I randomly stumbled upon this issue when I started my car one morning about 4 weeks ago. I haven’t found anyone else online with this issue and I’m absolutely stumped. I ordered a brand new LCD and digitizer unit through Tanin and I just went in and replaced it, plugged everything back in and the exact same issue is still occurring. There are random pixels messing up and none of the screens load properly, as well as random touch screen buttons getting pressed, mainly on the climate control screen.
Please somebody save me this is driving me nuts, if anyone knows anything I’d greatly appreciate it.
Do you happen to mean the ribbon cables attaching the LCD to the motherboard or all the connectors that plug into the back of the Nav/AC unit?
Start with the actual plugs and of no difference a light spray on the ends of the ribbon cable with light pressure coming out of the can. Allow a few seconds to fully dry

Just went ahead and took it all apart and cleaned all the connections as well as the ribbon cables, unfortunately the same exact problem still persists once I plugged it back into my car. Any other ideas by chance?
edit: another thing to note that may or may not help in figuring out the issue; The screen will occasionally restart itself when I turn on the climate controls.

That edit makes me think you have a short in the wiring somewhere.
I will go ahead and run a continuity check, but could a short in the wiring really just happen out of the blue? I've owned the car for 2 years with 0 issues and one day this randomly occurs, is that really possible?

Absolutely. You could run synthetic oil and change it every 1,000 miles and when you take your car in you puzzled why your problem are coming from cam lobe wear. Sitting there your like how is this possible I do this and that.
It's a car. Road terrain and bumps is different for everyone. Along with a host of different issue. Also if you had your dash replaced under the door dash and door panel warranty campaign it's quite possible a fellow the pinched wires.
Happened at my dealer. Although the wires a tech now no longer here at my dealer pinched the tpms wires. Talk about annoying problem for a customer. Poor guy thought he was low on pressure all the time.
Maybe you leave the car outside and there could be water leaking, or from the AC or system now that you say whenever it is turned on it reboots, condensation etc.
Simply the unit is bad... I bought once a Dell tower, on its first reboot, hard drive died. Had a Nikon D70, out of nowhere it will charge thru the camera charge port or transfer data, had to remove memory card and battery. Unfortunately it just happens.
Good morning @KimballG
I'm sorry to hear the LCD did not fix your issue. We have seen this happen with bad motherboards which result in replacing the whole unit. If you would like a quote on a replacement unit please send us a PM.
