Extremely similar issue here. I've contacted support now 7 times about this. They just tell you to buy a new modem and after you buy that new modem, they just want to keep rebooting it to clear the counters...
They are finally sending out a tech tomorrow to inspect the lines between the house and the tap.
I will update here with any findings.
Update: 1/12/2021
I got a service rep out to the house. They immediately pointed out that the Cox lines from the tap to the box on the house, and from that box to the hole in the wall were terribly weathered. After he replaced the cables, the problems persisted. He also ruled out all hardware on my side and dropped a bunch of jargon claiming that the problem was at the tap and is going to put in a ticket to engineering to check/replace that tap.
I bought a new modem “ARRIS SBG7600” three weeks ago and I’m still having the same issue. I have had three techs come out and say there’s nothing wrong but none of them ever try and recreate the issue while they are here.

I’ve been having this issue since 9/04/2020 and my issue is that my gateway keeps throwing T3 and T4 errors

I know how frustrating it is to have no resolution while having internet issues. Are there any splitters or amplifiers that are connected to the coaxial that is screwed into the back of your modem? If so can you bypass the splitter/amplifier and plug it directly into the wall from the modem?

No amps/splitters. Cable was a straight shot.

The tech that was out here today for me told me T3/T4's relate to the coax connection to the outside tap. Inspect all the coax leading from your modem, to outside, to the tap. See if the cables are insanely weathered/crumbly.
