I took delivery of a 2024 Maverick on Sept 20th.. The recall had been issued, but It wasn't till about 2 weeks ago FORD ordered dealers not to sell..
The Recall states - it's a software fix...
Now it involves the camera picture "Freezing" while in reverse.
My odometer last nght when I got home is 2999.5.
I have obeseved that on backing up my camera has "hesitated" like when streaming on a poor internet connection, But no internet.
I did some experimenting as I retired as Senior Field Engineer for a Global Computer Company. I was 2nd-3rd level support.
The backup camera does not hesitate when listening to AM-FM radio but if connected to a smart phone. via USB cable the computer is decoding digital streams while decoding the back up camera and there is an interupt problem...
Years ago Digital Equipment Company (DEC) solved "real time" computing by using a interupt priority scheme.. That blew IBM out of the water... As a DEC computer prioritized it's routines and if some hardware came knocking that had a higher prority, i would exit it's current routine, place where it popped it on the "stack", service the interuption , then "pop" the stack and go back to where it was. That became known as real time computing. DEC also had a NMI -Non Maskable Interupt.. which was the absolute top priority in the sysem.. Quite a cool computing scheme. if you go to the NEW Smithsonian Air and Space museum in Chantilly Virgina, there is a NASA mercury control room mock up.. and there sits a DEC PDP11/45... a 16 bit real time box, I used to work on in 1979....
Frankly what I "see" or summurize the CPU/GPU in the "entertainment center" of the maverick has little computing power.. Probably that of a free cell phone they give away if you sign up for cell service..
I have a computer that is about the size of a stick of gum, that runs faster than what i see in my Maverick.. That being a (RPI) Raspberry PI ZERO W 2, that hobbiests buy for $15 in single lot quanities and they even have a camera plug in that doesn't hesitate...
Associated Press (AP) has 2 RPI's and 2 color cameras in MEXICO CITY, MEXICO.. It looks at the volcano down there and if it detects motion (ERUPTION) it start streaming to the AP Data Center in Kansas City. I knew the guy that designed it..
So my personal opinion the CPU Ford uses is an almost antique as it's 3-5 years old in computer time. it's not that it can't handle the camera, it can't handle the camera when it's also multitasking the ford pass app, the drivers cellphone connection, engine stuff, blah,blah.. that's why it freezes, or hesitates. Why I know? when you play AM-FM radio there is less computing going on than when you are streaming itunes and decoding the digital stream to analog audio. unplug the USB to your phone, listen to the radio, or turn it off and the backup camera doesn't freeze..
The poor computing power may be why there is no 10 device wi-fi router internet connection that according to my sticker is in my car but it isn't.. One of the reasons I bought the Truck.
