Vibration at highway speeds when vehicle is cold.

Is anyone getting vibration on their Jeep Grand Cherokee L when they first start the car in the morning in cold temps & drive at highway speeds 45-65? Been having this issue for about 2 months. Took it for service, but they're saying nothing is wrong as they couldn't replicate. My guess is that by they time the test it the car is warm and issue is gone. Thoughts?

How cold? Does it sit outside? Could be your tires have a slight flat spot when sitting overnight and the cold will cause it to stay that way longer. Once they warm up, vibration goes away.

The car sits in a heated garage....been seeing this issue anywhere between 40 degrees and below. Started watching the transmission temp and thinking that could be the issue, but can't say with 100% certainty. Never had this issue with any other car before, but this is my first Jeep and not sure if it's considered normal.

I haven't noticed any vibration from the cold but I do have a very loud exhausted drone when it's below freezing.

I had this issue on a 2019 Jeep Cherokee. I am fairly certain that it was the tires. When I drove it for a couple of miles, the vibration faded away. Have not noticed it on my 2021 JCL .

My GCL has a vibration when i put it into Drive and leave my foot on the break and haven't even moved yet. I think it only started when it started getting cold out. The only time i notice it on the highway is when the RPM's go under 1500.
