Cold weather errors (trailer connection & sensors)

KA0S · March 2, 2019

So the salesman called me today saying that GM have solved this issue with a software update (seems suspicious that the day after I said I wasn’t going to buy the truck that they magically found the solution) and that other dealership will be getting the news on Monday.

I asked for details about the update and he couldn’t tell me anything.

has anyone else heard anything ?

Scroll up in this thread. People have mentioned there's a fix that's supposed to be correcting the errors.

I just got mine a few hrs ago. They had it a day and half. Forth trip to resolve. No fix yet. They said it is there top priority. I did get a nice wash.

If someone actually gets a fix, please post the info. I was told they are still working on it. First the thought it was the trailer connector, then wiring to it, video module. There is a very suspicious common ground running between systems.

Has anyone’s side detection stopped working? Mine completely and they don’t know what is wrong. Think it is tied to the rest of the issues.

be careful if towing, running lights go off also when cold outside, stop truck restart with trailer connected and running lights stay on for only a short time. all other lights and brakes working. towed yesterday for 5 hours in the dark with no trailer lights. dangerous and gm has no fix?... been to dealer twice , no fix . so have to drive with warning flashing on dash and cannot tow trailer.

Been watching this thread as I’m going threw this exact problem. Took the truck to the dealer four times starting in Novermber. Four times not fixed. Last week I called GM and told them I wanted them to buy back the truck. They told me a “Senior Advisor” would call me within 2-3 business days. Today, March 4th, (the 3rd business day) she called and told me “there is a fix as of March 1st”. I told her I don’t care, it qualifies under lemon law (CT), I still want them to buy the truck back and that there is no guarantee that this fix will even work. Then she tells me it doesn’t qualify for lemon law “with them”, “because there was no fix for the vehicle”. LMAO!! It’s not my problem or any customer’s problem that the four times it was brought there, they could not/had no fix for it. Now, when I say I want my money back, they suddenly have a fix!! I had already contacted an attorney. I just have to email him the sale paperwork. I told her I would tell my attorney to take my case. Too little, too late....

The fix is to de-sensitize all the systems. U will find park assist barely works, side detection and pedestrian alert is after the fact. Cross traffic alert should be re-named, “there already behind you alert”They are dragging their feet hoping warm weather clears things up and a year expires.

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.

Opened my case, meanwhile im paying for a car to sit at the dealership and be torn apart and told thats normal. 1100 miles....keep it classy GM/Chevy

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.

Unfortunately, A manufacturer is never going to just buy you out. You will have to get a lawyer and press the issue under lemon law, if your particular case qualifies for it. I live in CT where the lemon law is two years or 24,000 miles. “A reasonable number of attempts to fix the same problem”, which I’m told is four. The “senior advisor” said they “never attempted” for fix it because there was no fix. Which is B.S. You can’t just tell someone it’s broke, we can’t fix it, wait MONTHS, too bad, so sad. They will lose in the end. They will eventually have to buy the truck back, minus some formula for mileage AND pay for my lawyer fees (part of the law). It doesn’t happen overnight, but it will happen. It’s really too bad. This is my first GMC, it’s a beautiful truck and I love it otherwise, but this has been a horrible experience!!

According to the service rep, all the systems are related. Like I said above, they are de-sensitizing the systems. The rear sensors are part of the trailer stuff.

I really just want what I paid for. I am afraid it is becoming common knowledge the trucks have electrical issues which will kill the value even more than the 11k in incentives they will offer in 6 months.

Get the certified letter to them to preserve your rights. If there right, symptoms will going away this spring and summer but come back when it’s cold and wet.

This is happening on mine too. I’ve noticed the Auto Stop feature is not working either when I have these issues, along with making changes to the settings on the infotainment system.

Pretty frustrating that this wasn’t caught in testing.
