I have a 2014 SHO that just rolled over 120,000 miles. I have owned the car since just under 60,000 miles. Up until recently, the car has been outstanding. Recently, it seems like everything with this car is starting to fail.
Around 118,000 miles (April 2025) the car started smoking a little and the car felt down on power, no codes or anything but it sounded different - higher pitch when under boost. I checked front turbo and it was failing and starting to grind itself down. Parked car, figured it was a good time to do the timing chain and water pump and replace the turbos. I replaced the turbos with upgraded GH turbos, cleaned out GH intercooler and eco power parts pipes from oil from failed turbos, new brakes and rotors. Flushed / changed all fluids; rear diff, ptu, transmission, power steering, brakes. Took car into dealership for timing chain and water pump in mid June. Received car back from dealership on June 21.
Car was given perfect bill of health from dealership.
Everything was great for about a month after this. I have been working with Brad on dialing in the tune with the GH turbos and the car is a fantastic daily driver.
Late July, the touch sensitive hvac controls started randomly doing their own thing and not responding to my inputs. Luckily all of that is in its own menu on the infotainment screen.
Early August, backup camera develops issue where it will show me a black screen, a screen with no parking lines or it will work as it should.
Mid August, car starts smoking on cold startup (oil). I check catch can and it is full. I empty it and everything is fine for a few days and then starts smoking again. Check catch can again, its full. I realize that I never installed my UPR catch can. I did that last weekend. Now, anytime the car comes under load, it will shoot the CSS (what replaced the oil cap) clean off and oil gets sprayed everywhere (replacing the oil cap with something that has no way of securely locking down is just a stupid design). In the last two weeks, I have probably dumped 8 - 10 ounces of oil stuffs from the catch cans - not including whatever sprayed out when the stupid CSS comes off.
So now, I am trying to figure out if I have some type of crankcase ventilation issue or some other oil issue, hopefully not related to the turbos. Any suggestions on where to start? All of these issues are starting to wear on me.
Edit *** Forgot to add mods: gapped plugs, 3 bar map, 170 thermostat, GH IC, GH Turbos, PPE Downpipes, XDI Evo HPFP, Eco Power Parts Dual intake and hot pipes, ssm mounts, tuned by Brad - AJPTurbo.
As for the planned obsolescence, my coworker has a 2014 or 2015 (she isn't sure) Ford Flex with the 3.5 ecoboost with 125,000 miles and it also started smoking (oil) the same week mine did. Her backup camera also just started having the same issues and her hvac controls haven't worked in over year. So, it seems like around 120,000 miles is when this platform just gives up.
