glseibert Report post Posted July 1, 2009 Imagine driving through town and you notice the temperature hasn't changed since you left the house this morning. Garage was a cool 62 degrees when you went to work which is about 2.5 miles away (lucky). After work drove to the grocery store. By this time, it was well above 90. Display still said 62. Huh? Broken already??? To the friendly neighborhood Ford dealer to have it checked out. They say: Works as designed. You have to be moving along at least 25 MPH for 90 seconds before display adjusts in the upwards direction. Then it will adjust 3 deg/min so long as your speed doesn't drop below 25. The designers were trying to ensure the engine compartment heat would not affect the display. How is it possible to maintain such a speed for that duration in town? You're lucky if you can go 1/4 mile without hitting a light or stop sign. Seems like a software design error maybe? Wrote a letter to Ford. Got the canned response, "Bummer Dude. Deal with it." No other vehicle we've ever owned with a built-in external temperature does this. Sure it reads hot until you're moving along, but that's to be expected. Oh well, except for this, we're happy with the FFH so far. Quote Share this post Link to post Share on other sites
Oman Report post Posted July 1, 2009 I design software for a living. To me that's over-design. You move the sensor to a good location that minimizes distorted readings. You might make sure the car moves a minimum distance to make sure the sensor measures the air rather than the sheet metal but wow - they made it more complex than needed. What they did not consider is that the software design makes the sensor appear to be worse than what their software was trying to correct for. If they would have blanked the reading until the car met the criteria at least they would not be giving a bogus reading, instead they are showing a way-off reading to avoid showing a partially-off reading. Not an improvement. Jon Imagine driving through town and you notice the temperature hasn't changed since you left the house this morning.

treeofliberty Report post Posted July 2, 2009 This certainly is a stupid design, especially on a car that is littered with innovation. We live in Phoenix, and are used to seeing temperature guages reading in the 120's until getting moving. Sadly, it sometimes only falls to 118, because that really is the temperature. I agree with Oman, they're fixing a problem that doesn't exist. Quote Share this post Link to post Share on other sites
glseibert Report post Posted July 2, 2009 Thanks for the emotional reinforcement. Having been in the software development business for 30 years, my reaction was the same as Jon's. Now, if I could only find where they stored that literal 60 in the flash... <Dream sequence> I wonder if the gas versions share the same sensor management code.

Ranger_Rick Report post Posted July 2, 2009 Yes, the external temperature reading is odd. This has to be some sort of Ford Corporate rubber stamp.The rubber stamp that gets my goat: you have to runthe wipers in order to get a squirt. Didn't they ever thinkthat my windshield was covered with ice and I wanted tosquirt some deep blue de-icer without ripping my bladesapart? In the past, they have fixed my wiper motors underwarranty, because of this behavior...Also (drivin' a not a NAV) the little button LEDs are hard tosee. Maybe I'm gettin' old...

smr2112 Report post Posted July 2, 2009 That is dumb. Anybody who has one of these in their car knows that the readout is inaccurateuntil it's accurate! Overdesign...yea, you got that right. Quote Share this post Link to post Share on other sites
