C-Link or Toe Link Disconnect

[Sacagawea]

We were heading out for vacation. Would be driving my R1T for a couple of weeks in the Northwest and Vancouver, Canada. Just days before we left an "update available" popped up on my screen. Let me preface this with I have had my vehicle for 2 1/2 years and have been hit or miss on successful updates. But did not want us driving extensively with this constantly on the screen, hitting it by accident. So I updated. We left for our trip from New Mexico to Oregon.

Things were fine for the first days, but if I'm on the Forum you know there's more. Fifteen min. from Tualatin, OR it felt like we got hit in the tailgate. Continued driving a bit more but kept happening. Feels like being in a gas car when you step on it to accelerate and it hesitates at first then suddenly "kicks" in. Taking it to Service Center in Tualatin they thought it might be what they called a "C-Link Disconnect". Described as the motors (my R1T has the dual motors) when I accelerate or decelerate, the rotation is not sinking up. They also checked to make sure everything was put back together right after the recall. (I had the recall update/Toe Link done in September, they couldn't fix it totally and it was towed to Colorado. Fixed there, no other issues.) Said it was fine, we got our truck back a couple of days later.

On with the trip...until...we got to Crater Lake. Yep, barely made it up the rise to the lake. Long story not short we had to tow it back to Tualatin. Had it for a couple of days, checked it, tested it, no issues. There was one nagging factor for me, the update. It had never had this issue Ever before. He tried to say that was just the way it was. Uh, no. I asked if an update could change the mechanical functioning of the vehicle. Reluctantly he said it could have.

Now what. Online searches basically say I'll have to live with it by driving in Sport Mode from now on. Can I just go back to the previous update? Wipe my truck's memory? Ugh. Anyone else have this type of issue or am I just the lucky one?

The disconnect can fail. Did they replace it? I think they usually replace the entire rear drive unit when that happens. Sport mode keeps the rear motors engaged all the time so you don't keep connecting/disconnecting. But that's not a solution really if the disconnect is going bad.

So they ended up doing nothing? Because it's just going to get worse if it's the disconnect.

The last update was like a month ago. What version are you running? Since updates are so frequent, ALL problems show up within a few weeks of an update. AFAIK they haven't messed with the disconnect timing in a while - does it say anything about that in the release notes? Regardless I think it's highly unlikely that the update had anything to do with the problem.
