My truck was updated last Tuesday. I drove it through the weekend with temps betweeen 16-30 (with snow/ice in the road). Did not get the trailer disconnected error all weekend which had not been the case for the past two months. I have not been able to get to the dealer myself to get details but will attempt to do so once I am back in town. Note that my truck does not have the lane assist or park assist features so I am not able to verify if the update has any effect on this errors.

A software fix has been released. I have been pushing hard on this for the last two months and received a call this past Monday. You can look back and see that another individual received the same information that day as well from his dealer. My truck went in on Tuesday but I was out town so I have just been home for two days. No issues so far - but the temps have been above 22 (seems to be the magic number for my truck). This weekend we are getting back down into the single digits so I will see how it goes. As suspicious as it seems I believe it was just lucky timing that dealer was able to give you that response. What we don't know is if this software fix has been fully regression tested and will alleviate the issues.

My truck went in and came back yesterday with the "new fix". I am out of town so the wife took it in. She said the error popped up that morning and she did not experience that evening when they brought it back to her. I get back tomorrow and temps are supposed to be below 20 all weekend so I'll get it out this weekend for a better test. Ironic this fix showed up right after I had a buy back request submitted and the attorney general's letter arrived at the dealership (submitted a complaint online to start procedures around the lemon law). I am going to assume that since they are telling others 7-10 days that I may be part of their QA process on the new program... or they just took it in to buy some time. At this point neither would surprise me.

Was this in the past week? Originally the issue was thought to be resolved by removing moisture from the connector or a factory reset on the infotainment. They are claiming now that a fix has been applied to the code and that code needs to replace the existing. This was just announced today from what myself and others have heard from dealers.

Just received a text from the sales manager at my dealership. Said they are coming to get my truck and reprogram it this week. Good to hear that someone else has heard the same. We are expecting lows in the single digits this weekend and it has consistently had error messages when the temps fall below 20. Should be a good indicator of the reprogram works.

Gentlemen, So far I am still struggling to get a response from the dealer or GM on this issue. However, I have been able to push the issue with GM by using social media. On Friday evening I started replying on twitter, Instagram, and Facebook to various posts by GM about "how great the new trailering technology is" and also on GM's CEO's twitter account. I did the same on the dealership's social media accounts. In response I did get a response from the team that manages the CEO's twitter account. I have provided them the details of the issue and my current case number with GM (which I was told a buy back request has been submitted). As you are aware the effect of social media can cause some movement where other attempts have not - yet it takes more than just one. I've copied the post I replied to below so that each of you with this issue could do the same. I believe that with enough 'bad news" listed on the CEO's twitter account and elsewhere in social media GM will start to take this serious. I also encourage you post on GM's facebook and Instagram accounts as well noting the error (with pictures is always a plus). I realize this is a shot in the dark, but as you can tell based on 9 pages of posts that GM is not committed at this point to resolving the issue. I am hoping with some pressure from social media, my buy back request from customer services, and the case open with the attorney general this may actually get resolved or at least a replacement vehicle. https://twitter.com/mtbarra/status/1098230059901636609

I contacted GM at 1-866-522-9559 and they were able to open up a case in which one of their "specialist" will contact me in two business days to start the buy back process. We'll see how this goes next week but at the very least it is another avenue to make some more noise.

Grabbed mine from the dealer and drove it during the warm weather last weekend and experienced no issues. Just got back in town and it’s 24... took the truck to dinner and within 2 minutes same error. Calling GM tonight or tomorrow to start the process to get them to buy it back and taking it back to the dealer to log the error again. Figured that might light a fire under someone’s ass if they have to buy it back.

Just dropped mine off at the dealer for the third time for this issue. Less than 300 miles since I bought it and in the shop three times in less than a month. I told them for $50k that I refuse to accept the answer "we'll call you when we figure it out". Told them to keep it until they can fix it.

Just heard from my dealer as well... There is a new "plug" which he described as the trailer plug/connector that you attach the lighting harness. He also mentioned that there is an update to the programming as well that will be coming "soon". He was under the impression that the plug/connector is available to order and they will be getting the part number from GM tomorrow.

They contacted GM and are waiting for them to respond. Hopefull will have an update tomorrow sometime. After reading these posts I am not real optimistic

Same issue here. Less than 600 miles on 2019 1500. It's at the dealer for the second time in less than three weeks (2 of those weeks it wasn't driven). Took it out in the snow five blocks to grab a bite and on the way back home constant trailer disconnected messages on the dash. Dealer told me today it was water/moisture in the sensor again and I would just have to deal with it until GM has a fix. Calmly told them that was unacceptable and I would pick the truck up when it was resolved or they can take it back.
