I seldom drive our 2021 Trailblazer RS because my 2002 Chevy Silverado is more comfortable. This week I have been driving to and from medical facilities with my wonderful mother-in-law to Portland Oregon on freeways. I noticed quickly at freeway speed a feeling like alignment is towed in. When entering a freeway corner at 70 mph (especially to the left) the resistance you normally feel in steering feedback goes away and it wants to turn left by itself. It is very uncomfortable feeling! I checked tire wear and air pressure and they look fine. If I keep both hands on the wheel and anticipate it then it is not too bad. My wife says it feels that way to her too. I cant take it into a dealer presently because I have to continue to do the medical trips for a while and the truck is not easy for her to get in. Has anyone else has this strange feeling while driving freeway speeds?

FWD or AWD? Do you have "sport mode"? If you do does the problem go away when sport mode is on? Do you have the "lane keep assist" turned on? If you do it will try steering itself to keep between the lines.

By any chance is the lane departure system on? The system does have a little steering effort to guide the vehicle back away from the centerline and edge line. It is turned off and on in the front console next to the stop engine switch.

Thanks for the feedback! It is AWD. The lane assist just last week decided to work when our battery ($200.00 AGM) died. I will try sport mode. Great hints!

If this is your first Chevy/GM product, I’m sure you’re just not used to the way they do their power assist steering.

seems like everything after like 2012 adjusts based on your speed (my prior two Cruze models were like this, you BARELY had to touch the wheel to make it go around an interstate corner). The trailblazer feels almost identical.
That said, I usually run my TB in sport mode on the highway because the steering is just way, way too loose and trying to keep it in lane on a windy Midwestern day is just more trouble than it’s worth without the stiffened steering with sport mode.

Betting it was the lane keep assist. Hope you can get it taken care of if it's not.
