2018 GMC Sierra 1500 UNKNOWN OR OTHER

The truck started to vibrate or shudder . We are having to deal with replacing the transmission on our truck, which has only 45,000 miles on it. We have noticed numerous complaints about transmission problems with this model and the place that is replacing the transmission said they have had 3 customers in the last couple of months with the same issue on the same GMC model. This is a lot for our small town and area. Why hasn't GMC issued recalls ?

Like many of the 2014 and 2015 models, my vehicle has experienced the exact same failure in the radiator due to the thermostat over cycling. There is already a TSB for those models, yet GM changed nothing in the subsequent models and the problem persists.

Vehicle is shaking at highway speeds

AC condenser went out on my vehicle with 100,000 miles, lots of reviews online stating this is a known problem but yet there is no recall. Torch Converter going out at 80,000 miles.

I have had my truck in the shop several time for the rear springs they finally replaced the springs and I am having trouble again my warranty is out but I took it to see if gm would take care of the problem but they don’t seem to want to do anything and I no my vehicle is not the only one that has had this issue

My rear back heated window on the passenger side popped and shattered the window while I was sitting in the passenger’s seat waiting for my husband. The truck smelled like a sweet wire smell and then I heard a loud pop. I looked back and the back window panel was shattered. I do see that there were recalls on some of these windows.

Sunroof shattered while driving on the interstate

In short, the moonroof of my vehicle spontaneously exploded into a million pieces one morning while driving.

Constantly getting “service trailer brakes system “

Air conditioning condenser failed at about 48,000 miles. Seems to be a common problem that is a design defect.

The radiator developed a leak on the drivers side. This caused a loss in antifreeze.
