% over cost. I googled one of the part numbers and found the part for half of their cost and told them that I will order all parts and provide them with the parts. They have since decided to only mark up the parts 10% above their cost
The dealer nor Ford are stepping to the plate to help out with this.
Timing Chain is on national back order. Truck has been in the shop now for 3 weeks now. Good times right?
