    2015 Expedition 3.5 EcoBoost – slow coolant leak at driver-side turbo, looking for input

    I bought a new 2015 Expedition Limited 4x4. Never wrecked and passenger use only (no towing). One of the turbo coolant lines began to leak coolant. I had the Ford Premium ESP, which covered the repair. (At the same time, the engine vacuum pump began to leak oil - also repaired). This was in...

    Daughter's '15 going into limp mode, but is ok after re-starting (for awhile).

    Have you checked the battery terminal connectors and battery posts to ensure they are clean and tight? Are you SURE the battery is in good condition? If was common for the positive battery terminal and connector to corrode due to battery fume leakage and the red vinyl cover over the post. I...

    Transmission got hot - fluid everywhere

    From afar - if the transmission fluid cooler had an obstruction, it had to come from inside the transmission. I suspect with the overheat, fluid loss, and obstruction in the cooler - that you will have more problems soon with the transmission.

    Keeping radio on at drive-in.

    I don’t have an answer - but wouldn’t you run-down the vehicle’s battery if you used it for hours while watching a movie at the drive-in?

    The increase in ethanol percentage does not increase or decrease the octane rating. However, ethanol has less energy per volume, compared to the same volume of gasoline (about 30% less). This results in reduced fuel mileage. If you use mid grade gasoline that also has an increased ethanol...

    Rear A/C not cold

    Or your rear HVAC temperature actuator is not working properly, allowing heat to mix with the a/c cold air. The a/c system is on one refrigerant charge. If the front is cold - the rear evaporator would be on the same charge. It is possible the rear evaporator has clogged fins, but very...

    2019 Expy AC fan briefly surges during acceleration; Fixed-loose turbo inlet pipe

    There was probably a vacuum check valve in the vacuum supply that was damaged or disconnected during the work. OR - an IWE vacuum line damaged or left disconnected. The vacuum check valve prevents a momentary loss of vacuum to the HVAC system. A leaking IWE vacuum line will cause vacuum drop...

    Start with foot on brake

    I don’t have an answer - but I’m curious. Why would you want to defeat this safety interlock system for starting the engine?

    Why won't it start.

    You have a bad battery, probably with one or more bad cells.

    roaring noise

    Does the engine have electric radiator cooling fans, or does it have a belt driven cooling fan with a coupling that engages with speed? The mechanical fan coupling can fail and cause a roaring noise.

    Thumping sound

    One of the rear HVAC actuators is probably defective. The thumping noise is from it repeatedly trying to adjust.

    Door speaker rattle

    I vaguely remember a post on this forum with the same complaint - but I think it was a 4th generation model. The solution was to add some foam padding under the door panel (or radio grille?) which stopped the vibration and rattle. Perhaps return it to the dealer for diagnosis and repair under...

    Getting ready to replace pads

    Your original equipment Motorcraft brake pads lasted 100,000 miles - with some wear left. You are asking for a recommendation for brake pads. I think you answered your own question.

    Dash Fan Setting 1+2 not working

    I’d suspect the HVAC speed control (resistor unit) that fastens to the lower HVAC case, under the glovebox area. Check the wiring connector for a tight and clean connection, with no signs of charing. If the wiring and connector is good, you could replace the fan speed control unit (which...

    What Does Everyone Think About This

    I didn’t watch the video. GM also had problems with the data they were collecting and selling through OnStar: https://gmauthority.com/blog/2026/01/ftc-says-gm-and-onstar-were-watching-and-selling-your-every-move/ It seems to me that the issue would be simple for the courts and the NHTSA - I...
